Access Point 530

Infrastructure Wireless LAN with Roaming

The Basic Service Set (BSS) defines the communications domain for each

access point and its associated wireless stations. The BSS ID is a 48-bit binary

number based on the access point’s wireless MAC address, and is set automat-

ically and transparently as stations associate with the access point. The BSS

ID is used in frames sent between the access point and its stations to identify

traffic in the service area.

The BSS ID is only set by the access point, never by its stations. The stations

only need to set the Service Set Identifier (SSID) that identifies the wireless

network provided by one or more access points. The SSID can be manually

configured by the stations, can be detected in an access point’s beacon, or can

be obtained by querying for the identity of the nearest access point.

A wireless infrastructure can also support roaming for mobile workers. More

than one access point can be configured to create an Extended Service Set

(ESS). By placing the access points so that a continuous coverage area is

created, wireless users within this ESS can roam freely. All ProCurve

Networking wireless network cards, adapters, and access points within a

specific ESS must be configured with the same SSID.
