2. DFS (Dynamic Frequency Selection)

2.1. System Overview

2.1.1. Set up of EUT

The radar signal generation equipment consists of a vector signal generator
The signal monitoring equipment consists of a spectrum analyzer set to display 8 001 bins on the horizontal axis. The time domain resolution is 2 msec/bin 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.
The Slave is tested separately for compliance with the Channel Shutdown requirements, for the situation when the Slave device vacates the channel in response to detection of a radar by the Master.
All tests were performed at a channel center frequency of 5 290  and 5 530 . Measurements were
performed using conducted test methods.

Note: Frequencies selected for statistical performance check (Section 7.8.4) should include several frequencies within the radar detection bandwidth and frequencies near the edge of the radar detection bandwidth. For 802.11 devices it is suggested to select frequencies in each of the bonded

20  channels and the channel center frequency.

Note 1: This is the level at the input of the receiver assuming a 0  i receive antenna.

Note 2: Throughout these test procedures an additional 1  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. For MIMO devices refer to KDB Publication 662911 D01.

KDB 905462 D02 Client without DFS New Rules v01r02: UNII client devices without radar detection
· The guidance provided in Section 8 (DFS Test Report Guidelines) in the appropriate DFS Test Procedure
specified in KDB Publication 905462 D02.
· Test results demonstrating an associated client link is established with the master on a test frequency; if a client device operates in a "listen only" mode to a master without formally "associating" with it the test report must include tests for such modes. · The devices must be tested with a master device operating in the same band and operation modes. · If two client devices can communicate directly with each other while maintaining an association with a master or if the client operates on a frequency band while "listening" to a master, such modes must be tested with the master device active. · The client and DFS-certified master device are associated, and a movie can be streamed as specified in the DFS Order for a non-occupancy period test. · The test frequency has been 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 shut down (rather than moving channels), no beacons should appear. · An analyzer plot that contains a single 30-minute sweep on the original channel.

KDB 905462 D02 DFS Compliance Procedures New Rules v02 (7.7 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:
a) The data file must be of a type that is typical for the device (i.e., MPEG-2, MPEG-4, WAV, MP3, MP4, AVI, etc.) and must generally be transmitting in a streaming mode.
b) Software to ping the client is permitted to simulate data transfer but must have random ping intervals.
c) Timing plots are required with calculations demonstrating a minimum channel loading of approximately 17% or greater. For example, channel loading can be estimated by setting the spectrum analyzer for zero span and approximate the Time On/ (Time On + Off Time). This can be done with any appropriate channel BW and modulation type.
d) Unicast or Multicast protocols are preferable but other protocols may be used. The appropriate protocol used must be described in the test procedures.
2.3. Description of EUT
The EUT operates over the band 2A "5 260  ~ 5 320  (11a/n_HT20, 11ac_VHT20, 11ax_HE20), 5 270  ~ 5 310  (11n_HT40, 11ac_VHT40, 11ax_HE40), 5 290  (11ac_VHT80, 11ax_HE80)" and band 2C "5 500  ~ 5 720  (11a/n_HT20, 11ac_VHT20, 11ax_HE20), 5 510  ~ 5 710  (11n_HT40, 11ac_VHT40, 11ax_HE40), 5 530  ~ 5 690  (11ac_VHT80, 11ax_HE80)" ranges.
The rated output power of the client unit is < 200 milliwatt. Therefore the required interference threshold level is -62  m.

The reference maker is set after 200  from the end of Last radar pulse.

The delta is set at the end of the last WLAN transmission following the radar pulse. This delta is the channel closing transmission time within the 10 sec form the end of Last radar pulse.

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 aggregated time is calculated begins at (delta Maker) and ends no earlier than (Reference Maker +10 sec)
