 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

each of the bonded 20 MHz channels 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∗ 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[            ])

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:

       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 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.
