So Bert continues to challenge the notion that it us possible for existing 
broadcasters to migrate to a new Broadcast LTE standard, claiming that the 
telcos won't allow it, and that it would be much more expensive to implement 
than a new standard that uses the legacy market based "big stick" approach.

I have suggested that it will not be difficult for broadcasters to lease space 
on existing cell towers, and to use existing broadcast tower infrastructure 
where possible.
I have also suggested that the telcos have a number of barriers that are higher 
than those that broadcasters face, especially the cost of spectrum and the cost 
to implement a subscription or ad supported business model for content.

So I decided to do a bit of research to determine what others are saying about 
this subject. I am appending a list of sites with interesting articles on the 
subject. What I learned from these documents is that the cost for both the 
transmission equipment and for leasing space on towers has declined 
substantially, improving the economics for Broadcast LTE.

Here is the relevant URL:


I also learned that both Ericsson and Qualcomm appear to be targeting the 
telcos with their proposals, and that AT&T is starting to build out a Broadcast 
LTE system in the 700 MHz spectrum they purchased from Qualcomm, after they 
shut down FloTV.




It is unclear exactly what AT&T plans to do with the system, but the papers 
provide a wealth of information about potential services, including many that 
have nothing to do with video streaming.

I would add, that there is nothing to prevent both broadcasters and the telcos 
from implementing Broadcast LTE, using similar, or completely different 
business models. Broadcasters could continue offering ad supported FOTA 
services, while the telcos could generate revenues from subscription fees or 
payments from companies using the network to distribute content to devices 
owned by their customers. 

For example, Broadcast LTE could be used to download content to subscribers 
during off peak hours, to download software updates to mobile devices, or to 
download content to point of sale devices. One factor I had not considered is 
the cost saving to the telcos by offloading multiple unicast sessions for the 
same data to a single multicast to these devices; this frees up bandwidth for 
other services/more unicast sessions.

Enjoy the reading assignment, and let's get more folks into this discussion!
