Are you talking about Ethernet?

If so, you need an analog frontend to interface with the cable, you can not directly connect the cable to the FPGA. Easiest (and only?) option is to use an Ethernet PHY. The PHY handles the analog stuff, speed negotiation, collisions and other stuff. Connect it (or multiple) to your FPGA using the MII (or RMI) interface. Read the PHY datasheet and google for other ethernet information sources.

You need an analog frontend again, with RF part on it. Google Wireless Ethernet PHY.
