SAN JOSE, Calif. – Redpine Signals, Inc. completed the design of a low power Wi-Fi block based on the 802.11ac standard that supports up to a Gbit/second of throughput over 5 GHz spectrum. The Quali-Fi block uses approximately the same amount of power as its previous 802.11n design, the company claims.
Redpine (San Jose) will license the technology to one mobile applications processor vendor, the company's third licensing deal in ten years following agreements with Portal Player and Infineon. It also will embed the block in its own multi-mode wireless chip slated for mid-2012.
The new block can support MIMO (multiple input, multiple output) antennas in configurations ranging from 1x1 to 3x3. It dissipates less than 1 milliwatt in standby mode and has been implemented both as an FPGA and ASIC.
Venkat Mattela, chief executive of Redpine, said he expects companies to start volume shipments of .11ac chips probably late in 2012. One startup recently started limited sampling of its .11ac design.
Analysts and vendors expect .11ac, will become the next iteration of Wi-Fi. It is being implemented in combo chips that also support .11n and are now starting to sample with production expected next year.
