Methods of Measurement of the Electromagnetic and Operational Compatibility of UPCS Devices
47CFR15, Subpart D—Unlicensed PCS Devices, as of December 29 2004 ANSI test
Maximum
spectrum
occupancy
15.323(c)(5).4
No device or group of co-operating devices located within 1 meter of each
other shall, during any frame period, occupy more than 6 MHz of
aggregate bandwidth, or alternatively, more than one third of the time and
spectrum windows defined by the system.
Declaration
Random waiting 15.323(c)(6)
If the selected combined time and spectrum windows are unavailable, the
device may either select and monitor different windows or seek to use the
same windows after waiting an amount of time, randomly chosen from a
uniform random distribution between 10 and 150 milliseconds,
commencing when the channel becomes available.
8.1.3
Monitoring
requirements
15.323(c)(7)
Monitoring
bandwidth
15.323(c)(7).1
The monitoring system bandwidth must be equal to or greater than the
emission bandwidth of the intended transmission.
7.4
Monitoring
reaction time
15.323(c)(7).2
The monitoring system shall have a maximum reaction time less than
50 × SQRT (2.5/emission bandwidth in MHz) µs for signals at the
applicable threshold level but shall not be required to be less than 50 µs.
If a signal is detected that is 6 dB or more above the applicable threshold
level, the maximum reaction time shall be 35 × SQRT (2.5/emission
bandwidth in MHz) µs but shall not be required to be less than 35 µs.
7.5
Monitoring
antenna
15.323(c)(8)
The monitoring system shall use the same antenna used for transmission,
or an antenna that yields equivalent reception at that location.
Clause 4
Monitoring
threshold
relaxation
15.323(c)(9)
Devices that have a power output lower than the maximum permitted
under the rules may increase their monitoring detection threshold by one
decibel for each one decibel that the transmitter power is below the
maximum permitted.
Clause 4
Duplex system
LBT
15.323(c)(10)
An initiating device may attempt to establish a duplex connection by
monitoring both its intended transmit and receive time and spectrum
windows. If both the intended transmit and receive time and spectrum
windows meet the access criteria, then the initiating device can initiate a
transmission in the intended transmit time and spectrum window. If the
power detected by the responding device can be decoded as a duplex
connection signal from the initiating device, then the responding device
may immediately begin transmitting on the receive time and spectrum
window monitored by the initiating device.
