All You Need To Know About WLAN: Definition and its Working
With innovative and new technologies in every sector, then whether it is the healthcare industry, e-commerce, or marketing, and much more success is like stepping ahead. People are getting more attracted to digitalisation. New things introduced in WLAN are helping people in many ways, making it beneficial to society technology and the digital transformation.
Here we are going to have all about WLAN. Wireless connectivity is the most effective and productive technology that’s making people success. WLAN are wireless networks that use radio waves.
What is WLAN?
Defining the wireless local area network, it is the distribution method of two or more devices by the use of high-frequency radio waves. An access point to the internet is used often. The biggest problem of the internet connection is that it is limited to some distance.
However, in WLAN, it allows us to move around the coverage area then whether it is your home or office, but the best part of it is the network connectivity remains excellent. These wireless networks are being used since the last few years, but back in the 1990s, WLAN was very expensive. They were only used when the wired connection was strategically impossible. But coming to the late 1990s, the wireless networks were replaced by IEEE 802.11 standards in various versions.
Significantly the price of WLAN decreased. Sometimes people get confused WLAN with Wi-Fi. Wi-Fi and WLAN are not the same things where Wi-Fi refers to wireless communication; on the other hand, WLAN uses that connection in a local area network. That’s why we call it the wireless local area network.
How WLAN works?
As we said that WLAN is a wireless local area network, the communication is done without wires. The radio, infrared, and microwave transmission are used in WLAN to transmit data from one place to another. WLAN can further be attached to the already existing more extensive network that is the internet.
Nodes and access points are two things that WLAN consists of; a node is a computer or peripheral that has a network adaptor, which is in WLAN’s case that has an antenna. Transmitter and receivers functions are performed by the access point that transmits or receives between nodes or themselves or between nodes and other networks.
Technologies that are used for the WLAN data transfer can be:
• Direct sequence spread spectrum (DSSS)
• Frequency-hopping spread spectrum (FHSS)
Infrared technology is a very high frequency to carry the data. The range of the wireless local area network can be anywhere from a single room to an entire campus, so security is needed. Various security systems are there to protect your WLAN. The security is required because the WLAN signal has no physical boundary limitations. They are prone to illegitimate access over network resources that can affect the private and confidential data.
Besides WLAN advantages, security has also remained a major concern in WLAN’s around the globe. Problems for WLAN can be: session hijacking, unauthorized access, denial of service attack, IP and MAC spoofing, and counter these threat WLAN security systems work well.
