Fring VoIP being sold pre-loaded on some Nokia E65s

Saw an interesting poster in the window of one of my local phone stores - a Nokia E65 with a logo saying "fring enabled - Instant Messager & VoIP".

I had a chat with the guy in the shop and he said that they were selling them primarily together with Orange contracts, usually with either just 4MB or 10MB of 3G data per month, although he seemed to think this was ample for most peoples' use of VoIP over the wide area. He said that the T-Mobile T's & C's on Web'n'Walk prohibited VoIP, although one of his friends had been happily using Skype over cellular with no problems.

What wasn't immediately obvious was where in the process the fring client was being installed on the phones - it certainly didn't seem to be operator-specified, so I imagine it could just be the retailer (not a big chain) gets them preloaded from a distributor.

On a separate note - I see quite a few E65's in circulation for general consumers, rather than enterprise customers. This particular one was in a very non-corporate shade of crimson red.

Some more clarity on xG Technology's xMax

I had an update meeting this morning with the xMax management team, and got a chance to grill them a bit more deeply on the current plans & business model. I last met them in late 2005, so obviously there's a fair amount that's happened since then.

The first and most important takeout is what applications and customer types they're aiming at initially. It is absolutely evident that xMax is not aimed at service providers looking to compete head-to-head with dense, large-scale, telco-grade cellular networks with all the complicated machinery they require. Maybe on the far horizon if all goes fantastically well, but not right now or realistically within a 3-4 year view.

The target segment of operators is much more akin to a those that are happy with lowest-cost, best-efforts, ISP/VoIP provider approach. The base stations & infrastructure are aimed at competitive service providers wanting to create a bargain-basement, 'alternative' network that avoids the need to tackle complex wholesale and interconnect arrangements with incumbents (wired or wireless) except via Internet VoIP.

Now, there are quite a lot of service providers that would be happy to take the compromises involved - proprietary technology, no "name brand" handsets, little spectrum management, limited end-to-end QoS, no international roaming and so on. These are the same type of organisations that might also look at low-end WiMAX installations, or even the larger WiFi mesh approach. But it is important to stress that these are essentially wireless ISPs that also have a VoIP proposition - similar in many ways to WiMAX Telecom in Europe or niche UMTS-TDD players like Woosh in New Zealand. The difference is that those operators are starting with PCs (which can support VoIP) rather than phones.

All this is well and good - and may even enable 100's of thousands of subscribers in the US, where there's still a few million subscribers on regional cellular networks outside the 'Big 4' carriers. Many of these customers have limited service capabilities - even having to pay extra if they roam nationally out of their local area. But it's not going to quickly scale to millions of users per country for a variety of reasons.

The international story was also interesting, for example talking about its evaluation with Telefonica's Mexican arm. The angle there is to allow large players to enter into commercially challenging new markets at a low cost, not to replace their existing incumbent networks such as Telefonica's Spanish busines or O2. Fair enough as an entry strategy where it's hard (politically or regulatorily) to deal with incumbents, but again it's a bit of a lower-grade solution rather than a fully bulletproof one.

Less clear was the situation with other international markets outside North America, particularly with regard to spectrum. The company's position is that it expects its customers to have access to their own spectrum - but they were very vague about which bands were ideal, how much spectrum might be needed for a given application, or critically, how long it might take to support a new frequency band in the base stations or phones. I also found it slightly worrying that the execs were unclear whether necessary spectrum had to be designated for TDD or FDD use.

I specifically didn't go down the route of asking the company about the recent public spat with a Qualcomm employee (Phil Karn), who has aggressively been trying to 'debunk' some of the company's more high-profile claims for xMax. Nevertheless they proactively raised the issue & pondered on his motives. The execs didn't brandish statements about 'orders of magnitude' better performance but were keen to stress power efficiency. Given that nobody with an engineering background was in the meeting it wasn't a topic I wanted to focus on. Either way, I don't see worrying about xMax as exactly being #1 on Qualcomm's to-do list at the moment given its other predicaments, so I don't see Karn's mission as some weird conspiracy: I suspect he just likes an argument, although in my view there are better ways to win one than the route he's taking.

However.... the CEO did give me useful numbers which I hadn't heard before. Some other engineers may be able to get their teeth into these & yield some analysis.

