The first single-chip WiMAX Wave 2 femtocell has been unveiled by picoChip. Femtocell access points are optimized for deployment inside buildings to improve coverage and data rates. The second version of the industry-standard WiMAX base station reference design, the PC6532, integrates full PHY and MAC into a single picoArray-based PC205 processor, as with the Wave 1 design, and it offers seamless software upgrade for existing picoChip PC6530 Wave 1 designs.

Wave 2, the latest version of the WiMAX standard, adds increased support for mobility, while Multi Input Multi Output (MIMO) increases data-rate and reliability by simultaneously sending and receiving data via multiple antennas. The PC6532 supports Wave 2 and full IO-MIMO, with Matrix A and Matrix B downlink, and both MRC and UL-CSM uplink.

"Once more, picoChip demonstrates the power of its software-defined architecture, and we are delighted to be working as partners," commented Paul Senior, CTO of Airspan. "The efficiency of the single-chip solution is attractive, furthermore the ability to seamlessly upgrade our current Wave 1 designs to Wave 2 and full MIMO in both uplink and downlink, gives us a significant advance in performance and capability over alternative solutions."

The picoChip WiMAX architecture is scaleable from femtocell access points to sophisticated multi-sector carrier macrocells with full support for IO-MIMO and beamforming. Both reference designs run on a single processor: the PC205 integrates an ARM processor for MAC functionality, and picoArray multi-core DSP for software defined PHY.

"The problem of good in-building coverage, and the opportunity for femtocells to address it, is becoming increasingly widely recognized," commented Simon Saunders, chairman of the Femto Forum. "With use of 2.5GHz and the business case for ubiquitous high-speed data this is even more important for WiMAX. The Femto Forum seeks to promote femtocells across all technologies and we are delighted our members are supporting these air-interfaces."

The PC6530 Wave 1 WiMAX reference design is available now and has already passed IOT testing. The seamless software upgrade to the PC6532 Wave 2 WiMAX femtocell reference design will be available in Q2 2008.
