"By the end of the year, most of our markets will be LTE-ready with 5x5 spectrum," Linquist said.
MetroPCS will launch 6 to 7 LTE handsets by year-end.
The company also reported that it now has 700,000 LTE subscribers, representing about 8 percent of its total base. That's up from 500,000 subscribers at the end of the first quarter.
Interestingly, MetroPCS, which has said it will offer Voice over LTE this year, also said it would launch a Rich Communications Services platform that would enable its move to IMS and allow the company to offer advanced services such as letting customers make calls and send video simultaneously.
Company executives also talked about MetroPCS' plans to refarm its existing 3G spectrum for LTE and continue to search for more spectrum opportunities. Regarding Clearwire's (NASDAQ:CLWR) 2.5 GHz spectrum, MetroPCS executives said that the 2.5 GHZ spectrum is useful, particularly in areas where a dense network is necessary. But they also said that the spectrum was an "expensive option" and noted that Clearwire's plan to build a TD-LTE network--scheduled to launch in June of next year--may have "time to market" issues.
