1. FCC site you would need to have your TCB request that the FCC put the application into Audit Mode so that the current manual exhibit could be superseded by the new final manual FCC RF Exposure Rules for Battery Operated Portable Devices QUESTION We manufacture battery operated personal wireless routers What is the FCC s position with respect to RF exposure compliance for these devices ANSWER There are currently many different battery operated personal wireless routers that are approved for use with mobile RF exposure conditions However most advertisements indicate that these devices can be used in one s pocket under the FCC s portable RF exposure category Though these devices are typically small in size they do not qualify for the FCC s mobile RF exposure conditions though they are advertised as such and are used by users as portable devices If a Grantee s device was approved under the mobile RF exposure category he may have to justify how mobile RF exposure conditions and limits apply to these devices Available external ports and external antennas for these devices create RF exposure issues To make matters worse many of these devices are now capable of being connected to laptop computers through USB ports or similar connections Simultaneous transmitting is also an issue as a portable wireless router requires multiple transmitters to operate simultaneously when a 3G cell phone and a portable Wi Fi transmitter are connected toget
