When they talk about channels, they mean like if you have a cordless phone, it says 900mhz, or 2.4ghz or something similar. Other things have channels also, like wireless routers and walkie talkies. Obviously the reason walkie-talkies have different channels is so other people cant listen to your conversation, thats why wireless keyboards have channels also, you probably dont want information magicly typing up on someone elses computer!
Most wireless keyboard manufacturers make thier wireless keyboard/mouse's wireless reciever have only 2 channels. If you do get 3 or more keyboards in the same area, as long as they are far apart enough, you shouldnt have too many problems. The best idea would be to set them up so the first person has CH1, the second person has CH2, and the last person has CH1 again, so both the CH1 keyboards are as far apart as possible. There are also keyboards that have more then 2 channels, but I cant name any off the top of my head. Be careful though if you purchase 2 channel keyboards, as there was a story not too long ago where 2 people had the same HP wireless keyboards on the same channel, and they lived over a football field away, (waaaay out of the range) but due to weather conditions they could see what each other was typing from thier computer.
