Welcome to TamoGraph Site Survey, a powerful and user-friendly
application for collecting and visualizing Wi-Fi data. Wireless
network deployment and maintenance requires the use of a
professional RF site survey tool that facilitates otherwise
time-consuming and very complex tasks, rates, etc. By using
TamoGraph, businesses can dramatically reduce the time and costs
involved in deploying and maintaining WLANs and improve network
performance and coverage.
Why to Perform a Site Survey
In a word, wireless site surveys are necessary because radio wave
propagation is difficult to predict, especially in non-open space
environments. Considering all the variables that might affect the
health and performance of your WLAN is virtually impossible.
Changing conditions, even something as seemingly minor as a laptop
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 conducted
with a professional tool are essential.
When to Perform a Site Survey
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 (APs) 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. Using TamoGraph,
you can also perform a simulation in a virtual environment prior to
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.
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.
There are three types of surveys that you can conduct with
the application collects the most comprehensive data on the RF
environment: information on access points and their
characteristics, signal strength, noise level, interference, etc.
This is the default and most important survey type that we
recommend to conduct in every case. It is called passive because
during this type of survey, the application passively listens for
packets and does not attempt to connect to WLANs. However, to
provide more insight into the real-world performance of your WLAN,
TamoGraph can also perform
during which your Wi-Fi adapter connects to the wireless network(s)
of your choice to measure actual throughput rates and a few other
metrics. Unlike passive and active surveys,
are not performed on-site. Predictive surveys are a computer
simulation in which Wi-Fi characteristics are predicted for the
virtual environment model created by the user. The process of
creating and adjusting the virtual environment, selection and
placement of simulated APs, and analyzing the resulting WLAN is
commonly referred to as “RF planning.” Please refer to the
Understanding Survey Types: Passive, Active, and
chapter for more information on this topic.
