Wireless Site Surveys
What is a Wireless Site Survey?
A Wireless Site Survey, is the process of planning and designing a wireless network, to provide a wireless solution that will deliver the required wireless coverage, data rates, network capacity, roaming capability and quality of service (QoS).
Why Perform a Wireless Site Survey
In a word, wireless site surveys are necessary because radio wave propagation is difficult to predict, especially in non-open space environments.
It is virtually impossible to consider all the variables that might affect the health and performance of your WLAN. Changing conditions, even something as seemingly minor as a notebook equipped with a legacy 802.11g adapter that your new employee connected to the office wireless network, might seriously affect the WLAN performance.
In addition, considering the wide proliferation of wireless infrastructure, factors such as interference from nearby WLANs play a very important role. This is why regular site surveys that are conducted with a professional tool are important.
When to Perform a Wireless Site Survey
1. Pre-deployment surveys
At this stage, a site survey is necessary in order to verify that the network plan works well in a real-world environment. Placement of temporary access points and a quick survey of the resulting WLAN characteristics allow an engineer to fine-tune AP and antennae placement, determine the optimal number and types of APs and antennae, and avoid poor coverage zones
2. Post-deployment surveys
Once a WLAN has been deployed, a complete verification site survey is necessary to ensure that the WLAN performance and coverage meet the design requirements. At this stage, the Wi-Fi equipment placement is finalized and a site survey report should be generated so that the historical records can be accessed at any time in the future.
3. Regular, ongoing surveys
Maintaining high performance and coverage requires regular “check-up” surveys. New users, new equipment, site expansion, neighboring WLANs, and other factors can adversely affect your WLAN. It should be monitored on a regular basis.

Report Component Examples:
This visualization shows the signal strength map (also called the coverage map) measured in dBm. Signal strength is
one of the most important factors that influence WLAN performance, as in the areas with low signal, establishing a
reliable and high-throughput link between the AP and client devices is impossible.
Wireless Signal to Noise Ratio
This visualization shows the signal-to-noise ratio (SNR) measured in dB. SNR is a measure to quantify by how much
the signal level exceeds the noise level. Noise is generated by non-802.11 sources of radio waves (this includes
802.11 frames damaged during propagation). In low SNR zones, client devices may not be able to communicate with APs.
