SaaS & UCaaS - aiming for Enterprise Eyeballs

I'm at Enterprise Connect in Orlando this week, talking to people about trends in business communications, notably UC, conferencing, cPaaS and contact centres. I'm curious to see the current real-world adoption of WebRTC, shifts around enterprise mobility/wireless, integration with VoLTE, and adjacent technologies such as SD-WAN, machine-learning and IoT integration.

One unexpected thing has become clear from Day 1: the enterprise market is following the consumer web insofar as every vendor and service provider wants to maximise share of users' attention, or "eyeballs".

While in the consumer world, this is all about advertising and data - spending hours on Facebook translates to more chances to see ads, as with TV - in the business world it's a bit different. 

Because software has license fees or XaaS subscription revenues, all the vendors want to create "platforms" in which customers' employees "spend their day", at least when they're in front of a PC or mobile device. More time potentially equates for higher per-seat fees, plus more chance for selling extra modules of software.

So a UC or UCaaS provider wants to be the hub for calls, chat, conferencing, collaboration, "enterprise social", customer interation, productivity and so forth. Cisco, Broadsoft, RingCentral, even Amazon with its new Chime app, all have pretensions to being where you spend hours a day "doing work". 

An office suite provider like Microsoft wants the same thing - you should be sending emails and doing presentations, and communicating from there. One speaker today described workers having different "jumping-off points" for setting up meetings or collaborating. One employee might have a Salesforce interaction as a trigger, others could be inside Slack or Outlook or a call-centre front-end (or various vertical-specific applications).

Obviously many jobs only have a few minutes a day in front of a screen or on a phone, but others (knowledge workers) involve hours. There's probably a big-data and machine-learning play emerging here as well, where increased eyeball-minutes can yield insights into worker productivity and process efficiency. Arguably Google scores extra points here too, if you're logged in and using Chrome for some of your work.

As far as I know there's no business-world equivalent of TV viewing-habits or web-browsing statistics. But there's certainly a rush for different vendors and XaaS providers to drive up their ratings. I expect we'll see a much broader focus on "enterprise eyeballs" through 2017 and beyond.

EDIT: A good point from a commenter on my LinkedIn, that other players here are workflow & ERP providers. A lot of people will "live" primarily in SAP, Oracle etc during their day - those could also be the hub for UC and collaboration as well. Also, for the consumer space, ComScore have just published research (link) on how people spend their "digital minutes" (ugh, horrible expression) - a business-user version would be fascinating.

No, 5G won't kill WiFi (or absorb it)

I've seen two things today that are trying to suggest that 5G (or even 4G) are going to cause problems for WiFi, or even "kill it".

Ignore them.

Firstly, this piece by Bloomberg (link) suggests that a combination of mobile operators' renewed flat-rate data plans, along with LTE-U, could render WiFi obsolete. It's one of the worst pieces of technology "journalism" I've read in ages.

Secondly a discussion on Twitter led to a 3GPP document about "New Services and Markets" from a year ago, which talks about "Mobile Broadband for Indoor Scenario" in section 5.5  (link). That seems to suggest that 4G/5G could replace office WiFi or even wired LANs.

Needless to say, both are total nonsense. There is a longstanding strain of thought among some "cellular fundamentalists" that WiFi is just a step away from being replaced by mobile operators' services. It is wishful thinking, verging on delusion. (It won't be subsumed as a mere secondary part of 5G, either - although that's a separate post).

While there are some corner-cases that might swing one way or the other, based on pricing and perhaps neutral-host cellular using LTE in unlicensed bands (perhaps in MuLTEfire guise rather than the anti-competitive LTE-U and LAA variants), those are rare exceptions.

In home, offices, and public spaces, there is essentially zero chance that owned WiFi or fixed ethernet are going to be replaced in large quantity, by 5G operators acting as LANaaS providers.