Apparently, the 1st generation products should yield an aggregate of 17Mbit/s in 26MHz of spectrum in the US ISM band at 902-928MHz, after accounting for guard bands and overhead. Ultimately the company is aiming for 2 bits / Hz in this band, in what they refer to as a "4G" network. They are also intending to go for four sectors per site, yielding a total of 17x4=68MBit/s , or in later versions maybe 2x26x4=208Mbit/s
[edit - that's my calculation, and based on comments below I should have asked about spectrum reuse & probably a bunch of other stuff. Treat it as an upper bound, I guess]

If I'm reading the tables here correctly, that's good but not exceptional in terms of spectral efficiency. My engineering knowledge doesn't permit me to say anything about power consumption, though. Someone else may have a view on this. It's worth noting that range is a bit of a non-issue here as it simply spreads the given (fixed) capacity over a larger area. Again, possibly useful for a startup operator wanting to build up a best -effort network over time by adding base stations, but again that's not a viable proposition for a mainstream operator wanting to launch a large network on Day 1 without having to go back & acquire more lots cell sites subsequently while the network is already running.

There's a bunch of other issues I haven't touched on here that are also important especially around backhaul, standards, threats from US 700MHz services and regional exclusivity.

But my current bottom line is that it sounds like a solution for the "Wireless ISP with VoIP" market, but not a near- or mid-term threat to conventional cellular voice or data services. There may be some extra-clever stuff in how it does power management, but the rest of the solution is not 'telco grade', and it would take a long time to get there as there's no 'ecosystem' in place and no clear strategy to build one. Although they ultimately want to sell silicon, it's not obvious how (for example) Nokia might engage with the company to integrate xMax into its phones.

I've seen some recent comparisons between xMax and 3GPP LTE and major 802.16e WiMAX rollouts like Sprint's, and I think they're largely unfounded & unrealistic - they're completely different propositions aimed at different customer groups & usage cases. To my mind, xMax is more of a potential threat to low-end ISP-type WiMAX deployments, CDMA450 in rural areas, and the largest WiFi mesh implementations, especially in North America or anywhere else with 900MHz unlicenced spectrum. I'm unconvinced they've progressed much towards supporting other frequencies - they certainly don't seem to have any other obvious preferred 'profiles' for 2.6GHz or 700MHz or 2.3GHz or whatever, and given work I've done recently it would probably take a lot of time & effort to support even one of these to a reasonable degree.

(As with my previous posts on xMax, I'm going to be ruthless with comment moderation/deletion)

A plea to Yahoo about mobile email

Don't get me wrong, I love Yahoo Mail. I started with it in 1995 or whenever it was it first kicked off, and I still use it almost religiously for my personal messages.

I've been checking it on mobile devices since 2000 - initially on a browser on a Palm PDA, hooked up via infrared to a Siemens SL45i phone connected over GSM. More usually, I use either a handset's WAP browser, or a normal HTML browser on a smartphone.

Recently, Yahoo has messed up, though. A lot.

Firstly I played with it's Yahoo Go software on the trial N73 I had running on 3's X-series service. It was utterly, utterly dreadful, the single worst piece of mobile software I'd ever used. Slow, temperamental, didn't have a 'refresh' button so I couldn't see new messages immediately, limited memory. Just ugh. Worse than the 2000-era Palm/Siemens/infrared user experience. And much worse than just using a good HTML browser set for full web pages, downloaded over 3G on a Nokia E60 I was also using at the same time.

And now it seems to be trying even harder to mess up. I've got a Windows Mobile HTC device that I use for web browsing on a T-Mobile Web'n'Walk plan. Historically I've done 'pull email', checking Yahoo a few times a day. Worked fine. But now they've gone an 'upgraded' (!) the site to its new Mail Beta. Yes it's a bit prettier, but takes longer to load in, and stupidly only displays 5 messages per page, with no obvious option to let the user change it to 10/20/50 etc. Hello? Yahoo? Tell me - what's quicker, scrolling down... or going back for another roundtrip to the network? Let me see, outside of 3G coverage on T-Mo's GPRS, I reckon that's 0.3 seconds for option 1, versus 7+ seconds for option 2. And at least up until last week you still had Mail (classic) as an option on the main Y! menu, but you've now removed it. Put it back, NOW.

UPDATE: I've noticed something even worse about Yahoo's mobile beta email. It only loads in a single page of text from messages, requiring the user to click 'more' after about 10-15 lines depending on your screen size. This is outrageously stupid, and obviously straight out of some 2003-era book on designing a mobile user experience. Guys: phones have scrolling functions! People use them regularly, eg for scrolling through their contacts lists or message folders. This isn't rocket science.

Yahoo - I'm a (very) loyal user, so please, please take your mobile mail strategy back to the drawing board before I have to switch to someone else.

