Wireless Network Topologies

The Harmony 802.11a Access Point is used to extend the capability of an existing
Ethernet network to devices on the 802.11a wireless network. The 802.11a devices
can connect to a single Access Point, or several Access Points can be configured to
form a single wireless network over a large area, allowing mobile clients to roam from
one Access Point to another.

Connecting to a Single AP

Mobile clients equipped with 802.11a wireless adapters are configured to operate in
Infrastructure mode and have the same SSID and security settings as the Access Point
in use on the Ethernet network.
