‘ANNEX
Harmonised technical conditions for WAS/RLANs in the 5 945–6 425 MHz frequency band
Table 1
Low power indoor (‘LPI’) WAS/RLAN devices
Parameter
Technical conditions
Permissible operation
Restricted to indoor use, including in trains with metal-coated windows (note 1) and aircraft.
Outdoor use, including in road vehicles, is not permitted.
Category of device
An LPI access point or bridge that is supplied with power from a wired connection has an integrated antenna (note 2) and is not battery powered.
An LPI client device that is connected to an LPI access point or another LPI client device and may or may not be battery powered.
Frequency band
5 945 –6 425 MHz
Maximum mean equivalent isotropically radiated power (‘e.i.r.p.’) for in-band emissions (note 3)
23 dBm
Maximum mean e.i.r.p. density for in-band emissions (note 3)
10 dBm/MHz
Maximum mean e.i.r.p. density for out-of-band emissions below 5 935 MHz (note 3)
– 22 dBm/MHz
Note 1:
Or similar structures made of material with comparable attenuation characteristics.
Note 2:
Or a distributed antenna system installed inside a train or an aircraft.
Note 3:
The mean e.i.r.p. refers to the e.i.r.p. during the transmission burst which corresponds to the highest power, if power control is implemented.
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.

Very Low Power (VLP) WAS/RLAN devices
Parameter
Technical conditions
Permissible operation
Indoors and outdoors.
Use on Unmanned Aircraft Systems (UAS) is not permitted.
Category of device
The VLP device is a portable device.
Frequency band
5 945 –6 425 MHz
Maximum mean e.i.r.p. for in-band emissions (note 1)
14 dBm
Maximum mean e.i.r.p. density for in-band emissions (note 1)
1 dBm/MHz
Narrowband usage maximum mean e.i.r.p. density for in-band emissions (note 1) (note 2)
10 dBm/MHz
Maximum mean e.i.r.p. density for out-of-band emissions below 5 935 MHz (note 1)
– 37 dBm/MHz (note 3)
Note 1:
The mean e.i.r.p. refers to the e.i.r.p. during the transmission burst which corresponds to the highest power, if power control is implemented.
Note 2:
Narrowband (‘NB’) devices are devices that operate in channel bandwidths below 20 MHz. NB devices also require a frequency hopping mechanism based on at least 15 hop channels to operate at a value of in-band power spectral density (‘PSD’) above 1 dBm/MHz.
Note 3:
VLP devices shall first attempt to select a frequency block above 6 105 MHz when initiating a communication session. Alternatively, where no such frequency selection mechanism is implemented, a maximum mean e.i.r.p. density for out-of-band emissions of – 45 dBm/MHz below 5 935 MHz applies.
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.
