-The main difference between MAIANA&trade; and every commercial transponder is that it's a self-contained unit, and thus its performance is 100% repeatable. The entire transponder circuit, the GNSS and all antennas are in the same housing. The design has been validated by fabricating _over 100 units_ now (February 2022).

 So with all the core functionality kept outside and under tight control, the only other thing we need is power and data connections. Now, what's the most common cable that can carry a few signals 50 feet away? If you guessed "Ethernet", you guessed right.
