...successfully completed TD/FDD LTE live handover testing with Rohde & Schwarz, a leading global manufacturer of wireless communications and EMC test and measurement equipment. The test, which employed Altair’s FourGee™ chipset in an end-user device, successfully enabled seamless communication between different LTE modes, achieving an uninterrupted and continuous data session with low handover latency from a 20MHz TD-LTE channel and a 10MHz FDD channel and back. The two companies are presenting a joint demo of their handover capabilities at the Global TD-LTE Initiative (GTI) Asia Conference on June 18-20th in China.

Altair is the first chipset manufacturer to achieve live TD/FDD LTE handover in commercially available devices. By allowing the two LTE duplex modes to operate interchangeably on the same device, as well as enabling global LTE roaming, this achievement has significant market implications. Altair’s FourGee™ LTE chipset is one of the only commercial solutions supporting both FDD LTE and TD-LTE. The chipset supports all 3GPP Release 9 bands and is deployed for commercial use in numerous LTE markets around the world.
