Sprint Nextel Corp., the third-largest U.S. wireless provider, on Tuesday said it made tens of thousands of capacity upgrades over the last year, reflecting a doubling of its capital investment over 2010.
For Sprint's customers, the network improvements mean faster data speeds, enhanced signal strength and fewer dropped calls, according to the company, which served 53.5 million customers as of Sept. 30.
Sprint, which offers high-speed mobile services using WiMAX technology, also said it's on track to offer 4G LTE devices by the middle of next year; and the company anticipates offering further details in connection with the timing of LTE markets and devices in early 2012.
Sprint's bigger competitors, AT&T Inc. and Verizon Wireless, already have begun rolling out 4G wireless services based on LTE, or Long Term Evolution, technology. The LTE network at market leader Verizon Wireless covers about 200 million Americans in 190 markets. AT&T's network has been activated in 15 markets and the wireless giant was in the process of activating the network in New York City and other markets this month.
