Understanding Wireless Networking: How Does It Work?

Wireless networking is a computer network that uses wireless data connections between nodes in the network. This type of network allows devices to remain connected to the network while disconnecting without disconnected cables. Wi-Fi signals are amplified by access points, meaning that a computer can be far from a router but still connected to the network. You can connect to an existing network through a wireless access point or communicate directly with other wireless computers. Administrative telecommunications networks are generally implemented and managed through radio communication at the physical level (layer) of the OSI model.

A global area network (GAN) is a network used to support mobile telephony over an arbitrary number of wireless LANs, satellite coverage areas, etc. Each standard varies by geographical range, making one standard more ideal than another, depending on what you're trying to achieve with a wireless network. All other clients on the network (computer, printer, mobile phone, tablet, or other device) connect to an access point to access a larger network. The only difference between a wireless and a wired network is that the wired network uses cables to connect devices to the Internet or to another network, such as laptop or desktop computers. As wireless networks have become commonplace, sophistication increases through the configuration of network hardware and software, and greater capacity is achieved to send and receive larger amounts of data more quickly. Wide-area wireless networks are wireless networks that generally cover large areas, such as between neighboring towns and cities or between cities and suburbs.

Metropolitan area wireless networks are a type of wireless network that connects several wireless LANs. It can connect to all the computers in this office on a network to allow the use of each department. The only terminal problem occurs when a node in a network is unable to send because of interference between channels of a node that is in a different network. The most obvious benefit of using a wireless network is that it keeps devices connected to the network and, at the same time, allows them to move freely without cables. Conversely, building a network by dragging cables through the walls and ceilings of an office can be laborious and costly.

This is called a service set identifier (SSID) and is what users see when they check the list of networks available on their phones or laptops. The most popular wired networks use cables connected to an Ethernet port on the network router and at the other end to a computer or other system. Space networks are networks used for communication between spacecraft, usually in the vicinity of the Earth.
