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. The diagram in Figure 4.1 on page 61 illustrates a 9150 access
point connection between a Teklogix 9400 Network Controller on Ethernet and
IEEE 802.11 wireless devices.
Two 9150 Wireless Gateways can be used as an 802.11b bridge connecting two sep-
arate wired networks. Another feature is that the 9150 can be used as an 802.11b
wireless access point to extend coverage area or for locations difficult to wire (see
Figure 1.4 on page 10). For information on the 9150 as an access point, see “IEEE
802.11b Protocol” on page 8 and Chapter 4: “Access Point Configuration”.
1.3.2 Base Station Functions
As a base station or Remote Radio Module (RRM) connected to a wired network,
the 9150 provides a link between the local area network and the wireless network
consisting of Teklogix mobile terminals, and wireless base stations such as the 9150
Wireless Gateway. The 9150 and 9400 Network Controller (or host using a Teklogix
Software Development Kit) communicate using the 9010 proprietary protocol with
TCP/IP over Ethernet connectivity. Wlan protocol enables the wired 9150 to com-
municate with 9150s without cable attachments (see Figure 5.1 on page 100).
For information on configuring the 9150 as a base station or RRM, see Chapter 5:
“Base Station Configuration”. For Wlan, see “Wlan Protocol” on page 11.
1.3.3 Mini-Controller Functions
The 9150 is equipped with some emulation capabilities, allowing it to act as a mini-
controller. When a 9150 is configured as a mini-controller, Teklogix terminals can
emulate an ANSI, 5250 or 3274 terminal via a 9150 rather than through a 9400
Network Controller.
To configure the 9150 as a mini-controller, see Chapter 6: “Mini-Controller Config-
uration”. For a generalized system diagram, see Figure 6.1 on page 142.
