2.6   Transmit Power Control (TPC)
U-NII 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.

Maximum EIRP of this device is 190.577mW which less than 500mW, therefore it’s not require TPC function.

  Applicable       E.I.R.P                                     FCC 15.407 (h)(1)

                  >500mW     The TPC mechanism is required for system with an E.I.R.P of above 500mW

       √          <500mW     The TPC mechanism is not required for system with an E.I.R.P of less 500mW


2.7   Statement of Maunfacturer
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.

and the channel center frequency.

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∗                [           ])

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).

Radiated Setup Configuration of DFS Measurement System




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 approximately
    V
          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 channels are 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.
