What Is a Wireless Network Device?

A wireless network device can be best defined as a network device used to connect computers and computer hardware together without cables, normally through radio signals. The term "wireless network device" itself is very broad, and applies to a wide variety of different devices and technologies. A wireless network device can be anything from a large broadcasting tower to a USB adapter. One example of a common wireless network device is a wireless router. Wireless routers are used not only by at home laptop users, but large businesses and colleges as well.

This type of device works in cooperation with very specific wireless signals. In order to take advantage of newer wireless signals and technologies, a wireless network device must be compatible and up to date with that specific signal. Basic wireless routers are a good example of how devices rely on specific signals.

Wireless routers are available for a range of prices, the difference being largely due to the different signals that the router is capable of using. Wireless routers can operate on band signals such as 802.11a, 802.11b, 802.11g, and 802.11n. 802.11n requires a router with specific built-in technology. It offers a stronger signal and greater range compared to other wireless router networks.

Different bands and signals are also what allow wireless network devices to run simultaneously without interfering with each other. Many households have wireless Internet as well as cable TV with a remote control, both of which can be seen as basic wireless devices. Using the remote to flick to another channel on your TV does not interfere with using the Internet. This is because televisions and wireless routers use two completely different bands and signals.

Aside from being a device that broadcasts wireless signals, a wireless network device may also be one that receives signals. This is what makes the field of wireless network devices so broad. Many video game consoles are even types of wireless network devices, which may be are able to sync with a home's wireless router to allow online game play and other features. Other examples of wireless network devices include USB wireless adapters, wireless cards, some wireless keyboards and mice, and wireless printers. Any device or peripheral that operates by connecting to a wireless network is usually considered to be a wireless network device.
