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.

The instant that the Channel Move Time and the Channel Closing Transmission Time begins is as follows:
   • For the Short pulse radar Test Signals this instant is the end of the Burst.
    •    For the Frequency Hopping radar Test Signal, this instant is the end of the last radar burst
         generated.
    • For the Long Pulse radar Test Signal this instant is the end of the 12 second period
         defining the radar transmission.
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 channel changes (an aggregate of approximately 60 milliseconds) during the remainder
of the 10 second period. The aggregate duration of control signals will not count quiet periods in
between transmissions.

        7.1.2. DESCRIPTION OF EUT
OVERVIEW OF EUT WITH RESPECT TO §15.407 (h) REQUIREMENTS

The EUT operates over the 5250-5350 MHz band.

The EUT is a Client Device that does not have radar detection capability. The FCC identifier for the
Master Device used with it for DFS testing is LDK102056.

The 4965AGN includes 2 transmitter and 3 receiver chains, to allow 2x3 MIMO. The maximum antenna
gain of the antenna assembly is –0.67 in the 5250-5350 MHz band. The highest power level is 15.8 dBm
EIRP.

TPC is not required since the maximum EIRP is less than 500 mW (27 dBm).

Both of the 50-ohm Tx/Rx antenna ports are connected to the test system via a power combiner/divider to
perform conducted tests.

WLAN traffic is generated by streaming the video file TestFile.mp2 “6 ½ Magic Hours” from the Master
to the Slave in full motion video mode using the media player with the V2.61 Codec package.

The EUT utilizes an 802.11a / 802.11 Draft n IP based architecture. Two nominal channel bandwidths, 20
MHz and 40 MHz, are implemented.


OVERVIEW OF MASTER DEVICE WITH RESPECT TO §15.407 (h) REQUIREMENTS

The Master Device is a Cisco Aironet 1200 AG Series Access Point, FCC ID: LDK102056.

The rated output power of the Master unit is > 23dBm (EIRP). Therefore the required interference
threshold level is –64 dBm.

The calibrated conducted DFS Detection Threshold level is set to –64 dBm.

        7.1.3. TEST AND MEASUREMENT SYSTEM
SYSTEM OVERVIEW

The measurement system is based on a conducted test method.

The short pulse and long pulse signal generating system utilizes the NTIA software and the same
manufacturer / model Vector Signal Generator as the NTIA. The hopping signal generating system
utilizes the simulated hopping method.

The software selects waveform parameters from within the bounds of the signal type on a random basis
using uniform distribution. The short pulse types 2, 3 and 4, and the long pulse type 5 parameters are
randomized at run-time. The hopping type 6 pulse parameters are fixed while the hopping sequence is
based on the August 2005 NTIA Hopping Frequency List, with the initial starting point randomized at
run-time.

The signal monitoring equipment consists of a spectrum analyzer with the capacity to display 8192 bins
on the horizontal axis. A time-domain resolution of 2 msec / bin is achievable with a 16 second sweep
time, meeting the 10 second short pulse reporting criteria. The aggregate ON time is calculated by
multiplying the number of bins above a threshold during a particular observation period by the dwell time
per bin, with the analyzer set to peak detection and max hold. A time-domain resolution of 3 msec / bin is
achievable with a 24 second sweep time, meeting the 22 second long pulse reporting criteria and allowing
a minimum of 10 seconds after the end of the long pulse waveform.


FREQUENCY HOPPING SIGNAL GENERATION

The hopping burst generator is a High Speed Digital I/O card plugged into the control computer. This
card utilizes an independent hardware clock reference therefore the output pulse timing is unaffected by
host computer operating system latency times.

The software selects the hopping sequence as a 100-length segment of the August 2005 NTIA hopping
frequency list. This list contains 274 unique pseudorandom sequences. Each such sequence contains 475
frequencies ordered on a random without replacement basis. Each successive trial uses a contiguous 100-
length segment from within each successive 475-length sequence in the list. The initial starting point
within the list is randomized at run-time such that the first 100-length segment is entirely contained
within the first 475-length sequence. The starting point of each successive trial is incremented by 475.

Each frequency in the 100-length segment is compared to the boundaries of the EUT Detection
Bandwidth and the software creates a hopping burst pattern in accordance with Section 7.4.1.3 Method #2
Simulated Freqeuncy Hopping Radar Waveform Generating Subsystem of FCC 06-96 APPENDIX. The
frequency of the signal generator is incremented in 1 MHz steps from FL to FH for each successive trial.
This incremental sequence is repeated as required to generate a minimum of 30 total trials and to maintain
a uniform frequency distribution over the entire Detection Bandwidth.

