UWB chipset offers triple communications power

Milpitas, Calif. & Santa Clara, Calif.—Sigma Designs has started to sample CoAir, an Ultrawideband (UWB) and WiMedia standard-based chipset with combined wireless, coax and Ethernet capabilities.

Developed for worldwide service providers, telcos and consumer electronics manufacturers, Sigma's CoAir chipset is the only technology available in the world today that can simultaneously deliver multiple independent streams of video and data over coax cable, Ethernet cable and wirelessly without compromising quality of service and throughput, according to the company. It is a high performance “wireless” and “no new wires” product that can stream abundant content wirelessly and over existing coax and Ethernet wires for additional whole home coverage, up to 330 ft.

Based on the WiMedia standard, the CoAir chipset can achieve data rates up to 480-Mbit/s with UWB wireless for in-room video streaming. At the same time, CoAir has the capability to transfer data/video using UWB-over-coax with data rates also up to 480 Mbps for room-to-room communications. Gigabit Ethernet can also be operated simultaneously to support Ethernet-enabled devices.

Sigma's CoAir is an all CMOS product that consists of an RF radio chip (Sigma's B7CW101) and a baseband chip (Sigma's B7CC401). The RF radio chip supports three antennas for a reliable wireless link. The baseband integrates the OFDM PHY baseband, MAC—both based on the WiMedia Alliance standard—and a high performance 32-bit RISC processor. The chipset supports input/output ports for antennas, coaxial cable and Ethernet cable (CAT5). The chipset is also powered by the Transparent, Ubiquitous and Synchronous Cables & Air Network (TUSCAN), a patent-pending technology developed by Sigma Designs.

Pricing: $20 to $30, depending on volume.
Availability: By end of year, with limited samples available now.
