Base Station Functions

1.3.1 Base Station .unctions
As a base station, the 9150 provides a link between the local area network and the
wireless network consisting of Teklogix mobile terminals, and base stations such as
the 9140 Wireless Gateway. The 9150 and 9400/9300 Network Controller (or host
using a Teklogix Software Development Kit) communicate using the 9010 propri-
etary protocol with TCP/IP over Ethernet, Token Ring or serial connectivity. Wlan
protocol enables the 9150 to communicate with 9140s without cable attachments
(see Figure 4.1 on page 47).
For information on configuring the 9150 as a base station, see Chapter 4: "Base
Station Configuration". For details on Wlan, see "Wlan Protocol" on page 8.
1.3.2 Mini-Controller .unctions
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 9400/9300
Network Controller.
To configure the 9150 as a mini-controller, see Chapter 5: "Mini-Controller Config-
uration". For a generalized system diagram, see Figure 5.1 on page 78.
1.3.3 Access Point .unctions
As an access point, 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 802.11 RF
data link with terminals and over a cable with a network controller or a host com-
puter. The 9150 can be connected to the network through an Ethernet or Token Ring
connection. The diagram in Figure 6.1 on page 125 illustrates a 9150 access point
connection between a Teklogix 9400 Network Controller on Ethernet and IEEE
802.11 wireless devices. Figure 1.4 on page 12 shows a generalized Token
Ring configuration.
For information on the 9150 as an access point, see "IEEE 802.11 Protocol" on
page 10 and Chapter 6: "Access Point Configuration".
