1.4 Radio Options
The 9150 supports 802.11b WLAN CF card USI radio Model CF-B-AG-02.
1.5 Radio Protocols
RF protocols allow terminals to communicate with a base station by sharing the use
of a radio channel in an efficient way. Teklogix systems use one of three types of RF
protocols: the Teklogix Adaptive Polling/Contention protocol, the Teklogix Wireless
LAN (Wlan) protocol, or the non-proprietary IEEE 802.11b protocol. When used as
a base station, the 9150 uses either the Adaptive Polling/Contention protocol or the
Wlan protocol. These protocols cannot be mixed on a single system. When used as
an access point device, the 9150 employs the IEEE 802.11b protocol. The protocols
are described in the following sections.
