No Standard For Next-Gen Wireless
Posted: 26th Sep, 2003 By: MarkJ
The next-generation of hi-speed wireless technology, known as UltraWideBand (UWB), may see a delay following disagreements over the best (technically and legally) standard to use:
At an IEEE meeting in Singapore last week, the Intel/TI proposal received the most votes for the second time, but failed to gain the 75 per cent required for adoption. Both its submission and Motorolas are based on Ultrawideband (UWB) technology, but the Intel-led group uses multiple bands to boost performance to 660Mbps over five meters or 188Mbps over ten meters. Motorola uses a single-band approach and claims multi-band breaks US FCC frequency regulations. The FCC last week refused to make a decision on this debate, passing the buck back to the IEEE to test any technology and ensure that it complied with regulations.
It seems that the vote was similar to that in a previous meeting in July, with about 60 per cent going to the Multi-band OFDM Alliance. A further vote will be held next week.
Apart from uncertainty over the FCC, the other main objection to the Intel proposal is that it does not guarantee zero-royalty intellectual property licensing, only a "reasonable and fair" licensing policy.
