COMMUNICATING DATA USING WIDEBAND COMMUNICATIONS
First Claim
1. A method for communicating data, the method comprising:
- detecting, using a first transmitter on a first channel, a state of communications by a second transmitter over a second channel; and
synchronizing transmissions by the first transmitter with transmissions by the second transmitter based on the detected state, wherein the first channel and the second channel are included in a transmission medium other than a copper telephone wire between and including a carrier facility and a termination of the copper telephone wire at an access point at a user premise and copper telephone wire in a cable riser in multi-tenant units and multi-dwelling buildings.

Abstract
This disclosure relates to varying load and modulation applied to each of multiple frequency subchannels based on anticipated attenuation experienced by those subchannels. Communicating data includes identifying a static component of a transmission medium for wideband communications having at least two subchannels determining a function of noise is attenuation versus frequency for the static component selecting wideband modulation schemes for the subchannels based on the function determined and communicating a data signal over the subchannels. The transmission medium includes a medium other than a copper telephone wire between and including a carrier facility and a termination of the copper telephone wire at an access point at a user premise and copper telephone wire in a cable riser in multitenant units and multi-dwelling buildings. Independent demodulation functions may be applied to at least two of the subchannels.

10. A method for communicating data, the method comprising:
-
identifying frequencies in a wideband communication channel that require reduced emissions, wherein the wideband communication channel is over a transmission medium that includes a medium other than a copper telephone wire between and including a carrier facility and a termination of the copper telephone wire at an access point at a user premise and copper telephone wire in a cable riser in multi-tenant units and multi-dwelling buildings; and applying a digital frequency-domain filter to a transmitted signal to reduce the emissions of the identified frequencies. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. A system for communicating data, comprising:
-
a first transmitter on a first channel; and a second transmitter on a second channel, wherein the first transmitter is structured and arranged to detect a state of communications by the second transmitter over the second channel and to synchronize transmissions by the first transmitter with transmissions by the second transmitter based on the state detected, wherein the first channel and the second channel are included in a transmission medium other than a copper telephone wire between and including a carrier facility and a termination of the copper telephone wire at an access point at a user premise and copper telephone wire in a cable riser in multi-tenant units and multi-dwelling buildings. - View Dependent Claims (19, 20)
