Overview of Wireless Communication:
Wireless communications is a huge field, encompassing everything from radio and television broadcasting through pagers, mobile phones, and satellite communications. The field of mobile phones is expanding very fast at the same time that standards and protocols are being adopted, used, updated, and sometimes discarded. The other rapidly expanding part of the wireless world is that of wireless local area networks (LANs). Driven by widespread acceptance of the IEEE 802.11 standard, wireless local networking for computers and other devices is spreading rapidly.

Conceptually, wireless communications can be split into two types, local and wide area. A local device is similar to a key fob with a button that unlocks a car, a 900 MHz cordless phone, a radio control toy, or a Bluetooth network. All of these devices operate over short distances, typically just a few meters.

Wide area wireless devices operate effectively over a much greater area. A pager or mobile phone is a good example; you can talk on your mobile phone to any other phone on the planet. These devices' greater range relies on a trick, however: a more elaborate land-based network. A mobile phone doesn't have that much more radio power than a radio control toy. What it does have is a network of carefully placed radio antennas (cell towers); the phone can continue to operate as long as it is within range of at least one tower. The mobile phone device receives service from a wireless carrier, a company that operates the land-based network.
