WLAN: What Is Wireless LAN In Computer Networks?

Hello Friends, In this blog post(What Is Wireless LAN In Computer Network) I am going to let you know about wireless LAN. A wireless LAN makes use of a wireless transmission medium.

In this blog post(What Is Wireless LAN In Computer Network), we are going to explore Can wireless LAN connect to WiFi? What is the difference between WiFi and wireless LAN? What is LAN WiFi? Is wireless LAN the same as Bluetooth?

Can wireless LAN connect to WiFi?/What Is Wireless LAN In Computer Networks?

Wireless LAN is an architecture or arrangement where all the devices communicate with each other without any wire.|What Is Wireless LAN In Computer Network|

As in the normal LAN or wired LAN, the device is connected with the LAN cable and then they communicate with each other device. In WLAN the devices communicate wirelessly via a WIFI network.|What Is Wireless LAN In Computer Network|

What is the difference between WiFi and wireless LAN?

Wireless LAN is a specific area or a local area network where devices can communicate with each other device wirelessly via wifi or with a hotspot network.

Whereas WIFI is a wireless network that can be used by several WLANs or any other network type.

What is LAN WiFi?

A LAN is a local area network that can have wired and wirelessly connected devices.

This is a personal network like in college and small company offices.

Is wireless LAN the same as Bluetooth?

The working of both are quite similar as both are used to share data and information by connecting with other devices.

But Bluetooth is a younger technology and is not much effective in terms of speed as compared to wireless LAN which is very fast in processing and transmitting data from one device to another device.

Wireless LAN is a fast-growing market introducing the flexibility of wireless access into the office, home, or production environments.

Wireless LAN is typically restricted in its diameter to buildings, a campus single room, etc.

Wireless LAN is operated by individuals, not by large-scale providers.

The main goal of wireless LAN is to replace office cabling and additionally introduce higher flexibility for ad-hoc communication.

Until relatively recently, wireless LAN was a little used. The reasons for this included high prices, low data rates, occupational safety concerns, and licensing requirements.

As these problems have been addressed, the popularity of wireless LAN has grown rapidly.

A wireless LAN must satisfy some type of requirements typical of any LAN, including high capacity, ability to cover a short distance, full connectivity among attached stations, and broadcast capability.

Furthermore, there are several requirements specific to the wireless LAN environment.

The following are the main requirements for a wireless LAN.


To maximum capacity, the medium access control protocol should make as efficient use as possible of the wireless medium.

Many nodes:

Wireless LAN may be required to support hundreds of nodes across multiple cells.

Connection to backbone LAN:

Generally, interconnection with stations on a wired backbone LAN is needed.

This is easily accomplished for infrastructure wireless LAN through the use of control modules that connect to both types of LAN.

There may also require to be accommodation for mobile users and ad-hoc wireless networks.

Service Area:

For a wireless LAN, a typical coverage area has a diameter of 100 to 300 m.

Battery power consumption:

Mobile workers use battery-powered workstations that require long battery life when used with wireless adapters.

This suggests that a MAC protocol that needs mobile nodes to monitor access points constantly or engage in frequent handshakes with a base station is not suitable.

Typical wireless LAN implementation has features to decrease power consumption while not using the network like a sleep mode.

Transmission robustness and security:

Unless appropriately designed, a wireless LAN may be interference-prone and easily eavesdropped on.

The design of a wireless LAN must allow reliable transmission even in noisy environments and should provide some level of security from eavesdropping.

Collected network operation:

When wireless LAN becomes more popular, it is quite likely for two or more wireless LANs to operate in the same area or in some areas where interference between the LANs is possible.

This type of interference may thwart the normal operation of a MAC algorithm and may permit unauthorized access to a particular LAN.

License-Free Operation:

Users would prefer to buy and operate wireless LAN products without having to secure a license for the frequency band employed by the LAN.


In a wireless LAN, the MAC protocol used should enable mobile stations to move from one cell to another.

Dynamic Configuration:

MAC addressing and network management aspects of the LAN should allow dynamic and automated addition, deletion, and relocation and end systems without disruption to other users.
