 2.6        Transmit Power Control (TPC)

U—NIl devices operating in the 5.25—5.35 GHz band and the 5.47—5.725 GHz band shall employ a TPC
mechanism. The U—NII device is required to have the capability to operate at least 6 dB below the mean EIRP
value of 30 dBm. A TPC mechanism is not required for systems with an e.i.r.p. of less than 500 mW.



  Applicable                EIRP                                  FCC 15.407 (h)(1)

The UUT can adjust a transmitter‘s output power based on the signal level present at the receiver.TPC is auto
controlled by software.

 2.7        Statement of Manufacturer

Manufacturer statement confirming that information regarding the parameters of the detected Radar
Waveforms is not available to the end user. And the device doesn‘t have Ad Hoc mode on DFS frequency
band.

3. U-NII DFS Rule Requirements
3.1   Working Modes and Required Test Items
The manufacturer shall state whether the UUT is capable of operating as a Master and/or a Client. If the UUT
is capable of operating in more than one operating mode then each operating mode shall be tested separately.
See tables 6 and 7 for the applicability of DFS requirements for each of the operational modes.

Note: Regarding KDB 905462 D03 Client Without Radar Detection New Rules v01r02 section(b)(5/6),
If the client moves with the master, the device is considered compliant if nothing appears in the client
non-occupancy period test. For devices that shut down (rather than moving channels), no beacons
should appear. An analyzer plot that contains a single 30-minute sweep on the original channel.

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.

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∗ ℎ             ℎ[           ])

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∗ ℎ            ℎ[           ])

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

 5.2     Calibration of DFS Detection Threshold Level

The measured channel is chosen from the operating channels of the UUT within the 5250-5350MHz or
5470-5725MHz and using the widest bandwidth mode available for the link. 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 detection threshold is -63dBm
(= -64 +1). The calibrated conducted detection threshold level is set to -63 dBm.

    3). The device transmits one type of radar as specified in the DFS Order.




    Radar 0 is used to test during DFS testing.


    4) The test frequency has been monitored to ensure no transmission of any type has occurred for 30
    minutes;
    Note: If the client moves with the master, the device is considered compliant if nothing appears in the
    client non-occupancy period test. For devices that shut down (rather than moving channels), no
    beacons should appear;
