Tamograph

Powerful wireless site survey tool

  • Passive, active, and surveys (a.k.a RF modeling)
  • Comprehensive WLAN analysis with visualsation.
  • Full support of 802.11ax, 802.11a, 802.11b, 802.11g, 802.11n, 802.11ac networks
  • Detailed information about every access point.
  • Dozens of antenna patterns allow you to model APs by major WLAN vendors.
  • Detailed reports containing all survey information and visualisations
  • Support for both Windows and Mac OS

Tamograph Pro

Predictive Wi-Fi Surveys

TamoGraph can be used for planning WLANs that have not been deployed yet. This type of survey is called "predictive" or "virtual," because 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 analysis of the resulting WLAN is commonly referred to as "RF planning. To create a virtual model of the environment, the user needs to "tell" the application about the position, size, and type of the physical objects that affect radio wave propagation.

Passive Wi-Fi Surveys

Passive surveys are the most comprehensive , providing the most important WLAN characteristics and metrics. Tamograph passively listens for packets from the WLAn/s under test and does not attempt to connect to any Access Points.

During a possive survey the following metrics are collected and displayed.

  • Signal Level
  • Signal-to-Noise Ratio
  • Signal-to-Interference Ratio
  • AP Coverage Areas
  • Number of APs
  • Expected PHY Rate
  • Frame Format
  • Channel Bandwidth Requirements

Active Wi-Fi Surveys

Active Wi-Fi surveys provide you with measurements of of real-world performance characteristics of your WLAN. Tamograph connects to your Wi-Fi adapter and to the wireless network(s) that you choose to measure actual throughput rates and other metrics.

Using an active survey the following metrics are collected and displayed.

  • Actual PHY Rate
  • TCP Upstream Rate *
  • TCP Downstream Rate *
  • UDP Upstream Rate *
  • UDP Downstream Rate *
  • UDP Upstream Loss *
  • UDP Downstream Loss *
  • Round-trip Time
  • Associated AP Requirements

* When using advanced mode with a throughput server utility connection.

Spectrum Analysis in TamoGraph

TamoGraph can perform spectrum analysis simultaneously with passive surveys by interfacing with the MetaGeek Wi-Spy DBx, a USB-based spectrum analyer. Spectrum analysis involves the use of special RF equipment designed to listen to and analyze the frequency bands utilized by Wi-Fi devices. When Wi-Spy is plugged in, a live spectrum picture is displayed on the central pane of the main TamoGraph window.

TamoGraph is a powerful and user-friendly wireless site survey software tool for collecting, visualising, and analysing 802.11 a/b/g/n/ac/ax 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, such as ongoing analysis and reporting of signal strength, noise and interference, channel allocation, data rates.

FAQS

Q:
What operating systems can Tamograph be run on.
A:

Tanograph can be run on both Windows and Mac operating systems

Q:
Can I install Tamograph on multiple machines.
A:

No, Tamograph is a single license software meaning you can only install it on one machine at a time.

Q:
Do I need a compatible Wi-Fi card to perform an active survey on Tamograph
A:

No, you can use pretty much any modern Wi-Fi adapter. However, active surveys give you only a small part of the WLAN picture. To get comprehensive information, passive surveys are mandatory. A compatible adapter is required for passive surveys.

Q:
Do I need a special adapter if I want to include spectrum (interference) information in my Site Surveys
A:

Yes, you will need to purchase a Metageek Wi-Spy DBX from us, or purchase one of our Tamograph packages that includes both the Tamograph software and Wi-Spy DBX.
