Yes they are CFR 47. Part 22H has a limit of 7W ERP for mobile phones, but no manufacturer would ever do that high simply because the device would never pass SAR requirements. Part 24E is limited to 2W EIRP. Part 27 varies depending on the frequency of operation. For example, the eirp for the 2300MHz band is 50mW/MHz; portable stations in the 746-757 MHz, 776-788 MHz are allowed 3W eirp; eirp in the 1915-1920 MH band is 300mW; Mobile stations transmitting in the 1390-1392 MHz and 1432-1435 MHz bands are limited to 4 watts EIRP peak power. Mobile stations transmitting in the1392-1395 MHz band are limited to 1 watt EIRP peak power; BRS and EBS Mobile stations are limited to 2.0 watts EIRP; and in the 1700MHz band 1 W eirp. Part 90, except where the band overlaps part 22 bands, it is a maximum antenna conducted power limit of 100W in the 800MHz bands. But then again, regardless of the allowed power, SAR is still a limiting requirement. Thanks
