3.0        ANTENNA REQUIREMENTS

Excerpt from §15.203 of the FCC Rules/Regulations:
“An intentional radiator antenna shall be designed to ensure that no antenna other than that furnished by the
responsible party can be used with the device. The use of a permanently attached antenna or of an antenna that
uses a unique coupling to the intentional radiator shall be considered sufficient to comply with the provisions of this
section.”

  •      The antennas of the EUT are permanently attached.

  •      There are no provisions for connection to an external antenna.

Conclusion:
The EUT complies with the requirement of §15.203.

5.2          Requirements
Per KDB 905462 D02 v02 the following are the requirements for Client Devices:

a) A Client Device will not transmit before having received appropriate control signals from a Master Device.
b) A Client Device will stop all its transmissions whenever instructed by a Master Device to which it is associated
   and will meet the Channel Move Time and Channel Closing Transmission Time requirements. The Client Device
   will not resume any transmissions until it has again received control signals from a Master Device.
c) If a Client Device is performing In-Service Monitoring and detects a Radar Waveform above the DFS Detection
    Threshold, it will inform the Master Device. This is equivalent to the Master Device detecting the Radar
    Waveform and d) through f) of section 5.1.1 apply.
d) Irrespective of Client Device or Master Device detection the Channel Move Time and Channel Closing
   Transmission Time requirements remain the same.
e) The client test frequency must be 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 shutdown (rather than moving channels), no beacons should appear.


Channel Move Time and Channel Closing Transmission Time requirements are listed in the following table.

Parameter                                                                                                           Value

Channel Availability Check Time                                                                                     60 seconds

                                                                                                                    See Note 1.
Channel Closing Transmission Time                                                                                   200 milliseconds + an

                                                                                                                    remaining 10 second period.
                                                                                                                    See Notes 1 and 2.

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.

The DFS detection thresholds are defined for Master devices and Client Devices with In-service monitoring. These
detection thresholds are listed in the following table.

      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.

5.5          Parameters of DFS Test Signals
As the EUT is a Client Device with no Radar Detection only one type radar pulse is required for the testing. Radar
Pulse type 1 was used in the evaluation of the Client device for the purpose of measuring the Channel Move Time
and the Channel Closing Transmission Time. Table 5-7 lists the parameters for the Short Pulse Radar Waveforms.
A plot of the Radar Pulse Type 1 used for testing is included in Section 5.7 of this report.

                                          Conducted DFS Test Setup

KDB 905462 D02 v02 describes a radiated test setup and a conducted test setup. The conducted test setup was
used for this testing. Figure 5-1 shows the typical test setup. In Band 2C, one channel selected between 5500
and 5720 MHz was chosen for testing.

      1. The “Aeroflex PXI DFS Radar Simulator and Analyzer Test Suite” is setup to provide a simulated radar
         pulse at the frequency that the Master and Client are operating. A Type 0 radar pulse was used.
      2. The Client Device (EUT) is set up per the diagram in Figure 5-1 and communications between the Master
         device and the Client is established.
      3. An MPEG or data file that is typical for the device is streamed from the Master to the Client to properly load
         the network.
      4. The “Aeroflex PXI DFS Radar Simulator and Analyzer Test Suite” is set to record and display 12 seconds
         of time, starting from where the simulated radar is generated. This time domain plot captures any
         transmissions occurring up to and after 10sec. Aggregate time is computed to ensure compliance. (Note:
         the channel may be different since the Master and Client have changed channels due to the detection of
         the initial radar pulse.)
      5. After the initial radar burst the channel is monitored for 10 minutes to ensure no transmissions or beacons
         occur. A second monitoring setup is used to verify that the Master and Client have both moved to different
         channels.

5.7           System Calibration:
The following equipment setup was used to calibrate the Radar Waveform. A spectrum analyzer was used to
establish the test signal level for each radar type. During this process, there were no transmissions by either the
Master or Client Device. The spectrum analyzer was switched to the zero span (Time Domain) mode at the
frequency of the Radar Waveform generator. Peak detection was utilized. The spectrum analyzer resolution
bandwidth (RBW) and video bandwidth (VBW) were set to 3 MHz.

The signal generator amplitude is adjusted so that the power level measured at the spectrum analyzer is equal to
the DFS detection threshold -64 dBm. The required conducted threshold at the antenna port is -64dBm + EUT
Antenna Gain (dBi) + 1dB = -63 dBm (Section 7.2).

6.0      EUT TEST SETUP


  Client is connected to Master (AP) via WLAN network and plays a video test file “6 ½ Magic Hours” in a Server
  (Laptop). This Server is connected to the Master (AP) via ethernet cable. The Vivaldi antenna is adjusted so that
  the WLAN traffic level, as displayed on the spectrum analyzer, is at lower amplitude than the radar detection
  threshold.

7.2          Channel Loading
Channel Loading Notes:
Per KDB 905462 D02 v02, timing plots are required with calculations demonstrating a minimum channel loading
of approximately 17% or greater. For example, you can zero span the spectrum analyzer and approximate the
transmission time.




                                                                      Figure 7-1. Band 2C Period

                                  Channel Loading = Pulse Width / Period = 104.4 µs / 175.2 µs = 59.59 %
