|  Then they need to upgrade links from cell towers to backbone
If they claim these high speeds from the phone to the cell tower, then they better have a very aggressive upgrade of the links from the cell tower to the backbones. In downtown areas that may not be a problem, but as you get in to suburban and rural areas, most cell towers only handle T1 speeds to the backbone. Having 20 mbps from phone to tower means nothing if the rest of the infrastructure is not also upgraded.

| By 2009 the majority of towers will be OFF of copper T1's. Using a Charles Industries Wescom repeater, the same one used for copper T1 extensions, they're placing a Pulsecom card that takes four (of 28) slots. It condenses those spans into a single fiber. This fiber is then shot to the towers.
This is done for two reasons: higher speeds and reliability. After the tower is cut to FTTCS its rare that a tech is dispatched out there again.
I'm not saying this is going to enable the site to have 50+ 20MB customers, but it's where they're starting. |

Valencia, CA | In Uverse cities, this shouldn't be an issue... there's fiber to nodes all over the place. A short run between a Uverse node and a cell site wouldn't be difficult.

All that does is make the last mile on fiber but still has only 4 T-1's (6 Mb/s) feeding it. Here in Connecticut and other locations as far as I know, we are placing fiber to either Nortel or Fujitsu equipment right at the cell site that can provide DS3's, Ethernet or OC3's which will truly support 20 Mb/s wireless. So many of the sites will be capable of these speeds all the way to the web, not just the tower. |
