Hello, everyone!
Today, I would like to share a post on the WLAN benefits and drawbacks
In today's environment, an increasing number of networks operate without the usage of cables. Wireless LANs use high-frequency radio waves, infrared beams, or lasers to connect between workstations, file servers, and hubs. A wireless LAN is built by connecting many devices via a wireless network. The IEEE 802.11 standard governs WLAN.
It's easy to set up and use this network at home or anywhere else. Personal digital assistants, desktop computers, workstations and printers, mobile phones, and other devices are all connected through it.
In a WLAN, an access point (AP) is used to connect to the internet. The AP sends and receives frequency signals to and from the devices that are connected to it. In 1990, installing a WLAN was costly, therefore it was only utilized when a cable connection was unavailable. In the late 1990s, the cost of deploying WLAN fell due to the use of the IEEE 802.11 standard.
It has a two.4 GHz (802.11b) or five GHz (5 GHz) bandwidth (802.11 a). Clients are the devices that connect to a wireless network. The Wi-Fi Alliance is a non-profit organization dedicated to ensuring wireless network interoperability and standards. Wi-Fi is a term used to describe wireless networks.
WLAN provides a high data transfer rate. It functions like a star, with all nodes sending and receiving data through access points. It works better in both the home and the office. There are no additional cords required, especially in offices, and scheduling a meeting is a breeze. It's a knowledge transmission rate of 1-10 Mbps. In wireless LAN security, WEP or WPZ encryption is utilized. It can also use infrared technologies if necessary.
Benefits :
It's a reliable means of communication. Due to the lack of actual connections, WLAN is a diverse form of communication. WLAN depreciates a home's value. Workstations are more easily highlighted or removed. Because of its small service area, it has a high rate. You'll be able to move your workstation while maintaining connectivity as well.
The direction of connectivity is typically everywhere, i.e., you will connect devices in any direction unless they are within the range of the access point.
It's easy to set up, and you won't need any additional wires. When disasters strike, such as earthquakes and fires, WLANs come in handy. A wireless network can keep people linked in the case of a disaster. It is cost-effective due of the restricted access region.
The amount of power it requires is larger because it uses a transmitter; as a result, laptop battery life may be impacted.
Drawbacks :
WLAN usage necessitates the purchase of a license. There's simply a lot of area to hide. Government authorities can control and limit the flow of WLAN signals if necessary. Data transfer between connected devices and the internet will be affected as a result of this.
The data transfer rate slows as the number of connected devices increases. WLAN uses frequency, which might cause interference with other devices that use the same frequency. If there is rain or thunder, communication may be hampered.
Assailants may obtain access to the data being sent due to a lack of protection. When contrasted to fiber optics, signals may be affected by the environment. The environment is regularly harmed by WLAN radiation.
Wires and hubs are more expensive than WLAN access points. Signals from neighboring access points can be received by access points. When the standard changes, the network card and access point must be updated.
The LAN cable, which serves as the backbone of the WLAN, is still required. WLAN has a lower data transfer rate than a cable connection because it uses frequency. You have a good possibility of making a mistake. Unauthorized users may get access to non-secure communication.
