Combined with engineering survey and architectural drawings, the main coverage areas and secondary coverage areas of WLAN network construction are defined, and coverage planning is focused on the areas where users are concentrated on the Internet.
The main coverage area: user centralized Internet access areas, such as dormitory rooms, libraries, classrooms. Hotel rooms/lobbies, meeting rooms, offices, exhibition halls and other places where people gather;
Secondary coverage areas: areas without Internet access need do not focus on coverage, such as toilets, stairs, elevators, corridors, kitchens and other areas;
Special area: The customer specifies areas to be covered or not to be covered
Field strength requirements:
Main Coverage Area: General Field Intensity Requirements at - 45 ~ - 65 dBm
Secondary Coverage Area: General Field Intensity Requirement is greater than -75 dBm
Special area: according to the specific needs of customers
In addition to the above three regional field strength requirements, there are also the following field strength requirements:
Edge field strength: Edge field strength evaluation combined with receiving sensitivity and edge bandwidth requirements to determine, generally choose more than - 75 dbm, reduce the link rate can also meet the needs of the Internet;
Jamming field strength: the same frequency interference in the same region is not more than - 80 dBm；
Leakage field strength: the leakage field strength of the system should not be too large, and the field strength at the periphery of the building should not be greater than - 90 dBm；
