The new TTS-2000 from Piciorgros is a complete TETRA Site Survey Test Device to take measures of the RSSI Field Strength of the TETRA carrier as well as all reported neighbour cells. The data is stored as a -dBm value together with the location coordinates, bit error rate, antenna gain or attenuation value, and the RSSI values from all reported neighbour cells.
As graphical user interface, an Apple Mini iPad – that can be easily installed on the car windshield – is used for measuring, configuration as well as for parameter setting and for the device calibration.
During the measuring process that is done once per second (or distance depending), all relevant TETRA parameters like RSSI, LAC, Channel number and coordinates are shown on the iPad in big, well readable numbers.
Additional to the car power connector, the device can be operated for several hours with the internal rechargeable battery. And once the measuring process is completed, the csv-based data can be sent on a Wi-Fi or GSM network with just a fingertip to any e-mail address.
With the powerful Google Maps based application viewer “Cover Map” the user can view the data as graphical coverage overview on a PC or process it with his own Excel application. And he also can simulate certain conditions like switching off Base Stations or setting –dBm levels to check his network in extreme conditions.
The TTS-2000 is installed in a small Pelicase box of only about 24 /11 / 19 cm and can be used in a car or – due to its very light weight – is also ideal for hand carry measuring.
The Test Set is delivered together with an iPad Mini with installed software, the PC based application viewer Cover Map, magnetic antenna and a car changer cable.
