Wireless Calculator – Explanation

The Wireless Calculator tool for wireless access points asks a number of questions that will help with the estimation of the number of wireless access points required for your building. The key questions are:

  • Building length
  • Building width
  • The average number of rooms per floor in the building
  • Number of floors
  • Type of interior walls
  • Use of the network: what is it for?

In addition, there are extra questions such as what is the height of the wireless access points. The standard value for this is 245 centimeters, the height of an average ceiling in office and residential environments.

The frequency band can also be entered. The default is 2.4 GHz which provides a wider coverage but suffers from the fact that there is a greater chance of interference. Not all equipment supports 5 GHz.

The setting of the output power for the wireless access point requires some expertise. The default setting is 25 milliwatts because many receivers have low levels of output power. A (too) high setting can result in poor connections after installation. This applies especially to PDAs and other battery-powered wireless equipment (including many laptops).
