Method and system of combining signals in bpl communications

Abstract

A system for communicating BPL signals is provided, including a BPL modem having a first internal modem and a second internal modem, the first internal modem and the second internal modem each in communication with a RF combiner; the RF combiner in communication with a medium voltage power line; and wherein the RF combiner combines signals from the first internal modem and the second internal modem into a single signal, and communicates the single signal to the medium voltage power line.

1 . A method of communicating signals from a BPL modem to a medium voltage power line, comprising:
 a) communicating a first signal for a medium voltage power line from a first signal source;   b) communicating a second signal for the medium voltage power line from a second signal source;   c) combining said first and second signals into a third signal prior to said signals reaching the medium voltage power line; and   d) communicating said third signal to said medium voltage power line.   
     
     
         2 . The method of  claim 1  wherein said first signal source is a first internal modem within a BPL modem. 
     
     
         3 . The method of  claim 2  wherein said second signal source is a second internal modem within said BPL modem. 
     
     
         4 . The method of  claim 3  wherein said first and second signals are combined by a RF combiner. 
     
     
         5 . The method of  claim 4  wherein said first signal passes through a first RF filter prior to reaching said RF combiner. 
     
     
         6 . The method of  claim 5  wherein said second signal passes through a second RF filter prior to reaching said RF combiner. 
     
     
         7 . The method of  claim 6  wherein, after passing through said first RF filter, said first signal has a first allotted bandwidth. 
     
     
         8 . The method of  claim 7  wherein, after passing through said second RF filter, said second signal has a second allotted bandwidth, said first allotted bandwidth not overlapping with said second allotted bandwidth. 
     
     
         9 . A system for communicating BPL signals, comprising:
 a) a BPL modem having a first internal modem and a second internal modem, said first internal modem and said second internal modem each in communication with a RF combiner;   b) said RF combiner in communication with a medium voltage power line; wherein said RF combiner combines signals from said first internal modem and said second internal modem into a third signal, and communicates said third signal to said medium voltage power line.   
     
     
         10 . The system of  claim 9  wherein said first internal modem communicates upstream signals. 
     
     
         11 . The system of  claim 10  wherein said second internal modem communicates downstream signals. 
     
     
         12 . The system of  claim 11  further comprising a first RF filter in communication with said first internal modem and said RF combiner. 
     
     
         13 . The system of  claim 12  further comprising a second RF filter in communication with said second internal modem and said RF combiner. 
     
     
         14 . The system of  claim 13  wherein, said first signal has a first allotted bandwidth, wherein said first RF filter filters a first signal from said first internal modem to said first allotted bandwidth. 
     
     
         15 . The system of  claim 14  wherein, said second signal has a second allotted bandwidth, said first allotted bandwidth not overlapping with said second allotted bandwidth, wherein said second RF filter filters a second signal from said second internal modem to said second allotted bandwidth.
