What has the TD-LTE Industry been doing while Verizon and AT&T have dominated the LTE discussions with their FDD-LTE deployments? See the link below to see the industry briefing provided by the Global TD-LTE Initiative (GTI) organization. On Wednesday's earnings call, Clearwire aluded to being a member of GTI along with China Mobile and Vodofone. This briefing details testing of tunable MIMO antennas and the availability of multimode multiband user devices.
TD-LTE Industry Briefing - May 2011
A couple of other interesting points from the report. AT&T was a presenter on the multimode multiband LTE user devices. This makes sense since the report makes it clear that the international focus on TD-LTE is in the 2.3GHz and 2.5GHz band. AT&T is a significant holder of the US WCS spectrum. The WCS spectrum consists of 3 paired 5MHz channels that bookend the DARS (Digital Audio Radio Service). If a carrier controlled all 3 pairs channels, they would be capable of having a two carrier system using 15MHz channels.
