| Is it possible... ..to wirelessly send both data and a cable tv signal?
Ive got an issue of expense trying to get cable tv and internet to a house that is about 1500 feet from the point of service (the street).
I could setup the demarcation at the road and setup the modem and wireless there and receive it at the end point (house) location, but could this be done with the full signal off of the coax?
Let me know if this is a confusing question, Im not sure how to word it; or if this is the wrong place to look for answers 
thanks,

| There are two answers to this:
The Cable Company's answer: "No"
The technical answer: Most cable TV providers are using analog/digital cable (and very select few are using some form of IP-TV) to the set-top-box. The problem with this is pretty simple: TCP/IP can easily be transmitted wherever you want, using what ever media (fiber, copper, wireless, microwave, BPL, etc) -- TCP/IP is a protocol - it doesn't care how it gets from point-A to point-B... Digital cable TV uses (well most) QAM modulation which is definitely NOT TCP/IP, meaning it can't be transmitted nearly as easily and requires specific equipment to do so. You *CAN* re-transmit/extend your demarc wirelessly but you'll have the find equipment that handles the broadband 1Ghz modulation (required for digital, HD and VOD signals) -- this is NOT an easy task, nor a cheap one - in fact I seriously doubt that any sort of medium-range QAM transmitter is going to be even legally usable without FCC licensing.
Essentially, extending your internet wireless = Easy, extending Analog/Digital Cable = you're going to mortgage your house to purchase this equipment....
I may be cheaper to just hire a contractor to trench a conduit to the pole...

You need up to 1Ghz. With a loss of 64db even with RG-11, you're going to need amplification. Probably two amps and some passives, in fact. If you could run hardline you might be able to get away with one amp. |
