Why is WLAN Written Instead of Wi-Fi?

Today, we’re going to dive into why you might see the term WLAN used instead of Wi-Fi in certain contexts. You may have noticed that some technical documents or specifications refer to WLAN (Wireless Local Area Network), while many consumer-facing devices or advertisements use the term Wi-Fi. Let me explain the difference and why one might be used over the other in various scenarios.

Understanding WLAN

WLAN stands for Wireless Local Area Network. It’s a generic term used to describe any type of network that allows devices to communicate wirelessly within a limited area. WLAN can be used for a variety of wireless communication technologies, and it is not exclusive to any one technology. Essentially, WLAN is a broad term that describes the overall concept of wireless networking within a localized area, such as a home, office, or campus.

The key thing to understand about WLAN is that it is not tied to any specific protocol. It’s more of an umbrella term that includes different wireless communication standards, including Wi-Fi, Bluetooth, Zigbee, and others. However, when most people refer to WLAN, they are generally talking about Wi-Fi because Wi-Fi is the most widely used standard for wireless communication in local area networks.

Wi-Fi Explained

Wi-Fi, on the other hand, is a specific brand and technology that falls under the WLAN category. It refers to a set of protocols defined by the IEEE 802.11 standards. Wi-Fi is the term that is most often used in everyday conversations and consumer electronics to refer to wireless internet or wireless networking. It has become synonymous with WLAN in the consumer world, even though technically, Wi-Fi is just one specific implementation of WLAN technology.

Why Do We Use WLAN Instead of Wi-Fi in Certain Situations?

Now, you might wonder why we sometimes use WLAN instead of Wi-Fi, especially in technical or formal contexts. Let me explain the reason. In technical specifications, standards, and documentation, the term WLAN is used to maintain clarity and consistency. This is because WLAN covers all types of wireless local area networks, not just the ones that use Wi-Fi technology. For instance, a factory setting might use a specialized wireless network that operates under WLAN standards but is not based on Wi-Fi.

Moreover, WLAN is often used in more technical, enterprise-level discussions, such as in IT infrastructure planning or wireless network deployment. It encompasses a broader scope of wireless technologies, ensuring that no confusion arises when a specific technology like Wi-Fi is not being discussed. By using WLAN, professionals ensure they are referring to wireless networks in a general sense, not limiting themselves to a single proprietary standard.

When to Use WLAN vs. Wi-Fi?

As you may now realize, WLAN is a more formal term that provides a wider scope for wireless networking. Wi-Fi, while technically a part of WLAN, is used more casually and is commonly seen in consumer products like smartphones, laptops, routers, and other devices that provide internet connectivity over wireless networks. You might see Wi-Fi as a branded term in advertising, on the packaging of devices, or in everyday conversations.

Key Differences

As we discussed WLAN and Wi-Fi, it’s important to understand their applications. In related articles, we might have touched on topics like wireless security protocols, Wi-Fi standards like 802.11n/ac/ax, or how WLAN is used in enterprise environments. These topics give you a deeper understanding of how wireless networks operate and how they differ from other types of communication technologies like mobile networks or Bluetooth. By understanding the basics of WLAN, you can see how technologies like Wi-Fi are applied in real-world scenarios, from home networking to large-scale commercial implementations.
