T-Mobile USA, Nokia Siemens Networks Working on 650 Mbps HSPA

Mobile service providers would be able to achieve peak data rates of more than 650 megabits per second using a proposed HSPA standard supported by T-Mobile USA and Nokia Siemens Networks.

"Long Term HSPA Evolution" would improve mobile broadband with speeds matching those promised by LTE Advanced. T-Mobile USA and Nokia Siemens Networks are driving the technology’s standardization aiming to make it available for commercial deployment by 2013.

The proposed standard would boost bandwidth by allowing use of multiple frequency bands, creating larger channels and hence faster access. The standard might give T-Mobile USA, for example, more opportunity to upgrade its existing HSPA+ network for faster speeds, without requiring a switch to LTE Advanced.

Still, T-Mobile USA might require more spectrum, some of which it might be able to reclaim from frequencies now used to support voice operations on its GSM ntworks.
