                                         TEST CONDITIONS


Power supply (V):
        Vnominal = 3.3 Vdc
Type of power supply = DC voltage from HMC/NGFC test board.
Type of antenna = External attachable PIFA antenna.
Declared Gain for antenna = 5 dBi


The test set-up was made in accordance to the general provisions of Compliance measurement
procedures for unlicensed-national information infrastructure devices operating in the 5.25-5.35GHz and
5.47-5.725GHz Bands incorporating Dynamic Frequency Selection (FCC Order, ET Docket No.03-122
(FCC 06-96).
For radio testing purposes the EUT card was installed in a test fixture. The test fixture is connected to a
laptop computer and dc power supplied. During the test a streaming video file (MPEG) is sent from the
master device (connected to a server via an Ethernet interface) to the laptop computer.
The PC was using the Intel test SW: Intel Pro Set V16.

The manufacturer declared values for the EUT operational characteristics that affect DFS are as follows:

    -     Client Device with no DFS (no In Service Monitoring, no Ad-Hoc mode).
    -     Maximum declared antenna gain (dBi) for 5.25-5.35 GHz & 5.47-5.725 GHZ is 5dBi.



DFS Measurement instrumentation

A Pulse function generator HP8116A and an Agilent E4438C Vector signal generator are used as the
radar-generating source. The waveform of pulses and burst configuration are programmed using the
Pulse function generator and the Vector signal generator is used for up-converting the signal to the 5
GHz band.

The output of the Vector signal generator is connected to a calibrated horn antenna.

Channel monitoring is implemented by using a spectrum analyzer and digital storage oscilloscope. The
analyzer is configured in a zero-span mode, center frequency set to the radar waveform´s frecuency or the
center frequency of the EUT´s operating channel.
The IF output of the spectrum analyzer is connected to one input of the oscilloscope. The output of the
Pulse function generator is used to send the modulating signal. This output is also connected to a second
input on the oscilloscope and the oscilloscope display both the RF channel traffic and the radar pulses on
its display.




Report Nº(NIE): 38067RRF.004                    Page 10 of 16                                  2013-03-06


The master and slave (EUT) devices are placed inside an anechoic chamber. The simulated radar
waveform is transmitted using a directional calibrated horn antenna toward the unit performing the radar
detection (master).

The radar signal level at the master device is verified by measuring the continuous signal level from the
Vector signal generator using a reference measuring antenna placed at the master’s location and
connected to a spectrum analyzer. The signal level is calculated from the measured level at the reference
antenna and taking into account the cable loss and reference antenna gain.

Applied level (dBm) = M (dBm) – Gref (dBi)+ L (dB)

Where:

M (dBm): Measured level in the spectrum analyzer

Gref (dBi): Reference antenna gain

L (dB): Loss of connecting cable between antenna and spectrum analyzer.

The antenna connected to the channel monitoring system is positioned to allow both master and slave
(EUT) transmissions to be observed, with the level of the EUT’s transmissions between at least 10 dB
higher than those from the master device.


The setup is shown in the next figure.

DFS Channel Closing Transmission Time and Channel Move Time measurement method

These times are measured by applying a burst of radar signal and observing the transmissions in the
operating channel. The time between the end of the applied radar burst and the end of transmissions on
the channel is the Channel Move Time.

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.

DFS Channel Non Occupancy Period measurement method

The channel is monitored for 30 minutes to check that there are no transmissions on the channel over the
required non-occupancy period. This is achieved by allowing the analyzer to perform a sweep over a 30
minutes period to capture any transmissions on the channel after the detection of the radar waveform.

The steps below define the procedure to determine the above mentioned parameters when a radar Burst
with a level equal to the DFS Detection Threshold + 1dB is generated on the Operating Channel of the
U-NII device.

Operating Frequency: 5.68 GHz. Channel 136 BW=20MHz.
