Abstract

A premises, connected to receive broadband service(s) and also connected to a cable system, is provided with a broadband interface which connects to in-premises cabling which is coupled to consumer receivers such as a television sets, PDAs, laptops. Connected to the broadband interface is an adjunct device which channels broadband, data and voice signals supplied to an in-premises wireless system as distinguished from the signals supplied to the cable connected consumer receivers. The adjunct device formats the broadband and voice signals or any broadband service into packet format suitable for signal radiation and couples them to the in-premises coax cabling, via a diplexer, at a first selected location. At a second cable location a second diplexer, connected to the cable, separates the broadband, data and voice signals and couples them to a signal radiation device (i.e., an RF antenna or leaky coaxial cable) which radiates the signal to the immediate surrounding location. Various devices, near to the second cable location for specific services, receive the wireless signals (i.e., broadband, data and voice) from the radiating antenna.

Claims

1. A method of distributing broadband signals within a premises, comprising the steps of:

packetizing incoming broadband signals at a first frequency into RF frequency signals;

modulating the packetized RF frequency signals at a second frequency; and

providing the packetized and modulated RF frequency signals to in-premises cabling for distribution to signal radiation devices located within the premises.

2. The method of claim 1, further comprising a step of:

transmitting the RF frequency signals on cabling used within the premises for cable television signal distribution.

3. The method of claim 1, further comprising a step of:

using the signal radiation devices to radiate the RF frequency signals, the signal radiation devices comprising radiative antennas coupled to the cabling near receiving equipment.

4. The method of claim 1, further comprising a step of:

using the signal radiation devices to radiate the RF frequency signals, the signal radiation devices comprising a leaky cable of the in-premises cabling.

5. The method of claim 1, further including a step of:

supplying the broadband signals by external cable.

6. The method of claim 1, further including a step of:

supplying the broadband signals by fixed wireless.

7. The method of claim 1, further including a step of:

supplying the broadband signals by DSL.
