Wireless Local Area Networks (WLANs) have become something we use every day without even realizing it. The technology is commonly found in homes, schools, campuses, offices, airports, libraries, and specific areas with limited coverage.
This wireless network provides multiple connections through access points to a wider internet network. What is the difference between WLAN and WiFi?
In this article, we will provide more information about WLAN, starting from its definition, advantages, disadvantages, and differences from WiFi.

What is WLAN?
A Wireless Local Area Network (WLAN) is a type of local network that uses radio transmission to connect devices in a limited geographical area, such as a home, school, or office. A computer network without the need for physical cables can be formed with a wireless network.
This local network is not limited to a single technology, but encompasses various communication standards and protocols that enable wireless connections between devices. The most commonly used technology for WLAN is Wi-Fi, which follows the IEEE 802.11 standard.
Many companies use this network technology because it is considered neater than wired networks. In addition, installation and maintenance costs are also considered to be cheaper.
The Advantages and Disadvantages of WLAN
Like other electronic devices, WLANs have several advantages that can be utilized and disadvantages that need to be considered. The advantages include unlimited flexibility, use of resource sharing, and cost-effectiveness.
On the other hand, the disadvantages include being vulnerable to hacking, slower transmission, and limited range. The following are the advantages and disadvantages of WLAN:
The Advantages of WLAN
Here are the advantages of Wireless Local Area Network:
Unlimited flexibility
One of the advantages of this wireless network is its flexibility. This network can connect from anywhere with wireless coverage, giving you freedom of movement. In addition, it supports a wide range of devices, from computers, smartphones, tablets, gaming systems, to IoT devices.
Greater mobility
WLAN offers greater mobility because it is not limited by a specific distance to access the network. As long as you are within the signal coverage area, you can use the network from anywhere. This increases your productivity without the hassle of cables.
Ease of resource sharing
Ease of resource sharing is another advantage of this wireless network. Users can share devices such as printers and files wirelessly. This makes your work easier and more efficient.
Easier installation and management
Another advantage of this wireless network is that it is easier to install and manage. Compared to wired networks, it requires less physical equipment. Installation is also easier and more practical without the need for complicated cabling.
More cost-effective
WLAN is more cost-effective in terms of initial installation and maintenance than wired networks. Network installation is easier because there is no need to install complicated cables. Network maintenance is also relatively cheaper because it uses fewer physical devices.
The Disadvantages of WLAN
Here are the disadvantages of Wireless Local Area Network:
Vulnerable to hacking
One of the disadvantages of this wireless network is its vulnerability to hacking. Compared to wired networks, wireless networks are more vulnerable to hacking. This is because signals can spread beyond the specified area. To make it more secure, extra security measures such as strong encryption are required.
Slower transmission
Another disadvantage of this wireless network is its slow transmission. Compared to wired networks, wireless networks have slower data transmission speeds. This can be caused by factors such as distance, interference, and the number of users sharing the same bandwidth.
Limited range
Limited range is another disadvantage of this wireless network . Its range is limited to the access point used. This can also occur due to the influence of walls or physical obstacles.
Susceptible to signal interference
Another disadvantage of this wireless network is that it is susceptible to signal interference. Wireless signals are vulnerable to interference from other electronic devices, such as microwaves or Bluetooth. In addition, adverse weather conditions, such as heavy rain and storms, can affect signal interference.
WLAN vs WiFi: What’s the Difference and Why It Matters?
Here is a brief overview of the differences between WLAN and WiFi.
| Aspects | WLAN | WiFi |
| Scope of terms | The concept of a wireless local area network | Implementation of WLAN following the IEEE 802.11 standard |
| Common usage | More commonly used in technical, academic, or network device documentation contexts | Popularly used by the public for wireless internet connections |
| Technology | Uses various radio technologies, such as WiFi, Bluetooth, and others | Specifically uses technology with the IEEE 802.11 standard |
| Standardization and certification | Does not always go through a commercial certification process | Must meet IEEE standards by the Wi-Fi Alliance to receive the “Wi-Fi Certified” label |
| Connectivity and infrastructure | Uses access points (infrastructure-based) or direct device-to-device connections (ad hoc) | Infrastructure-based and also ad hoc, depending on the device and its settings |
Understanding the difference between WLAN and WiFi is very important to avoid choosing the wrong network device, incorrect configuration requirements, and incorrect use of terminology when troubleshooting. In addition, for manufacturers and importers of network devices, this understanding is also related to regulations.
In every country, devices that use Wireless Local Area Network technology, including WiFi, must obtain Radio Frequency (RF) certification to be legally marketed.
This is information about WLAN, starting from its meaning, advantages, disadvantages, and differences from WiFi technology. Hopefully, this article can provide additional information for you in understanding this wireless network in general and its differences from WiFi.
In addition, you need to know that every product with a WLAN network that is marketed must undergo testing and RF certification from the authorities in charge of Wireless and Telecommunications Devices in your country.
