Leading 4G WiMAX Equipment Manufacturers Enhance Mobile WiMAX

Broadband Mobile WiMAX (News - Alert) standard will never be the same again as the WiMAX Forum announced that a group of leading 4G WiMAX equipment manufacturers, service providers and chip companies have reached a major milestone in advancing the speed of data and the efficiency of broadband wireless networks based on the 802.16e Mobile WiMAX standard at the WiMAX Forum Global Congress in Amsterdam this week.
Technical experts from Alvarion, Beceem (News - Alert), Clearwire, Fujitsu, GCT Semiconductor, Hitachi, Huawei, Intel, Motorola, NEC, Samsung, Sequans, UQ and ZTE have created a proposal on enhancements to the IEEE (News - Alert) 802.16e mobile WiMAX standard for submission into the next WiMAX Forum certification release. This proposal documents how the performance enhancements are to be implemented in future WiMAX products in a way that further ensures their interoperability and broad commercial availability.
Ron Marquardt, VP of technology for Clearwire said, “On average, our mobile 4G customers are consuming more than seven gigabytes of data every month. We’re committed to constant innovation and these enhancements to the 802.16e standard will increase our ability to meet the incredible demand for super fast mobile Internet both in the home and on the go.”
Dr. Fumio Watanabe, CTO of UQ Communications Inc said, "Despite the great progress the WiMAX industry has made over the past couple of years with an explosion of new networks and devices, we are not resting on our laurels. UQ has already upgraded almost all devices in its network to be capable of more than 20 Mbps downlink speeds. We are pleased to see the industry banding together to further accelerate the performance and efficiency of today's WiMAX technology networks even as we continue to make plans for the next generation of WiMAX technology - 802.16m."
The specific enhancements to the 802.16e Mobile WiMAX standard include increased data uplink and downlink budgets that improve the performance of WiMAX devices operating at the outer edges of a WiMAX cell or enable the service provider to increase the coverage of a given cell, up to 70 percent improved spectral efficiency and an associated potential doubling of peak data rates, new technologies for reducing signal interference both within cells and among cell sites, and improved frequency Reuse 1 deployment schemes.
These enhancements will be achieved via software-only upgrades for WiMAX enabled client devices. There also are optional provisions to increase performance by way of hardware additions as in the case of adding antennas to base stations.
The WiMAX Forum is targeting validation of equipment that incorporates these new enhancements before the end of this year which would lead to certified products from multiple vendors starting in 2011.
Read here about how Motorola (News - Alert), a dealer in communications, has stated that they have unveiled a new cost-effective single RAN solution that has the ability to enable WiMAX evolution. Using the new solution, operators can upgrade existing WiMAX 802.16e / 802.16e enhanced networks to 802.16m or TD-LTE (News - Alert) or to add LTE to their existing WiMAX networks.
