Most areas in the U.S. would have felt the cake LTE from Verizon, even though the signal coverage might not actually cover all corners as promised. Verizon's 4G users also been treated to the device to support that super-fast network, both the modem and the smartphone and there are a myriad of smartphones also Mifi are still waiting to be thrown into the market. Looks more and more serious.
No doubt, Verizon continues to expand its coverage area from time to time, and hopefully their 4G LTE services will cover throughout the U.S. in late 2011. According to previous records, there are already 39 and then 49 areas have been in the "radiation" of LTE 4G network until the end of 2010, and David Small, CTO of VZW promising total to 147 cities by the end of 2011.
