Excellent! Is the mobile data network core provisioned for all of these 7Mbps subscribers? Likely not... Does the necessity for a massive investment in GGSN and the services LAN capacity have any bearing on the slow rollout of services? Maybe... <br /><br />High bandwidth femtocell users are why operators must consider femto aggregation architecture scalability, and consider breaking out Internet traffic before the GGSN and services LAN. Both will support high bandwidth users and improve data service performance, and both will improve operator data service margins.DanMcBnoreply@blogger.comtag:blogger.com,1999:blog-17500930.post-26725022350146019732009-10-12T09:34:19.409+01:002009-10-12T09:34:19.409+01:00The other option here is that the femto traffic co...The other option here is that the femto traffic could be zero-rated and not count towards the fixed-broadband cap. <br /><br />Not much of an issue in uncapped / high-capped markets like the US (eg 250GB on Comcast I think?) but in some markets it's as low as 10-20GB per month, so "paying double" for 2GB of 3G traffic being backhauled is a significant issue.Dean Bubleyhttps://www.blogger.com/profile/05719150957239368264noreply@blogger.comtag:blogger.com,1999:blog-17500930.post-86443561043006152282009-10-12T09:32:11.585+01:002009-10-12T09:32:11.585+01:00Ah, but by the time LTE finally rolls out you'...Ah, but by the time LTE finally rolls out you'll have FTTH capable of supporting symmetric Gigabit Ethernet.... but I bet that even then, some people will still go for the cheapest (or free, municipality-supplied) broadband package.<br /><br />More seriously, one of the largest issues for femtocells is that almost all the devices that really drive traffic also have WiFi, so ideally there need to be differentiators. Less interference & more range are possibilities, also femto-based services. But the scenario I suggest here actually makes mobile broadband look like a premium service compared to ADSL+WiFi and could potentially drive substitution of usage and/or revenues, while still benefiting from offload.Dean Bubleyhttps://www.blogger.com/profile/05719150957239368264noreply@blogger.comtag:blogger.com,1999:blog-17500930.post-58368691616620081642009-10-12T09:23:46.178+01:002009-10-12T09:23:46.178+01:00An then the operator upgrades his macro net to 21 ...An then the operator upgrades his macro net to 21 Mbps (and end of this year to 42 Mbps, next year to 84 Mbps and later to 168 Mbps and LTE). Should the operator swap my femto every year free of charge and upgrade my ADSL to follow his macro speed...? Or will the user leave his house every time he wants the best performance?Anonymousnoreply@blogger.com
