Sierra 3G USB Modem Gets MIMO Treatment

Sierra wireless next week will be showcasing its new HSPA+ modem and the Mobile World Conference in Barcelona Spain. The 306/307 model USB modem promises triple the potential bandwidth of the highest speed currently to consumers. Looking at what's currently available from most US carriers this is actually 7 times faster! HSPA+, a multi antenna MIMO version of HSDPA, promises 21Mbps download and upload up to 5.7Mbps (compared to UMTS's max of 7.2Mbps / 2Mbps) once it's rolled out. Both will have no problem communicating on the old GPRS/EDGE/UMTS networks. Of the 2 models, the 306 is the tri-band (850/1900/2100 MHz) North American/Asia-Pacific UMTS model and the 307 is the dual band (900/2100 MHz) European UMTS band version. These should become available in Q2 this year provided the telcos evolve their networks to support them.

Unfortunately there are no current areas that are supporting the HSPA+ network in North America or Europe. Australia's Telstra and Hong Kong's PCCW are the only current carriers with some HSPA+ features enabled. AT&T does seem to be making inroads in that direction until LTE networks are ready. LTE promises 326Mbps down and 86Mbps up, but is still quite a few years off. This could get pushed out even further due to the financial problems the providers like Nortel are having lately.