Google - why the interest in femtos?

OK, I'm a bit stumped by Google's investment in Ubiquisys the other day, unless it's a purely financial transaction - or unless Ubiquisys has something up its sleeve other than plain old 3G femtos.

Yes, I know that Google's talking about pitching $4.6bn for the US 700MHz spectrum... and yes I know that there's a 700MHz standard for UMTS going through 3GPP at the moment. But I'd have thought that femtos at that sort of frequency was fairly pointless, as the big attraction of 700MHz is that it's got great range & goes through walls easily.

The real advantage of 3G femtos in my view lies in 2100MHz 3G spectrum (ie most of the world today outside the US), and probably in the future in 2600MHz band. It's conceivable that Google might want to start bidding for those chunks of spectrum around the world, but I'm unconvinced that it's going to follow the classic cellular path (ie 3GPP UMTS or LTE) rather than something more Internet-like.

There's an outside possibility that Google might in fact want to do something with WiMAX - but at present Ubiquisys doesn't do WiMAX femtos, although chipset supplier PicoChip is certainly doing suitable silicon. Maybe that's what the investment's for....

European mobile TV standards.... what a pointless exercise

I see the European Commission is having another bash at encouraging the mobile TV industry in Europe to standardise on DVB-H. Various opinions abound, including one that this is fact a climbdown from a previous promise to get proscriptive now, rather than maybe in a year's time.

Maybe someone in Brussels has had a sudden attack of commonsense and realised that best standard to follow for mobile TV is not to bother in the first place. There's no massmarket demand, no obvious business model, and lots of better things to do with the spectrum. Sure, there are probably a few specific niches for mobile TV to be successful, but the idea that 10's or 100's of millions of people in Europe are going to be subscribing to them and watching avidly is pure fantasy.

WiFi BlackBerry - exactly what does it support?

I wrote recently about the new WiFi-enabled device from RIM. Now that the 8820 has been officially announced, I'm trying to get my head around exactly what the deployment scenarios are.

It seems that it does indeed come in both "operator-oriented" and "non-operator/enterprise-owned" variants.

The device's specific website for the UK has this to say about the WiFi functionality, which makes it seem like purely a service provider play:

Data Support
If you have signed up for a qualifying BlackBerry® data plan¹ through your service provider, you can also use your BlackBerry® 8820 smartphone to access your BlackBerry data services over virtually any Wi-Fi network.


Voice Support over UMA/GAN

If your service provider offers UMA/GAN support, you can also take advantage of full voice functionality² over any Wi-Fi network supported by your service provider


OK, so the much-rumoured UMA support is embedded, no particular surprise there. I guess the major use case will be so that employees on T-Mobile US can use the thing at home where coverage is lousy, and also in Starbucks etc. I see from the RIM website it's shipping France too, so I guess there's an Orange Uniq variant as well. The press release mentions AT&T - but unless it's done (another) volte-face it doesn't have a currently announced plan to support UMA.

But the data support option is the more weird one - does this mean that you need to get your carrier's permission before you use it on you own WiFi network? So if I'm sitting in my office, connecting to my exchange server in my basement over my WiFi - or going out over my local ISP connection... I have to pay my operator for the privilege?! Maybe this is what the AT&T reference is about in the press release.

Also still unclear is whether the device is usable by enterprises for non-operator VoWLAN. Can I put a Cisco or Avaya softphone on it and connect directly to my IP-PBX via the Internet, as you can do with a normal Symbian or Windows smartphone? Is there an addressable 'naked' SIP stack? Unfortunately the full specs for the 8820 aren't on RIM's website yet.

It could be that it's only designed for operator-managed dual-mode IP-PBX based solutions using SIP, such as BT's Corporate Fusion offering. I could see AT&T playing in that space as well.

On the other hand.... it's started selling direct via Carphone Warehouse in the UK, which can activate the devices on 3 different operators' networks. Sounds like RIM may be edging slowly to carrier-neutral distribution after all.

Truphone - 1, T-Mobile - nil

OK, it's still just an "interim injunction" and I haven't seen the full details yet, but it looks like the wVoIP industry just scored first blood against the mobile incumbents with regard to interconnect.

I don't have time to go through all the ins & outs of this yet, but on first glance it looks like another step towards 3rd-party VoIP on mobile being given a chance to compete. Obviously there are arguments and counter-arguments on both sides, but from my point of view the fact that T-Mobile blocked access to numbers that their subscribers could reasonably expect to reach was a step too far. While I certainly appreciate the desire of operators not to subsidise WLAN-capable handsets & then see that subsidy used against them, the notion that they can just arbitrarily block outbound calls to number ranges they don't like is ridiculous.

