Cambridge ultra wideband (UWB) developer Artimi has demonstrated the broadcast and reception of packet transmission via a wireless UWB network.
The firm claims it is the first example of a UWB multimedia and data transmission in a real-world environment, from a standard NDIS driver on one PC to a standard NDIS driver on another.
Though the demonstration system is currently limited by the FPGAs, production systems will transfer data in excess of 500Mbit/s, and potentially at gigabit/s speeds, said Mark Moore, Artimi’s CTO. Real world data-rates above 480Mbit/s are essential to deliver USB 2.0 cable replacement products.
Although the IEEE’s 802.15.3a standard continues to go through a tortuous approval process, Moore said building a product was a crucial step for the firm, and ideally the first silicon will be software upgradeable to the emerging standards. Production of the single chip silicon is expected in the first quarter of 2005.
From our perspective it’s actually more important to get a product into the market as soon as possible, said Moore. If you look at the overall system, an awful lot of the work is centred around complying with the FCC regulations, doing a good job on the wavefront and on the radio, and that’s independent of which way the standard falls in the end.
Both the IEEE and the consumer device-led Multiband OFDM Alliance should produce fairly stable-looking standards by the end of the year, Moore added.
