Abstract

Nodes on a network are synchronized with each other using a clock transfer system. The communications channels between the nodes are then measured and calibrated for optimal bandwidth. The optimized channels and synchronization enables a new form of signaling based on precise control of the frequency, amplitude, and phase of the waveform of the signal. Receiving nodes receive information in order to locate the signal at the appropriate frequency, phase and amplitude. Precision control of these parameters also servers as a unique signature of the transmitting node preventing security breaches as the signal's characteristic are unique to the transmitting node. The channel is continuously updated with a precision control system to insure that the nodes are not out of phase.

Claims

exact text as granted — not AI-modified
What is claimed is:  
     
         1 . A method for increasing bandwidth of signals between a transmitting node and a receiving node coupled over a communications channel comprising the steps of: 
 receiving time synchronization data;    synchronizing the transmitting and receiving node using the synchronization data received;    measuring the capacity of the communications channel between the nodes;    calibrating the communications channel including the steps of: 
 calculating an internal phase offset and an internal frequency offset for the communication channel using a first reference signal,  
 internally calibrating the channel using said internal phase offset and said internal frequency offset,  
 calculating an external phase offset and an external frequency offset for the communication channel using a first reference signal, and  
 externally calibrating the channel using said external phase offset and said external frequency offset,  
   equalizing channel and signal distortions;    coding the signal to the amplitude and frequency of the receiving node;    sampling clock signals of the nodes; and    delivering phase delay control to the nodes in response to the sampled clock signal of one of the nodes exceeding a phase interval.    
     
     
         2 . (New) A system for increasing bandwidth of signals between a transmitting node and a receiving node coupled over a communications channel comprising the steps of: 
 receiving means for receiving time synchronization data;    synchronizing means for synchronizing the transmitting and receiving node using the synchronization data received;    measuring means for measuring the capacity of the communications channel between the nodes;    calibrating means calibrating the communications channel including the steps of: 
 internal phase offset means for calculating an internal phase offset and an internal frequency offset for the communication channel using a first reference signal,  
 internal calibrating means for internally calibrating the channel using said internal phase offset and said internal frequency offset,  
 external phase offset means for calculating an external phase offset and an external frequency offset for the communication channel using a first reference signal, and  
 external calibrating means for externally calibrating the channel using said external phase offset and said external frequency offset,  
   equalizing means for equalizing channel and signal distortions;    coding means for coding the signal to the amplitude and frequency of the receiving node;    sampling means for sampling clock signals of the nodes; and    control means for delivering phase delay control to the nodes in response to the sampled clock signal of one of the nodes exceeding a phase interval.
