This is changing now with usage of iPhone, Blackberry and emerging Internet Mobile Devices already causing capacity issues for 3G networks. The solution is a quick upgrade to 4G and deployment of Femtocell/WiFi to improve capacity/coverage inside buildings. So unlike the 3G upgrade that was driven in many countries by government spectrum auctions, the 4G upgrade is driven by genuine user demand.

Not sure if Verizon will be using the 700 MHz exclusively for both up and down -- AT&T last fall said it would use some AWS spectrum for the up link, so some of this will be learned when more specifics are revealed. Probably a better point to note is that Verizon only has 20 MHz at 700 MHz, while Clearwire has around 90-100 MHz in most major markets at 2.5 GHz. @GM Thanks for the fix on UMB.

Verizon's alternatives included Qualcomm's UMB (Ultra Mobile Broadband), not UWB. 2. LTE is a Frequency Division Duplex (FDD) technology, so it will use two 5 MHz channels (one for the uplink, one for the downlink) for a total of 10 MHz (equivalent to the single TDD 10 MHz that Clearwire is deploying for WiMAX). The 700 MHz licenses include paired blocks that are structured for an FDD solution. Two notes:
