1.1.1 Model Offerings
The transceiver comes in two primary models—Access Point and
Remote. Three types of Remote Gateways are available—the Ethernet
Bridge, the Serial Gateway, and the Dual Gateway supporting both
IP/Ethernet and serial services. Table 1-1 summaries the different inter-
face abilities for each type.
A unit can be configured by the owner to operate as an Access Point or
as a Remote with some restrictions. Only the Dual Gateway Remote
units can be reconfigured as an Access Point. Ethernet Bridge and a
Serial Gateway Remotes cannot be reconfigured as Access Point unless
they are first upgraded to Dual Gateway type. This is accomplished with
an “Authorization Key” purchased from the factory. Each one of these
individual software keys is associated with the serial number of the cor-
responding unit.
1.2 APPLICATIONS
The following sections provide illustrations of typical transceiver instal-
lations. This is meant as an overview only. It is recommended that a net-
work manager be involved in all installation planning activities.
1.2.1 Wireless LAN
The wireless LAN is the most common application of the transceiver. It
consists of a central control station (Access Point) and one or more asso-
ciated Remote units, as shown in Figure 1-2 on Page 6. A LAN provides
communications between a central WAN/LAN and remote Ethernet
segments. The operation of the radio system is transparent to the com-
puter equipment connected to the transceiver.

NOTES
1. Provides access to the embedded Management System on all units.
2. Can be upgraded to Dual Gateway with an Authorization Key.
3. Can be configured as an Access Point or Dual Gateway through the
embedded Management System.
4. In addition, the iNET II is available. This model operates at 512/1024
kbps under the FCC DTS rules, which allow wider modulation band-
widths to be employed.