And they made it worse by announcing to their users "You have dialled an incorrect number. Please check it & try again" - despite the inbound call coming from that very same number. If the recorded message had been honest and said "Sorry, you've tried calling a number from an operator we're still in negotiations/dispute with, please call from a non-T-Mobile phone" I would have cut them some slack.

On the other hand, if you want a well-argued contrarian viewpoint, Keith over at Telebusillis had this to say the other day

UK mobile interconnect shenanigans

I'm buried in work so can't comment fully on these today, but I note that:

a) T-Mobile & Truphone are going to court on Monday about whether or not T-Mobile has to interconnect its normal voice customers to Truphone's shiny new UK mobile number range (delivered via VoIP rather than circuit-switched). I haven't waded through the respective legal documents in detail but T-Mo's lawyer wins the comedy prize for his comment on page 15 about the 'monopoly' of the newspaper seller.

b) Ofcom has ruled in a case about different interconnect prices for terminating on 2G vs 3G networks, relating to BT & the various other UK network operators. My reading of it is that BT has to pay retrospectively a 'reasonable' blended termination fee (higher than 2G) that incorporates the supposed higher costs of 3G voice termination. That was actually determined in Ofcom's document on interconnect earlier this year, but the dispute relates to an earlier period.

...but I'm trying to work out if BT's being really really clever on this..... despite its protestations about 2G vs 3G termination costs, it's actually in BT's longterm interest to have termination fees to mobile numbers being cost-variant across different technologies. This then gives it scope to argue the right to pay less for any future calls to mobile numbers that terminate on a cheaper network infrastructure - say over WiFi, or via a femtocell, via fixed VoIP, or to a voicemail server.

2G - WiMAX dualmode

Had an interesting chat with a company called Comsys this afternoon. It makes baseband chips for mobile phones. It's working hard on the notion of a different style of dual-mode that I hadn't really given much thought to up until now - combining wide-coverage GPRS/EDGE with more localised WiMAX for high capacity in urban areas.

I can sort of see the argument - especially for 2G operators & MVNOs that don't have existing UMTS spectrum or built-out networks, and think that 802.16e might be cheaper or easier to deploy. Conversely, it may be that such devices would enable WiMAX startup operators to start off with lower capex if they concentrated on build-out in dense areas, and cut an MVNO deal for occasional rural use.

One problem might be indoor coverage, however - I can't see 2.5GHz or 3.5GHz WiMAX having great penetration in-building, which may mean WiFi is needed as well. Another thorny question is around authentication - although Comsys is positioning WiMAX as "a cellular-type technology" I haven't seen much enthusiasm for using SIMs with it thus far, although I guess that a UMA or VCC approach might work.

Nevertheless, an interesting option & worth keeping an eye on.

Will the WiFi Blackberry support multiple philosophies?

Looks like the much-rumoured WiFi/cellular BlackBerry is finally on its way. An outstanding question is whether the WiFi function will be accessible for carrier services (eg UMA, VCC), or end-user local connectivity (to a corporate WLAN or public hotspot) - or both.

I'll take a punt that the underlying platform will support both - although possibly not in all operator-specific variants.

I suspect that T-Mobile US may have come up with a superficially compelling reason for a UMA variant for use at hotspots (& maybe employees' homes), although it's not likely to be much use when the device is inside a corporate WLAN & firewall. UMA isn't designed to work with complex switched WiFi networks (Cisco, Aruba, Trapeze et al). There have been various noises to make some of these UMA-friendly, but they don't appear to have got anywhere substantive. One of the problems is that UMA needs to make an outbound VPN connection to the operator's UNC - not something that the average enterprise security manager would be too happy about, unless a separate partitioned domain could be implemented on the wireless network.

Conversely, most of RIM's other operator customers aren't using UMA, and so presumably won't want to be spending money for lumps of complex software in the stack that will go unused. I suppose it's possible that they could ship with the UMA software 'dormant', though - especially if the per-device royalty was only payable on phones which were actually activated. Whether it'll have some form of VCC/pre-VCC client is another matter - I suspect we might have to wait for dual-mode BlackBerry V2.0 for that.

