"We have ALREADY agreed that this TV-related LTE network sill be 2-way, yes? So we have ALREADY agreed that the 84 MHz requirement of the IEEE article was bogus (it would be that for just one cell)." 

Okay, this might require clarification.
Good, since I already said broadcasters do not need to build a return path since the Telco data networks will provide this.
IF the TV LTE network is supposed to be capable of broadcasting all TV channels in a market, AND it also has to be a 2-way cell network, THEN each cell's channel will have to be 84 MHz wide (by their numbers) AND adjacent cells cannot reuse the same frequencies. IOW, this ain't just another SFN. It's a cellular network.,
The Feds are trying to recover about 120 MHz of spectrum from the broadcasters, leaving them with about 240, although a big chunk of this is VHF, which may not be useful for LTE. It is likely that there will be room for two Broadcast LTE bands in the remaining UHF spectrum. 

Perhaps existing ATSC can remain in the VHF band?

Mark Aitken, can you comment on this?

Craig
