DETECTION THRESHOLD VALUES
   TABLE 8: DFS DETECTION THRESHOLDS FOR MASTER DEVICES AND CLIENT

        MAXIMUM TRANSMIT POWER                             VALUE (SEE Note 1 and 2)

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.

                                                 milliseconds over remaining 10 second period.
                                                 See Notes 1 and 2.
U-NII Detection Bandwidth                        Minimum 80% of the UNII 99% transmission
                                                 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 5_GHz_Audio_Test_file.wav from
Master device, the designated wav test file and instructions are located at:
http://ntiacsd.ntia.doc.gov/dfs/.

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 2dBi and required detection
threshold is -60dBm (= -62+2)dBm. The calibrated conducted detection threshold
level is set to -60dBm. The tested level is lower than required level hence it
provides margin to the limit.
