What Is Wireless Adapter and How to Find It on Windows 10? [MiniTool Wiki]
What is the wireless adapter? A wireless network adapter is a computer hardware component designed to enable computers to communicate wirelessly over a network.
The function of it is to expand computer functionality by connecting to the computer via expansion card devices, or cards, such as memory cards or PC cards. You can also use a USB port on the computer or an internal adapter already contained within the computer to connect the wireless network adapter.
Wireless network adapters follow the IEEE 802.11 standard, although different versions of the standard allow faster speeds. This version is indicated by a lowercase letter at the end of the standard name. The first version of the protocol, "A", is referred to as 802.11a.
Generally speaking, the later the letter falls in the letter, the higher the version of the protocol: for example, 802.11g, which supports speeds up to 54 megabits per second (54Mbps). However, newer 802.11n versions use multi-stream technology to double the speed to 108 Mbps.
The wireless network adapter picks up the signals broadcast by the wireless network. Wi-Fi "hotspots" or locations typically broadcast radio waves through areas ranging from 75 to 150 feet. A wireless network adapter within range will pick up the signal and establish a wireless connection.
There are many types of wireless network adapters that can be widely used. For example, desktop users may be well suited for PCI adapters that are specifically designed to fit the expansion slots available inside the desktop.
These adapters typically use a large external antenna to communicate with the router to draw power from the desktop's power source.
In contrast, PCMCIA adapters are only designed to fit into the expansion slots of older laptops, and sometimes use external antennas to generate strong radio waves (PCMCIA adapters with internal antennas can achieve the same goal, but lower radio power).
However, by far the most popular is the Universal Serial Bus (USB) adapters. These small, easy-to-use adapters are designed to plug into a computer's USB port only, work with laptops or desktops, and typically support plug and play functionality on both Windows and Mac computers.
Wireless network adapters have several advantages. The most important of these benefits is increased liquidity. By releasing the laptop's cable to an Internet connection, a truly wireless experience can be achieved.
In addition, desktop computers can be placed anywhere in the home without the need for complicated wiring work, drilling holes and meandering Ethernet cables along the backplane. Finally, wireless adapters eliminate the physical limitations of wired routers by allowing up to 254 wireless connections simultaneously on a single router.
The price of wireless network adapters varies widely. Depending on the supported 802.11 protocol version and the design type of the adapter, the price usually ranges from $10 to more than $100.
USB wireless adapters are usually the cheapest, with some models of 802.11g adapters priced at $9.99 at major retailers. The price of a more typical 802.11n adapter made by a well-known manufacturer may be close to $50.
Models designed for semi-permanent installations, such as PCI adapters, are more expensive, and the latest and most powerful version costs up to $100.