On the other side of the coin, I imagine that RIM has been keenly aware of the drive for SIP-based PBX-centric dual-mode devices - and conscious of Nokia's E-series and various Windows devices' incumbency there. The lure of unified comms, VoWLAN and possible tighter relationships with Cisco, Avaya, Divitas, Siemens, Varaha and assorted others must be pretty potent. I'd imagine RIM doesn't want to miss out on an emerging market for converged corporate voice/data devices.

But that opportunity comes with a sting its tail - although some of the fixed/mobile hybrid carriers are moving towards managed dual-mode IP-PBX implementations (eg BT Corporate Fusion), there is definitely a strong move towards enterprises buying 'vanilla' WiFi handsets through alternative channels, rather than operator-customised ones.

So.... could the dual-mode BlackBerry make an appearance through non-operator channels? Perhaps sold through a systems integrator, with the enterprise sourcing SIMs and voice/data airtime separately? It's got to be a tricky decision for RIM, given its strong carrier partnerships. But sooner or later, they have to deal with the undeniable fact that some enterprises will want to source all their own mobility hardware (including mobile email servers), and just pick one or more operators as a cellular bit-pipe.

Words fail me

I don't like to take potshots at my competitors, but this quite frankly beggars belief.

Now, I should caveat my judgement in that I don't know the assumptions, definitions etc in the full report & model, but even so, this is so far beyond the "smell test" I don't know where to begin.

But lets start with:

  • Enterprise - UMA initiatives are going nowhere
  • Prepay (seen any FMC models suitable for 70% of the world's subscribers? I haven't)
  • Inapplicability to CDMA/WiFi (ie about 20% of users)
  • Limited base of broadband homes with WiFi
  • Refarming 900MHz to give better indoor coverage
  • Falling cellular prices making homezone pricing irrelevant
  • Femtocells
  • SIP & VCC standardisation coming with 3GPP R6 and R7
  • Lack of WiFi penetration into handsets

Some of this doesn't apply if the stats also include non-dual mode devices using UMA (eg femtos), but it still looks out by getting on for an order of magnitude. I haven't redone my full model & forecasts for a while, but if I had to take a punt, I'd be being generous if I said 10 million subs by 2012.

As always, let me know if you'd like a disruptive second opinion.

Femto conference thoughts

I'n at the Avren Femtocell conference near Heathrow today - I'm speaking on a panel later about femtos vs. home-cells vs. dual-mode. It's a very well-attended event, with a decent representation of operators as well as a broad range of vendors.

I'll try & update this post through the event, although I'm not sure if I'll be here tomorrow & Thursday.

One particularly interesting development has been the instigation of the Femto Forum and I've already heard a lot of discussion around standards.

But... I'm becoming increasingly skeptical of the near-term opportunity, especially in mature broadband markets. Some general areas of concern:

  • rapidly-growing installed base of non-femto home gateways & settop boxes. In the real world, most early femtos will need to be "daisy-chained" off the back via an ethernet port, adding to installation and configuration headaches
  • lots of unrealistic expectations about "single operator households" supposedly where one provider supposedly offers a whole family a bundle of mobile phones, broadband & maybe IPTV and so forth. Maybe in utopia, or in a country which is a mobile/broadband greenfield, but again in the real world, people have multiple phones, households have members with different requirements, longterm contracts are always out of phase, and so on. How do you manage a house with 2+ femtos?
  • No mention thus far about how to optimise a femto offering for prepay subscribers
  • By the time femtos are massmarket, 900MHz UMTS will have solved many of the macro coverage problems
  • Ideally, handsets will be femto-optimised to enable them to use the indoor coverage "well", ie for data-related applications like content backup, TV watching etc
  • Unclear what the working life of a femto is expected to be - and how that fits with the blistering pace of development of the rest of the IP/IT/WiFi/broadband part of the system
  • Assumption that the femto voice-stream will get priority on the broadband connection. Who decides QoS prioritisation vs. home access to enterprise VPNs, streamed TV, home security or various other 'important' uses of the pipe?
  • For mobile-only operators without their own broadband (or close ISP partnerships), the femto model assumes Net Neutrality, which has the potential to raise accusations of hypocrisy. ISPs will investigate ways to charge 'parasitic' mobile operators who want to use 'their pipes' for free.

None of these are unfixable problems. I still like the underlying concept of femtos. But these problems will take time & keep the new Forum occupied. I haven't done my own forecasts yet, but my gut feel tells me that one of my peer's much-ballyhooed 5-year forecast of 36m units is over-optimistic.

Oh, OK, my pre-iPhone opinion too....

Seeing as every other mobile analyst & blogger has been pontificating about the iPhone, I might as well add my opinion as well.

