Abstract

The present invention concerns analog signal repeater system solutions of the general kind. It concerns in particular stability with analog signal repeater systems.

Claims

1. Analog signal repeater system used in a power grid and distribution system where repeaters with signal gains are applied to extend radio frequency transmission range across a number of termination cable junction arrangements in different physical positions with cables interconnecting them for stable utilization of repeater gains and for bandwidth improvement as a function of transmission range, comprising:

the signal repeater system with repeaters connected through differential signal couplers consisting of at least one signal coupler arrangement and at least two series impedances and at least one shunt impedance;

whereby at least one signal transmission range is facilitated to accept radio frequency gains at the junctions, wherein at least two of the electrically accessible junctions include at least one repeater at each of said junctions, where signal couplers on cables of the junctions facilitate signal bypassing of the junctions and where the combination of transfer losses and inserted dampening in each of the junctions between signal couplers at each of the junctions increase signal isolation between ports of the repeaters at the junctions to mitigate problems from undesired signal coupling between ports of the repeaters.

2. Analog signal repeater system according to claim 1, further comprising the system to be using one of said repeaters for each transmission direction at each of said junctions and where said repeaters are using at least different frequency bands for said transmission directions in each repeater point to achieve duplex and signal transmission in more than one direction across said signal transmission distance enabled by the signal dampening in the junctions.

3. Analog signal repeater system according to claim 1, wherein

said frequency bands being used by said repeaters to employ frequency conversion enabled by the signal dampening in the junctions.

4. Analog signal repeater system according to claim 1, further comprising an adapter connected to at least one of said repeaters allowing equipment with standardized modulation and protocol that include duplex system standards as in Docsis cable modem standards enabled by the signal dampening in the junctions.

5. Analog signal repeater system according to claim 1, wherein

the repeaters at the junctions are using two frequency bands using two of said repeaters in at least one repeater point where said repeaters each repeat signals on the same frequency in one of said frequency bands to provide full duplex transmission enabled by the signal dampening in the junctions.

6. Analog signal repeater system according to claim 1, further comprising

at least one of said repeaters with said two way transmission to be interfaced to two-way wireless communication device enabled by the signal gain at the junctions.

7. Analog signal repeater system according to claim 1, wherein

the said isolation between ports in electrically accessible physical points consisting of conductor junctions is increased using toroids with magnetic material on at least two conductors while differential signal couplers are connected galvanically through capacitors to at least two conductors on the cable side and while at least one capacitor differentially provides a high frequency low impedance shunt impedance for at least two conductors on the junction side.

8. Analog signal repeater system according to claim 1, wherein

at least one junction is utilizing a single conductor for signal transmission in at least one direction between at least two of said repeaters enabled by the signal dampening in the junctions.

9. Analog signal repeater system according to claim 1, wherein

at least one junction is using at least one conductor for additional signal bypass enabled by the signal dampening in the junctions.

10. Analog signal repeater system according to claim 1, wherein

the said isolation between ports in electrically accessible physical points consisting of conductor junctions is increased using toroids with magnetic material on at least two conductors while differential signal couplers are connected to a wire looping through said toroids on at least said two conductors on the cable side and while at least one capacitor differentially provides a high frequency low shunt impedance for at least two conductors on the junction side.