MEASUREMENT SYSTEM FREQUENCY REFERENCE

Lock the signal generator and the spectrum analyer to the same reference source as follows: Connect the
10 MHz OUT (SWITCHED) on the spectrum analyer to the 10 MHz IN on the signal generator and set
the spectrum analyzer 10 MHz Out to On.


SYSTEM CALIBRATION

Adjust the Master Step Attenuator to 30 dB, the Link Step Attenuator to 70 dB, and the Slave Step
Attenuator to 70 dB.

If required, disconnect the spectrum analyzer, Master Device, and Slave Device from the test system.
Terminate the Common port of the Spectrum Analyzer Combiner/Divider, Port 2 of the Master Diversity
Combiner/Divider, and Ports 1 and 2 of the Slave Diversity Combiner/Divider. Leave, or connect, the
appropriate cable to Port 1 of the Master Diversity Combiner/Divider and connect the free end (Master
Device end) of this cable to the spectrum analyzer.

Adjust the signal generator and spectrum analyzer to the center frequency of the channel to be measured.
Set the signal generator to CW mode. Set the RBW of the spectrum analyzer to 10 kHz and the span to
100 kHz. Adjust the amplitude of the signal generator to yield a measured level of –64 dBm on the
spectrum analyzer.

Without changing any of the instrument settings, reconnect the spectrum analyer to the Common port of
the Spectrum Analyzer Combiner/Divider, then remove the cable from Port 1 of the Master Diversity
Combiner/Divider and replace this cable with a termination. Measure the amplitude and calculate the
difference from –64 dBm. Adjust the Reference Level Offset of the spectrum analyzer to this difference.
Confirm that the signal is displayed at –64 dBm. Readjust the RBW and VBW to 3 MHz, set the span to
10 MHz, and confirm that the signal is still displayed at –64 dBm.

This Reference Level Offset setting is used for all tests for which the Master Step Attenuator is set to 30
dB. The spectrum analyzer displays the level of the signal generator as received at the antenna ports of the
Master Device. The interference detection threshold may be varied from the calibrated value of –64 dBm
and the spectrum analyzer will still indicate the level as received by the Master Device.

The Link Step Attenuator and Slave Step Attenuator settings may be changed without affecting the
System Calibration. The System Calibration process must be repeated for different settings of the Master
Step Attenuator to determine the Reference Level Offset associated with each Master Step Attenuator
setting.

INTERFERENCE DETECTION THRESHOLD ADJUSTMENT

Set the signal generator to produce the specified radar waveform, trigger a burst manually and measure
the amplitude on the spectrum analyzer. Readjust the amplitude of the signal generator as required so that
the peak level of the waveform is at a displayed level equal to the required or desired interference
detection threshold.


ADJUSTMENT OF DISPLAYED TRAFFIC LEVEL

Establish a link between the Master and Slave, adjusting the Link Step Attenuator as needed to provide an
adequate RSS level at the Master and Slave devices. Stream the video test file to generate WLAN traffic.
Adjust the Slave Step Attenuator so that the WLAN traffic level from the Slave, as displayed on the
spectrum analyzer, is at lower amplitude than the radar detection threshold.

Confirm that the displayed traffic is from the Slave Device by changing the setting of the Slave Step
Attenuator and verifying that the displayed traffic level changes accordingly. Confirm that the displayed
traffic does not include Master Device traffic by changing the setting of the Master Step Attenuator and
the Link Step Attenuator and verifying that the displayed traffic level does not change. Reset all Step
Attenuators to their previous settings.

If the above conditions cannot be met, use a different setting of the Master Step Attenuator, performing a
new System Calibration and Interference Detection Threshold Adjustment as required for the new Master
Step Attenuator setting.

        7.1.6. TEST CHANNEL AND METHOD

All tests were performed at a channel center frequency of 5300 MHz utilizing a conducted test method.


        7.1.7. CHANNEL MOVE TIME AND CHANNEL CLOSING TRANSMISSION
             TIME


GENERAL REPORTING NOTES

The reference marker is set at the end of last radar pulse.

The delta marker is set at the end of the last WLAN transmission following the radar pulse. This delta is
the channel move time.

The aggregate channel closing transmission time is calculated as follows:

Aggregate Transmission Time =
(Number of analyzer bins showing transmission) * (dwell time per bin)

The observation period over which the aggregate time is calculated
Begins at (Reference Marker + 200 msec)
and
Ends no earlier than (Reference Marker + 10 sec).
