Chetnet Wireless SurveysWireless Surveys that will improve your wireless network: predictive model WiFi survey, a passive onsite WiFi survey, an active onsite WiFi Survey and the fault-finding WiFi survey. Each type of survey differs according to the site or your specific requirements
Predictive wireless surveys use computer-based software programs to model the facility and RF environment and relies on high-quality building plans
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.
Passive wireless surveys is when the surveying device is not connected to any WiFi network and is only listening to the WiFi environment
Passive Site Surveys are most commonly used in buildings that already have a wireless infrastructure. Collecting the most comprehensive information from important WLAN characteristics and metrics, passive site surveys measure the signal strength and noise level of any active access points. interference.
Active wireless surveys are when a surveying device is connected to the WiFi network and records signal measurements based on the performance of the connection
Active surveys are performed with the survey client associated with the AP”s used throughout the survey. When a client is associated, it performs all the tasks a typical 802.11 client performs, which includes rate shifting data rates as the RF condition changes and performs retransmissions. Active surveys are commonly used for new WLAN deployments because they provide the most details on which to base a design.

A wireless site survey will identify signal strength at all points of your building, creating the foundations for a solid radio enhancement system. It offers information about where to put access points to get around poor signal and interference. Guessing how many APs you need and where to place them can result in poor signals and dead spots if you don’t install enough. This can hurt your bottom line. Plus, if you install too many AP’s, you’re wasting money at no real benefit.
When deploying a wireless network WiFi access points (APs) are often placed at random places. In small deployments, the ad-hoc approach is not a problem but with medium, to large deployments a wireless site survey is advised and often needed.
A wireless survey helps to determine where to place WiFi APs to avoid interference and avoid overlap coverage from other APs. In practice, many network managers just randomly place WiFi APs and simply install extra WiFi APs when extra coverage is needed or when they get complaints about bad WiFi access.
In an ad-hoc wireless network, the network manager has no idea what kind of interference exist and how the site’s radio signal profile changes. By getting a wireless site survey, it will help determine if there are co-channel interferences and how much, where external radio interferences are causing problems and how to minimize the number of WiFi APs needed and where to optimally place the WiFI APs for best coverage.
It is important to understand that a wireless site survey is a snapshot of the site’s radio signal profile at that time. As the site changes with the new addition of people, cubicles, furniture, and electronic equipment, its radio signal profile changes and may require a new site survey.
