Wireless Network Topologies
The re-association capabilities of the IEEE 802.11 standard enable clients to move throughout the wireless
LAN area and roam between access points. Re-association can occur as long as the ECB has the same ESSID
(network name) as the AP to which it is trying to make a connection.
Ad Hoc Topology
The 802.11 Ad Hoc topology allows multiple ECB units to communicate directly with each other, without the
need for an access point (AP) or other wireless infrastructure. Figure 2 shows a network in which four ECB
units are used to provide wireless connectivity between Ethernet devices.

ECB
In this configuration, the ECB units make all three devices appear to be connected by the same Ethernet
cable. Using ECB units in this manner provides a cost effective way to wirelessly link a small number of
Ethernet devices. In addition, ECB units eliminate the need to install expansion cards or driver software.
NOTE: A single ECB is only capable of bridging for a single Ethernet device. A single ECB cannot be
connected to a hub and bridge for multiple Ethernet devices on the hub.
