L&T Unveils LTE Device Software

DALLAS -- L&T Infotech (http://www.Lntinfotech.com) announced today the availability of its 3GPP release LTE UE (User Equipment) protocol stack (Ver 8), helping to reduce time-to-market of LTE terminal devices.

L&T Infotech has developed LTE protocol stack, leveraging its vast experience in wireless technologies like CDMA, UMTS, EVDO, WLAN and WiMAX. The solution comprises Access Stratum and Non Access Stratum (NAS) layers as defined by 3GPP standards. L&T Infotech's LTE UE stack is compliant to March '09 3GPP Release 8, LTE specifications.

The design is modular to accommodate further releases of the Release 8 Standard. The implementation is agnostic of underlying operating system and hardware. The data plane (MAC, RLC and PDCP) is extensively tested for all 8 Data Radio Bearers (DRBs) at UE simultaneously, with both Tx and Rx path configurations for various combinations of UM and AM mode. The Control Plane (RRC and NAS) supports L2/L1 configurations, bearer establishment, cell selection and mobility procedures.

"L&T Infotech believes that LTE is the clear evolutionary path for existing technologies of 3GPP origin and also for 3GPP2, CDMA technology for meeting the IMT-Advanced requirements. Hence, L&T Infotech is committed to provide products and solutions to reduce time-to-market of LTE devices to operators, OEMs and chipset manufacturers," said Mr. Sudip Banerjee, Chief Executive Officer, L&T Infotech.

"L&T Infotech's LTE UE stack product enables our customers access to LTE protocol implementation, with proven test compliance to 3GPP-defined test suites. The LTE UE stack supports different UE categories based on the form factor and target platform. Extensive diagnostic and configuration tool of the LTE UE stack provides comprehensive view of the stack behavior with statistics of data packets flow across L2 layers, QoS Parameter fine tuning, RSSI, CINR measurements, and logging facility," said Mr. Isaac Sundarajan, Executive Vice President, Product Engineering Services BU, L&T Infotech.
