10.2 Parameters of DFS test signals

10.2.1 DFS Detection Thresholds for Master Devices as well as Client Devices With
Radar Detection

Value
Maximum Transmit Power EIRP
(see note)

≥ 200 mW -64 dBm

< 200 mW and
-62 dBm
power spectral density < 10 dBm/MHz
< 200 mW and
-64 dBm
That do not meet the power spectral density < 10 dBm/MHz
Note 1: This is the level at the input of the receiver assuming a 0 dBi receive antenna.
Note 2: Throughout these test procedures an additional 1 dB has been added to the amplitude of the test
transmission waveforms to account for variations in measurement equipment. This will ensure that the test
signal is at or above the detection threshold level to trigger a DFS response.
Note3: EIRP is based on the highest antenna gain. For MIMO devices refer to KDB Publication 662911
D01.

power bandwidth. See Note 3.

Note 1: Channel Move Time and the Channel Closing Transmission Time should be performed with Radar
Type 0. The measurement timing begins at the end of the Radar Type 0 burst.
Note 2: The Channel Closing Transmission Time is comprised of 200 milliseconds starting at the beginning
of the Channel Move Time plus any additional intermittent control signals required to facilitate a
Channel move (an aggregate of 60 milliseconds) during the remainder of the 10 second period.
The aggregate duration of control signals will not count quiet periods in between transmissions.
Note 3: During the U-NII Detection Bandwidth detection test, radar type 0 should be used. For each
frequency step the minimum percentage of detection is 90 percent. Measurements are performed
with no data traffic.

For the Frequency Hopping Radar Type, the same Burst parameters are used for each waveform. The hopping
sequence is different for each waveform and a 100-length segment is selected from the hopping sequence
defined.
The first frequency in a hopping sequence is selected randomly from the group of 475 integer frequencies from
5250 – 5724 MHz. Next, the frequency that was just chosen is removed from the group and a frequency is
randomly selected from the remaining 474 frequencies in the group. This process continues until all 475
frequencies are chosen for the set.

10.3.2 Radar burst timing signal
To accurately determine the channel closing time and channel closing transmission time the spectrum analyser
is triggered at the end of the radar burst (see marker at t = 0ms).

10.4 Test results (prior to use of a channel)

10.4.1 Non-Occupancy Period
A channel that has been flagged as containing a radar system, either by a channel availability check or in-
service monitoring, is subject to a non-occupancy period of at least 30 minutes. The non occupancy period
starts at the time when the radar system is detected.

10.5 Test results (during normal operation)

10.5.1 Channel move time / channel closing transmission time
After a radar’s presence is detected, all transmissions shall cease on the operating channel within 10 seconds.
Transmissions during this period shall consist of normal traffic for a maximum of 200 ms after detection of the
radar signal. In addition, intermittent management and control signals can be sent during the remaining time to
facilitate vacating the operating channel not exceeding 60ms.

The test is performed during normal operation with the highest bandwidth supported by the DUT.

Note: With Marker 1 at the end of the radar pulse (t = 0ms) the Channel Closing Time is determined by setting
a Delta-Marker to the point where the last transmission occurred.

The Channel Closing Time is 4.04 seconds.

Note: The accumulated transmission time is calculated by the number of bins occurring after t = 0ms
multiplied with the Time-per-sweep point-factor resulting from the Sweep Time and number of Sweep
Points of the Spectrum Analyzer.

The Channel Closing Transmission Time is 43.5 milliseconds.
