noise ratio (SNR) falls below 15 dB. If the ratio falls below this value, a new radio cell should be started.
The typical circumference of a radio cell in a building is up to 50 m.
For the tool to be able to connect to different access points automatically (roaming), the SSID and encryp-
tion must be set identically at the corresponding access points.
-
area coverage with controlled emission from multiple access points is required, corresponding plan-
ning and evaluation must be carried out for the specific case.
Example installation 5 GHz
• Several overlapping radio cells are possible, even if only one free channel is used.
• Up to 200 tools are then possible within the radio range with a limited volume of data.
• The range of the radio cells is limited by the minimal transmission power.
