6 GE MDS entraNET Reference Manual 05-4055A01, Rev. D

1.2.1 Model Offerings

The GE MDS entraNET system includes two primary radio types— APs

and Remotes. Table 1-1 summarizes the interface capabilities for each

entraNET radio type.

NOTE: A Remote serves only one endpoint MAC address, even if a

bridge or hub is used.

1.3 APPLICATIONS

The following sections describe typical entraNET installations. All

installations should be reviewed by a network manager to ensure proper

integration with existing equipment.

1.3.1 Long-Range Wireless LAN

The wireless LAN is a common application of the entraNET system. It

consists of a central control station (AP) and one or more associated

Remote radios, as shown in Figure 1-2 on Page 7. A LAN provides com-

munications between a central LAN/WAN and remote Ethernet end-

points. Remote radios can support one Ethernet endpoint each.

The operation of the radio system is transparent to the computer equip-

ment connected to it. As such, the system behaves just as it would in a

hardwired arrangement, with respect to data format and integrity.

Over-the-air messages are exchanged at the Ethernet level, including all

types of IP traffic.

Antenna Placement

The AP antenna is positioned at a location from which it can reliably

communicate with all of the Remote radios in the system. Commonly,

this is a relatively high location on top of a building, communications

tower or other elevated point.

Communication Rules

• A Remote transceiver can only talk over-the-air to an AP.

• Peer-to-peer communications between Remotes can take place indi-

rectly through the AP.

• An AP can only talk over-the-air to Remote radios; however, two

APs can communicate with each other through their Ethernet con-

nectors when a wired LAN/WAN is utilized.
