ISEDCRSS-247 issue 1 & 2 Major differences between old and new versions of the standard
RSS-247, Issue 2 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, with in which compliance with RSS-247, Issue 2, or Issue 1,will be accepted. After this period, only applications for certification of equipment under RSS-247, Issue 2, will be accepted.
Listed below arethe changes:
1.New section 3.3: state the requirement for emissions that fall within restricted frequency bands to comply with the provisions in RSS-Gen, General Requirements for Compliance of Radio Apparatus;
2.Section 5.4(b): reinstated the former e.i.r.p. limit for frequency hopping systems operating in the band2400-2483.5 MHz, which employ a hopset with less than 75 channels;
3.Section 6.2: add a clarification to ensure that emissions that fall within restricted frequency bands shall comply with the provisions in RSS-Gen;
4.Section 6.2: state the measurement method for power and unwanted emission limits for licence-exempt local area network devices and digital transmission systems operating in the 5 GHz band;
5.Section 6.2.1 and 6.2.2: add a provision to allow original equipment manufacturer (OEM) devices installed in road vehicles to operate in the band 5150-5250 MHz with an e.i.r.p. limit of 30 mW or 1.76 + 10 log10B, dBm, whichever is less stringent;B is the 99% emission bandwidth in megahertz.
6.Section 6.2.1.2: clarify the requirement for devices operating in the band 5150-5250 MHz, which have bandwidth that falls into the band 5250-5350 MHz;
7.Section 6.2.2.2 (b): permit the requisite "for indoor use only" notice for equipment operating in the band5250-5350 MHz to be included in the user manual;
8.Section 6.2.2.3: apply the requirement of e.i.r.p. at different elevations for equipment operating in the band5250-5350 MHz to outdoor fixed devices only;
9.Section 6.2.4.2: modify the unwanted emission limits for LE-LAN devices and DTS operating in the band5725-5850 MHz;
10.Annex A: delete the word "pre-installation" to clarify that the verification of e.i.r.p. compliance at different elevations for devices operating in the band 5250-5350 MHz needs to be done at the time of certification (before installation); the verification of compliance must be submitted with the test report for equipment requiring certification.
