AP-4131 Access Point Product Reference Guide 87
3. 802.15 (draft) Bluetooth Co-existence allows access points and MUs to
share Spectrum24 network resources with Bluetooth RF terminals. The
802.15 (draft) Bluetooth Co-existence value is communicated to MUs via
access point beacons. When a non zero-value is entered, Symbol
802.11b devices stop transmitting for the duration of that interval. This
allows Bluetooth devices (which are very low power) an opportunity to
communicate. This feature should only be used with Bluetooth terminals
because it reduces the total throughput of all 802.11 devices.
