IC 於5/28公告RSS-247 Issue 1，此標準取代原RSS-210 Annex8/9，主要適用產品為FHSS/ DTS/ UNII，與RSS-210 Annex8/9主要差異如下:

(1)增加802.11ac 160MHz/80+80MHz說明

(2)新增DFS測試可以參考FCC KDB 905462或是EN 301 893，但是limit仍與FCCㄧ致‧

(3)5150-5250MHz仍限制為indoor used only‧

(4)5150-5250MHz如果26dB頻寬(原先為99% BW)的edge frequency佔用到5250-5350MHz頻段則必須符合DFS要求‧

(5)原5150-5250MHz以及5250-5350MHz其unwanted emission限制5150-5350MHz外需<-27dBm/MHz，新增要求當產品使用5250-5350MHz時 其unwanted emission需考量band edge也必須符合-27dBm/MHz，若未符合則此頻段亦必須被限制為indoor used‧

(6)如果產品有overlapping，如802.11ac 使用160MHz或80+80MHz時，5150-5250MHz/ 5250-5350MHz兩頻段會同時使用，這架構之下兩頻段都必須被限制為indoor used only‧

(7)新增ERFPA(external RF Power Amplifier)，如果ERFPA與RF transmitter是可分開銷售，transmitter測試認證時仍必需搭配ERFPA，市場上ERFPA手冊及包裝必須註明以下警語

Under Industry Canada regulations, this external radio frequency power amplifier (insert Industry

Canada certification number of radio frequency power amplifier) may only be used with the

transmitter with which the amplifier has been certified by Industry Canada. The certification number

for the transmitter with which this amplifier is permitted to operate is IC:XX…X-YY…Y.
