1. Scope

This Radio Standards Specification sets outstandards for transmitters and receivers for the narrowband personalcommunication service (PCS) in the bands 901-902 MHz, 930-931 MHz and 940-941 MHz.

2. General

Equipment certified under this standard isclassified as Category I equipment and requires a technical acceptancecertificate (TAC) issued by the Certification and Engineering Bureau ofInnovation, Science and Economic Development, or a certificate issued by acertification body (CB), pursuant to Section 4(2) of the RadiocommunicationAct.

2.1 Licensing Requirements

The radio equipment covered by thisstandard is subject to licensing pursuant to Subsection 4(1) of the Radiocommunication Act.

2.2 RSS-Gen Compliance

RSS-134 shall be used in conjunction withRSS-Gen, GeneralRequirements for Compliance of Radio Apparatus, for generalspecifications and information relevant to the equipment for which thisstandard applies.

2.3 Radio Frequency Exposure

The requirements in RSS-102, Radio Frequency(RF) Exposure Compliance of Radiocommunication Apparatus (All Frequency Bands),must be met.

2.4 Related Documents

All Spectrum Management and Telecommunications publications are available on Innovation, Science and Economic Development Canada’s website at http://www.ic.gc.ca/spectrum under Official Publications.

The following departmental document should be consulted:

SRSP-509, Technical Requirements for Narrowband Personal Communication Services in 901‑902 MHz, 930-931 MHz and 940-941 MHz (SRSP: Standard Radio SystemPlan)

3. Measurement Methods

3.1 Transmitter Output Power

The power to be measured shall be themaximum output power, averaged over any 100 ms interval, measured with aspectrum analyzer of resolution bandwidth wider than the occupied bandwidth ofthe transmitter. The video bandwidth shall be greater than or equal to threetimes the resolution bandwidth. Alternatively, the spectrum analyzer can be setto the peak hold mode.

3.2 Transmitter Unwanted Emissions

Unwanted emissions are to be measured when the transmitter is operating at the manufacturer’s rated power and modulated with signals representative of those encountered in a real system operation.

4. Transmitter Standard Specifications

4.1 Channel Spacings and Authorized Bandwidths

The standard channel spacings are 12.5 and 50 kHz. The authorized bandwidth is 10 kHz for 12.5 kHz spaced channels and 45 kHz bandwidth for 50 kHz spaced channels.

Channel aggregation using adjacent channels is also permitted provided that it is shown in the equipment certificationapplication that frequency spectrum efficiency is maintained by such aggregation. For aggregated channels, the authorized bandwidth is 5 kHz less than the total aggregated channel width.

For frequency channeling, plan and permissible antenna height information, refer to SRSP-509.

4.2 Types of Modulation

The devices may employ any type of modulation techniques. The type of modulation used must be reported.

4.3 Typical Output Power

  1. Stations transmitting in the 901-902 MHz band and all mobile stations in the 930-931 MHz and 940-941 MHz bands are limited to 7 watts effective radiated power (ERP) (11.5 watts effective isotropic radiated power (EIRP)).
  2. Base stations transmitting in the 930-931 MHz and 940-941 MHz bands can be certified to any manufacturer's rated power that respects the ERP restrictions of SRSP-509.
  3. For an aggregated channel, the permissible power of a single transmitter does not vary with its bandwidth.

4.4 Transmitter Unwanted Emissions

4.4.1 Minimum Standard for Spacings Exceeding 12.5 kHz(Bandwidth > 10 kHz)

The power of emissions from the transmitterwith modulated carrier shall be attenuated below the transmitter power (P) inaccordance with the following schedule (where the displacement frequency fdmeasured in kHz starts from the edge of the authorized bandwidth):

  1. For fd up to and including 40 kHz: at least 116 log10((fd+10)/6.1) dB, or 50+10log10 (P) dB, or 70 dB, whichever is less stringent, using a spectrum analyzer of 300 Hz resolution bandwidth;
  2. For fd of more than 40 kHz: at least 43+10 log10 (P) dB, or 80 dB, whichever is less stringent, using a spectrum analyzer of 30 kHz resolution bandwidth.

4.4.2 Minimum Standard for 12.5 kHz Spaced Equipment (Bandwidth = 10 kHz)

The power of emissions from the transmitterwith modulated carrier shall be attenuated below the transmitter power (P) inaccordance with the following schedule (where the displacement frequency fd,measured in kHz, starts from the edge of the authorized bandwidth):

  1. For fd up to and including 20 kHz: at least 116 log10((fd+5)/3.05) dB, or 50+10 log10 (P) dB, or 70 dB, whichever is less stringent, using a spectrum analyzer of 300 Hz resolution bandwidth;
  2. For fd of more than 20 kHz: at least 43+10 log10 (P) dB, or 80 dB, whichever is less stringent, using a spectrum analyzer of 30 kHz resolution bandwidth.

4.5 Frequency Stability

The RadioFrequency carrier frequency shall not depart from the reference frequency inexcess of ± 0.0001% (± 1 ppm). 

In lieu ofmeeting the above stability value, the test report may show that the frequencystability is sufficient to ensure that the emission bandwidth stays within theoperating frequency block when tested to the temperature and supply voltagevariations specified in RSS-Gen.
