LightAnchors author here!
Hey all,
I am an author on the paper. This is a great discussion - very exciting ideas shared!
The main idea is to use a LightAnchor to transmit a UID or an IP and then use it to open a connection outlet with a higher throughput. In some applications, the ID is enough to link an interface. In future however, we are looking to develop higher bit rate systems (currently we can do up to 120 bits per second).
