Abstract
In various embodiment, the disclosed systems, methods, and apparatuses describe extending the usage spectrum for cable networks (e.g., hybrid fiber-coaxial networks). In particular, embodiments of the disclosure described determining a first portion of a signal having a first frequency band, the first frequency band being greater than approximately 1.2 GHz; determining a second portion of the signal having a second frequency band, the second frequency band being less than or equal to approximately 1.2 GHz; applying an attenuation to the first portion of the signal; and transmitting the second portion of the signal at a flat power-spectral density. Various other related systems, methods, and apparatuses are described.
Claims20
A device, comprising:
- at least one memory that stores computer-executable instructions;
- and
- at least one processor configured to access the at least one memory, wherein the at least one processor is configured to execute the computer-executable instructions to:
- determine a first portion of a signal having a first frequency band, the first frequency band being greater than approximately 1.2 GHz;
- determine a second portion of the signal having a second frequency band, the second frequency band being less than or equal to approximately 1.2 GHz and greater than or equal to approximately 1 GHz;
- determine a third portion of the signal having a third frequency band, the third frequency band being less than or equal to approximately 1 GHz;
- cause to apply a first tilt to the second portion of the signal;
- cause to apply a second tilt to the third portion of the signal, wherein the second tilt is greater than the first tilt;
- and
- cause to transmit the first portion of the signal and the second portion of the signal.
A system, comprising:
- at least one memory that stores first computer-executable instructions;
- and
- at least one processor configured to access the at least one memory, wherein the at least one processor is configured to execute the first computer-executable instructions to:
- determine a first portion of a signal having a first frequency band;
- determine a second portion of the signal having a second frequency band, wherein the second frequency band is lower in a frequency spectrum than the first frequency band;
- determine a third portion of the signal having a third frequency band, wherein the third frequency band is lower in the frequency spectrum than the second first frequency band;
- cause to apply a first tilt to the second portion of the signal;
- cause to apply a second tilt to the third portion of the signal, wherein the second tilt is greater than the first tilt;
- and
- cause to transmit the first portion of the signal and the second portion of the signal.
A method, comprising:
- determining a first portion of a signal having a first frequency band;
- determining a second portion of the signal having a second frequency band, wherein the second frequency band is lower in a frequency spectrum than the first frequency band;
- determining a third portion of the signal having a third frequency band, wherein the third frequency band is lower in the frequency spectrum than the second first frequency band;
- causing to apply a first tilt to the second portion of the signal;
- causing to apply a second tilt to the third portion of the signal, wherein the second tilt is greater than the first tilt;
- and
- causing to transmit the first portion of the signal and the second portion of the signal.
