Radio Standards Specification RSS-139, Issue 3, Advanced Wireless Services (AWS) Equipment Operating in the Bands 1710-1780 MHz and 2110-2180 MHz, replaces RSS-139, Issue 2, Advanced Wireless Services Equipment Operating in the Bands 1710-1755 MHz and 2110-2155 MHz, dated February 2009.
This document will be in force as of its publication on Industry Canada’s website.
Listed below are the changes:
- the frequency bands have been extended from 1710-1755 MHz and 2110-2155 MHz to 1710-1780 MHz and 2110-2180 MHz;
- the requirement for receiver standard spurious emissions has been removed, as it is incorporated in RSS-Gen;
- requirements have been added for the new extended frequency bands;
- the electronic serial number (ESN) has been phased out since 2008 and the international mobile subscriber identity (IMSI) information is now stored on the Subscriber Identity Module (SIM) card, which is not part of the device (Consequently, both ESN and IMSI requirements have been removed.); and
- the provision for cordless-mode telephone base stations has been removed.

This Radio Standards Specification (RSS) sets out the requirements for the certification of transmitters used in radiocommunications systems to provide Advanced Wireless Services (AWS) in the bands 1710-1780 MHz and 2110-2180 MHz.
Equipment certified under this standard is classified as Category I equipment and a technical acceptance certificate (TAC), issued by the Certification and Engineering Bureau of Industry Canada, or a certificate issued by a certification body (CB), is required.
Equipment operating in the ancillary terrestrial component (ATC)Footnote 1 of the frequency bands 2000-2020 MHz and 2180-2200 MHz is certified under RSS-170, Mobile Earth Stations and Ancillary Terrestrial Component Equipment Operating in the Mobile-Satellite Service Bands.
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 in the Official Publications section on the following website: www.ic.gc.ca/spectrum.
The following Industry Canada document should be consulted:
RSS-139 shall be used in conjunction with RSS-Gen, General Requirements for Compliance of Radio Apparatus, for general specifications and information relevant to the equipment for which this standard applies.
The transmitter power shall be measured in terms of a root-mean-square (RMS) average value.
Equipment shall be tested for all channels bandwidths and the emission limits shall be measured with the carrier frequency set at both the highest settable frequency and lowest settable frequency permitted by the design of the equipment.
The 56-bit MEID developed in the Third Generation Partnership Project 2 (3GPP2) and the IMEI developed in the Third Generation Partnership Project (3GPP) will be accepted by Industry Canada as complying with the requirements of this section.
- Each mobile transmitter in service must have a unique MEID or IMEI.
- The MEID or IMEI component must be permanently attached to a main circuit board of the mobile transmitter and the integrity of the unit’s operating software must not be alterable. The MEID or IMEI must be protected from fraudulent contact and tampering. If the MEID or IMEI component does not contain other information, that component must not be removable and its electrical connections must not be accessible. If the MEID or IMEI component contains other information, the MEID or IMEI must be encoded, using one or more of the following techniques:
- multiplication or division by a polynomial;
- cyclic coding; or
- the spreading of MEID or IMEI bits over various non-sequential memory locations.
- The MEID or IMEI must be factory set and not alterable, transferable, removable or otherwise able to be manipulated. AWS mobile equipment must be designed such that any attempt to remove, tamper with, or change the MEID or IMEI chip, its logic system or firmware as originally programmed by the manufacturer will render the mobile transmitter inoperative.
The frequency plan is described in SRSP-513.
The devices may employ any type of modulation techniques. The type of modulation used must be reported.
Mobile, portable and fixed user equipment in the band 1755-1780 MHz may operate only when under the control of a base station. The applicant shall include a statement of declaration of compliance and a description of how this control requirement is met.
The frequency stability shall be sufficient to ensure that the occupied bandwidth stays within the operating frequency block when tested to the temperature and supply voltage variations specified in RSS-Gen.
The equivalent isotropically radiated power (e.i.r.p.) for mobile and portable transmitters shall not exceed one watt. The e.i.r.p. for fixed and base stations in the band 1710-1780 MHz shall not exceed one watt.
Consult SRSP-513 for e.i.r.p. limits on fixed and base stations operating in the band 2110-2180 MHz.
In addition, the peak to average power ratio (PAPR) of the equipment shall not exceed 13 dB for more than 0.1% of the time, using a signal that corresponds to the highest PAPR during periods of continuous transmission.
- In the first 1.0 MHz bands immediately outside and adjacent to the equipment’s smallest operating frequency block,Footnote 2 which can contain the equipment’s occupied bandwidth, the emission power per any 1% of the emission bandwidth shall be attenuated below the transmitter output power P (in dBW) by at least 43 + 10 log10 p (watts) dB.
- After the first 1.0 MHz outside the equipment’s smallest operating frequency block, which can contain the equipment’s occupied bandwidth, the emission power in any 1 MHz bandwidth shall be attenuated below the transmitter output power P (in dBW) by at least 43 + 10 log10 p (watts) dB.
Mobile and portable equipment shall employ a means for limiting power to the minimum necessary for successful communications.
Mobile and portable equipment that transmits in the band 1755-1780 MHz and receives in the band 2155-2180 MHz shall be certified only if it can be capable of operating on all frequencies in the frequency bands 1710-1780 MHz and 2110-2180 MHz.