1) Yes, it's very cool
2) Apple seems to have done a great job getting AT&T to agree to its own private activation & application strategy
3) Apple fans will love obviously it
4) Fashionistas will love it for about 3.5 weeks and then move onto the next shiny thing
5) Nearly everyone who buys one will probably use a second device, probably a "boringphone"
6) The US mobile market may be galvanised by Apple's "game-changing" approach
7) SMS will be a pain with the touchscreen
8) Success in Europe & Asia is dependent on iPhone v2 and v3
9) If it launches in current form in Europe, it stacks up badly feature-for-feature against its high-end peers (camera, no 3G or GPS etc)
10) Distribution in Europe is still up for grabs. Voda might make sense, given it's professed desire for better PC/mobile integration - the iPhone looks classleading in that respect
11) It damn expensive, especially on a 2-year (!) contract
12) Enterprise users - only if bought for personal use & then used for work. Forget about corporate email support and especially VoWLAN / FMC for at least 12 months
13) OK OK OK I was wrong when I guess that Apple wouldn't put music in it. I'd thought they'd want to sell you a phone AND an musicplayer, but they've succumbed to the convergence hype.... (wrong move Steve - the future's about lots of devices & multiplicity)


Bottom line: I'd say it'll be a winner in the US, do OK in Europe - but that I'm waiting for Apple's 2nd move to see if it's actually got a real strategy rather than just a pretty product.

And me? I wouldn't swap my main, personal, SonyEricsson K800i for an iPhone as I like the 3MP camera with a flash, and the ultra-quick UI. But I would use it as my 2nd/3rd/phone if it offered a better email/Internet experience (and maybe 'content' although personally I think video isn't of use to me)

OMTP handset VoIP settings requirements - pretty sensible

The OMTP have issued their requirements document for VoIP settings on subsidised mobile phones. I talked through it the other day with them - in general, it seems to make a good amount of sense.

In general, I have sympathy with the notion that if a phone is subsidised, then within reason the company offering the subsidy has some authority to tell the user how they can use it. In a truly competitive market, the user should be able to choose between various subsidised-but restricted combinations, or standalone unsubsidised-but-flexible ones.

The general thrust of the OMTP's recommendations is around those phones which are (a) subsidised, and (b) come with a pre-installed 'native' VoIP client.

Basically, if the phone comes with native VoIP, it should be able to have the operator's own VoIP service settings installed and 'locked'. It should also be unlockable after the contract expires, and critically, it should also be possible to load in 3rd party VoIP clients & settings, as long as they work alongside the operator's.

At present, 3rd-party VoIP vendors have 2 main options:

  • Use the native VoIP app (which is usually well-integrated with phonebook, messaging etc) and use it with new settings and a new "upper layer" (eg Truphone)
  • Ignore the native VoIP app and do everything from scratch (eg Fring)

With OMTP's stipulations, Option 1 becomes more difficult for a subsidised phone in-contract. That said, there's nothing to stop the handset vendor pre-loading two identical VoIP clients, or having one added on a memory card or downloadable when connected to a PC. Then VoIP#1 can have operator settings locked, but VoIP#2 could be open to all.

Other good stuff in the document:

  • Basically, the settings-lock is similar to SIM-locking. It's intended to combat the risk of 100 operators locking phones in 100 different ways. Instead the idea is that they're all locked in a consistent fashion - which helps everyone. With this, there's absolutely no question of locking down the SIP stack outright, for instance.
  • An enterprise should (in theory) be able to install its own VoIP applications and have them locked - essentially acting like an operator. So if Acme Inc goes out and installs dual-mode VoWLAN clients from Cisco, Avaya, Divitas or whoever, then John the Salesman shouldn't be able to muck around with the settings if he wants to play around with Skype or whatever on his company phone. Mind you, exactly how this is done is another matter - I was with Cisco's VoIP guys yesterday, and nobody had bothered to tell them that this type of option was going to be enabled, or how it might be achieved....

Netgear + Ubiquisys : necessary but not sufficient for femtocells

Good to see one of the first concrete signs of integrating femtocells with broadband routers. There will be some markets in which the mobile operators also have fixed/broadband sister companies or partners, so they can hope to offer an integrated device in the future.

However.... I really don't buy the idea of a single service provider for multi-person households for broadband+mobile. In a family you may find that each family member is on a different contract phasing, so you can't migrate everyone to a single operator. One adult may have a company-provided phone. Little Johnny might want a specific handset on a particular MVNO. Any or all of the family members might have 2 or 3 separate mobile devices or service providers.

