In theory, Wi-Fi signals are capable of passing through walls and other obstacles relatively easily. However, in reality, some walls are thicker or use reinforced concrete and may block some of the signals. Materials such as drywall, plywood, other kinds of wood and glass can be easily penetrated by wireless signals.

Fiber optic transmission works by converting packets of data such as images, text, emails into a beam of light. This light is sent through a cable to the receiver. Wireless transmission instead converts the data into electromagnetic waves (microwave) and broadcasts it through the air by point to point signaling.

“Wireless” as the term refers, uses air as a medium to send electromagnetic waves or infrared waves. Wireless devices have antennas for communication. Though wireless connectivity is less secured and higher delay than wired connectivity, it is still preferred communication technology for customers. ...
