Wireless Ping Pong Scoreboard Answered

I want to make a scoreboard for our ping pong table. I currently have a "prototype" loaded on my arduino. It consists of an LED matrix and two momentary button switches. One button adds a point, one button subtracts a point (just in case) and displays the current score on the LED matrix. The plan is to add another LED matrix and two more push buttons, so that each player will have the buttons mounted on their side of the table, to keep their own score, with the LED matrix mounted on the wall. My question is, does anyone know anyway to make the buttons connect to the arduino wirelessly so I don't have to run a ton of wire? I also currently have implemented debouncing on the input buttons and would like to keep that to ensure that when you add or subtract one point, it really is only one point.

Thanks!
