Test Drive the SNYPER-LTE Graphyte for Free:
Siretta Cellular Signal Strength Data Logger




This presentation will explain in simple terms how the cellular networks operate in respect of a cellular device network registration process, aimed at engineers with no prior knowledge of how a cellular network operates. Using this knowledge, the reasons for a site survey are discussed and the SNYPER Graphyte cellular survey tool is introduced. Finally, the survey reports obtained are interpreted and used to give advice on how to select and place an antenna for best network performance.


What you'll learn:

•        The reason to do a cellular survey

•        Basics of how a cellular device works out which base station to register to

•        Using the SNYPER-Graphyte to conduct cellular surveys

•        Understanding survey results

The SNYPER-LTE Graphyte (USA) is a high performance, multi-language network signal analyser and cellular signal logger, dedicated to surveying and logging the 4G/LTE (USA), 3G/UMTS & 2G/GSM North American networks.


The unit can be left to conduct sequential surveys in a fixed location and automatically saving them. Four types of survey can be performed: a “FULL” survey (4G, 3G and 2G combined), 4G/LTE only, 3G/UMTS only & 2G/GSM only.


SNYPER-LTE Graphyte (USA) can save multiple surveys each with different logging options and all survey results can be downloaded to a PC and displayed in a HTML graphical format to clearly show the logged detail over the survey session. This can identify unreliable base-stations & intermittent cellular service which is not possible with spot surveys. The full breakdown for the HTML summary graphs are displayed in corresponding CSV files (Summary and full detail files).


The SNYPER-LTE Graphyte (USA) also incorporates Siretta’s leading liveSCAN feature, which allows you to select a base-station signal immediately after a survey, conduct a liveSCAN logging session which can later be analysed in a CSV logged recording. The SNYPER-LTE Graphyte (USA) is an invaluable tool for understanding local network performance over hours, days and weeks to assist in the selection of reliable mobile network operators before cellular installations.

  • Enhanced cellular surveying & sequential logging of new and existing installations on 4G, 3G and 2G networks
  • User selectable survey logging options to determine most suitable & reliable mobile operator
  • Evaluate “preferred” MNO’s performance over time
  • Determines “hotspots” & assist with antenna alignment, through Siretta’s liveSCAN feature
  • Results are reported in CSV & graphical HTML format
  • Save over 100 logged surveys with multiple liveSCAN logs
