Cable TV over 802.11G

Techie5 · 08-10-2007, 10:05 AM

Hello, I am new to this forum.

I need to setup a wireless network at home. I am attempting to stream cable tv over 802.11G from 1st floor to 2nd floor. I have cabletv to cat5 adapters. What I need to do is get two 802.11G bridges to talk directly to each other(point to point). The problem is, they do not have line of sight. Is it necessary to buy an industrial strenght wireless bridge for this or will a typical home wireless bridge suffice?

I don't think this is possible the way you have it set up. Cable TV (at least analog cable) is not packet switched. Therefore, the wireless bridge has nothing to transmit.

Typically, wireless networking does not require line of sight.

Well, I figured if it is possible to transmit cable TV over cat 5 cables, I could just plug the cat 5 cable into a wireless bridge and have it automatically transmit whatever is coming in to the other bridge. There are no settings that would allow me to make the bridges function in this way?

Also, I realize the 54mbps max throughput rate wont be enough to keep the quality high. I just want to see if it is possible at all. Maybe in the future, throughput rates will be high enough to maintain the quality.

It might be possible when you're going from analog to analog just using the cable, but any network hardware you would connect it to would simply not interpret the signal, since there's no way to tune it.

What might be a very viable option for you is a ethernet-compatible tuner. It's really only ideal if you want to watch any two TV stations simultaneously on any computer in the house, but it'll only work on a normal TV if you're using the video output of a computer. I suppose the only way around this is if you have a piece of A/V equipment that can decode a stream. I'm pretty sure they exist, but a used laptop with an S-video output would probably be cheaper.

One major plus of this setup is that it allows you to tune HD video at full resolution.
