Sprint 4G LTE Coming To 5 Cities More July 15

(Reuters) - Sprint Nextel Corp Chief Executive Dan Hesse said he plans to kick off a high-speed wireless service in five U.S. cities on July 15, a move that could be crucial in its efforts to compete with bigger rivals Verizon Wireless and AT&T Inc.

Sprint, the No. 3 U.S. mobile service, is upgrading its network with the same Long Term Evolution (LTE) high-speed technology its rivals are adopting, but is about a year and a half behind Verizon Wireless and about 10 months behind AT&T.

Hesse said on Wednesday the service will start in Atlanta, Dallas, Houston, Kansas City and San Antonio, and that more market launches will be announced later in the year.

Sprint also said that by the end of 2013, it expects to have largely completed the build-out of its high-speed LTE nationwide network across the United States.

The service, which is expected to provide money-losing Sprint a roughly six-fold increase in data speeds, is part of a $7 billion project that includes upgrading one network and decommissioning another.

Sprint has also committed to buying $15.5 billion of iPhones from Apple Inc in the next few years.

Sprint has said it would launch LTE around mid-year, listing Atlanta, Baltimore, Dallas, Houston, Kansas City and San Antonio as the first cities to have its LTE service.

Sprint already sells multiple phones that support LTE in the hopes that customers would buy the devices in advance of the service launch.

Sprint shares have been hugely volatile since it gave details of its upgrade plans in October last year. The stock was down 0.3 percent to $3.13 at midday.
