Advantages and Disadvantages of WLAN (Wireless Local Area Network)

Advantages of WLAN:-

  1. User mobility
  2. Voice and data services
  3. Scalable architecture
  4. Availability of all HiPath VoIP network services
  5. Access to central applications
  6. Handover between access points
  7. Robust model for industry
  8. Economical access points
  9. PlugandPlay
  10. architecture
  11. Robust controller
  12. Security on the level of fixed networks
  13. “Small Enterprise” option with own controller
  14. “Branch Office” option for small branches where remote controller is use

Disadvantages of WLAN:-

  1. As the number of computers using the network increases, the data transfer rate to each computer will decrease accordingly.
  2. As standards change, it may be necessary to replace wireless cards and/or access points.
  3. Lower wireless bandwidth means some applications such as video streaming will be more effective on a wired LAN.
  4. Security is more difficult to guarantee and requires configuration.
  5. Devices will only operate at a limited distance from an access point, with the distance determined by the standard used and buildings and other obstacles
  6. between the access point and the user.
  7. A wired LAN is most likely to be required to provide a backbone to the WLAN; a WLAN should be a supplement to a wired LAN and not a complete
  8. solution.
  9. Longterm
  10. cost benefits are harder to achieve in static environments that require few moves and changes.
