Planning for a wireless network?

Discover RF Coverage Areas/ Coverage Holes

Identify sources of RF Interference (internal – microwave owens, cordless phones, satellite dishes, etc; external – neighboring access points, etc)

Determine the Quantity & Optimum locations for placement of Wireless

Predictive Survey

A predictive site survey is a virtual survey of your site or facility that uses pertinent information about the site to plan the wireless network. The value to our clients is that the cost is extremely less than traditional onsite surveys and the time to complete the survey is reduced significantly.

Pre-deployment Survey

A pre-deployment site survey, often-called an “AP-on-a-stick” survey, is performed before a WLAN network deployment. This type of survey determines the RF signal propagation characteristics of the environment. Measuring and recording the RF behavior in a facility results in a better WLAN design, one uniquely tailored to the physical properties of the environment. You can also use it to verify and adjust a preliminary Wi-Fi network design and to minimize changes to purchase orders once you have procured and installed your WLAN equipment. Spectrum analysis is an integral part of a pre-deployment site survey. Use it to identify and remediate sources of RF interference that could cause WLAN performance issues.

Post-deployment survey

A post-deployment site survey is performed after the WLAN equipment has been installed and configured. This type of site survey reflects the RF signal propagation characteristics of the deployed WLAN. At this point, you have already installed the network equipment, and the focus of the survey is to validate that the installation matches the final network design.

Why perform a wireless (RF) site survey?

With wireless systems, it’s very difficult to predict the propagation of radio waves and detect the presence of interfering signals without the use of test equipment. Even if the system implements omni-directional antennas, radio waves don’t really travel the same distance in all directions. Instead walls, doors, elevator shafts, people, and other obstacles offer varying degrees of attenuation, causing the RF (radio frequency) radiation pattern to be irregular and unpredictable. As a result, it’s absolutely necessary to perform a wireless site survey (also called RF site survey) to fully understand the behavior of radio waves within the operating environment before installing access points.
