The purpose of the paper is to attempt to consolidate all the relevant information regarding the numerous methods to wirelessly connect geographically dispersed systems. It is not the goal of this paper to make the reader an expert on any of these methods, since that would take several books. Instead, by giving a brief overview of each method, the reader can choose for himself which method to focus on for a given application.

One thing that cannot be said about wireless Wide Area Network (WAN) technology is that it lacks variety. There are so many possibilities it is mind-boggling. Unfortunately, the truly ubiquitous wireless WAN solution that meets most telemetry needs remains elusive. Until that time comes, we will have to deal with coverage and technology issues specific to location.
