"Verizon now goes head-to-head with Clearwire and its main MVNO, Sprint, in offering mobile broadband services in many metro areas. Last week Clearwire crossed the 100m POPs mark when it turned on WiMAX services in some large markets such as Los Angeles and Miami. AT&T, which will start rolling out LTE towards the end of next year, and T-Mobile, which has no 4G spectrum or partnership as yet, will be playing catch-up."
