Basic Service Area (BSA)
- The physical area of coverage provided by an access point in a BSS is known as the basic service area (BSA).
- Client stations can move throughout the coverage area and maintain communications with the AP as long as the received signal between the radios remains above received signal strength indicator (RSSI) thresholds.
- The size and shape of a BSA depends on many variables, including AP transmit power, antenna gain, and physical surroundings.
- Because environmental and physical surroundings often change, the BSA can often be fluid.
- When drawing a BSA, it is common to draw a circle around the AP to illustrate the theoretical coverage area.
- In reality, the real coverage area will have a disproportional shape due to the existing indoor or outdoor environment.
