How Many Types of Target Coverage Areas Are There on WLAN Networks? What Are Field Strength Requirements in These Areas?

WLAN networks involve the following target coverage areas:
l Major coverage areas: places where many users need to connect to the Internet, such as
dormitories, libraries, classrooms, hotel lobbies and guest rooms, meeting rooms, offices,
and exhibition halls.
l Minor coverage areas: places where few users need to connect to the Internet, such as
bathrooms, stairways, lifts, corridors, and kitchens.
l Special coverage areas: special areas where users allow or prohibit WLAN access.
Depending on WLAN access requirements in the preceding areas, various field strengths must
meet the following requirements:
l Hotspot field strength: The field strength in major coverage areas ranges from -40 dBm
to -65 dBm. A field strength higher than -40 dBm may cause receiver overload, and a
field strength lower than -65 dBm may reduce the network connection rate.
l Edge field strength: It is determined based on the receiving sensitivity and edge
bandwidth. Generally, the edge field strength should be higher than -75 dBm. The
network connection rate in minor areas can be lower than that in major areas.
l Interference field strength: The co-channel interference strength in an area cannot exceed
-80 dBm.
l Leakage field strength: The leakage field strength 10 m away from a building cannot
exceed -90 dBm.
