the Minister of Industry
Engineering, Planning and Standards Branch
This Radio Standard Specification (RSS) sets out certification requirements for MBS radio transmitters and receivers in the frequency bands 698-756 MHz and 777-787 MHz.
Equipment covered by this standard is classified as Category I equipment. Either a technical acceptance certificate (TAC) issued by the Certification and Engineering Bureau of Industry Canada or a certificate issued by a recognized Certification Body (CB) is required.
Equipment covered by this standard is subject to licensing pursuant to subsection 4(1) of the Radiocommunication Act.
All Spectrum Management and Telecommunications publications are available under the Official Publications link on the following website: www.ic.gc.ca/spectrum.
The following document should be consulted:
SRSP — Standard Radio System Plan
- Mobile Equipment
- is equipment that is designed for use while in motion as well as during halts at unspecified points in which the radiating antenna is at least 20 cm apart from the human body.
- Portable Equipment
- is equipment with an embedded radiating antenna having direct contact with or within 20 cm of the human body.
- Fixed subscriber equipment
- is fixed equipment that provides connectivity between the user’s equipment and base station equipment. Fixed subscriber equipment is used at a fixed point and is not operational while in motion.
RSS-130 shall be used in conjunction with RSS-Gen, General Requirements and Information for the Certification of Radiocommunication Apparatus, for general specifications and information relevant to the equipment for which this standard applies.
Equipment certified under this standard shall employ digital modulation.
The frequency bands 698-756 MHz and 777-787 MHz are divided into small frequency blocks as per SRSP- 518. Equipment shall operate according to the frequency plan given in the SRSP.
The transmitter frequency stability limit shall be determined as follows:
- (a) The frequency offset shall be measured according to the procedure described in RSS-Gen and recorded;
- (b) Using a resolution bandwidth of 1% of the occupied bandwidth, a reference point at the unwanted emission level which complies with the attenuation of 43 + 10 log10 p (watts) on the emission mask of the lowest and highest channel shall be selected, and the frequency at these points shall be recorded as fL and fH respectively.
The applicant shall ensure frequency stability by showing that fL minus the frequency offset and fH plus the frequency offset shall be within the frequency range in which the equipment is designed to operate.
The transmitter output power shall be measured in terms of average power.
For base and fixed equipment, refer to SRSP-518 for power limits.
The e.i.r.p. shall not exceed 50 watts for mobile equipment or for outdoor fixed subscriber equipment, nor shall it exceed 5 watts for portable equipment or for indoor fixed subscriber equipment.
In addition, the peak-to-average power ratio (PAPR) of the transmitter shall not exceed 13 dB for more than 0.1% of the time and shall use a signal corresponding to the highest PAPR during periods of continuous transmission.
4.5.1 Correlated Transmission
When multiple antennas are used to:
- (a) transmit the same digital data in a given symbol period (even with different coding or phase shifts) for transmission diversity; or
- (b) steer signal energy towards a particular direction for enhanced directional gain (i.e. beamforming); or
- (c) devise any other transmission mode,
and where signals from different antennas are correlated, the e.i.r.p. shall be calculated based on the aggregate power (conducted across all antennas) and resulting directional gain dBi, Gmax + 10 log10 N, where N is the number of antennas and Gmax is the highest gain in dBi among all antennas.
4.5.2 Uncorrelated transmission
When multiple transmitted antennas are used and each antenna:
- (a) transmits different digital data during any given symbol period (i.e. Space-Time Block Codes or Space-Time Codes); or
- (b) transmits independent parallel data stream over the same frequency bandwidth in order to increase data rates (i.e. spatial multiplexing); or
- (c) forms any other transmission mode,
and where signals from different antennas are completely uncorrelated, the e.i.r.p. shall be calculated based on the aggregate power (conducted across all antennas) and maximum antenna gain Gmax.
4.6.1 The power of any unwanted emissions in any 100 kHz bandwidth on any frequency outside the frequency range(s) within which the equipment is designed to operate shall be attenuated below the transmitter power, P (dBW), by at least 43 + 10 log10 p (watts), dB. However, in the 100 kHz band immediately outside the equipment’s operating frequency range, a resolution bandwidth of 30 kHz may be employed.
4.6.2 In addition to the limit outlined in Section 4.6.1 above, equipment operating in the frequency bands 746-756 MHz and 777-787 MHz shall also comply with the following restrictions:
- (a) The power of any unwanted emissions in any 6.25 kHz bandwidth for all frequencies between 763-775 MHz and 793-806
MHz shall be attenuated below the transmitter power, P (dBW), by at least:
- (i) 76 + 10 log10 p (watts), dB, for base and fixed equipment, and
- (ii) 65 + 10 log10 p (watts), dB, for mobile and portable equipment.
- (b) The e.i.r.p. in the band 1559-1610 MHz shall not exceed −70 dBW/MHz for wideband signal and −80 dBW for discrete emission with bandwidth less than 700 Hz.
