In part 1 of this series, I dealth with faster than light travel in a semi-non-magic fashion. I briefly mentioned the possibility of FTL communication using a similar technology, namely a form of warp wave packet.
Just like with many communication technologies today, physical limitations are imposed. One of these is the fact that unlike radio transmission, which is omnidirectional, warp packets (or solitons) are directional and can therefore only be used in point-to-point communication.
What’s more, due to energy dissipation, the packets degrade quickly. Therefore, relay stations are needed to secure stable and predictable communication. In essence, one needs to build up a form of warp internet infrastructure in the region where one wants FTL communication.
This opens up many plot options. In on story, the early settlers arrive at a planet before the relays are built and are effectively isolated from communicated with other colonies.
Building (or repairing) the relay network may be challenging and allows for reasons to go on missions into remote areas.
Finally, in battle it is a major advantage to be able to communicate FTL and being able to damage that ability can be a decisive advantage.

Definitely Ansible territory, although I think they’re supposed to be made as entangled sets. Of course Orson Scott Card used the fictional philotic science.
