Sick and tired of going to a music festival and not being able to use your phone because of an overloaded network? Well AT&T is set to improve coverage at large events with their new multi-beam antenna. It works by dividing your phones signal into five narrow parts which will enable up to five times the data traffic. AT&T has said that the new antenna will reduce dropped calls and failed uploads, and is already being tested out at live concerts. Check out the video below to see what this is all about.
