You are responsible for complying with any and all FCC rules regarding intentional transmitters. The USRP is not FCC type-accepted and does not come with any pre-authorized licenses on any frequency bands. One recommendation is to obtain an amateur radio license, which would allow transmission with the RFX900 in the 902-928 MHz band in the US within the rules and requirements of the amateur radio service. This does not address the cellular bands you were asking about. Many people, of course, ignore the above and assume that at a few milliwatts transmit power in an indoor environment, nobody will notice or care.
