Swedish telecom equipment maker Ericsson (s ERIC) and Australian phone company Telstra today announced the launch of an HSPA Evolution-based wireless broadband network that has peak speeds of up to 21 Mbps. In the U.S., AT&T (s t) is playing around with this evolutionary broadband technology as part of its planned wireless broadband upgrades. HSPA-Evolution uses MIMO and other such technologies and is able to deliver better battery life and better wake-from-idle time. Sierra Wireless (s swir) is making USB modems for this new network speed. Ericsson has a lot of information on HSPA Evolution and Nokia Siemens Networks (s nok) has a good white paper that covers the basics.
