Radio coverage

Radio coverage is a method for determining the ideal mounting points for WLAN access points within a building or in an open space. The probable signal strength is measured at various possible installation points in order to ensure that interference-free network access is possible from every point of the area to be illuminated. This enables WLAN clients to move freely within this area or building without losing the wireless network connection. This procedure is particularly relevant for larger companies and institutions whose buildings extend over a large area. In the area of licensed fixed data radio networks, the radio coverage on site serves three purposes in particular:

The quantity structure (for tenders) is determined. These are in particular the mast lengths, coaxial cable lengths and types, antenna types and information on the installation locations.
Determination of the coordinates of the individual stationary locations and their drawing in topographic map systems (TOP 50 of the state survey offices) as well as the creation of the terrain sections with distances.
Calculation of the radiated transmission power (ErP) for each station taking into account the attenuation chain calculation. These data are u. a. required for the license application to the Federal Network Agency.

The following information is required for each station for licensing:

Position in WGS-84 format
Height above sea level (NN)
Height of the antennas above ground
Type, gain and orientation of the antenna
RF output power of the transmitter
Damping chain calculation
radiated transmission power

In addition, a topographical overview plan of the stations on a scale of 1: 20000 must be attached to the application for the issue of the license certificate.
