Invisible environment:

The main difference between wired and wireless networks depends on the Communication environment. The wired networks use cables to transfer data. As for wireless networks, the function of Radio Frequency signal (RF) and the light signal transfer data through the air. This article debates common concepts to all types of wireless networks with emphasis on the basics of RF and light signals.

Internet access:

Internet access shows one of the most important reasons for the installation of a wireless network in contact with the Internet sharing a single high-speed. By this kind of configuration, every member of the family or in the office of small business access to easily share a single high-speed modem or cable modem (DSL).
