Wireless Compatibility Approved

A proposal that proponents claim will insure compatibility between Bluetooth and 802.11b wireless local area networks was confirmed this week by a key unit of the Institute of Electrical and Electronics Engineers (IEEE).

The proposal, initially made by Mobilian Corporation and Symbol Technologies, was confirmed by IEEE's 802.15.2 Coexistence Task Group as a "recommended practice" by vendors.

The proposal, which the companies say they will publish later this year, describes an intelligent "traffic cop" to optimize throughput when the two systems are located on the same device. The system, according to Mobilian and Symbol, virtually eliminates interference.

Bluetooth is an increasingly-accepted short-range wireless technology while 802.11b is widely used for wireless LANs both in the home and the enterprise. Many analysts have said that interference with wireless LANs has been one of the factors holding back acceptance of Bluetooth.

The companies said in a statement that the approval means that chipmakers can implement technology this year so the two technologies can peacefully co-exist.
