Planning for a Wireless network is not as simple as planning for a Wired network. A site survey is the first step in the deployment of a Wireless network and is also the most critical step to ensure desired results. A site survey is a task-by-task process of planning and designing a Wireless network, to provide a Wireless solution that will deliver required Wireless coverage, network capacity, roaming capabilities and quality service.
A Wireless network is comprised of Wireless Access Points, Wireless clients, Wireless Controller and the passive and active network components that connect them to the LAN. In a Wireless network, many issues can arise which may prevent the radio frequency signal from reaching all areas of a facility. A site survey will help you identify the regions where these issues occur, and then you will be able to address these appropriately. The site survey will also assist in defining the outline of radio frequency in a particular area, which helps determine your total coverage area, so you can be certain that all areas that are needed are being attended to. By performing a Wireless site survey you will discover areas where multipath distortion can occur, as well as areas where radio frequency interference is high and you will then be able to find solutions to eliminate such issues. Only by understanding your total coverage area and where coverage is will you be able to choose the number of Wireless devices your organization needs to meet your business requirements.
By performing a proper site survey you will be providing your organization with detailed information addressing coverage, sources of interference, equipment location, power consideration, and writing requirements. The documentation you receive following a site survey will serve as a guide for future network design and for the installation and verification of the Wireless communication infrastructure.
