1 Overview
1.1 What is Aries?
Aries is an autonomous TETRA network monitoring tool that provides real-time performance statistics. It
consists of many small probes that connect to the back of existing TETRA radios as well as software that
runs on a web server. As the vehicles with the TETRA radios and probes travel across the network, data is
sent from the probes back to a central web server so that a picture of network performance builds up.
Results may be viewed in real-time as maps, graphs, tables and warnings using a secure password-
protected web site available on any Internet connected PC using a standard browser.
Aries provides first-line TETRA network monitoring of faults and problems with the facility to send warning
SMS to service engineers when key metrics are exceeded. Problems can then be investigated further with
the detailed technical data and powerful analysis functionality.
Aries provides a picture of the network performance that is not available from the standard TETRA network
call logging as it takes into account all of the failed calls and poor coverage areas and it provides a true
and independent measure of grade-of-service as perceived by the user.
Aries monitoring probes are ideal for fitting in any vehicle that regularly travels across the TETRA service
area such as public transport - once installed they can be forgotten about.
Aries key features:
• Autonomous monitoring of TETRA network performance
• Sends SMS to service engineers when network faults detected
• All results presented in real-time on secure web pages accessible from any browser
• Built-in powerful analysis functions for investigation of network faults
• Low-cost, small, robust probes can be fitted in a any vehicle
