Section 2: Assessment Information
2.1 General
This report contains an assessment of an apparatus against Radio Standards based upon tests carried out on
the samples submitted. The testing was performed by and for the use of Cisco systems Inc.:

With regard to this assessment, the following points should be noted:

a)        The results contained in this report relate only to the items tested and were obtained in the period
          between the date of the initial assessment and the date of issue of the report. Manufactured products
          will not necessarily give identical results due to production and measurement tolerances.
b)        The apparatus was set up and exercised using the configuration and modes of operation defined in
          this report only.
c)        Where relevant, the apparatus was only assessed using the susceptibility criteria defined in this
          report and the Test Assessment Plan (TAP).
d)        All testing was performed under the following environmental conditions:
          Temperature                15°C to 35°C (54°F to 95°F)
          Atmospheric Pressure        860mbar to 1060mbar (25.4" to 31.3")
          Humidity                    10% to 75*%
e)        All AC testing was performed at one or more of the following supply voltages:
           110V 60 Hz (+/-20%)


Units of Measurement

The units of measurements defined in the appendices are reported in specific terms, which are test
dependent. Where radiated measurements are concerned these are defined at a particular distance. Basic
voltage measurements are defined in units of [dBuV]

As an example, the basic calculation for all measurements is as follows:
         Emission level [dBuV] = Indicated voltage level [dBuV] + Cable Loss [dB] + Other correction
factors [dB]

The combinations of correction factors are dependent upon the exact test configurations [see test equipment
lists for further details] and may include:-
          Antenna Factors, Pre Amplifier Gain, LISN Loss, Pulse Limiter Loss and Filter Insertion Loss..
Note: to convert the results from dBuV/m to uV/m use the following formula:-
          Level in uV/m = Common Antilogarithm [(X dBuV/m)/20] = Y uV/m

Appendix A                   Dynamic Frequency Selection (DFS)

                 in the 5250 MHz – 5350 MHz and 5470 MHz – 5725 MHz bands.

A.1    DFS Overview

A UNII network will employ a DFS function to detect signal from radar systems and to avoid
co-channel operation with these systems. This applies to the 5250 MHz – 5350 MHz and/or
5470 MHz – 5725 MHz bands.

Within the context of the operation of the DFS function, a U-NII device will operate in either
Master Mode or Client Mode. U-NII devices operating in the Client Mode can only operate in a
network controlled by a U-NII device operating in Master Mode.

A.2    DFS Technical Requirements

FCC 15.407: 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. A TPC mechanism is not
     required for systems with an e.i.r.p. of less than 500 mW.

       U-NII devices operating in the 5.25-5.35 GHz and 5.47-5.725 GHz bands shall employ a
       DFS radar detection mechanism to detect the presence of radar systems and to avoid
       co-channel operation with radar systems.

    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.
      Note 3: EIRP is based on the highest antenna gain.

A.4 Radar Waveform Calibration

A.4.1 Block Diagram
The following equipment setup was used to calibrate the conducted 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 largest bandwidth available.

      The signal generator amplitude was calibrated so that the power level measured
      approximately at -61.0 dBm.

                      Ch100 (5500 MHz) DFS Detection Thresholds = -61.0 dBm




   The DFS detection thresholds level of -61 dBm at the input of the receiver is assuming a 0 dBi of antenna
   gain during calibration of the test setup. Throughout the test procedures an additional 1 dB has been added to
   the amplitude of the test transmission waveforms to account for variations in the measurement equipment.
   This will ensure that the test signal is at or above the detection threshold level to trigger a DFS response.

A.5 Test Procedures
Ref. KDB 905462 D02 UNII DFS Compliance Procedures New Rules v01r02, section 7.8.3

 1. A spectrum analyzer is used as a monitor to verify that the UUT has vacated the Channel
    within the (Channel Closing Transmission Time and Channel Move Time, and does not
    transmit on a Channel during the Non-Occupancy Period after the detection and Channel
    move.
 2. Following is the test setup used to generate the Radar Waveforms, and for all DFS tests
    described herein.

 3. System test setup was configured with two IP-Phones registered to the Call Manager and
    using the Access Point router for Wi-Fi connection to establish call connection.

 4. UNII Detection Bandwidth: DFS testing was done at 5290 MHz and 5530 MHz in
    802.11ac VHT80. The 99% channel bandwidth for 80MHz signals is 76.0 MHz (See the
    99% BW section of the RF report for further measurement details).

     The generating equipment is configured as shown in the Conducted Test Setup above. A
     single Burst of the desired radar profile is produced at 5290 MHz for UNII-2A band and
     5530MHz for UNII-2C band at a -61dBm level. The UUT is set up as a client device
     associated with the master with traffic during phone call established.

 5. One frequency will be chosen from the Operating Channels of the UUT within the
    5250-5350 MHz or 5470-5725 MHz bands. For 802.11 devices, the test frequency must
    contain control signals. This can be verified by disabling channel loading and monitoring the
    spectrum analyzer. If no control signals are detected, another frequency must be selected
    within the emission bandwidth where control signals are detected.

 6. In case the UUT is a U-NII device operating as a Client Device (with or without DFS), a
    U-NII device operating as a Master Device will be used to allow the UUT (Client device) to
    Associate with the Master Device. In case the UUT is a Master Device, a U-NII device
    operating as a Client Device will be used and it is assumed that the Client will associate with
    the UUT (Master). In both cases for conducted tests, the Radar Waveform generator will be
    connected to the Master Device. For radiated tests, the emissions of the Radar Waveform
    generator will be directed towards the Master Device. If the Master Device has antenna gain,
    the main beam of the antenna will be directed toward the radar emitter. Vertical polarization
    is used for testing.

 7. Stream the channel loading test file from the Master Device to the Client Device on the test
    Channel for the entire period of the test.

 8. At time T0 the Radar Waveform generator sends a Burst of pulses for one of the Short Pulse
    Radar Types 1-4 in Table 3 at levels defined in Table 1, on the Operating Channel. An
    additional 1 dB is added to the radar test signal to ensure it is at or above the DFS Detection
    Threshold, accounting for equipment variations/errors.

 9. Observe the transmissions of the UUT at the end of the radar Burst on the Operating Channel
    for duration greater than 10 seconds. Measure and record the transmissions from the UUT
    during the observation time (Channel Move Time). Measure and record the Channel Move
    Time and Channel Closing Transmission Time if radar detection occurs. Figure 1 illustrates
    Channel Closing Transmission Time.

 10. When operating as a Master Device, monitor the UUT for more than 30 minutes following
     instant T2 to verify that the UUT does not resume any transmissions on this Channel.
     Perform this test once and record the measurement result.

 11. In case the UUT is a U-NII device operating as a Client Device with In-Service Monitoring,
     perform steps a) to f).
