1.2 APPLICATIONS
The following sections provide illustrations of typical MDS iNET 900
installations. Most installations will require some planning by a network
manager.
1.2.1 Wireless LAN
The wireless LAN is the most common application of the MDS iNET
900. It consists of a central control station (Access Point) and one or
more associated Remote units, as shown in Figure 1-2. 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 iNET 900 units.
The Access Point is positioned at a location from which it can commu-
nicate with all of the iNET Remote units in the system. Commonly, this
is a relatively high location on top of a building or communications
tower. Messages are exchanged at the Ethernet level. This includes all
types of IP traffic.
An MDS iNET 900 Remote can only talk over-the-air to an Access
Point (AP) unit. Peer-to-peer communications between Remotes can
only take place indirectly through the AP. An AP can only talk
over-the-air to iNET Remote units. Two iNET AP units can communi-
cate with each other through the Ethernet connector over a common
LAN/WAN.
