NEC America Inc. (NEC) announced its strategy to deliver an IEEE802.16e-2005 standard-based Mobile WiMAX solution aimed at the U.S. market. With a strong history in deploying digital microwave technology, NEC has the capability to help operators deliver high-speed, carrier-grade Ethernet data communications via a wireless network, which can allow operators a swift rollout of both fixed and mobile IP services.

NEC intends to release an IEEE802.16e-2005 standard-compliant solution including SOFDMA technology and downlink partially utilized sub-channels (PUSC), which can enhance the system performance when compared to the previous 802.16-2004 standard. This new standard addresses mobility extension, which can provide more opportunities. In addition, the NEC flexible and low latency design can permit multiservice provisioning for data, voice and video at optimum quality.

NEC's Mobile WiMAX solution can be introduced either as a full mobile capable platform from the beginning or in a multiphased approach starting from a fixed broadband access service to complement xDSL and FTTx systems. It can also serve as an alternative access method for new carriers that can migrate in the future to a full mobility platform--in order to allow roaming between base stations, laptops, PDA users and mobile handsets, portable entertainment players and game terminals--using the same base station hardware. Initially, NEC intends to deliver WiMAX for broadband Internet connections to customers through digital waves that provide connections between direct fixed and mobile subscribers as well as backhaul networks for WLAN hotspots. The technology can allow users to build reliable WMAN networks covering a wider area than Wi-Fi hot spots using licensed frequency bands.
