A long-distance wireless link bridges two remote locations and allows data to travel where it
has never traveled before. A high-speed Wi-Fi link can bring another building online, light
up a remote outpost, or establish a temporary uplink to the Internet. Beaming wireless signals
across long distances makes just about any personal, research, or business task much easier.
The technology has enabled researchers to keep in constant contact with each other and their
test subjects, businesses to save money by connecting multiple offices, and sharing of Internet
access to friends or relatives. Entirely new business models and research methods are being
revealed through long-distance wireless connectivity.
Creating a successful long-distance Wi-Fi link is certainly not unproblematic. Yet, as this
chapter has shown, a good design begins with an accurate survey, Fresnel zone and path loss
calculations, followed by level-headed link planning. If you’re not up to the task mathematically,
use the online link budget calculator at www.olotwireless.net/castella/

Also, remember that most, if not all, of the specifications required for the calculations
in this chapter are available in your hardware manuals, on the manufacturer Web sites, or
through quick customer support phone calls. The task is not without challenges. The reward is
limitless.
