Claim of US Patent No. 10,194,437

1. A device, comprising:a first antenna;
an inductive power supply;
a memory to store instructions; and
a processor, communicatively coupled to the memory, to facilitate execution of the instructions to perform operations, the operations comprising:
receiving a plurality of modulated signals each operating in a respective one of a plurality of cellular bands, and each conforming to one of a plurality of signaling protocols, wherein the plurality of modulated signals is received via a first guided electromagnetic wave that conveys the modulated signals and that propagates along a transmission medium, wherein the transmission medium has an outer surface, wherein the inductive power supply is configured to receive power inductively from the transmission medium along which the first guided electromagnetic wave propagates, and wherein the inductive power supply is configured to power at least a portion of the device;
converting the plurality of modulated signals each operating in the respective one of the plurality of cellular bands to a plurality of frequency converted signals each operating in a respective one of a plurality of frequency bands, each frequency converted signal of the plurality of frequency converted signals comprising a corresponding modulated signal of the plurality of modulated signals frequency-shifted from a corresponding cellular band of the plurality of cellular bands to a corresponding frequency band of the plurality of frequency bands, the plurality of frequency bands differing from the plurality of cellular bands, and the converting being performed without modifying the plurality of signaling protocols; and
transmitting, by the first antenna, the plurality of frequency converted signals each operating in the respective one of the plurality of frequency bands for receipt by a recipient antenna of a recipient system of a plurality of systems, each of the plurality of systems including an antenna to form a distributed antenna system, the recipient antenna providing the plurality of frequency converted signals to the recipient system to facilitate conversion of at least one of the plurality of frequency converted signals to at least one modulated signal of the plurality of modulated signals operating in at least one cellular band of the plurality of cellular bands for wireless delivery to a wireless communication device.
