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.

duration of control signals will not count quiet periods in between transmissions.

Three subsets of trials will be performed with a minimum of ten trials per subset. The subset of trials differ in
where the Long Pulse Type 5 Signal is tuned in frequency.

a) the Channel center frequency
b) tuned frequencies such that 90% of the Long Pulse Type 5 frequency modulation is within the low edge
of the UUT Occupied Bandwidth
c) tuned frequencies such that 90% of the Long Pulse Type 5 frequency modulation is within the high edge
of the UUT Occupied Bandwidth

It include 10 trails for every subset, the formula as below,

For subset case 1: the center frequency of the signal generator will remain fixed at the center of the UUT
Channel.

For subset case 2: to retain 90% frequency overlap between the radar signal and the UUT Occupied
Bandwidth, the center frequency of the signal generator will vary for each of the ten trials in subset case 2.
The center frequency of the signal generator for each trial is calculated by:

  +(0.4∗                [            ])

For subset case 3: to retain 90% frequency overlap between the radar signal and the UUT Occupied
Bandwidth, the center frequency of the signal generator will vary for each of the ten trials in subset case 3.
The center frequency of the signal generator for each trial is calculated by:

   −(0.4∗               [            ])

5       Test Procedure
5.1      DFS Measurement System
A complete 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 10, 11 and 12. The traffic monitoring subsystem is specified to the type of unit under test
(UUT).

System testing will be performed with channel-loading using means appropriate to the data types that are
used by the unlicensed device. The following requirements apply:
          a) The data file must be of a type that is typical for the device (i.e., MPEG-2, MPEG-4, WAV, MP3,
          MP4, AVI, etc.) and must generally be transmitting in a streaming mode.
          b) Software to ping the client is permitted to simulate data transfer but must have random ping
          intervals.
          c) Timing plots are required with calculations demonstrating a minimum channel loading of
    V
          approximately 17% or greater.
          d) Unicast or Multicast protocols are preferable but other protocols may be used. The appropriate
          protocol used must be described in the test procedures.

5.2     Calibration of DFS Detection Threshold Level
The measured channel is 5500MHz, 5510MHz and 5530MHz. The radar signal was the same as transmitted
channels, and injected into the antenna of AP (master) or Client Device with Radar Detection, measured the
channel closing transmission time and channel move time. The calibrated conducted detection threshold
level is set to -64dBm. The tested level is lower than required level hence it provides margin to the limit.

6.2.3   Non-Occupancy Period
Associate test:

During the 30 minutes observation time, UUT did not make any transmissions on a channel after a radar
signal was detected on that channel by either the Channel Availability Check or the In-Service Monitoring.

1) EUT (Client) links with master on 5500MHz.
                                    Waveform of EUT links up with Master




2) Client plays specified files via master.
