One of the more futuristic technologies being explored by the Warriors is known as LiFi. The technology uses light to transmit data, letting users do things like stream Internet video to a TV from a light in the ceiling.
LiFi works by attaching an Ethernet-wired ceiling-based device to a standard LED light. The data about to be beamed through the air are sent to that bulb, which is instructed to flicker millions of times per second to communicate a signal — kind of like an extremely speedy morse code. The light signal — which looks identical to a normal light — is picked up by a receiver.
In the case of the new Warriors complex, LiFi could be implemented in lampposts outside the arena, passing information to people as they walk nearby. The beams could act like the beacons inside the arena, distributing content to passersby.
