What is WLAN dongle?

and dongle is a hardware device with several different definitions. The term may refer to any hardware device that is small and connects to the computer via the port, while other specific meanings include proprietary software security devices; any key that is needed for the operation of the program and connected to the port; Or an adapter cable made to connect a wireless card with the Ethernet connector. WLAN is a wireless network of a local area, a computer network working in a small area, with or without Internet access. WLAN Dongle is a hardware device that allows you to connect separate computers in WLAN. There are several versions of the 802.11 - A, B, G and N - and it is important to compare the standard of network needs and equipment. Different versions work on different frequencies - either 2.4GHz, 5 GHz or both - and at different speeds and computers can be equipped with one or more of them. The 2.4 GHz series may be interference from other devices such as microwaveIt, wireless phones, Bluetooth® devices and child monitors. Generally, newer versions are faster and one piece of equipment on the old standard can slow down the system.

There are requirements for use when employing WLAN WLAN dongle. For example, the Regulation comes from the Federal Communication Commission (FCC) in the United States and R&T Directive (radio and telecommunications) in Europe. Requirements usually relate to security concerns and technical requirements and are listed in Dongle Wlan users. The number of channels will vary depending on where the device works. For example, the channels used in Japan are 1–14, France, 10–13, and in the United States, 1–11.

Two types of configurations with WLAN playground are possible. One of them is Ad Hoc Wlan, which can also be called an independent basic set of services (IBSS) and which allows communication between wireless clients. SomeDongle can have dongle from computers in the group while others have a WLAN PC card. The second type of configuration is the infrastructure mode. Infrastructure mode requires the existence of an access point (AP), which can be a router. It allows communication between wireless and cable clients and also allows the Internet.
