Company to Demo HDTV Over 802.11a

On Tuesday, Magis Networks, Inc. announced that it will be holding a demonstration of a 5 Ghz, 802.11a transmission of HDTV. The demonstration is set to take place at the Western Cable Show, Nov. 28-30, in Anaheim, CA, at the Magis booth, number 1009. This is a significant test of the transmission capabilities of products in the 5 GHz band because of the large amount of data required for the high-resolutions output by HDTV.

Magis itself is a developer of chipsets for the 5 GHz frequency band, which includes bit rates up to 54 Mbps under the proposed IEEE 802.11a standard. The chipsets are designed to support TCP/IP data and audio/video.

Magis stated that the upcoming demonstration will transmit HDTV wirelessly from an access point to a remote terminal. Magis' Air5 chipset technology supports 802.11a, HiperLAN2, and wireless 1394 standards. Proposed applications of the chipset technology include digitial cable set-top boxes, cable modems, satellite receivers, PCs, PDAs, TVs, PVRs, DVDs, Internet appliances, and gaming consoles. The Air5 products use the Orthogonal Frequency Digital Multiplexing (OFDM) modulation schema.

In terms of its support for transmitting HDTV wirelessly, the company reported that the Air5 technology meets the QoS (Quality of Service) requirements of HDTV broadcast-quality video, DVD, wireline voice, and CD-quality audio.

Information about the Air5 products and white papers regarding QoS and OFDM can be found at the Magis Web site.
