Aruba rethinks WLAN setups

Aruba Wireless Networks is unveiling products it says will turn enterprise wireless LAN costs inside out.

Highlighting the company's new Wireless Grid are streamlined 802.11a/b/g access points that plug into an Ethernet wall outlet or become part of a structured cable deployment as combined access point/wall jack.

Also included is a switch, dubbed the 5100, that can take a second processing board to handle up to 3.6G bit/sec throughput for encrypted traffic. Switch software automates the ability for access points to handle different services, such as only 802.11a traffic, or radio frequency monitoring or location tracking.

To set up the grid, an Aruba AP 60 or 61 access point is plugged into a standard Ethernet wall jack.

The Model 60 has a detachable antenna that can be replaced with a higher-gain or directional antenna; the Model 61 has a built-in antenna. Both models use the Atheros 802.11a/b/g chipset and can transmit on 2.4-GHz or 5-GHz radio bands. The devices are loaded with client code to register and communicate with the new Aruba switch.

Aruba says the setup eliminates the high cost of wiring and installing access points in the spaces above hanging ceilings typically found in enterprise sites (installation charges commonly range from a few hundred dollars to as much as $1,000 per access point). Aruba now will charge a yearly fee of $200 to cover each access point and its software and maintenance, whereas in the past, the vendor charged separately for each.

Company officials say the pricing model will let customers better afford WLANs optimized for maximum performance: lots of Aruba access points that can be quickly and easily installed, with automatic adjustments to maintain high-bandwidth connections and minimize interference.

"Access point prices have fallen, [but] labor costs have continued to rise," says Craig Mathias, principal for Farpoint Group. "So why not just plug [access points] into the wall?"

Mathias says the Wireless Grid is not a new architecture in that it still relies on access points, but he says it should let customers deploy more of the devices where needed.
