Initiated in 2004, the Long Term Evolution (LTE) project focused on enhancing the Universal Terrestrial Radio Access (UTRA) and optimizing 3GPP’s radio access architecture. Targets were to have average user throughput of three- to four-times the Release 6 HSDPA levels in the Downlink (100Mbps), and two to three times the HSUPA levels in the Uplink (50Mbps).
In 2007, the LTE of the 3rd generation radio access technology – "E UTRA" – progressed from the feasibility study stage to the first issue of approved technical specifications. By the end of 2008, these specifications became sufficiently stable for commercial implementation.
LTE’s E UTRA will be extremely flexible, using a number of defined channel bandwidths between 1.25 and 20 MHz (contrasted with UTRA’s fixed 5 MHz channels). Leveraging its strength in wireless network and IP expertise, CommVerge Solutions offers extensive planning in deploying 4G technology such as LTE (Long Term Evolution).
As 3GPP is defining IP-based, flat network architecture as part of the System Architecture Evolution (SAE) effort. CommVerge is continuously involved in defining what it takes on the LTE–SAE architecture and concepts that have been designed for efficient support of mass-market usage of any IP-based service. The architecture is based on an evolution of the existing GSM/WCDMA core network, with simplified operations and smooth, cost-efficient deployment.
Orthogonal Frequency Division Multiplexing (OFDM) has been selected for the Downlink and Single Carrier-Frequency Division Multiple Access (SC-FDMA) for the Uplink. The Downlink will support data modulation schemes QPSK, 16QAM, and 64QAM and the Uplink will support BPSK, QPSK, 8PSK and 16QAM.
CommVerge Solutions knows what it takes to design, implement and maintain an LTE infrastructure. We understand the unique requirements for each carrier in their own respective region needs to implement such technology. From Backhaul to Infrastructure to Service Delivery framework, CommVerge capabilities in planning, designing and implementing such technology has been derived from extensive research and exposure to various wireless networks. This variety requires a technology and services partner that understands the ever-changing Carrier climate and technology evolution.
