TETRA Active - Data Sheet

A TETRA Active system consists of a central server and a number of remotely connected mobile or static probes. Probes connect to a TETRA terminal with call, network and terminal event information being transferred back to the TETRA Active server for processing. The following diagram illustrates the key components and their function.

External connections;

− 10-32v d.c − 2 x FAKRA connectors for GPS & GPRS antenna − 1 x RS232 serial − 1 x USB device interface − 1x 10/100Mbs Ethernet

On-board storage for approx 8 hours of local data capture.

SD memory card slot for data storage expansion.

SIM card holder – requires separate GPRS data service. (customer responsibility)

Operating Temperature: 00 to +700; (optional; -400 to +850)

Transfer of data from TETRA Active Probes via Ethernet or GPRS employing 128 bit encryption.

TETRA Active Probe - (Portable)

Windows™ or Android Smartphone device (check for compatibility)

Transfer of data to/from TETRA terminal via Bluetooth

Transfer of data from TETRA Active Probes via Smartphone device

TETRA Active Server

Typical specification: (exact specification depends on number of probes deployed)

Intel Xeon Quad core processor, >16GB RAM, 2TB HDD (Raid 5)

MS SQL 2008 and MS Windows 7

Hardware can be supplied by Syntech or provided by customer;

In-built mapping capability uses MapServer & GDAL/OGR. Interfacing with existing mapping servers is also possible (contact Syntech for details).

1 Number of probes will determine the requirements for the TETRA Active server.

TETRA Active - User Interface

The TETRA Active console provides a management and configuration interface for the system. The console provides a real-time, visual summary for each connected probe including:

− Recent service affecting events show how many and when they occurred over the preceding 24 hour period.

− Current RSSI levels

− Location of each probe displayed on a map (zoom in/out, show layer details, including base sites etc).

Dashboard

Selecting any probe from the summary view opens a new window where full details of the selected probe are provided. A multi functional dial provides a real-time display of serving and neighbour cell information. The accompanying map display shows the selected probe’s position and status. Parameters include:

− Serving cell information; LAC, Frequency, RSSI, C1, Min Rx Access level

− Neighbour cell information; LAC, Frequency, RSSI, C2, Min Rx Access level

− Terminal handover status indicator lights; cell usable, improvable relinquishable

− Cell reselect thresholds and indication that handover conditions are met.

− All events are displayed on the accompanying map view and in the event window



TETRA Active - Reports

TETRA Active provides the following standard set of reports from its SQL database. Report data can be viewed, printed saved or exported as .doc, .csv, xml, tiff, .pdf formats.

Test Summary Shows a summary of each test including key

performance metrics for calls, service levels, cell acquisition & reselections and SAE

Call Report Call setup times, number of calls, duration,

success etc Duplicate Frequency Report Identifies frequencies that are duplicated for

two or more sites within a neighbour cell list Frequency Reports Reports the frequencies identified for each

site and identifies any service affecting events.

Neighbour mismatch Report Compares the expected neighbour cell list

with the broadcast neighbour cell list and highlights any differences

RSSI Report Reports the quantity and distribution of

collected RSSI values for each site Site Criticality Report Reports for each site the percentage of RSSI

samples that fall within a specified range e.g. critical, marginal, acceptable

Service levels Report Shows the service level,; according to RSSI

and time on each site recorded for each probe.

Service Affecting Events Report Identifies and counts any events classed as

service affecting together with details of site, RSSI, time etc.



GIS Mapping

TETRA Active can create Google Earth™ KML files for each test period. Resultant maps provide selectable data layers for the display of;

− Sites

− RSSI values

− Service Affecting Events

− Cell Re-selection Events

− Service Levels according to sites

− Affiliation map

− Site Criticality map

− Call details

TETRA Active’s in-built mapping capability uses the Open source MapServer & GDAL/OGR standards. Interfacing with customer’s existing mapping servers is also possible (contact Syntech for details).



Options

Accessories

GPS and GPRS antennae

Enclosures for Static probes; e.g. IP55, desk/wall mount, transportable etc.

Additional Capabilities

TETRA Active can be enhanced to provide additional performance measuring capabilities for TETRA voice and data services (Individual calls, SDS, status, Packet data, Emergency, Broadcast) including;

• Success rates for voice and data calls

• Speech quality (P.862.1 PESQ or P.863.1 POLQA)

• Latency for speech and data

Limited GPS Coverage

TETRA Active probes can be supplied with an optional on-board gyroscope and accelerometer for enhanced reporting of location when limited GPS coverage is available – e.g. in tunnels, buildings etc
