This Radio Standards Specification (RSS) sets out requirements for the certification of transmitters and receivers used in radiocommunications systems to provide Advanced Wireless Services (AWS) in the bands 1710-1755 MHz and 2110-2155 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 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 on Industry Canada's website at http://www.ic.gc.ca/spectrum under Official Publications. In addition to related documents specified in RSS-Gen, General Requirements and Information for the Certification of Radiocommunication Equipment, the following Industry Canada documents should be consulted:
CS – Compliance Specification
DC – Terminal Attachment Program Procedures
RSS – Radio Standards Specification
SRSP – Standard Radio System Plan
Emission bandwidth is, for the purpose of this document, defined as the width of the signal between two points, one below the carrier frequency and one above the carrier frequency, outside of which all emissions are attenuated at least 20 dB below the transmitter power (i.e. -20 dBc), when measured with a resolution bandwidth of approximately 1% of the occupied bandwidth. In lieu of the -20 dBc bandwidth, the occupied bandwidth may be used.
RSS-139 shall be used in conjunction with RSS-Gen for general specifications and information relevant to the equipment for which this standard applies.
The transmitter power can be measured in peak or average value. If the transmitter power to be measured is in peak value, the transmitter power shall be measured over any interval of continuous transmission using an instrument calibrated in terms of a root-mean-square-equivalent voltage. The measurement results shall be properly adjusted for any instrument limitation, such as detector response times, sensitivity, limited resolution bandwidth capability when compared to the emission bandwidth, etc., so as to obtain the maximum transmit output power of the emission over the channel bandwidth.
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.
5.1 Electronic Serial Number (ESN), Mobile Equipment Identifier (MEID), International Mobile Subscriber Identity (IMSI), or International Mobile Equipment Identity (IMEI)
The ESN is a 32-bit number that uniquely identifies an AWS mobile station to any AWS system. (Note: Other ESN schemes may be considered by Industry Canada. However, it is the system designer's responsibility to ensure a secure ESN.) The 56-bit MEID developed in 3GPP2 (3rd Generation Partnership Project 2) and the IMSI and IMEI developed in 3GPP (3rd Generation Partnership Project) will be accepted by Industry Canada as complying with the requirements of this section.
- Each mobile transmitter in service must have a unique ESN, MEID, IMSI or IMEI.
- The ESN, MEID, IMSI 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 ESN, MEID, IMSI or IMEI must be isolated from fraudulent contact and tampering. If the ESN, MEID, IMSI or IMEI component does not contain other information, that component must not be
removable and its electrical connections must not be accessible. If the ESN, MEID, IMSI or IMEI component contains other information, the ESN, MEID, IMSI or IMEI must be encoded using one
or more of the following techniques:
- multiplication or division by a polynomial;
- cyclic coding;
- the spreading of ESN, MEID, IMSI or IMEI bits over various non-sequential memory locations.
- The ESN, MEID, IMSI 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 ESN, MEID, IMSI or IMEI chip, its logic system or firmware as originally programmed by the manufacturer will render the mobile transmitter inoperative.
CTBS are permitted and are intended to form a cordless telephone system in conjunction with an AWS handset or handsets. The communication between the handsets and the CTBS will use the AWS provider's frequency band. Such a cordless system is intended for short-range and/or in-building usage. When the CTBS is certified (using this RSS), operation will be permitted under the AWS provider's licence.
The CTBS shall comply with this RSS and be certified under Radio Equipment Certification Procedure RSP-100. In cases where the CTBS is connected to a public telephone network, the CBTS shall also comply with Compliance Specification CS-03 and be registered according to Terminal Attachment Program Procedures DC-01.
The CTBS and the handset shall incorporate a security code of a minimum of 8 bits or equivalent to prevent unintentional line seizure, dialling or ringing. Although a description of the implementation of the code is required, the implementation need not be tested. For further details, refer to the section on "Cordless Telephones (General Conditions)" in RSS-210.
The radio frequency (RF) output power shall not exceed a level that is required for reliable communication.
An authorization protocol shall be put in place to allow the operation of the CTBS, based on the following principles:
- The CTBS must be controlled by the network of the AWS provider in order to receive permission to operate. Such a control mechanism may be provided by wireline or wireless facilities. The operation of a CTBS must be only on frequencies within the frequency sub-band assigned for use to the AWS provider and must operate only within the radio service coverage of the network that controls the CTBS.
- Upon receiving permission from the network to operate, and under no other circumstances, a CTBS will enable its transmitter to communicate with any associated certified handset and provide service using the frequency spectrum and operating parameters specified and/or permitted by the AWS provider.
- Until authorized for service by the network, neither the CTBS nor the handset shall be able to transmit in the cordless mode.
The applicant for certification shall provide a letter from one of the appropriate AWS providers stating that the CTBS authorization protocol has been tested and found to work satisfactorily.
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.
The frequency stability shall be sufficient to ensure that the emission bandwidth stays within the operating frequency block when tested to the temperature and supply voltage variations specified in RSS-Gen.
The average equivalent isotropically radiated power (e.i.r.p.) for fixed, mobile and portable transmitters in the 1710-1755 MHz shall not exceed 1 watt.
Consult SRSP-513 for e.i.r.p. limits on fixed and base stations operating in the 2110-2155 MHz band.
In addition, when the transmitter power is measured in terms of average value, the peak-to-average ratio of the power shall not exceed 13 dB.
- In the first 1.0 MHz bands immediately outside and adjacent to the equipment's operating frequency block, the emission power per any 1% of the emission bandwidth shall be attenuated below the transmitter output power P (in watts) by at least 43 + 10 log10(P), dB.
- After the first 1.0 MHz outside the equipment's operating frequency block, the emission power in any 1 MHz bandwidth shall be attenuated below the transmitter output power P (in watts) by at least 43 + 10 log10(P), dB.
Receiver spurious emissions shall comply with the limits specified in RSS-Gen.
