Re: What should I add to my equipment list?
Heh heh...oh yeah...
It'll probably interface seamlessly with the more substantial comms gear, but it probably shouldn't have much range by itself. If it works like a cell phone, space stations and most larger ships will probably have the cell antennas and switching equipment onboard. Comms between people in the same structure will be easy, and comms to another nearby structure probably not much harder...kind of like making an international phone call now. Smaller ships might not be able (and probably won't need) to run comms networks within the ship, and might not allow a direct interface between personal equipment and the ship's comms gear. If it is set up to allow any kind of comms outside of dealing with traffic controllers, emergencies, etc, it would probably require the equivalent of an international phone call from the ship's radio room.
Jamming that augmented reality could be pretty nasty, thinking about it...rather than overlaying the real world with useful information, it would probably actually obscure the real world until it was turned off. It would probably be similar to flashbang in effect. Jammers, of course, are for law enforcement/military use. No one else has any business shutting AR down.
Hope you can find a useful droplet in that brainstorm.
