Abstract

A method for transmitting data signals between nodes in a networking system having one or more signal splitters. The method comprises transmitting wired and wireless data signals between nodes at a same frequency at which the effective isolation of each signal splitter at that frequency is substantially less than the specified effective isolation of each splitter. The invention also provides a wired networking system comprising one or more signal splitters. Each node in the system is configured to transmit and receive wired and wireless data signals over the system at a same frequency at which the effective isolation of each splitter is less than the specified effective isolation of each splitter.

Claims

1. A method for transmitting data signals between nodes in a networking system, the system comprising one or more signal splitters, each signal splitter having a nominal frequency and a specified effective isolation, the method comprising transmitting wired and wireless data signals between nodes at a same frequency, the effective isolation at the frequency being substantially less than the specified effective isolation of each splitter.

2. The method according to claim 1 wherein the frequency is a frequency specified by any one of the protocols 802.11a-e and Hiperlan-2.

5. A node set up box (STB) for use in the system of claim 1 or 2, comprising

(a) a coax interface having a LAN base chip;

(b) a wireless interface having a wireless base band chip;

wherein the STB is configured to transmit and receive wired and wireless AV signals at the same frequency, the effective isolation at the frequency being less than the specified effective isolation of each splitter in the system;

and wherein the coax LAN base band chip interfaces with the wireless LAN base band chip.

6. A node set up box (STB) for use in the system of claim 1 or 2, comprising a MAC processor, wherein the STB is configured to transmit and receive wired and wireless AV signals at the same frequency, the effective isolation at the frequency being less than the specified effective isolation of each splitter in the system;

and wherein the same MAC processor and the same protocol stack are used for wired and wireless transmission.

7. A node set up box (STB) for use in the system of claim 1 or 2, comprising

(a) an RF chip for wired transmission, wired reception, wireless transmission and wireless reception;

and

(b) a PHY transmitter for wired and wireless transmission;

wherein the STB is configured to transmit and receive wired and wireless AV signals at the same frequency, the effective isolation at the frequency being less than the specified effective isolation of each splitter in the system.

8. The node STB according to any one of the previous claims wherein the frequency is a frequency specified by any one of the protocols 802.11a-e and Hiperlan-2.

3. A wired networking system comprising:

(One) one or more signal splitters each signal splitter having a nominal frequency and a specified effective isolation; and

(Two) two or more nodes, each node being configured to transmit and receive wired and wireless data signals over the system at the same frequency, the effective isolation at the frequency being less than the specified effective isolation of each splitter.

4. The system according to claim 3 wherein the frequency is a frequency specified by any one of the protocols 802.11a-e and Hiperlan-2.
