All devices in a FWA deployment shall employ full Dynamic Frequency Selection (DFS) functionality to detect
transmissions from other systems and to avoid co-channel operation with these systems, notably radar systems.
Dynamic Frequency Selection (DFS) is only required in the frequency range 5 725 MHz to 5 850 MHz.
The operational behaviour and DFS requirements for all equipment are as follows:
a) the equipment shall use a Radar Interference Detection function in order to detect radar signals;
b) before transmitting on a channel, which has not been identified as an Available Channel, the equipment shall
perform a Channel Availability Check (see clause 4.2.6.2.1) to ensure that there is no radar operating on the
channel;
c) during normal operation, the equipment shall monitor the Operating Channel (In-Service Monitoring) to ensure
that there is no radar operating on the channel;
d) if the equipment has detected a radar signal during In-Service Monitoring, the Channel Shutdown shall be
initiated and the Operating Channel becomes an Unavailable Channel;
e) the equipment shall not resume any transmissions on this Unavailable Channel during a period of time after a
radar signal was detected. This period is referred to as the Non-Occupancy Period (see clause 4.2.6.2.4);
f) after the end of a Non-Occupancy Period, a Channel Availability Check is required before an Unavailable
Channel can be identified as an Available Channel again;
g) a channel can only have one status at any specific time.
4.2.6.2 DFS Technical requirements specifications

4.2.6.2.1.1 Definition
The Channel Availability Check is defined as the mechanism by which a device checks a channel for the presence of
radar signals.
ETSI
14 ETSI EN 302 502 V2.1.1 (2017-03)
There shall be no transmissions by the device within the channel being checked during this process.
If no radars have been detected by this mechanism, the channel becomes an Available Channel.
Following a channel availability check during which no radars were detected, the Channel Revalidation Period is
defined as the period of time during which a channel identified as an Available Channel remains valid as such.
The device shall only start transmissions on Available Channels.
At each power-up, the device is assumed to have no Available Channels.
4.2.6.2.1.2 Limit
The Channel Availability Check shall be performed during a continuous period in time (Channel Availability Check
Time) which shall not be less than the value defined in table D.1.
During the Channel Availability Check, the device shall be capable of detecting any of the radar signals that fall within
the range given by table D.3 a) and table D.3 b) with a level above the Interference Detection Threshold defined in
table D.2.
The detection probability for a given radar signal shall be greater than the value defined in table D.3 a) and table D.3 b).
The Channel Revalidation Period for Available Channels remains valid for a maximum period as defined in table D.1.
4.2.6.2.1.3 Conformance
Conformance tests for this requirement are defined in clause 5.4.6.
4.2.6.2.2 In-Service Monitoring

Dynamic Frequency Selection (DFS) is only required in the frequency range 5 725 MHz to 5 850 MHz. The operational behaviour and DFS requirements for all equipment are as follows: a) the equipment shall use a Radar Interference Detection function in order to detect radar signals; b) before transmitting on a channel, which has not been identified as an Available Channel, the equipment shall perform a Channel Availability Check (see clause 4.2.6.2.1) to ensure that there is no radar operating on the channel; c) during normal operation, the equipment shall monitor the Operating Channel (In-Service Monitoring) to ensure that there is no radar operating on the channel; d) if the equipment has detected a radar signal during In-Service Monitoring, the Channel Shutdown shall be initiated and the Operating Channel becomes an Unavailable Channel; e) the equipment shall not resume any transmissions on this Unavailable Channel during a period of time after a radar signal was detected. This period is referred to as the Non-Occupancy Period (see clause 4.2.6.2.4); f) after the end of a Non-Occupancy Period, a Channel Availability Check is required before an Unavailable Channel can be identified as an Available Channel again; g) a channel can only have one status at any specific time. 4.2.6.2 DFS Technical requirements specifications 4.2.6.2.1 Channel availability check and channel revalidation period 4.2.6.2.1.1 Definition The Channel Availability Check is defined as the mechanism by which a device checks a channel for the presence of radar signals.

If no radars have been detected by this mechanism, the channel becomes an Available Channel. Following a channel availability check during which no radars were detected, the Channel Revalidation Period is defined as the period of time during which a channel identified as an Available Channel remains valid as such. The device shall only start transmissions on Available Channels. At each power-up, the device is assumed to have no Available Channels. 4.2.6.2.1.2 Limit The Channel Availability Check shall be performed during a continuous period in time (Channel Availability Check Time) which shall not be less than the value defined in table D.1.
