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.



                           Table 9: DFS Response Requirement Values

                     Parameter                                           Value

                                                  milliseconds over remaining 10 second period.
                                                  See Notes 1 and 2.

                                                  power bandwidth.
                                                   See Note 3.
Note 1: The instant that the Channel Move Time and the Channel Closing Transmission Time
begins is as follows:
• For the Short Pulse Radar Test Signals this instant is the end of the Burst.
• For the Frequency Hopping radar Test Signal, this instant is the end of the last radar
Burst generated.
• For the Long Pulse Radar Test Signal this instant is the end of the 12 second period defining the
Radar Waveform.
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 1 is used and for each
frequency step the minimum percentage of detection is 90 percent. Measurements are performed
with no data traffic.

5. TEST PROCEDURE

5.1     ADT DFS MEASUREMENT SYSTEM:
A complete ADT DFS Measurement System consists of two subsystems: (1) the Radar
Signal Generating Subsystem and (2) the Traffic Monitoring Subsystem. The control PC is
necessary for generating the Radar waveforms in Table 6, 7 and 8. The traffic monitoring
subsystem is specified to the type of unit under test (UUT).

The test transmission will always be from the Master Device to the Client Device. While the Client
device is set up to associate with the Master device and play the MPEG file (6 y Magic Hours) from
Master device, the designated MPEG test file and instructions are located at:

5.2      CALIBRATION OF DFS DETECTION THRESHOLD LEVEL:
The measured channel is 5500MHz. The radar signal was the same as transmitted
channels, and injected into the antenna port of AP (master) or Client Device with Radar
Detection, measured the channel closing transmission time and channel move time. The
Master antenna gain is 3dBi and required detection threshold is -58dBm (= -62 +1+3)dBm.
The calibrated conducted detection threshold level is set to -59dBm. The tested level is
lower than required level hence it provides margin to the limit.
