Figure 1 Network Topology
Access Point vs. Client
The access point unit acts as the wireless master unit. The access point accepts and authorizes links
initiated by client units, and controls the wireless communications. Clients (Stations) are slave units and
when connected to the access point becomes transparent Ethernet link. Figure 2 shows a connection
between two Ethernet devices using 245U-E Ethernet modems. In this example, one 245U-E is configured
as an access point and the other as a client.
Figure 2
Access Point and Client (Example 1)
Figure 3 shows an existing LAN being extended using 245U-Es. In this example, the access point should be
configured at the LAN end, although the wireless link will still work if the client is at the LAN end.
Figure 3
Access Point and Client (Example 2)
An access point can connect to multiple clients. In this case, the access point should be the central unit.
