If you read some articles about wireless work, you might frequently see these two terms: WLAN and WiFi. They look very similar, you might wonder: are they the same thing? These terms are very common in our day-to-day activities. Sometimes, different brands of mobile phones use WLAN or WiFi to refer to wireless network settings.
To better understand these two terms, here we will offer a detailed guide. We will compare the differences between WLAN and WiFi from several perspectives.
What Is WLAN?
WLAN stands for Wireless Local Area Network. As the name implies, it is a type of wireless network that allows several devices to communicate with each other via radio technology. Besides, these devices can freely transmit data.
Be aware that a WLAN network has a certain coverage, it is widely used in homes, classrooms, offices, or other small spaces. Unlike wired connections like Ethernet cables, you can still get a stable connection as long as you are within this area.
Types of WLAN
Infrastructure mode: It is the most common operation mode for wireless networks. Under these configuration settings, devices will communicate through a wireless access point (WAP).
It can manage all the available traffic. In addition, it will make sure all the devices communicate successfully and guide the data travel to the right destination.
Ad Hoc Mode: A wireless ad hoc network is also a kind of network that uses peer-to-peer (P2P) mode. All the devices within this coverage can automatically detect each other and communicate, no access points are needed.
What Is WiFi?
To learn more about the difference between WLAN and WiFi, here we will get to know the definition of WiFi. In essential, WiFi is a type of WLAN network that is based on the IEEE 802.11 standards. It might be the most commonly used wireless network in the world, and most mobile devices can connect to WiFi such as your phone, laptop, games console, and smart TV.
All the data are sent back and forth between these electronic devices via the radio waves. Generally, the coverage of a WiFi network depends on its router. That’s why setting your router in the right place is very important and it will greatly influence your connection.
No cabling is needed, you can just enter the password and connect to the WiFi network within a few seconds. Due to its simple usage, WiFi has become an indispensable company in our digital life. However, it also makes the WiFi network will be easily targeted and attacked by cybercriminals.

WLAN vs. WiFi
Here we will compare the difference between WLAN and WiFi from the following aspects.
Definition
In short, WLAN is a general term for a local network that uses radio waves. You could consider WiFi as a special type of the WLAN network. It is short for wireless fidelity. They can allow devices to communicate within a limited range.
Standards
WLAN doesn’t require any certain standard. On the other hand, WiFi is based on the IEEE 802.11 standards to be more specific. They are a set of protocols that define how devices communicate through wireless technology.
IEEE 802.11 is designed for small spaces like your home, classroom, or small business. In addition, it is not limited to any frequency bands such as 2.4 GHz, 5 GHz, or 6 GHz.
Application
While connecting to the same wireless network, we can share files or data seamlessly between two or more devices. They are suitable for home or enterprise networking. Furthermore, WiFi supports VoWi-Fi and can also be used as a hotspot. You should also bear in mind that WiFi can only support IEEE 802.11-compatible devices.
Security
For WLAN networks, they usually depend on some specialized technology like Zigbee. On the other hand, some WiFi protocols like WPA2, and WPA3 can guard your connection. Apart from that, you have to enter the right passwords to connect to a WiFi network.
It can add an extra layer to your cyber security. To secure your WiFi network, you can regularly change your WiFi passwords. If you need any assistance, please read this blog: How to Change WiFi Password (Xfinity, Spectrum) on Any Device.
FAQs – Difference Between WLAN and WiFi
Q: Why is WiFi called WLAN?
WiFi is a kind of widely used WLAN network that follows the IEEE 802.11 standards. You can refer to it as a special form of the WLAN network. They all use wireless technology to ensure devices communicate smoothly with each other, instead of using wired cables.
Q: What is the disadvantage of WLAN?
WLAN network might encounter safety concerns, it could be easily attacked and accessed by unauthorized third parties. In addition, it is restricted to a certain range and the signals might be interfered with by walls, microwaves, and other furniture.
Q: Are WLAN and WiFi the same thing?
The answer is no. WiFi is a common type of WLAN network. Keep in mind that not every WLAN network can be called a WiFi.
