    It's not so much the technology as the distance. Voyager 1 is 24 billion km away. It transmits at 23W. It takes a 70-meter antenna to receive and decode the signal from that distance. Receive power is -160 dBm (1e-19 watts). A WiFi signal is more than 1e10 times stronger!

    As Voyager 1 moves further away, the transmission rate will need to be further reduced.
