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 EIRP of
less than 500 mW.


Maximum EIRP of this device is 208.803mW which less than 500mW, therefore it’s no require TPC
function.


2.7   STATEMENT OF MANUFACTURER

This device (Client) is without radar detection, then the 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.

 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.

 Note 1: Channel Move Time and the Channel Closing Transmission Time should be performed
 with Radar Type 0. The measurement timing begins at the end of the Radar Type 0 burst.
 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 0 should be used. For
 each frequency step the minimum percentage of detection is 90 percent. Measurements are
 performed with no data traffic.

Channel Loading
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 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 5500 MHz in 20MHz Bandwidth, 5510MHz in 40MHz Bandwidth and
5530 MHz in 80MHz Bandwidth. 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 3.428dBi
and required detection threshold is -59.572dBm (= -64 +1 +3.428). The calibrated conducted
detection threshold level is set to -59.572 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;
5) An analyzer plot that contains a single 30-minute sweep on the original test frequency.
