Whats Better WIFI Or Lan

One of the things I have always wondered is if you could set up a call center on Wifi only so pretty much you could cut all the cabling and other work. I had a friend set it up and was a nightmare and when you are using voip on wifi even worse because Wifi is so unreliable. If you are using WIfi for personal use great it will work provide you are not to far away from the Router. Also the other problem that you have is that hacking Wifi is becoming allot easier then you would thing and allot of people don’t know that, I have a friend that can hack a wep key in about 30 minutes. Best I would say for both business and personal would be Lan connection so many things that you don’t have to worry about.
