Issue 3 of Radio Standards Specification RSS-199, Broadband Radio Service (BRS) Equipment Operating in the Band 2500‑2690 MHz, replaces issue 2, dated October 2014.
This document will be in force as of its publication on Innovation, Science and Economic Development Canada's (ISED) website. However, a transition period of six (6) months following its publication will be provided, within which compliance with RSS‑199, issue 3, or issue 2, will be accepted. After this period, only compliance with RSS‑199, issue 3, will be accepted.
Listed below are the changes:
- the transmitter power can be measured in terms of average instead of peak value
- a requirement has been added regarding transmitters' peak-to-average power ratio (PAPR)
- ANSI C63.26‑2015, American National Standard for Compliance Testing of Transmitters Used in Licensed Radio Services, is referenced for measuring the output power and e.i.r.p. of equipment with multiple antennas

This Radio Standards Specification (RSS) sets out certification requirements for BRS equipment in the frequency band 2500-2690 MHz.
2. General information
Equipment covered by this standard is classified as Category I equipment and requires a technical acceptance certificate (TAC) issued by the Certification and Engineering Bureau (CEB) of Innovation, Science and Economic Development Canada (ISED), or a certificate issued by a recognized certification body (CB).
2.1 Licensing requirements
Equipment covered by this standard is subject to licensing pursuant to subsection 4(1) of the Radiocommunication Act.
2.2 Related documents
All Spectrum Management and Telecommunications publications are available on the website under Official publications.
The following American National Standards Institute document should be consulted:
The following ISED document should be consulted:
Standard Radio System Plan SRSP-517, Technical Requirements for Broadband Radio Service (BRS) in the Band 2500-2690 MHz
The terms below are defined for the purposes of this standard.
Base station equipment is equipment that provides connectivity to, as well as management and control of, the subscriber equipment.
Subscriber equipment is equipment that provides connectivity between the user's equipment and base station equipment.
Fixed subscriber equipment is subscriber equipment that is used at a fixed point and is not operational while in motion. Nomadic subscriber equipment is not considered to be fixed subscriber equipment.
Mobile subscriber equipment is subscriber equipment that is intended to be used while in motion and during halts at unspecified points. Handheld, portable and nomadic subscriber equipment is considered to be mobile subscriber equipment.
3. General requirements
This issue of RSS-199 shall be used in conjunction with RSS-Gen, General Requirements for Compliance of Radio Apparatus, for general specifications and information relevant to the equipment to which this standard applies.
4. Transmitter and receiver standard specifications
4.1 Types of modulation
Equipment certified under this standard shall employ digital modulation.
4.2 Channel bandwidth
The channel bandwidth shall be equal to or greater than 1 MHz and shall be reported by the certification applicant.
4.3 Transmitter frequency stability
The transmitter frequency stability limit shall be determined as follows:
- the frequency offset shall be measured according to the procedure described in RSS-Gen and recorded
- using a resolution bandwidth equal to that permitted within the 1 MHz band immediately outside the channel edge, as found in section 4.5, reference points will be selected at the unwanted emission limits, which comply with the attenuation specified in section 4.5 for the type of device under test, on the emission mask of the lowest and highest channels. The frequency at these points shall be recorded as fL and fH respectively
The applicant shall ensure compliance with frequency stability requirements by showing that fL minus the frequency offset and fH plus the frequency offset is within the frequency range in which the equipment is designed to operate.
4.4 Transmitter output power and equivalent isotropically radiated power (e.i.r.p.)
The transmitter output power shall be measured in terms of average value.
For base station equipment, refer to SRSP-517 for the maximum permissible e.i.r.p.
For mobile subscriber equipment, the e.i.r.p. shall not exceed 2 W. For fixed subscriber equipment, the transmitter output power shall not exceed 2 W and the e.i.r.p. shall be limited to 40 W.
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.
For equipment with multiple antennas, the transmitter output power and e.i.r.p shall be measured according to ANSI C63.26‑2015.
4.5 Transmitter unwanted emissions
In the 1 MHz band immediately outside and adjacent to the channel edge, the unwanted emission power shall be measured with a resolution bandwidth of at least 1% of the occupied bandwidth for base station and fixed subscriber equipment, and 2% for mobile subscriber equipment. Beyond the 1 MHz band, a resolution bandwidth of 1 MHz shall be used. A narrower resolution bandwidth can be used, provided that the measured power is integrated over the full required measurement bandwidth of 1 MHz, or 1% or 2% of the occupied bandwidth, as applicable.
Equipment shall comply with the following unwanted emission limits:
- for base station and fixed subscriber equipment, the power of any unwanted emissions measured as above shall be attenuated (in dB) below the transmitter power, P (dBW), by at least 43 + 10 log10 p
- for mobile subscriber equipment, the power of any unwanted emissions measured as above shall be attenuated (in dB) below the transmitter power, P (dBW), by at least:
- 40 + 10 log10 p from the channel edges to 5 MHz away
- 43 + 10 log10 p between 5 MHz and X MHz from the channel edges, and
- 55 + 10 log10 p at X MHz and beyond from the channel edges
In addition, the attenuation shall not be less than 43 + 10 log10 p on all frequencies between 2490.5 MHz and 2496 MHz, and 55 + 10 log10 p at or below 2490.5 MHz.
In (a) and (b), p is the transmitter power measured in watts and X is 6 MHz or the equipment occupied bandwidth, whichever is greater.
