After A Slow Start, Bluetooth Shows Its Colors
Date Posted: June 24, 2002 12:00 AM
An alternative approach is offered jointly by Intersil, the leading 802.11b silicon supplier, and Silicon Wave, a leading Bluetooth supplier. They recently announced their Blue802 technology, which integrates both protocols into a dual-mode chip set aimed at the laptop market.
Bluetooth and 802.11b co-existence is so important that the IEEE has a separate working group (802.15.2) devoted to seeking a solution. Among potential answers is an adaptive frequency-hopping (AFH) algorithm for Bluetooth that would take fewer hops while attempting to stay away from frequencies used by the 802.11b radio. This solution is forthcoming after a rule change by the FCC and a blessing by the Bluetooth SIG.
If you're working on a Bluetooth PDA project, you may want to consider TDK's Go Blue Wireless Development Tool Kit. It prepares developers to demonstrate and validate designs quickly to reduce time-to-market. TDK also supplies "clip-ons" that give both Palm and Compaq iPAQ PDAs Bluetooth capability.
