2.2 DFS OVERVIEW
A U-NII network will employ a DFS function to detect signals from radar systems and to avoid co-channel
operation with these systems. This applies to the 5250-5350 MHz and/or 5470-5725 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 Client Mode can only operate in a network controlled by a U-NII device
operating in Master Mode.
Tables 1 and 2 shown below summarize the information contained in sections 5.1.1 and 5.1.2
The operational behavior and individual DFS requirements that are associated with these modes are as
follows:
Report No.: FCC17010001A-8
Page 7 of 26
2.3 DFS DETECTION THRESHOLDS
Table 3 below provides the DFS Detection Thresholds for Master Devices as well as Client Devices
incorporating In-Service Monitoring.
2.4 RESPONSE REQUIREMENTS
Table 4 provides the response requirements for Master and Client Devices incorporating DFS.
Report No.: FCC17010001A-8
Page 8 of 26
2.5 RADAR TEST WAVEFORMS
This section provides the parameters for required test waveforms, minimum percentage of successful
detections, and the minimum number of trials that must be used for determining DFS conformance. Step
intervals of 0.1 microsecond for Pulse Width, 1 microsecond for PRI, 1 MHz for chirp width and 1 for the
number of pulses will be utilized for the random determination of specific test waveforms.
2.5.1 Short Pulse Radar Test Waveforms
A minimum of 30 unique waveforms are required for each of the Short Pulse Radar Types 2 through 4. If more
than 30 waveforms are used for Short Pulse Radar Types 2 through 4, then each additional waveform must also be
unique and not repeated from the previous waveforms. If more than 30 waveforms are used for Short Pulse Radar
Type 1, then each additional waveform is generated with Test B and must also be unique and not repeated from the
previous waveforms in Tests A or B.
For example if in Short Pulse Radar Type 1 Test B a PRI of 3066 μsec is selected, the number of pulses would be
Roundup
Report No.: FCC17010001A-8
= Round up {17.2} = 18.
Page 9 of 26
The aggregate is the average of the percentage of successful detections of Short Pulse Radar Types 1-4.
For example, the following table indicates how to compute the aggregate of percentage of successful
detections.
Report No.: FCC17010001A-8
Page 10 of 26
2.6 Long Pulse Radar Test Waveform
The parameters for this waveform are randomly chosen. Thirty unique waveforms are required for the
Long Pulse Radar Type waveforms. If more than 30 waveforms are used for the Long Pulse Radar Type
waveforms, then each additional waveform must also be unique and not repeated from the previous
waveforms.
Each waveform is defined as follows:
1) The transmission period for the Long Pulse Radar test signal is 12 seconds.
2) There are a total of 8 to 20 Bursts in the 12 second period, with the number of Bursts being randomly chosen.
This number is Burst Count.
3) Each Burst consists of 1 to 3 pulses, with the number of pulses being randomly chosen. Each Burst within the 12
second sequence may have a different number of pulses.
4) The pulse width is between 50 and 100 microseconds, with the pulse width being randomly chosen. Each pulse
within a Burst will have the same pulse width. Pulses in different Bursts may have different pulse widths.
5) Each pulse has a linear frequency modulated chirp between 5 and 20 MHz, with the chirp width being randomly
chosen. Each pulse within a transmission period will have the same chirp width. The chirp is centered on the pulse.
For example, with a radar frequency of 5300 MHz and a 20 MHz chirped signal, the chirp starts at 5290 MHz and
ends at 5310 MHz.
6) If more than one pulse is present in a Burst, the time between the pulses will be between 1000 and 2000
microseconds, with the time being randomly chosen. If three pulses are present in a Burst, the random time interval
between the first and second pulses is chosen independently of the random time interval between the second and
third pulses.
7) The 12 second transmission period is divided into even intervals. The number of intervals is equal to Burst
Count. Each interval is of length (12,000,000 / Burst Count) microseconds. Each interval contains one Burst. The
start time for the Burst, relative to the beginning of the interval, is between 1 and [(12,000,000 / Burst Count) –
(Total Burst Length) + (One Random PRI Interval)] microseconds, with the start time being randomly chosen. The
step interval for the start time is 1 microsecond. The start time for each Burst is chosen randomly.
A representative example of a Long Pulse Radar Type waveform:
1) The total test waveform length is 12 seconds.
2) Eight (8) Bursts are randomly generated for the Burst Count.
3) Burst 1 has 2 randomly generated pulses.
Report No.: FCC17010001A-8
Page 11 of 26
4) The pulse width (for both pulses) is randomly selected to be 75 microseconds.
5) The PRI is randomly selected to be at 1213 microseconds.
6) Bursts 2 through 8 are generated using steps 3 – 5.
7) Each Burst is contained in even intervals of 1,500,000 microseconds. The starting location for Pulse 1, Burst 1 is
randomly generated (1 to 1,500,000 minus the total Burst 1 length + 1 random
PRI interval) at the 325,001 microsecond step. Bursts 2 through 8 randomly fall in successive 1,500,000
microsecond intervals (i.e. Burst 2 falls in the 1,500,001 – 3,000,000 microsecond range).
Figure 1 provides a graphical representation of the Long Pulse Radar Test Waveform.

2.7 Frequency Hopping Radar Test Waveform
For the Frequency Hopping Radar Type, the same Burst parameters are used for each waveform. The hopping
sequence is different for each waveform and a 100-length segment is selected from the hopping sequence defined
by the following algorithm: 4
The first frequency in a hopping sequence is selected randomly from the group of 475 integer frequencies from
5250 – 5724 MHz. Next, the frequency that was just chosen is removed from the group and a frequency is
randomly selected from the remaining 474 frequencies in the group. This process continues until all 475
frequencies are chosen for the set. For selection of a random frequency, the frequencies remaining within the group
are always treated as equally likely.

5. TEST PROCEDURE
5.1 DFS MEASUREMENT SYSTEM
A complete DFS Measurement System consists of two subsystems:
(1) The Radar Signal Generating Subsystem and
(2) The Traffic Monitoring Subsystem.
The control PC is necessary for generating the Radar waveforms in Table 10, 11 and 12. The traffic
monitoring subsystem is specified to the type of unit under test (UUT).
The test transmission will always be from the Master Device to the Client Device. While the Client
device is set up to associate with the Master device and play the MPEG file (6 y Magic Hours) from
Master device, the designated MPEG test file and instructions are located at:
http://ntiacsd.ntia.doc.gov/dfs/.
5.2 CALIBRATION OF DFS DETECTION THRESHOLD LEVEL

time and channel move time.
