Designing a Wireless LAN

Wireless LANs are made up of several key components that provide the wireless solution; there are many varieties of wireless accessories, so it’s important to implement the right ones for your business.   Depending on location and traffic, certain components may need to be added and others may not.  You need to determine the requirements of the wireless LAN before implementation.  Factors you need to consider before you start include:

  • Coverage– you must determine the amount of coverage desired, how big or small is the area that users will operate the wireless devices in?
  • Mobility– what kind of mobility requirements will users require? How much movement will there be throughout the coverage area?
  • Transmission Rate– What kind of applications will you be using and what type of bandwidth will they require?
  • Users– How many devices will be utilizing the wireless LAN? Also consider expansion.
  • Devices– What types of wireless devices will you be using, laptops, mobile computers, etc.
  • Security– What level of security is desired?

Implementing a WLAN can be a large undertaking and you want to be sure you get the design right.  It’s important to ensure sufficient capacity for users and applications, but you’ve also got to think about coverage and bandwidth. 

Some of the standard components of a wireless LAN solution include access points, PC cards, wireless switches or controllers and mobile devices.  I’ll take a closer look at each component in my next post later this afternoon, Wireless LAN Requirements.
