The Basics of Wired and Wireless Communications


Electronic products exchange information externally via two general types: wired (Ethernet LAN) and wireless (WLAN). Wired communication uses a physical medium, such as a copper cable or optical fiber, to transmit data. Wireless communication uses radio waves to transmit data.

Ethernet is a wired LAN technology that uses copper cables or optical fibers to transmit data. Ethernet is a popular choice for wired LANs because it is reliable, efficient, and relatively inexpensive.

Wireless communications use radio waves to transmit data. Wireless communications are a popular choice for LANs because they are convenient and easy to install. There are two main types of wireless communications:



This primer has introduced the basics of wired and wireless communications. We have discussed the different types of wired and wireless communications, and the advantages and disadvantages of each type. These topics are essential for understanding how wired and wireless communications work and how to choose the right type of communication for a particular application.
