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 large number of technologies have been developed to support wireless networking in different usages. Mainstream wireless technologies in use include:

Other technologies still under development but likely to play a role in wireless networks of the future include 5G cellular Internet and Li-Fi visible light communication.

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).

Other Applications of Wireless

Besides home networking and Internet connectivity, wireless is being integrated into an increasing number of places where it wasn't used before. Watches, refrigerators, and many other personal devices - sometimes even clothing - are gradually being fitted with wireless communication capabilities. How useful all of this technology is for society remains to be seen.

Wireless Network Hardware

To build or tap into a wireless network requires certain types of computer hardware. Portable devices like phones and tablets feature built-in wireless radios. Wireless broadband routers power many home networks. Other kinds of equipment include external adapters and range extenders.

Wireless network equipment can be complex to develop. Consumers recognize the brand names of wireless routers and related home network gear, but many do not realize where the key internal components of these boxes come from.
