All things pertaining to wireless and RF links

How can I make one Arduino Uno (which is connected to a switch) tell another Arduino Uno that its been pushed and then make an led turn on, on both Arduino's. I dont really want to use the xbee because it would be connected to the internet but I need some range, about 150 feet. If someone could give me the code for both, I would appreciate it.
