I have a building that is cabled with CAT3 (no condiuts) and it would cost too much to recable it.
I need to run high bandwidth from the ground floor server room up to the 2 upper floors.
Wireless is an option that I would like to avoid: the signal is not very good running through the floors of this building - apparently there's lots of metal in the floors - and the security is not ideal.
What I thought to find is a wideband modem device that I could set at each end of the CAT3 cabling to get up to 40+Mbps through the cable. Most cable modems will do this speed, but can't be connected in a point-to-point mode as they require a big expensive access device on one side (normally an ISP).
A basic diagram of what I plan is:
[server room switch]<--CAT5 UTP Drop-->[modem device]<--Existing CAT3 to upper floors-->[modem device]<--CAT5 UTP Drop-->[LAN Switch]
What device can I use as the modem device in this diagram? Has anyone done this before? What hardware would you recommend to do this with a limited budget?
