WiFi Site Survey

When considering the use of wireless networks, it is extremely difficult to predict the propagation of radio waves and detect the presence of interfering signals without the use of specialized test equipment.

Even if your installation includes omni-directional antennas, radio waves do not travel the same distance in all directions. Walls, doors, elevator shafts, people, and other obstacles offer varying degrees of attenuation, which cause the radio frequency (RF) radiation pattern to be irregular and unpredictable. As a result, one should have an RF site survey performed to understand fully the behavior of radio waves within a facility before installing any wireless devices.

What does a Site Survey give you?

The goal of an RF site survey is to gather enough information and data to determine the number and placement of access points that will provide optimal wireless network coverage. That usually means the support of a minimum data rate in a given area. An RF site survey will also detect the presence of radio interference coming from other sources that could degrade the performance of the wireless LAN.

The need and complexity of an RF site survey will vary depending on the size of the facility and the work that is to be accomplished. A site survey is a good idea for the use of any wireless device because without a survey, users could end up with inadequate coverage and suffer from low performance in some areas. The purchase of wireless equipment is no small expenditure, so it is best not to leave any portion of the project up to chance.

To ensure the accuracy of the final site survey report that WirelessBuilders delivers, only the latest and most sophisticated equipment is used. Handheld Spectrum Analyzers are used as a guiding tool to begin the survey. Afterwards, actual equipment is tested and retested, and then finally the report is generated with the consulting of the facility manager for current or future plans
