Many users see the "WLAN" logo when connecting their mobile phones to a Wi-Fi network. But what exactly is WLAN, and how does it relate to Wi-Fi? Is there a mistake in your phone's system? Don’t worry—today, we’ll break down the differences between WLAN and Wi-Fi so you can understand them clearly.
First, let’s look at what WLAN and Wi-Fi actually mean. WLAN stands for Wireless Local Area Network. It refers to a network that uses wireless communication technology to connect devices and allow them to share resources. In simpler terms, it’s a type of local network that doesn’t require physical cables. WiFi, on the other hand, is a specific technology used to access a WLAN. Think of it like this: WLAN is the big network, and WiFi is one of the ways to connect to it.
When it comes to coverage, WiFi has a more limited range compared to WLAN. Typically, a WiFi signal covers about 90 meters, and the strength decreases as you move away from the router. This is similar to Bluetooth, where distance affects connectivity. In contrast, WLAN can cover much larger areas—up to 5 kilometers in some cases. This makes it ideal for larger spaces like offices or campuses.
Another key difference lies in the standards. WiFi is a certification standard developed by the Wi-Fi Alliance, ensuring compatibility between devices. While WLAN is a broader term for any wireless local area network, WiFi is one of the most common technologies used within that network. So, if your phone is Wi-Fi certified, it means it supports the WLAN standard.
In summary, while both WLAN and Wi-Fi are related to wireless networking, they serve different purposes. WLAN is the general concept of a wireless network, and WiFi is a specific, widely-used technology that operates under the WLAN umbrella.
