That's what makes it expensive, Craig. The fact that in order to make effective use of the available spectrum, you have to deploy many small cells. There's a lot of infrastructure involved, including of course the backhaul networks, even for wireless. > So here is your big chance Bert.

Something as high up in frequency as possible, to give you plenty of channel capacity, directivity, short range, easy frequency reuse. There is a lot of available spectrum up where these new home services should be. I'm talking up in the 20, 30 or more GHz. > Let's assume the telcos buy the spectrum that broadcasters vacate > in the next auction.

It's too low in frequency, so it wants to propagate too far for effective frequency reuse (i.e. you can expect co-channel interference), and it is challenged for channel capacity too. I always thought this was oversold by ex-Chairman Genachowski, and I'm seeing perhaps less emphasis on this from Wheeler. > Nationwide is a bit of an overstatement. > They started in the major markets, where they owned the stations. > They grew into smaller markets using affiliates. > . . . Different discussion. The coverage of the individual TV networks was always intended to be nationwide, never limited by any concern about "having more voices heard." If anything, that concern would be allayed by urging more TV networks to be built. If there was any limitation in coverage, it was merely a problem with installing the broadcast infrastructure. > Limiting ownership assured a diversity of voices. The intent has > always been to keep the networks from dominating "the conversation." That almost makes sense. Although again, in any given location, it is availability of multiple networks that solve that problem, more so than whether these same networks are available elsewhere or not. > Cable changed everything; with satellite back haul it became easy > to create national networks. I think you really missed it, Craig. First of all, satellite backhaul also works for OTA delivery. Secondly, the only thing cable changed was number of available nationwide networks, more than availability of existing TV networks nationwide. You had all manner of OTA translators and CATV systems, decades before cable and DBS MVPDs. MOST OF ALL, what MVPDs do is they put a lie to this national caps pretense. They expose national caps as being a farce, which for some reason only need apply to delivery of ABC/NBC/CBS/Fox. Hey, what about HBO? What about ESPN? What about HGTV? (And on and on.) And when ex-Chairman Michael Powell explained this, look at all the platitudes he got back from our "leaders" in Congress, not to mention the trade scribes.
