31、tion 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. Radar detection (DFS) is not required in the frequency range 5 850 MHz to 5 8
32、75 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 shal
33、l perform a Channel Availability Check (see clause 4.6.2.1) 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
34、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
35、period is referred to as the Non-Occupancy Period (see clause 4.6.2.4); 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.

37、 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 Peri

At each power-up, the device is assumed to have no Available Channels. 4.6.2.1.2 Limit The Channel Availability Check
39、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 tables D.3
40、.1 and D.3.2 with a level above the Interference Detection Threshold defined in table D.2.

The Channel Revalidation Period for Available Channels remains valid for a maximum period a
41、s defined in table D.1. 4.6.2.1.3 Conformance Conformance tests for this requirement are defined in clause 5.3.6. 4.6.2.2 In-Service Monitoring 4.6.2.2.1 Definition The In-Service Monitoring is defined as the process by which a device monitors the Operating Channel for the presence of radar signals.
42、 4.6.2.2.2 Limit The In-Service Monitoring shall be used to continuously monitor an Operating Channel. The In-Service-Monitoring shall start immediately after the device has started transmissions on an Operating Channel. During the In-Service Monitoring, the device shall be capable of detecting any
43、of the radar signals that fall within the range given by tables D.3.1 and D.3.2 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 tables D.3.1 and D.3.2. 4.6.2.2.3 Conformance Co

ETSI ETSI EN 302 502 V1.2.1 (2008-07) 164.6.2.3 Channel Shutdown 4.6.2.3.1 Definition The Channel Shutdown is defined as the process initiated by the equipment immediately after a radar signal has been detected on an Operating Channel
45、. The equipment shall stop transmitting on this channel, which it shall do within the Channel Move Time. The aggregate duration of all transmissions of the equipment on this channel during the Channel Move Time shall be limited to the Channel Closing Transmission Time. The aggregate duration of all
46、transmissions shall not include quiet periods in between transmissions. 4.6.2.3.2 Limit The Channel Shutdown process shall start immediately after a radar signal has been detected.

48、er a radar signal was detected on that channel by either the Channel Availability Check or the In-Service Monitoring. NOTE: A new Channel Availability Check is required before the channel can be identified again as an Available Channel. 4.6.2.4.2 Limit The Non-Occupancy Period shall not be less than
49、 the value defined in table D.1. 4.6.2.4.3 Conformance Conformance tests for this requirement are defined in clause 5.3.6. 5 Testing for compliance with technical requirements 5.1 Conditions of Testing 5.1.1 Environmental specifications Unless otherwise stated in the test procedures for essential radio test suites (see clause 5.3), the tests defined in the present document shall be carried out at representative points within the boundary limits of the declared operational environmental profile (see clause 5.3.1).
