A wireless network device is a type of electronic that can be used on or used to help facilitate a wireless Internet network. There are many different devices that can fit within this definition, and the number only seems to be growing as wireless Internet becomes more and more widespread. One of the most common examples is a router, which converts a fixed Internet signal into a wireless one and effectively creates a network that computers and other technology can connect to without the use of cables or other cords. The things that are actually doing the connecting are also usually considered network devices, though, and this can include anything from computers and phones to e-readers and a wide range of “smart” gadgets. One of the core things that all have in common is the ability to both send and receive a wireless signal, and to connect instantaneously with other components on the same network.
In the world of Internet technology, wireless networks are becoming increasingly common. Not only are they growing in use in homes and offices, but they are also more and more commonplace in public areas like cafes, shopping malls, and restaurants. The networks aren’t usually worth much without devices that can jump onto them and use the signals provided for some other purpose. Computers and many Internet-enabled phones use the signals primarily for browsing and e-mail capabilities. There are many more things that can be done, including storing and capturing data, routing cable television signals, and remotely controlling a range of things from garage door openers to light switches and home alarm systems.
How They Work
This type of device works in cooperation with very specific wireless signals. The specifics tend to vary based on the engineering at issue as well as what it is the signal is being used to do, but in general, every device no matter its end purpose has both a sender and a receiver. The receiver picks up of the signal in the environment, and the sender converts it into something that can then be used for some other purpose within the network.
In order to take advantage of newer wireless signals and technologies, a wireless network device must usually be compatible with and up to date with that specific signal. Technology often changes more rapidly than product development. In many cases this requires upkeep and software installations on the user’s part, and regular updating is usually very important.
Router Capabilities and Signal Division
Wireless network devices can use a range of different signals. Much of this depends on the type of device and its purpose, as well as the sort of router anchoring the network as a whole. 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 these sorts of devices to run simultaneously without interfering with each other. Many households have wireless Internet as well as cable TV with a remote control and web-based data storage, both of which can be seen as basic wireless devices. Using the remote to flick to another channel on a TV does not interfere with using the Internet, any more than checking e-mail on a phone while also streaming video on a laptop would. This is because different devices typically use different bands and signals.
Aside from being a device that broadcasts wireless signals, a network device may also be one that receives signals. Many video game consoles are examples of this sort of device when they’re able to sync with a home's wireless router to allow online game play and other features. Other examples of these 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.
