Ericsson shows 56Mbps HSPA
Ericsson announced on Tuesday that it will demonstrate HSPA data speeds as fast as 56Mbps at the CTIA Wireless convention, which kicks off on Wednesday. The speeds should double those of 28Mbps-capable networks launching in North America, Germany and Italy. At Mobile World Congress in February, Ericsson successfully demonstrated speeds in a similar network operating at a peak of 42Mbps. The next step in the evolution of the HSPA technology, dubbed HSPA+, involves the use of a combination of multiple-input-multiple-output (MIMO) and multi-carrier HSPA technology.

Qualcomm Multi-Mode 4G
Qualcomm today said it would be the first company to produce chipsets capable of supporting multiple 4G Internet standards. Three of its chipsets will now not only support the Long Term Evolution (LTE) standard that will be used many larger world carriers but also competing and bridging standards: the top two chipsets, the MDM9600 and MDM 9800, will support the upcoming EVDO Rev. B and Ultra-Mobile Broadband (UMB) standards for CDMA networks even as they support LTE networks once they appear. Each will be powerful enough to handle downloads as quick as 50Mbps and uploads as fast as 25Mbps, Qualcomm says.

ATT 3G Expansion in 2008
AT&T today said it would rapidly expand its third-generation (3G) cellular data network over the course of 2008, greatly improving coverage of the relatively fledgling service. The carrier intends to introduce its HSPA-based Internet access to 80 new cities throughout the year to include a total of 350 areas. Many if not all of these current and future areas will be upgraded to use the faster HSUPA (High Speed Upload Packet Access) format, AT&T adds. Practical speeds for these networks are estimated to range between 600Kbps and 1.4Mbps with downloads and between 500Kbps and 800Kbps for uploads, enabling video uploads as well as more two-way Internet features.
