Arraycomm + Alvarion = Smart Beaming

Posted by samc on July 27th, 2007

Wireless broadband equipment leader Alvarion and smart antenna company ArrayComm, announced today their ongoing technology partnership for integration of ArrayComm’s multi-antenna signal processing software (A-MASTM) into Alvarion’s 4Motion’s Radio Access Network.

Alvarion’s all-IP OPEN WiMAX will leverage ArrayComm’s A-MASTM Advanced Multi-Antenna software in order to offer 2 to 4 times more coverage and spectral efficiency than the WiMAX Forum’s baseline profiles, says the company. A unique combination of Beamforming, MIMO and adaptive interference cancellation, is the secret sauce. Alvarion says it maintains full profile and standards compliance.

“ArrayComm’s Multi-Antenna Signal processing (MAS) technology significantly improves the economics of WiMAX systems, increasing the range and data throughput per base station,” said Tzvika Friedman, President and CEO of Alvarion. “The relationship between the two companies will benefit operators worldwide with solutions that use ArrayComm’s unique A-MAS software and our WiMAX radio network.”

In the Arraycomm philosophy of beamforming (pdf), all architectures start with two or more antennas on one or both ends of the communication link (i.e. the base station and/or the client device), and they perform some degree of coordinated processing on the signals to and/or from these antennas, increasing both the up and downstream signal strength.

Compliant with IEEE 802.16e-2005 standards, Alvarion’s 4Motion is said to deliver all the promise of mobile WiMAX with advanced access technologies, including software defined radios, scalable OFDM, smart antennas, MIMO, and dynamic bandwidth allocation. It leverages Alvarion’s BreezeMAX base stations, the most popular WiMAX system in the world with more than 150 networks installed to date.
