What is Wireless Computer Networking?

Wireless is a more modern alternative to traditional wired networking that relies on cables to connect networkable devices together. Wireless technologies are widely used in both home and business computer networks.

Types of Wireless Network Technologies

A variety of technologies have been developed to support wireless networking in different usages including:

• Wi-Fi, especially popular in home networks and as a wireless hotspot technology
• Bluetooth, for low power and embedded applications
• wireless home automation standards like ZigBee and Z-Wave

Advantages of Wireless over Wired Networking

A wireless computer network offers several distinct advantages compared to a wired network but is not without downsides. Advantages of wireless technology include mobility (portability and freedom of movement) and elimination of unsightly cables. Disadvantages of wireless include additional security concerns, plus the potential for radio interference (due to weather, other wireless devices, or obstructions like walls).

How Wireless Works

Wireless technologies employ radio waves and/or microwaves to maintain communication channels between computers. While many technical details behind wireless protocols like Wi-Fi often aren't important to understand, knowing the basics can be very helpful when configuring a network and troubleshooting problems.
