A Wireless Network, Also Known as Wi-Fi, Explained

The term “wireless networking” refers to a method of connecting nodes in a wireless network by using radio frequency (RF) connections. People, businesses, and telecommunications networks are increasingly using wireless networks with the assistances of engineering wireless services.

People often question themselves, “What is a wireless network?” despite the fact that they can be found practically wherever people live and work. An analogy to this is that many individuals mistakenly assume that Wi-Fi and all other wireless technologies are interchangeable. It is important to note that while both technologies share the same radio frequency (RF), Wi-Fi is specific to the wireless protocol defined by the Institute of Electrical and Electronic Engineers (IEEE) in its IEEE 802.11 specification and its amendments, whereas there are many different types of wireless networks that can be used across a range of technologies (LTE, Bluetooth, 5G).

What exactly is Wi-Fi, and how does it function?

Wi-Fi networks use radio waves to communicate with one other (cellular phones and radios also transmit over radio waves, but at different frequencies and modulation):

  • Access points (APs) in Wi-Fi networks often promote the specific network to which they give connectivity. A Service Set Identifier (SSID) is what you’ll see when you look at the list of networks that are available on your phone or laptop (SSID). The AP transmits this information via so-called “beacons,” which are radio waves. Feel free to join if this is the network you’ve been looking for”
  • An access point (AP) may connect with a client device by receiving messages from it that ask for network access and (if security is enabled) provide relevant credentials to confirm they are authorised. Users may send messages to the AP seeking to join and giving proper credentials to confirm they are authorised to join the network if security is enabled. To explain these processes, the phrases association and authentication are used. The device will be unable to join the network and will be unable to connect to the access point in the future if even one of these steps fails.

You may protect your network by employing managed Wi-Fi and security, which helps to prevent unauthorised users and data from damaging your devices. When you use Wireless Access Points of engineering wireless services to monitor your network, you get a complete image of the devices that are connected to it. Also compatible with Security Fabric, it also offers cloud access point management and comes with a dedicated controller.
