Sky Fortress

Hello everyone (:

Before anything I want explain why am I asking you about this (:

I'm on a little project with my friends in a LAN server and we making a Sky Fortress or Sky Ship it's a combination of RP2 ( Red Power 2 ) and CC (ComputerCraft ) all the stuff about RP2 and somethings of CC too, but we're trying to do some wireless turtles and here is the question :

How I do a Control System ? ( With The Computer )
How I increase the wireless field ?

Please Remember : It's Like A Explorer On NASA The Mission Is Down,Dig Ores,Stone,Food then go back (:
Thanks For Reading

You can increase the range of Rednet modems in your ComputerCraft configuration file.

We're not coding for you.

You can also have a "relay satellite", perhaps using Leo Verto's LeoSat program (some of us have already programmed for others in general, which includes you, if you're willing to look for the programs that suit your needs).
