Wired technology

Since year 1900, wired technology become famous because of the telephone network. Using physical wires means that electronic singles are being transmitted over a metal conductor. This is a good way to transmitting and receiving information. For purposes of this article, “wired” refers to copper wiring and does not include fiber optic technologies.

Wireless Technology

Wireless technology means send information through the air, likes microwave, infrared and other to transfer data without wires between communications devices. Wireless signals were fist used in transmitting AM and FM to television and radios in the early 1950's. The military has been using "line of sight" micro-wave towers for decades. Everyone knows the most common wireless technology: cellular phones. However, this technology has several problems. The table below portrays the pros and cons of wireless technology.


Pro's

High Life Expectancy

Con's

Un-reliable - affected by other wireless signals (portable/cellular phones, microwaves, etc)

Price

Signals can be easily intercepted

Speeds are much slower than wired
