7Transmit power / Power densityMax. 1 W e.i.r.p.
Max. 50 mW/MHz e.i.r.p. density in any 1 MHz band.
WAS/RLANs operating in the band 5470 - 5725 MHz shall either employ transmitter power control (TPC), which provides, on average, a mitigation factor of at least 3 dB on the maximum permitted output power of the systems; or if transmitter power control is not in use, the maximum permitted e.i.r.p. and the corresponding e.i.r.p. density limits shall be reduced by 3 dB.
Type of Antenna: integral or dedicated.
8Channel access and occupation rulesDynamic Frequency Selection (DFS).WAS/RLANs operating in the bands 5470 - 5725 MHz shall use mitigation techniques that give at least the same protection as the detection, operational and response requirements described in EN 301 893 to ensure compatible operation with radiodetermination systems (radars). Such mitigation techniques shall equalise the probability of selecting a specific channel for all available channels so as to ensure, on average, a near-uniform spread of spectrum loading.
The equipment shall implement an adequate spectrum sharing mechanism in order to facilitate sharing between the various technologies and applications. The adequate spectrum sharing mechanism can be e.g. LBT (Listen Before Talk), DAA (Detect And Avoid) or any other mechanism providing a similar level of mitigation.
9Authorisation regimeSwitzerland: License exempt.
Liechtenstein: General authorisation.
Operation on NIB / NPB. (Non interference basis / non protection basis).
