Re: Cmon DTV You are off a bit about how cellular technology works. They can't use 1000 ft towers to service large areas. The cell would be over saturated (not enough spectrum and bandwidth to go around) and many people would just end up with system busy messages. In urban areas they will actually need the same amount but then have to detune them. The new problem will become pilot pollution because the 700 carries a little bit farther than 850. It isn't much but enough that current spacing is a bit close but if they skipped every other cell the signal would carry that far. The issue is also transmit power of the tower and that of the mobile device. TV stations were broadcasting in many thousands of watts while cell towers and phones are limited to a very low wattage. To get the speed out of 4G the same towers are going to be used for the most part and the limiting aspect will be how much backhaul those companies can get in place. |