Add to this the legacy issues - most homes already have a broadband provider, quite possibly with either an integrated WiFi capability or separate AP. Not many people churn broadband provider - it's particularly a pain if you've got ISP-named email accounts - or, in the future, IPTV or other services locking consumers in. Not many people are keen on throwing away their existing WiFi box for fear of having to set up all their device configurations anew.

Bottom line is that "one box" households are implausible, especially for the more valuable customer segments. Until there's a good way to link up, configure & manage multiple APs, routers, femtocells - as well as integrate them into single units - the market won't grow.

More specifically on the Netgear announcement - available for testing Q4 2007 for commercial deployment early 2008? Not a chance. Expect at least 9-12 months of large-scale testing, both technical (eg what happens if you have 1000 femtos in a square mile?), and commercial/user testing (price, packaging, setup, support etc). Probably add in another 12 months to optimise billing systems and handsets. Mid-2009 maybe, assuming everything's going well.

Like the representatives of Netgear & Ubiquisys, I too will also be speaking at the International Conference on Home Access Points and Femtocells, taking place in London from July 3-5

T-Mobile launches UMA US-wide... and another launch as well

I see that T-Mo has finally launched its UMA service nationwide in the US, just 17 months after announcing it. It has a huge range of 2 fairly basic [VGA camera?!] phones from Nokia & Samsung, although from one of the comments on Engadget suggests that other phones [Curve? and Pearl 2 - presumably a BlackBerry] are rumoured to be on the way.

Interestingly there's also a comment that Cincinnati Bell has also launched UMA, which appears indeed to be true - although the poster is rather less than effusive.

WiFi in the Baltics - showing how it's done properly

A few days ago Martin Geddes wrote this piece about his experience of WiFi in Lithuania's capital Vilnius.

By coincidence, I'm currently sitting in a cafe in its neighbouring capital of Riga in Latvia. I ordered a very good cup of coffee for about £1.70, along with a one-hour WiFi prepaid card from Lattelecom for £1. The waitress, who knew exactly what WiFi was, brought the card to my table and added it to my bill. Username & password are a user-friendly 6 characters long, the login process equally simple.

My hotel last night also had a Lattelecom hotspot covering both public areas & rooms. Again, a very simple, memorable, hotel-wide login, with the cost covered by my room price.

I'll guess that in both cases, the cafe & hotel use Lattelecom's broadband services, and get provided with WiFi by default.

This is how public WiFi should be done. Take note, price-gougers at Swisscom Eurospot & peers.

AT&T video sharing. Not new, and what's the point anyway?

There have been various IMS/almost-IMS video sharing trials and deployments over the past 18 months. Nokia's one with CSL in Hong Kong was an early example.

So quite why AT&T thinks it's somehow special is beyond me. Almost as far beyond me as why anyone else thinks that video sharing (or "see what I see" as some wince-inducing marketing people put it) satisfies any consumer needs whatsoever.

Leaving aside the fact that it doesn't work across networks, or on any but a handul of phones, or that people who are walking or driving can't watch inbound video, let's think about the practicalities.

1) I see something cool/interesting.

2) I call you up "Hey, I'm watching something cool/interesting, check this out!"

2b) 97% of the time you're on the wrong network, wrong phone, out of coverage or too busy to watch video

3) Miraculously, you watch what I can see, in realtime, over the network. Awesome!

4) I meet up with 10 other friends in the pub that evening "Hey, I saw something really cool/interesting today!" .... "Wow dude, did you record it?".... "Errrr. No. I expensively sent it to Eric in realtime, so I can't show it to you guys. Or upload it to Youtube. Or email it to my aunt. Damn".

And yes, I know the hypothetical scenarios of a business traveller being called by their spouse to see what their little child is up to. Given point (2b) above, this will only work on a call at a pre-scheduled time. When you might as well stick the little blighter in front of a PC & webcam and do it for free via Yahoo or Skype....

It's a solution looking for a problem.

Thanks, Jonny, much appreciated

I'm feeling a little self-congratulatory this morning, having been ranked #11 in Technobabble 2.0's analyst bloggers table, (and, it seems, the highest-placed wireless analyst) courtesy of Jonny Bentwood at Edelman.

Thinking about it, though, I feel a little bit uneasy too, as I don't really identify myself as a "blogger" as such. I write here for a few reasons - it gives me a chance to put an analytical stake in the ground on topics I'm opinionated about, but that I won't get a chance to write up in a full report. I often find writing posts a good way to crystallise my thoughts on various topics. And quite frankly it generates a significant amount of business from both new and existing clients, which means I can justify the time quite easily. Plus I often learn a lot from the comments on my posts.

