GPS api and Skynet api...

first of all… Sorry I'm not good at english…
cuz I'm korean…T_T

I thought "How can I increase the GPS range?"
and then I saw the 'Skynet api' which increase rednet.send's range…
but I know there's a problem;Skynet api can't calculate about distance…
so, Is there any idea to solve that problem?
at least, How does rednet.receive() function calculate about distance?

thanks for read my humble question…

In the config there is an option that says: rednet-,ax (or something like that…), go there and put there 9999999999999999999999, that should give you enough range :P/>/>

PS: the config is at .minecraft/config/computercraft
