ANNEX
Harmonised technical conditions for WAS/RLANs in the 5 150-5 250 MHz, 5 250-5 350 MHz and 5 470-5 725 MHz frequency bands
Parameter |
Technical conditions |
||||
Frequency band |
5 150 -5 250 MHz |
||||
Permissible operation |
Indoor, including installations inside road vehicles, trains and aircraft, and limited outdoor use (note 1). Use by unmanned aircraft systems (UAS) is limited to within the 5 170 -5 250 MHz band. |
||||
Maximum mean equivalent isotropically radiated power (e.i.r.p.) for in-band emissions |
200 mW Exceptions:
|
||||
Maximum mean e.i.r.p. density for in-band emissions |
10 mW/MHz in any 1 MHz band |
||||
|
Parameter |
Technical conditions |
||
Frequency band |
5 250 -5 350 MHz |
||
Permissible operation |
Indoor use: inside buildings only. Installations in road vehicles, trains and aircraft are not permitted (note 2). Outdoor use is not permitted. |
||
Maximum mean e.i.r.p. for in-band emissions |
200 mW |
||
Maximum mean e.i.r.p. density for in-band emissions |
10 mW/MHz in any 1 MHz band |
||
Mitigations techniques to be used |
Transmitter power control (TPC) and dynamic frequency selection (DFS). Alternative mitigation techniques may be used if they ensure at least an equivalent performance and level of spectrum protection in order to comply with the corresponding essential requirements of Directive 2014/53/EU and if they respect the technical requirements of this Decision. |
||
Transmitter power control (TPC) |
TPC shall provide, 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 mean e.i.r.p. and corresponding mean e.i.r.p. density limit shall be reduced by 3 dB. |
||
Dynamic frequency selection (DFS) |
DFS is described in Recommendation ITU-R M. 1652-1(3) to ensure compatible operation with radiodetermination systems. The DFS mechanism shall ensure that the probability of selecting a given channel is the same for all available channels within the 5 250 -5 350 MHz and 5 470 -5 725 MHz bands. The DFS mechanism shall also ensure, on average, a near-uniform spread of the loading of the spectrum. WAS/RLAN shall implement a dynamic frequency selection providing a mitigation against interference to radar at least as efficient as DFS as described in ETSI Standard EN 301 893 V2.1.1. Settings (hardware and/or software) of WAS/RLAN related to DFS shall not be accessible to the user if changing those settings results in the WAS/RLAN no longer being compliant with the DFS requirements. This includes (a) not allowing the user to change the country of operation and/or the operating frequency band if that results in the equipment no longer being compliant with the DFS requirements and (b) not accepting software and/or firmware which results in the equipment no longer being compliant with the DFS requirements. |
