In search of an effective medium for modulating 802.3 Ethernet signals over a radio between different NICs there are a few options; The BNC (10base2), AUI, and RJ-45 (10baseT) ports. After extensive research, two of the options are eliminated leaving the AUI port as the best option to use. You cannot use the RJ-45 port because it transmits and receives broadband signals on the same strand of copper wire, thus making radio modulation extremely difficult. Since 10base2 is already modulated and transmits on a given frequency, why not just attach antennas (matched at 50 ohms), and a RF amplifier to each end? Because first, 10base2 sends and receives data on the same wire, thus you would have to split them out to just amplify the TX data path. Otherwise the amp could not switch between transmit and receive modes fast enough. Also, 10base2 uses DC offsets which cannot be effectively transmitted over the air.

Now that we are down to the AUI option, how will can the 2 NICs communicate through their AUI ports over Radios? By using an old 8-bit NIC with the 8320 type controller chip, and crossing over the transmit (TX) / receive (RX) data lines (MAU pins 3 to 5, 10 to 13, shield to shield). These older NICs allow reliable communication without the Control or Collision Detect data lines, reducing the number of radios and bandwidth required. Using 4 RF-link WAVECOM Jr. 2.4 GHz Wireless Video Senders/Receivers, I will transmit the 4 data paths, through the Video ports (which allow 6Mhz of bandwidth each). Once the devices are connected, I will run a network benchmark with just the TCP/IP protocol, and then the IPX/SPX protocol. I will then record, analyze, and graph my results.
