Which events are possible in wireless LAN?
Explanation: Collision detection is not possible in wireless LAN with no extensions. Collision detection techniques for multiple access like CSMA/CD are used to detect collisions in Wireless LANs.
How does a wireless LAN work?
In short, a wireless local area network (WLAN) provides access to the Internet without the need for cables or other wires hooking directly into your computer. Instead, an access point (AP) connects other wireless devices to your local area network (LAN).
What is the access point in a wireless LAN?
An access point is a device that creates a wireless local area network, or WLAN, usually in an office or large building. An access point connects to a wired router, switch, or hub via an Ethernet cable, and projects a Wi-Fi signal to a designated area.
What are the applications of WLAN?
Uses of Wlan
- Healthcare. Doctors and nurses equipped with laptops or PDAs have faster access to patient data.
- Conducting everyday business.
- Network managers in older buildings.
- Network managers in dynamic environments.
What are the features of wireless LAN?
17 Features Every Fast, Secure WiFi Network Should Have
- High Capacity Load Balancing.
- Scalability.
- Network Management System.
- Role Based Access Control.
- Indoor as well as Outdoor coverage options.
- The Ability to Measure Performance.
- Network Access Control.
- Ability to communicate with both 2.4 GHz devices and 5 GHz devices.
What is wireless local area network with diagram?
Stands for “Wireless Local Area Network.” A WLAN, or wireless LAN, is a network that allows devices to connect and communicate wirelessly. Unlike a traditional wired LAN, in which devices communicate over Ethernet cables, devices on a WLAN communicate via Wi-Fi.
What is the access method used by wireless LAN?
Carrier Sense Multiple Access with Collision Avoidance
IEEE 802.11 wireless LANs use a media access control protocol called Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA). While the name is similar to Ethernet’s Carrier Sense Multiple Access with Collision Detection (CSMA/CD), the operating concept is totally different.
What is the purpose of a wireless network diagram?
A wireless network diagram is a specialized type of computer network diagrams. Wireless Network diagrams are used to develop, operate and maintain the WLAN systems. Making a Wireless Network diagram involves many different elements that can be managed using ConceptDraw DIAGRAM.
What are the architectures of a wireless network?
There are two architectures available, namely standalone and centrally coordinated wireless network. By using ad hoc mode, all devices in the wireless network are directly communicating with each other in peer to peer communication mode. No access point (routers/switches) is required for communication between devices.
What are the characteristics of an infrastructure mode wireless network?
An infrastructure mode wireless network has the characteristics as below: The wireless centralized controller coordinates the activity of access point. The controller is able to monitor and control the wireless network by automatically reconfiguring the access point parameters in order to maintain the health of the network.
Which is the central device in the WLAN architecture?
Access Points Access points (APs), normally wireless routers, are base stations for the wireless network. APs transmit and receive radio frequencies for wireless enabled devices to communicate with. It uses as Central Device in WLAN architecture. 9. Access Point 10.
