Abstract :
Free wireless Internet. It seems to be everywhere: hotels, cafes, airports, and even on the in-town street lights in my city. Free internet access ports are all around us, yet you, like me, probably pay to bring it into our home. Each month we shell out money for dial-up, digital subscriber line (DSL), or cable-based Internet service when all that most of us really need to do is to sign up for a free e-mail account and construct a simple high-gain antenna.
