| Re: Then they need to upgrade links from cell towers to backbone 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 | Re: Then they need to upgrade links from cell towers to backbone 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. | |
