The protocol uses time division multiplexing to solve the hidden node problem (https://en.wikipedia.org/wiki/Hidden_node_problem https://en.wikipedia.org/wiki/Hidden_node_problem) where two nodes can be transmitting at the same time causing a collision. They also mentioned that they didn't tilt the solar panel to follow the sun for reduced complexity, cost, weight and the risk of failure of a servo system. They don't know what the speeds will be but 'as fast as 3G' was the marketing line. To me it seemed like this project still had some large hurdles to viability but it was cool none the less.
