Analog data stream over network.

Torakunsama

Greetings ladies and gents!
I am wandering if it's possible to broadcast analog signals over network(actually it is), to send/receive data.
The idea is to send compacted bites in form of decimals instead of bytes, then convert them on upon reception.
If one day computer technology switches from binary to decimal or more, will the current network infrastructure be useful? Or will optical fibers be required?

Summarizing, I want to have digital data converted into analog, then transported over the network as analog then reconverted into digital on the other end. So 1 bit will equate 1 byte!

Thank you for reading!
