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.    TPC mechanism is not required for
systems with an EIRP of less than 500 mW.

Maximum EIRP of this device is 620.098mW which more than 500mW, therefore it’s
require TPC function.
The UUT can adjust a transmitter’s output power based on the signal level present at the
receiver.

TPC is controlled by software and the user may adjust the Transmit Power level from web
interface that may adjust the transmit power among Max,-3dB,-6dB, from web manually
when the power needs to be increased or decreased.
The interface is for WLAN purpose that is installed fixedly, so we implement manual TPC
instead of automatic TPC on the product.



2.7 STATEMENT OF MAUNFACTURER

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.

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.

 frequencies in all 20 MHz channel blocks and a null frequencies between the bonded 20
 MHz channel blocks.

 power spectral density requirement
 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.




PARAMETERS OF DFS TEST SIGNALS
Step intervals of 0.1 microsecond for Pulse Width, 1 microsecond for PRI, 1 MHz for chirp
width and 1 for the number of pulses will be utilized for the random determination of
specific test waveforms.

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 5530MHz 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.

6.2.1 TEST MODE: DEVICE OPERATING IN CLIENT WITHOUT RADAR
      DETECTION MODE.

The radar test signals are injected into the Master Device.
This test was investigated for different bandwidth (20MHz、40MHz and 80MHz).
The following plots was done on 80MHz as a representative


6.2.1.1 DFS DETECTION THRESHOLD

6.2.1.3 NON- OCCUPANCY PERIOD

ASSOCIATED TEST

1) Test results demonstrating an associated client link is established with the master on a test
frequency.




EUT (Client ) links with master on 5530MHz



2) The master and DFS-certified client device are associated, and system testing will be performed
with channel-loading using means appropriate to the data types for a non-occupancy period test.




Client plays a specified files via master.

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.
