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

Table 1

WAS/RLANs in the 5 150 -5 250 MHz frequency band

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: — 40 mW maximum mean e.i.r.p. applies for installations inside train carriages with an attenuation loss on average of less than 12 dB; — 40 mW maximum mean e.i.r.p. applies for installations inside road vehicles. Maximum mean e.i.r.p. density for in-band emissions 10 mW/MHz in any 1 MHz band Note 1: If used outdoors, equipment shall not be attached to a fixed installation or to the external body of road vehicles, a fixed infrastructure or a fixed outdoor antenna.

Techniques to access spectrum and mitigate interference that provide an appropriate level of performance to comply with the essential requirements of Directive 2014/53/EU of the European Parliament and of the Council (1) shall be used. Where relevant techniques are described in harmonised standards or parts thereof the references of which have been published in the Official Journal of the European Union in accordance with Directive 2014/53/EU, performance at least equivalent to the performance level associated with those techniques shall be ensured.

WAS/RLANs in the 5 250 -5 350 MHz frequency 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. Note 2: Operation of WAS/RLAN installations in large aircraft () (excluding multi-engined helicopters) is permitted until 31 December 2028 with a maximum mean e.i.r.p. for in-band emissions of 100 mW.

Techniques to access spectrum and mitigate interference that provide an appropriate level of performance to comply with the essential requirements of Directive 2014/53/EU shall be used. Where relevant techniques are described in harmonised standards or parts thereof the references of which have been published in the Official Journal of the European Union in accordance with Directive 2014/53/EU, performance at least equivalent to the performance level associated with those techniques shall be ensured.

WAS/RLANs in the 5 470 -5 725 MHz frequency band

Parameter Technical conditions Frequency band 5 470 -5 725 MHz Permissible operation Indoor and outdoor use. Installations in road vehicles, trains and aircraft and use for UAS are not permitted (note 3). Maximum mean e.i.r.p. for in-band emissions 1 W Maximum mean e.i.r.p. density for in-band emissions 50 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 the 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 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 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/RLANs 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. Note 3: Operation of WAS/RLAN installations in large aircraft (excluding multi-engined helicopters), except in the frequency band 5 600 – 5 650 MHz, is permitted until 31 December 2028 with a maximum mean e.i.r.p. for in-band emissions of 100 mW.

Where relevant techniques are described in harmonised standards or parts thereof the references of which have been published in the Official Journal of the European Union in accordance with Directive 2014/53/EU, performance at least equivalent to the performance level associated with those techniques shall be ensured.
