Proxim 802.11a solutions support IEEE 802.1x with dynamic per user, per session re-keying and RADIUS-based
authentication. This standards-based solution authenticates via existing databases and provides the best
scalability for large enterprise deployments. For smaller enterprise deployments, Proxim’s built-in VPN tunnel
allows administrators to utilize existing VPN servers to secure their wireless network, saving cost and
complexity. Whichever method is chosen, 802.1x or a VPN, you can be assured of a secure, private 802.11a
network. In addition, future 802.11i solutions promise even stronger encryption yet based on TKIP and AES
standards. Proxim Corporation products will support those standards as they become available. Proxim is
already the first 802.11a manufacturer to support 802.1x technology in its products.
“With the Harmony architecture, users can roam subnets without any difficulty, which is not
possible with most WLAN implementations…Proxim’s Harmony allows 802.11b, 802.11a, and
OpenAir wireless devices to coexist and interoperate on the same network. That means end-users
can communicate with each other, regardless of what kinds of devices they use, and all devices
can be centrally managed form a (single) web interface. Best of all, Harmony does not require
that any additions be made to the network.”

Harmony 802.11a—built-in manageability.
Although wireless connectivity frees the user to access the network when and where he or she chooses, it poses a
challenge to administrators. How does one deal with many users, each capable of moving their physical
location, roaming across subnets in typical enterprise networks? The answer is found in 802.11a implementations
such as those from Proxim Corporation that allow administrators to deploy wireless LANs easily within the
existing routed network without setting up a single VLAN or subnet for the wireless access points.
The Proxim 802.11a solution is unique in that it offers an optional Access Point Controller. This device, housed
in the server room, allows the network administrator to control all access points in the network from a single
central monitoring station. The Access Point Controller greatly simplifies installation by configuring APs
automatically, it enhances security with a built-in VPN tunnel and IP firewall, and it lets wireless devices roam
across subnets without any special software required on the client or the network.