But I eschew much of the trendier blogging tools and "furniture". I can't be bothered with things like Digg or del.icio.us or tag clouds, I'm using a boring off-the-shelf Blogger template, and I'm terrible about updating basic things like external links. I've never looked at the Technorati site until today, so I don't even know what the significance of Jonny's use of it in his ranking is. I'm not even that bothered about publicising the blog to widely - my perception is that it has a smallish but self-selected group of "the right people" reading it.

So maybe I should use this opportunity to ask for some feedback: does anyone actually care that about all those cool up-to-the-minute blogosphere features? Could I make the blog easier to use? Or is it just "all about the content" and it's fine the way it is?

Truphone and T-Mobile Interconnect - I see the argument, but they are both on thin ice here

The ongoing spat between T-Mobile and Truphone about interconnecting between VoIP and circuit-switched mobile is an interesting one. (See Truphone's side of the argument here)

In a nutshell -Truphone has managed to persuade the UK regulator to issue it with mobile numbers (07xxx) although it doesn't own/operate a cellular network. It argues that the increasing practicality & ubiquity of VoWLAN enables it to offer a "mobile telephony" service without a conventional mobile network.

The problem is that while this decision gives Truphone some unarguably reasonable things (a mobile number - ie the primary one that people tend to save in address books, and use for things like SMS), it also comes with some less-reasonable elements. In particular, as termination fees for calls to mobile phones are supposedly cost-based, it's unreasonable to expect the inbound operator to receive the same money for terminating on (cheaper) WiFi than on a cellular network. Thus T-Mobile resents paying the same to terminate calls on a Truphone number as it does on Vodafone or Orange numbers. It appears to be using a recent Ofcom ruling on mobile interconnect rates that contains the phrase "for connecting calls on their mobile networks".

I've written before about the likely complexities of numbering & interconnect in an FMC world. Given that there are plenty of VoWLAN providers that operate software on handsets, I'm not convinced that there should be any difference between those that manage to argue their way to an 07xxx number range, versus the others.

So at one level I can sort of see T-Mobile's point - and I can also see Truphone's point that T-Mo appears to be acting in a unilateral, heavy-handed fashion. And so this wouldn't be quite so much of a problem if it was just that Truphone didn't get full-whack interconnect fees for VoWLAN termination, but just the measly 0.21p per minute that T-Mo has reportedly offered. The real problem is that in some cases, Truphone incurs a lot more costs by forwarding the call to the user's "underlying" GSM number on the same phone when it's out of WiFi coverage. This is expensive, and therefore all forwarded calls cost Truphone much more than it gets out of T-Mo to begin with (" even when Truphone's costs are 9p per minute to terminate the call"). Mind you - that's actually terminating the call on someone else's mobile network, not Truphone's , so it's still not cut & dried.

But I reckon T-Mobile is in serious danger of painting itself into a corner on this, unless it is hoping to prompt a much wider review of FMC and wVoIP interconnect.

In order not to appear hypocritical, T-Mobile will also have to refuse to pay full-rate interconnect fees for BT Fusion or Orange Unik (or, er, T-Mobile US' UMA service) when they're in WiFi coverage, as that's also much cheaper to complete calls. Or to any of the mobile operators looking to extend their brand & number range out to PC-based VoIP clients.

And in response, any fixed operator would be well within their rights to refuse to pay mobile termination fees to T-Mobile for the privilege of completing those calls which divert to a voicemail server (again, cheap), rather than connecting to an actual end user over the cellular network.

And T-Mobile is also therefore implicitly staking a claim to only 0.21p per minute interconnect, when it transitions its cellular network to all-IP LTE, presumably around 2011. That will have to use VoIP, as circuit-switched telephony isn't supported. Put that date in your diaries, interconnect managers at Vodafone, Orange, O2 & 3 - as soon as it starts to support VoIPo3G, feel free to slash your payments. They've made their bed; let them lie in it.

Basically, T-Mobile's short-term hissy fit (although in some ways understandable) has long term ramifications. Up until now, everyone had operated on the unspoken principle of "mutually assured destruction" about the real complexities of interconnect and termination in an IP world. We had a standoff, with all players knowing that calling-party-pays, mobile vs fixed numbering, and VoIP interconnect were likely casualties of the fallout.

T-Mobile UK has just pressed the big red button withoiut thinking of the longer-term issues.
