Verizon has announced that it is on track to roll out their new 4G LTE service using the 700 MHz band that it acquired in the recent FCC auction. Targeted first towards USB air cards for laptop customers, the service will be extended to cell phones and other mobile devices with embedded LTE eventually. Testing in Boston and Seattle should conclude in the next couple of months and commercial deployments should follow soon thereafter. "Lynch said getting voice to work over LTE has been particularly challenging. But that challenge is getting resolved as Verizon and other members of the GSMA announced Monday they are supporting a standard that uses IMS technology to deliver voice services over LTE. Still, more work needs to be done. Until a solution is complete, Verizon will use its CDMA network to provide voice services. And the LTE network will be used for data. Eventually, when voice over LTE becomes a reality, Verizon will use that technology. Verizon will also have to integrate EV-DO into its LTE offering to ensure that customers can switch to the 3G EV-DO network when the 4G LTE network is not available. Even though Verizon is being aggressive in building its network, it won't happen overnight."
