The use of wireless technology has been increasing greatly in the last few years. Now there is wireless gaming, audio, and video. Wireless gaming and audio is probably the most used out of all the wireless technology out there. Except for wireless phones and computers. The main purpose of wireless gaming is to connect with other users in the world without the hassel of a lot of cables.  A person will often have a wireless internet hook up. This works by plugging in a wireless internet adapter into the back of the console into the ethernet cable hook up slot. You need a router in order to have wireless internet throughout the house.  Another thing that is wireless is audio. Bose makes an excellent wireless surround sound system. The way this works is you first need to sync in all the speakers so that it is with the main sub and circuits. Then all you do is set the speakers where you want them and listen to some great surround sound.
