What is a Wireless LAN (WLAN)? A Wireless LAN (WLAN or W-LAN) is a “Local Area Network” for wireless users, whether in a residence, dedicated business setting or in the nature of a mobile user off-premises. The connection is made through a wireless (radio Wi-Fi) connection. A Wireless LAN’s network links two or more devices using a wireless, a multi-channel delivery method within designated, finite areas such as a café, office building, home, school or any business that makes available to its employees or guests the availability or privilege of connecting to the internet.
Security is top-of-mind, with speed the most requested priority. Wi-Fi networks are usually deployed in an infrastructure node, where a base station will act as a hub or wireless access point hub. Sometimes called a “Hotspot.” Nodes then communicate through the hub, which usually has a wired or fiber network connection. There may be permanent wireless connections to other nodes and a hard-wired redundant network used as a backup instead of the original primary system. Networks may offer multiple access points, within the same security SSID system. The client software would try to choose the best signal through the strongest access point. PeerSpot users choose Wireless LANs based on criteria such as ease of system management, the best available technical features, monitoring systems, open platforms, user support/vendor updates and reasonable cost. It is essential to detect and minimize any signal strength interference and implement adequate coverage. The IT professional will assess how many Wi-Fi units are needed, where they are placed and the quality and strength of roaming so client devices seamlessly navigate. Bandwidth and scalability need to be balanced with the thought of future needs, and one must take into account the speed of evolving technology to mitigate investments.
Some are of the opinion that Wi-Fi itself is ubiquitous and mainstream, yet becoming problematic because of access security, vital equipment compatibility and bandwidth and load balancing. The software needs to be updateable and brand reputation and longevity becomes an issue when forecasting ahead 5 years+.
Wireless LANs must secure networks from non-credentialed users, yet allow authorized and guest users access. PeerSpot IT professionals are aware that the best available computers and peripheral equipment investments up front are the prudent choice to anticipate IP telephony, growth of bandwidth, video- conferencing and multi-media use that can on some levels grow exponentially. Some users will find large data files presently work better through a legacy Ethernet connection, but this may quickly change and the FCC is now a factor in available resources.
A wireless LAN (WLAN) is a type of wireless computer network that forms a local area network (LAN) by linking devices using wireless communication. These networks use radio transmissions instead of cable or wired connections. WLANs often use an access point (AP) to connect to the public internet.
Wireless connections are the most popular form of connecting to the internet. Wireless networks are inexpensive, easy to set up, and unobtrusive.
A WLAN (wireless local area network) transmits data using radio waves. The network gives access to the internet without the need for connecting cables. Instead, a WLAN uses a device called an access point (AP) to connect wireless devices to the local area network (LAN).
High-frequency radio waves transmit packets from the LAN to your computer. The data packets going through the WLAN have instructions and addresses assigned to endpoints so that the network can route the packets to the designated locations. Wi-Fi networks are a type of WLAN that conforms to a specific standard.
Here’s how a WLAN sends information:
Similarly, when the router receives information from the internet, it translates it into a radio signal and sends it to the computer’s wireless adapter.
Wi-Fi is a type of Wireless LAN (WLAN). Both technologies connect devices without the need for Ethernet cables or dial-up modems.
Wi-Fi (wireless fidelity) is a type of wireless network that uses a wireless router to connect different devices. Wi-Fi allows desktops, mobile devices, and other types of equipment, like printers, scanners, sensors, and cameras, to connect to the internet.
Wireless routers are commonly found in homes and offices, connecting you to your internet provider’s network. Mobile devices can share their wireless connections with other devices when the phone’s mobile hotspot is enabled.
A wireless local area network (WLAN) can have two different types of configurations:
Infrastructure |
In this model, the endpoints connect and communicate through a base station, which often also provides internet access. The infrastructure consists of a few basic parts: the wireless router that acts as a base station, endpoint devices, desktops, and mobile devices. Usually, the router also connects the devices to the internet. |
Ad Hoc |
This model doesn’t use a base station to connect endpoints. This type of WLAN only requires the endpoints (such as mobile devices) to have built-in radio transmission. A user can adjust the network settings to allow the ad hoc connection, becoming visible to others, who can then connect to him. |
In terms of connectivity, there are three types of WLAN deployments:
Centralized
This is the most common type of wireless network system, typically deployed in places where buildings are close to each other. This type of deployment enables advanced wireless functionality. The network controllers are usually installed at a central location.
Converged
Converged deployment combines wired and wireless connections on one network device - the access switch. This device works as a wireless controller and as a network switch.
Cloud-Based
Some wireless networks use the cloud to manage on-premises devices at different locations. This keeps the controller in the cloud, enabling management, monitoring, and updating the WLAN.
What are the benefits of wireless local area networks (LANs) over wired LANs?
A wireless LAN connects devices wirelessly, using an access point (AP) that connects the devices to the internet, sending and receiving information packets through radio frequencies. This wireless connection provides the same service as wired LAN but without the cost and the hassle of installing massive cable routes to connect users with the network.
