Finding the right Wireless for you

Licensed
Getting an FCC license is a relatively simple matter. Generally speaking,
there are two types of licenses, regional and fixed, point-to-point.
Regional licenses get all the publicity because of the millions that carriers
bid at FCC auctions in order to control certain frequencies in their markets.
By contrast, the total cost for a point-to-point, private-user license is
under $3,000, and it's good for ten years with options to renew.

Un-Licensed
Radios in the unlicensed bands ("unlicensed, license-free, license-exempt", et al) are very different from radios that are licensed. It's like comparing a motorcycle to an automobile. They each have particular merits, depending on your purpose.

Wi-Fi
Wi-Fi was originally a brand licensed by the Wi-Fi Alliance to describe the embedded technology of wireless local area networks (WLAN) based on the IEEE 802.11 standard. As of 2007, common use of the term Wi-Fi has broadened to describe the generic wireless interface of mobile computing devices, such as laptops in LANs. The term Wi-Fi was chosen as a play on the term "Hi-Fi", and is often thought to be an abbreviation for wireless fidelity. Wi-Fi and the Wi-Fi CERTIFIED logo are registered trademarks of the Wi-Fi Alliance, the trade organization that tests and certifies equipment compliance with the 802.11x standards. Common uses for Wi-Fi include Internet and VoIP phone access, gaming, and network connectivity for consumer electronics such as televisions, DVD players, and digital cameras.
