What are the components of WLAN?

Wireless LAN Components

• User Devices. Users of wireless LANs operate a multitude of devices, such as PCs, laptops, and PDAs.
• Radio NICs. A major part of a wireless LAN includes a radio NIC that operates within the computer device and provides wireless connectivity.
• Access Points.
• Routers.
• Repeaters.
• Antennae.

  What are the four components of WLAN?

  Basic components of WLAN are typically: wireless access points. network interface cards (NICs) or client adaptors.

  What type of authentication does an access point use by default?

  By default, SSIDs on Cisco Meraki access points that are configured as WPA2 utilize a combination of both TKIP and AES encryption. WPA2 Enterprise utilizes authentication on a user level, using the 802.1x standard, along with the features of WPA2 such as AES.

  What are two authentication methods that an access point could use?

  Note: Although an access point can use Open Authentication with EAP method to authenticate a wireless client device, an access point cannot use EAP to authenticate another access point. In other words, access points must authenticate each other using either open, shared, or Network EAP authentication methods.

  What is WLAN example?

  WLAN Devices Wireless LANs can contain many types of devices, including: Mobile phones. Laptop and tablet computers. Internet audio systems.

  What are the two basic types of WLAN topologies?

  The 802.11 standard identifies two main wireless topology modes: infrastructure mode and Independent Basic Service Set (IBSS). IBSS is also knows as ad hoc mode. With the ubiquity of wireless networks, mesh topologies are now common.

  What is the best authentication method for wireless?

  WPA stands for WiFi Protected Access. This authentication method uses different encryption algorithms to encrypt the transport. Therefore, this type of network cannot be forged easily, unlike open networks, and users get privacy. Today, WPA2 is probably the most commonly used method to secure WiFi networks.

  What is the difference between using open authentication and pre shared keys?

  What is the difference between using open authentication and pre-shared keys? Pre-shared keys require a MAC address programmed into the access point. Open authentication does not require this programming.

  What type of authentication can be used for network access?

  Extensible Authentication Protocol (EAP) This protocol supports many types of authentication, from one-time passwords to smart cards. When used for wireless communications, EAP is the highest level of security as it allows a given access point and remote device to perform mutual authentication with built-in encryption.

  Where is WLAN used?

  A wireless LAN (WLAN) is a wireless computer network that links two or more devices using wireless communication to form a local area network (LAN) within a limited area such as a home, school, computer laboratory, campus, or office building.

  What is WLAN and its types?

  Wireless LANs (WLANs) are wireless computer networks that use high-frequency radio waves instead of cables for connecting the devices within a limited area forming LAN (Local Area Network). Most WLANs are based upon the standard IEEE 802.11 standard or WiFi.

  What are the two main WLAN architectures?

  WLANs are described by three broad categories of architectures: autonomous, centralized (controller-based), and cooperative (controller-less).
