Emergency alert system[edit]

It is very true that Barack Obama has backed the need for an emergency alert system that uses mobile operators for the broadcasting of alert messages. However, there is absolutely no grounds to believe that operators will use MBMS for this. For all what is likely they will just use plain old unicast delivery. Note that there are no commercial deployments of MBMS known, and there likely won't be for some time to come because operators don't see the need right now. The introduction of LTE Advanced may change this, but until then... Nageh (talk) 16:42, 11 June 2011 (UTC)[reply]

Absolutely. For this application, unicast is perfectly fast enough for all practical purposes. SMS's are very small, and networks very fast in comparison to their size. -- The Anome (talk) 12:46, 9 June 2013 (UTC)[reply]

How long time would it take to unicast an SMS to every US cell phone? Let's assume maximum 10000 cell phones in each cell, and in average at least 1 Mbps capacity per cell for SMS purposes. Then the radio network would deliver it in 15 seconds. The problem is the node and backbone network capacity. Mange01 (talk) 21:46, 9 June 2013 (UTC)[reply]

SMS based alerting would be fine but once operators start deploying MBMS over LTE then support for alerting message would be trival. In other words, alerting itself is not sufficient reason to deploy MBMS over LTE but once it is in place even why not? Recommend that we add alerting as an example use case but not be a primary motivation for deployment. Alistair9210 (talk) 08:33, 15 July 2013 (UTC)[reply]

CMB[edit]

Proposed that we delete the paragraph on CMB. No source is quoted and no recent references on web can be found. Alistair9210 (talk) 08:34, 15 July 2013 (UTC)[reply]

Go90[edit]

Does Verizon's Go90 service verifiably use eMBMS? Can a reference be provided? — Preceding unsigned comment added by Wilkus (talk • contribs) 16:32, 15 October 2015 (UTC)[reply]
