What communication device could be used over several kilometers?

This is for my book.



I'm in the idea process for it, and I was thinking that a group of them could start walking separate ways and keep in contact through some sort of communication system. What is it that, say, bus drivers and police use to keep in contact really far away?



Can't find a good category to post this under! xDWhat communication device could be used over several kilometers?
What about some sort of native alien creature that they tamed and trained to relay messages? Something small, fast, with wings maybe?
Thanks for the best answer! :)

When i saw that they were on another planet, i just knew that some alien creature would be the best for the job! Whatever you're writhing, i'm sure it'll be awesome! :D
