Chapter 1. ✓ Start Here

For the past several years there has been talk of a “wireless revolution” that is going to hit at any moment. And year after year, that moment has come and gone with plenty of wires and no revolution. That is, until now. It was a few years late in coming, but the wireless revolution has begun in terms of traditional desktop computers, household appliances and—more importantly to this book—mobile handheld devices. Sure, wireless mobile phones have been around for a while now, but it wasn't until recently that technologies converged to give us multipurpose handheld devices.

Before I get too carried away with this talk of a revolution, allow me to point out that we're still in the very early stages of the wireless revolution. Wireless short-range networks have made it possible for us to roam around the house with a constant Internet connection, as well as drift into and out of spheres of connectivity in public spaces. The next level of wireless Internet access is now visible on the horizon, where high-speed wireless connections can be made across miles of separation. But this applies to broadband wireless connectivity, which doesn't entirely correlate to handheld devices. More specifically, mobile phones use a different type of network connection for shuttling voice and data, as compared to a notebook PC that is concerned with only a high-speed data connection.
