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 fix ed 
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 Council1 shall be used. Where relevant techni ques 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 equi valent to the performance level associated with those 
techniques shall be ensured.  
  
                                                 
1 Directive 2014/53/EU of the European Parliament and of the Council of 16 April 2014 on the 
harmonisation of the laws of the Member States relating to the making available on the market of radio 
equipment and repealing Directive 1999/5/EC (OJ L 153, 22.5.20 14, p. 62.).

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.  
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(2) 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.   
                                                 
2 Recommendation ITU -R M. 1652 -1, "Dynamic frequency selection in wireless access systems including radio 
local area networks for the purpose of protecting the radiodetermination service in the 5 GHz band " EN 3  EN Parameter  Technical conditions  
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 s 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.  
 
Techniques to access spectrum and miti gate 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 hav e 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.
