SP 47 GHz — Spectrum Utilization Policy for Licence Exempt Wireless Devices in the Bands 46.7–46.9 GHz, 57–64 GHz and 76–77 GHz

Annex

Technical and System Requirements for Equipment Certification1
Parameter 46.7-46.9 GHz 59-64 GHz 76-77 GHz

* Note:
Unless otherwise specified (e.g. in 59-64 GHz), when the radiated emission limits are expressed in terms of the average value of the emission, and pulsed operation is employed, the measurement field strength shall be determined by averaging over one complete pulse train, including blanking intervals, as long as the pulse train does not exceed 0.1 seconds. As an alternative (provided the transmitter operates for longer than 0.1 seconds) or in cases where the pulse train exceeds 0.1 seconds, the measured field strength shall be determined from the average absolute voltage during a 0.1 second interval during which the field strength is at its maximum value. The exact method of calculating the average field strength shall be submitted with any application for certification or shall be retained in the measurement data file for equipment subject to notification or verification.

Power
No Limit - 500 mW

- Transmitters with emission bandwidth of less than 100 MHz must limit peak transmit output power to the product of 500 mW times their emission bandwidth, divided by 100 MHz.

- With necessary authorization, transmitters may be mounted in a group installation for simultaneous operation with one or more authorized transmitters. However, transmitters must not be equipped with external phase-locking inputs that permit beam-forming arrays to be realized.
No Limit
Measurement Requirements Above 30 GHz

Emissions from transmitters operating above 30 GHz
be measured to the fifth harmonic of the highest operating frequency or to 200 GHz (whichever is lower).

For field disturbance sensors operating in the 76-77 GHz band, spectrum will be investigated up to 231 GHz.
MHz resolution bandwidth for measurement instrument used to measure emissions above 1000 MHz
The measurement of conducted emissions above 40 GHz could accurately portray the radiated RF fields, provided that the antenna characteristics can be determined accurately. Accordingly, conducted measurements that are to be employed in order to facilitate measurements will be permitted.

Not
Applicable

Peak Power Density is to be measured with an RF detector that has detection bandwidth encompassing 59-64 GHz and video bandwidth of a minimum 10 MHz. (Or equivalent measurement method).

Not
Applicable

Frequency
Stability
Requirements
Fundamental emissions of millimetre wave devices must be contained within the specified frequency bands during all conditions of operations. For certification purposes, the equipment will be presumed to operate over the temperature range of -20 to +50 degrees Celsius with an input voltage variation of 85% to 115% of the rated input voltage. Should the equipment operate at temperatures lower than the tested range, it is expected that this requirement is still met.
