Which the cellcos WILL NOT permit the phones on their networks to use. So, what's the point? We have been over this in painful detail, Craig. A broadcaster's LTE overlay network would entail (a) lower spectral efficiency than ATSC or DVB-T2, and (b) a comparatively huge number of towers, just to keep their b/s/Hz halfway reasonable. So if broadcasters can somehow get the cellcos to use their RF distribution services, and I'm not sure how, that might be worthwhile. If not, and this is where I think we are now, then what's the point? If broadcasters need their OTA structure to be low cost and efficient, and won't have access to cellco phones anyway, they won't go with a scheme that requires 800 towers in a market like DC. I did the numbers for you in the past, using credible sources of information, so now you can google it up yourself. I think broadcasters might be better off outplaying Aereo at that online game, although possibly there's some potential agreement, which I can't imagine right now, with the cellcos. > IT is completely material. Without the rights to the most desirable > content there is no benefit to building the overlay network. Already discussed. First, the rights can be had by the cellcos, as Verizon proved already (even if customers were not so thrilled). Second, the owners of content have absolutely no reason to withhold those rights, *if* there's a middleman that they see as instrumental. Why would, say, Viacom, deliberately shut off the mobile market? That would be silly. If it's another credible revenue stream for them, they'll jump. > By the way, Verizon shut down Vcast because they could not sell > customers on ANOTHER subscription TV package: Yes, I had suspected as much. So, what does that tell you about the desirability, from the cellco point of view, of sending TV to phones, in a way that can make the cellcos any money? > Again this is completely material.

Secondly, why would a broadcaster care to go LTE to begin with, UNLESS he has some sort of assurances that cellcos will allow their phones to tune into the broadcaster frequencies? It's just a way of losing some more control, as far as the cellcos are concerned. > 1.

All 3G phones went to W-CDMA, and certainly could have been built to use the different frequency bands. Same goes with LTE. The TECHNICAL limitations are self-inflicted by the cellcos, not by the cell phone makers. > 2. Subscriptions and Sim cards.

Cellcos set it up this way on purpose, and I'm asking you, what would make them change their business model?
