What is wrong with the WoC scheme in the following options?

The WLAN and CATV signals are mixed by the signal combiner and input to the existing CATV cable, and transmitted to the CATV coaxial shielded cable.

In the room, finally separate the signals through the splitter panel to achieve indoor wireless network coverage and TV signal transmission.

The overall construction of WoC does not need to be changed too much, the construction impact is negligible, and the wireless coverage is better. It is excellent in wireless system transformation projects.

Obvious

Signal combiner and WoC panel, need to be customized separately from the partner

At present, the cable commonly used by CATV is SY(W) V75-5 coaxial cable, which is specially produced for cable TV. The transmission frequency of 2.4G is very small, so the distance from AP to terminal panel can be longer, but it is recommended not to exceed 500 meters
