In Jump Temp, there is no FTL communication. That is, aside from a starship. Starships in the process of jumping can send and receive radio signals on both ends of the jump. This makes data channels between star systems possible but only when there’s a constant and unbroken stream of ships traveling in between systems.
It might be practical for planets to have small fleets of jump drones that communicate with nearby star systems. This would help to get vital information in between systems. Commercial endeavors may even deploy their own arrays of jump drones and rent out their communication bandwidth to the highest bidder.
However, there’s another wrinkle to light speed communication. Even at the speed of light, radio takes minutes to travel between earth and the perimeter of where a jump drive can start to deliver the ship faster than light.
That means that when a ship enters a system it could take several minutes for anyone to hear their communications.
That makes Star Trek style video chat impractical except at distances of less than 400,000 kilometers (about 1 light second). The vast majority of communications would likely be similar to text messaging.
