主要變化

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;

章節(jié)5.4（b）設(shè)備使用信道小于75個(gè)的 e.i.r.p.限值為4W，舊標(biāo)準(zhǔn)要求是0.5W。

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;

6.2章節(jié)要求禁用頻段內(nèi)的輻射應(yīng)滿足RSS-Gen中要求。

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;

6.2章節(jié)規(guī)定了工作在5GHz頻段設(shè)備的檢測方法，頻段的帶寬要求推薦應(yīng)以99%OBW為主。

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.

章節(jié)6.2 允許OEM使用頻段band 5150-5250 MHz和 5250-5350 MHz開發(fā)車載產(chǎn)品，產(chǎn)品須符合e.i.r.p限值30 mW 或 1.76 + 10log10B, dBm,限值取兩者最嚴(yán)格值；B 值為99%的輻射占用帶寬，單位為MHz。

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;

章節(jié)6.2.1.2 進(jìn)一步澄清工作頻段在5150-5250 MHz設(shè)備無用輻射要求，5150-5350 MHz帶外輻射限值為-27 dBm/MHz e.i.r.p.如果5250-5350 MHz內(nèi)的無用輻射低于信道功率26dB占用的帶寬落在此頻段內(nèi)，可認(rèn)為其輻射為其有意輻射，并須滿足5250-5350 MHz內(nèi)設(shè)備的所有要求，包括DFS,TPC等要求。

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;

工作在5250-5350 MHz內(nèi)的設(shè)備，章節(jié)6.2.2.2（b）最后一句話”shall belabelled or include in the user manual the following text “for indoor use only.”,要求警示語“for indoor use only.”放到說明書中或設(shè)備標(biāo)簽上，老標(biāo)準(zhǔn)只要求張貼在設(shè)備標(biāo)簽上。

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;

工作在5250-5350 MHz內(nèi)的設(shè)備，新增額外要求在章節(jié)6.2.2.3中，針對(duì)戶外產(chǎn)品最大e.i.r.p.超過200mW的情況，增加在不同角度的測量要求；非戶外產(chǎn)品最大e.i.r.p.超過200mW，須滿足6.6.6.3 b i) 或 ii) 。

9.Section 6.2.4.2: modify the unwanted emission limits for LE-LAN devices and DTS operating in the band5725-5850 MHz;

更詳細(xì)的規(guī)定了6.2.4.2章節(jié)的無用輻射要求。

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.

附錄A中去掉"pre-installation"。
