On April 1, 2018, the Minister of Innovation, Science and Economic Development of Canada (ISED) issued the Radio Standards Specification RSS-140 regarding the certification requirements for equipment operating in the public safety broadband frequency bands 758-768 MHz and 788-798 MHz. Equipment covered by this standard is classified as Category I equipment. Either a technical acceptance certificate (TAC) issued by ISED’s Certification and Engineering Bureau or a certificate issued by a certification body (CB) is required.
Regarding measurement methods, RSS-140 stands out the following aspects:
● Equipment shall employ digital modulation techniques.
● The frequency stability shall be sufficient to ensure that the occupied bandwidth stays within the operating frequency block when tested.
● The equivalent radiated power (e.r.p.) for control and mobile equipment shall not exceed 30 W. The e.r.p. for portable equipment shall not exceed 3 W.
● The power of any unwanted emission outside the bands 758-768 MHz and 788-798 MHz shall be attenuated as follows:
-For any frequency between 769-775 MHz and 799-806 MHz: 76 + 10 log (p), dB in a 6.25 kHz band for fixed and base station equipment. 65 + 10 log (p), dB in a 6.25 kHz band for mobile and portable/hand
-For any frequency between 775-788 MHz, above 806 MHz, and below 758 MHz: 43 + 10 log (p), dB in a bandwidth of 100 kHz or greater. However, in the 100 kHz bands immediately outside and adjacent to the frequency bands 758-768 MHz and 788-798 MHz, a resolution bandwidth of 30 kHz may be employed.
This document will come into force as of its publication on ISED website.
