RF Remote

I am looking for a small RF transmitter hand held (as in remote control) needs minimum of 20 buttons that I can interface to control a scoreboard at an Indoor Soccer Facility. I built the scoreboard using the Arduino and using several IR receivers. The problem is the range on the IR is not working to good.
Any ideas?
Thank You

I have recently built a wireless remote control for model trains using nRF24L01+ 2.4GHz transceivers. Once you get the wireless comms working (which is not difficult with this Tutorial) you can send any data you like. It will be enormously faster than IR - and should have much better range.
