Wireless connectivity issues
Wireless networks are becoming more and more ubiquitous around the world as they free us from many of the technical difficulties of wired networks. However, they also introduce a number of complications that must be considered. In this section, we will explore some of the most common issues that technicians face in wireless networks.
Physical layer issues
Wireless signals face even more obstructions than signals in wired media, as these wireless signals propagate in unguided media. Radio frequency (RF) signals between Access Points and client devices often have to propagate through various objects and materials, including concrete walls, glass, and other electronic items. While propagating through these materials, these signals may undergo phenomena, such as reflection, where the signals bounce off certain surfaces such as metallic objects; refraction, where the signals bend due to traveling through two dissimilar media; and absorption, where the...
