Today's Mobile WiMAX technology based upon the IEEE 802.16e standard is field proven with more hundreds of deployments worldwide providing services for fixed, nomadic, and mobile broadband applications. However, with global mobile data traffic explosion, it is imperative to advance the performance of 4G solutions in order to improve the business model for service providers.
The next release of Mobile WiMAX, WiMAX 2, will be based upon IEEE 802.16m. IEEE 802.16m meets the International Telecommunications Union requirements for 4G, or “IMT-Advanced,” delivering higher peak throughputs - more than 300 Mbps in a 20 MHz channel - lower latency and increased coverage and VoIP capacity. IEEE 802.16m also introduces the ability to aggregate multiple RF carriers, making peak data rates of more than 1 Gbps possible in 100 MHz of effective bandwidth. Enhanced support for multi-hop relays and femto-cells provide operators with better tools for improving coverage while enhanced broadcast and location-based features enable premium applications and services.
WiMAX 2 is also provide complete backwards compatibility with today's Mobile WiMAX, which enables current devices to work seamlessly on a WiMAX2 network.
Samsung leads the industry to accelerate the implementation of WiMAX 2 equipment and devices, while also working to improve the economics of mobile broadband.
