Hello Armywife,
The wireless transmitter will let you hook up your lights in one place, and leave them sit. No wires to trip on as you move about your room. Then you just flip on the lights, transmitters, and camera, and you are ready to shoot. No need to move them around or otherwise change anything.
Here is a great example:

By the way, I use pocketwizards, but that is because they were the first ones I purchased. There are a lot of different and cheaper wireless remotes.
Good luck,
Frank
