Although the wireless transmission of data is largely taken for granted, when one stops to consider how it actually happens, it does seem magical. There is, of course, a scientific explanation that can be understood by a non-WLAN professional. That explanation is the subject of this blog post.
The first thing to understand is that all wireless transmission is accomplished through waves. Consider the example of when a rock is thrown into a body of water producing circular waves emanating from the point of impact. The waves produced in the medium of water is a repeating pattern comprised of higher densities of molecules followed by lower densities, followed by higher densities and so on. When we hear a sound, we experience the impact of a wave being transmitted through the air. So just like on water (except now in three dimensions) the source of the…
