PAGE 22
Chapter 1: Introduction Access Point Functions 1.3.1 Access Point Functions As an access point connected to a wired network, the 9150 Wireless Gateway forms a communication link between Teklogix RF terminals or wireless access point clients and a Teklogix Network Controller or a host computer. It communicates over an IEEE 802.11b RF data link with terminals, and over a cable with the network controller or a host computer. The 9150 can be connected to the network through an Ethernet connection.
PAGE 23
Chapter 1: Introduction Radio Options 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.
PAGE 24
Chapter 1: Introduction IEEE 802.11b Protocol 1.5.1 IEEE 802.11b Protocol The IEEE 802.11b protocol is an OSI standard for Wireless Local Area Networks (WLANs). With this standard, any IEEE 802.11b radio can communicate with any other similarly-equipped device. However, IEEE 802.11b does not provide a standard for a total WLAN system. IEEE 802.11b solely standardizes two communications layers: Physical (PHY) and Medium Access Control (MAC). Three different PHY layer media are covered: 2.
PAGE 25
Chapter 1: Introduction IEEE 802.11b Protocol 1.5.1.1 Inter-Access Point Protocol (IAPP) The Inter-Access Point Protocol (IAPP) is an extension to the IEEE 802.11b protocol. IAPP facilitates roaming of mobile stations across different Basic Service Sets (see Note below) and specifies how access points communicate with each other.

PAGE 27
Chapter 1: Introduction Wlan Protocol Only one base station or terminal may transmit at one time. When the channel is clear, a combination of preset priorities and random choices determines who “goes next”. Even if two transmitters attempt to send at the same time, message acknowledgements and retransmissions prevent any data from being lost. Terminals moving through the Wlan communicate with the base stations that provide the best communication path to a wired base station.
