Benchmarking data delivery over TETRA versus commercial networks

Posted Nov 2011

Evolved Intelligence, the mobile data applications company, has launched a new method of benchmarking the delivered data performance of TETRA networks versus commercial alternatives such as GPRS and 3G. The approach uses the company’s Sensustech technology which deploys automated probes into vehicles.

Says Evolved Intelligence’s CTO, Nick Jones: “For the users of mobile data, the choice of carrier network can be a tricky one. Of course, for truly mission critical applications, TETRA is the natural choice as commercial systems may become clogged, suppressed or even turned off during a major incident. However for other, less mission critical applications, the choice may not be quite so straightforward.”

Sensustech uses a combination of GPRS and TETRA enabled automated probes which communicate with a central server sending and receiving test messages. These probes, called PAMs, are fitted into vehicles which are moving around the geography of the area of interest. In practice these are often the vehicles of the interested user.

Says Evolved Intelligence’s Marketing Director, Robin Burton: “These practical field tests show very interesting results. Whilst commercial networks, on the face of it, offer apparently higher data rates, in many practical scenarios such as high speed motorway driving, rural areas and in crowded areas such as traffic accidents or football matches, they can offer very poor service. A Sensustech survey allows mobile date users to fully understand the options available to them.”

Evolved Intelligence also offers a data applications delivery platform designed to deliver efficient data delivery over TETRA and other bearer networks through the use of specially designed protocols. The company believes that, in many typical applications such as enquiries on a passport data base, TETRA can deliver performance which is as good, if not better, than that actually on offer from commercial networks.
