So I'll wait for dscheit to verify that the implants can communicate directly befor I answer.

Radio communications is done by a pretty nifty system of self-healing ad-hoc mesh networks. The radios find another radio that's advertising itself as a relay device, and use it to reach their target. If the target is reachable directly, then they'll talk directly. So it's perfectly possible to reach the person sitting next to you without needing the infrastructure relays, it's the usual situation. There are lots of things that are only reachable by direct communication. For instance, a sign that shows a map of the ship would provide that same information to any receiver in range, but wouldn't relay it out farther.
The radios in most things are very low-powered. The implant radios put out something on the order of a pico-watt, with a bandwidth of a couple gigahertz. that gives them a range of a few meters, for high speed comms, and a bit longer for lower speed ones. It's strictly line of sight, though. A piece of aluminum foil is enough to b block signals.

Gah, I just thought of something else. It's entirely possible that the hijackers are connected in a similar way, possibly using a transmitter one of the hijacker is carrying or using the ship's net after having thrown out everybody else. If that's the case then we'll be swarmed by a unknown number of hijackers no matter what. If we kill or knock out the guard they'll lose contact with him and if we take him prisoner he could actually provide his comrades with a live feed of what we are planning. The only solution to that would be to incapacitate the guard in one way or another and flee from the lounge ASAP.

The bad guys in constant communication is an element of nearly every thriller made in the last 1000 years ofr so.
