Simultaneous use of multiple radio frequency channels
First Claim
1. A computer-implemented method for providing simultaneous use of multiple radio frequency channels, the method comprising:
- identifying data that is designated for wireless transmission to a remote computing device;
generating a digital signal that encodes the data for transmission across a band of radio frequency channels;
determining multiple radio frequency channels in the band that are available;
filtering the digital signal to substantially reduce a power level of the digital signal at frequencies that correspond to channels in the band that have not been determined to be available;
converting the filtered digital signal to an analog signal; and
providing the analog signal to an analog transmitter that isolates the band of radio frequency channels to generate an isolated analog signal and that wirelessly transmits the isolated analog signal over the multiple available channels using one or more antennas.

Abstract
In general, the subject matter described in this specification can be embodied in methods, systems, and program products for identifying data that is designated for wireless transmission to a remote computing device. A digital signal that encodes the data for transmission across a band of radio frequency channels is generated. Multiple radio frequency channels in the band that are available are determined. The digital signal is filtered to substantially reduce a power level of the digital signal at frequencies that correspond to channels in the band that have not been determined to be available. The filtered digital signal is converted to an analog signal. The analog signal is provided to an analog transmitter that isolates the band of channels to generate an isolated analog signal and that wirelessly transmits the isolated analog signal over the multiple available channels using one or more antennas.

15. A computer-implemented method for providing simultaneous use of multiple radio frequency channels, the method comprising:
-
receiving with an antenna a radio frequency signal; filtering the signal by isolating a band of multiple radio frequency channels to generate an isolated band of radio frequency channels; digitizing the isolated signal to form a digital signal, wherein the digital signal includes data that identifies characteristics of each channel in the band; presenting the digital signal to a digital signal processing device, so that the digital signal processing device can process any or all channels of the band; determining multiple radio frequency channels in the band that are available; processing the digital signal by filtering the digital signal to substantially reduce a power level of the digital signal at frequencies that correspond to channels in the band that have not been determined to be available; and processing the filtered digital signal to identify a stream of data that was encoded across the radio frequency channels that are available. - View Dependent Claims (16)
