Implementing a hybrid wireless and coaxial cable network
First Claim
1. A home network, comprising:
- coaxial cable;
a first network station, comprising;
a first coaxial connector coupled to coaxial cable;
a matched splitter, connected to the coaxial connector on one side, and on another side having first and second terminals; and
a wireless communications access point, coupled to a first terminal of the matched splitter, for processing wireless protocol communications for transmission and as received over the coaxial cable via the matched splitter; and
a second network station, comprising;
a coaxial connector coupled to coaxial cable;
a wireless communications station, coupled to the coaxial connector, for processing wireless protocol communications for transmission and as received over the coaxial cable via the matched splitter.

Abstract
A home video network, and a home video and data network, utilizing wireless protocol communications over coaxial cable (CX) are disclosed. In the home video network, a main network station (10) includes video processing functionality, such as one or more of a DVD player, personal video recorder (PVR), and a set-top box (STB) for cable or satellite television reception. The main network station (10) also includes a matched splitter (27) that receives coaxial cable (CX) inputs, and provides low-pass filtered and high-pass filtered output. The low-pass filtered output (LF) corresponding to video signals is provided to the video processing functionality (20) and the high-pass filtered output (HF) corresponding to wireless protocol communications is provided to a wireless access point function (22). Other network stations and combinations of functions are also disclosed, including those that utilize a function switch (25) to switch between network communications over coaxial cable (CX) and communications over an antenna (A), in either a single BSS mode or a double BSS mode.