There are many reasons for this, but some of them are:
  • Billions of WiFi-only devices, from PCs and tablets, to TVs, printers and a broad array of consumer and industrial products.
  • Billions more WiFi-only devices in future (no, not everything will have a cellular module & eSIM - it's way more expensive and limiting - see my report link)
  • The ability for WiFi to operate easily in "service", "subscription", "amenity", "owned", "free", "local", "sponsored", "venue-provided", "ad-supported" and many other business models. Cellular connectivity - reliant on SIM or eSIM - generally enshrines "subscription" and a service model as the only option.
  • Ability of venue-owners to control and police WiFi network access (eg a cafe-owner or conference organiser can give the codes to their choice of user, under their conditions)
  • Use of WiFi Direct for P2P connectivity
  • Integration of WiFi in businesses with LAN and security systems
  • Preferential use of WiFi in-built to smartphone OS's and connection-management tools
  • Large % of people who are not using flat-rate mobile data plans, especially prepay users in most of the world
  • A broad view that WiFi is not only "free" but also *different* as it isn't owned / metered / tracked by a service providers. (We all recognise that amended Maslow Hierarchy of Needs picture, with WiFi scrawled as a tier beneath food & shelter)
  • Anonymity of most WiFi hotspots
  • Huge push of WiFi by cable, fixed-broadband and some WiFi-first MVNO providers, including to outdoor / metropolitan zones and being built-into 500 million or more home gateways around the world
  • Use of WiFi in public transport (buses, trains, planes) - even if backhauled by 4G and/or satellite, plus increasing use of WiFi hotspots in cars (again, linked via LTE to the network)
  • Poor penetration of cellular for deep-inbuilding use without DAS or small cell coverage, which is often impractical
  • Lower costs of infrastructure, especially given the heavy IPR load associated with 4G modems and base stations. 
  • Enterprise desire to use multiple connections for cloud/WAN access, eg via SD-WAN

I think the most risible line in the Bloomberg piece is this "Wi-Fi also helps fill in gaps in some office buildings and homes that have spotty cellphone coverage" - in many ways, it's the complete opposite of the way many users view the two technologies.

Every analysis I've seen has suggested that WiFi use is generally growing faster than cellular data consumption, and there is very little reason to expect it to change. In many ways, I'd expect WiFi - and also other unlicensed band technologies for LPWAN and IoT - to outstrip coming cellular use-cases, especially indoors but also for the wide area.

A less-virulent strain of the same bad idea is that 5G will absorb or subsume WiFi, as part of its amazing network-slicing / HetNet / integrated architecture. That's wrong too - although some cellular networks are fairly-well integrated with some WiFi, there is a very large universe that isn't, and for many of the same reasons won't be in the future either. The notion that 5G is some sort of magical wireless umbrella (or Borg) that will assimilate all others is just a "mobile industry establishment" fantasy and lobbying hook. 

One last thing I'd add - I'm seeing an increased amount of interest in the opposite to LTE-U and LAA - the idea of running WiFi in licensed bands, either with new forms of spectrum-sharing, or perhaps even with adventurous regulators looking at getting more usage out of existing spectrum. After all, if the technical work suggests that LTE-U doesn't compromise or interfere with WiFi, then the converse is true as well, especially at lower power in regions with no cellular coverage, or indoors.

Overall: Ignore any reports of WiFi's demise, or the ability of 4G/5G to replace it in the future. It's simply not going to happen, except in a couple of tiny overlaps on the big wireless Venn diagram. WiFi puts downward pricing pressure on cellular data - it's probably part of the reason for the return of flatrate data in the first place. It's also a prime example of "network diversity" which would be worthy of protection against creeping "network monoculture" even if it wasn't already guaranteed a healthy future.

If you're interested in the dynamics of 4G, 5G, WiFi, network diversity & spectrum policy, please get in touch with me. I advise operators, vendors, regulators & investors. I'll also be speaking at the WiFi Now conference in Washington DC in April 2017 (link).
