This week at the 4G World 2011 in Chicago, IL, embedded IP communications software developer D2 Technologies announced partnership with leading LTE chipset suppliers, Altair Semiconductor and Sequans Communications, to create voice over LTE (VoLTE) solution. Embedding its converged 4G mobile communications software for VoLTE, called mCUE, in a standard powerful CPU, D2 Technologies has developed a reference design using LTE modem chipsets from Altair and Sequans, respectively. And has done some interoperability tests.
Doug Makishima, D2’s chief operating officer, said that the results of the interoperability tests will be revealed next month. In fact, using mCUE and its underlying vPort embedded IMS VoIP software platform, D2 successfully completed the VoLTE Interoperability Testing in Beijing, China and Dusseldorf, Germany, last month. It was organized by the MultiService Forum.
“Data services over LTE are already a commercial reality in many markets globally, and as a company striving for constant innovation, we found an excellent partner in D2 for introducing the next evolutionary step for LTE —voice, implemented over LTE,” stated Eran Eshed, Co-Founder and VP of Marketing and Business Development of Altair. ”
Altair’s LTE chipset used in this VoLTE solution is FourGee-3100/6200. It supports both FDD and TD-LTE on a single semiconductor and software platform, in any 3GPP frequency band between 700 and 2700 MHz. The chipset supports throughputs in excess of 100 Mbps/50Mbps DL/UL respectively, and implements a high performance 20 MHz multiple input, multiple output (MIMO) receive architecture. In this set, 3100 is the LTE baseband processor and 6200 is the multi-band LTE-FDD MIMO transceiver.
By using a commercially ready LTE chipset, we are able to offer OEMs and ODMs a turnkey VoLTE solution that enables them to meet the needs of carriers in Asia, Europe and the U.S. with a single product, said Makishima.
Regarding LTE chip from Sequans, D2 used first-generation LTE baseband chip SQN3010 to demonstrate VoLTE viability. Meanwhile, Sequans has released a new second-generation LTE chipset with outstanding performance and extremely low power consumption in a very small package. The second generation baseband SQN3110 is implemented in 40 nm CMOS process with embedded SDRAM. Accompanying RFIC SQN3140 is a direction conversion transceiver.
