Location services

The market-leading DMR Tier 3 platform from Tait provides a unique blend of voice and AVL location data communications. The Tait DMR solution is designed to protect mission-critical voice performance while carrying AVL data to enhance business efficiency and safety.

AVL data for improved worker safety and efficiency

Radio systems with integrated GPS data have the capacity to save lives and improve the efficiency of utility operations. Support for AVL (Automatic Vehicle Location) and vehicle telemetry data is inherent in the DMR standard, enabling vehicles to transmit location data back to base via radio, and enhance fleet visibility. Operational management can then make more informed and efficient decisions, leading to better response times and improved worker safety and efficiency.

Tait DMR has comprehensive support for AVL data built in. AVL data from mobile and portable radios can be collected via event-driven messages and sent to the management system to provide location information. A "polling" regime can also be activated to gather and send locations from individual mobile radios as required.

Mobile radios can be programmed to "push" location data when triggered by events, while the central management system can also send a "pull" query to request location information from one or more radios.

The Tait DMR Tier 3 system enables utilities to employ their optimal balance of push and pull AVL data updates to achieve a dynamic picture of the utility workforce.

Balancing voice and AVL needs

Reaching the right balance between voice and data is a common challenge in radio communications. Voice call access remains vital to utility operations, however access for AVL data is becoming more important and requires sufficient bandwidth. The voice/AVL balance is particularly difficult to achieve during emergencies, such as natural disasters or weather events, when voice traffic fully occupies the limited channel capacity.

The Tait solution uses data compression, optimization of message paths and minimization of delays to maintain high levels of voice call capacity while still leaving bandwidth available to deliver critical location updates. The Tait DMR Tier 3 trunked network maintains an optimal balance between voice and AVL updates, even during emergencies when both can be critical to the event.

During an emergency call, the speaker's location is often very important – particularly if they are requesting help or describing a problem. The Tait DMR Tier 3 terminal can add the speakers' location data and any relevant telemetry data from their vehicle or portable onto their transmission. This up-to-date AVL information dramatically enhances efficiency and can save lives.

Telemetry provides a more informative view of operations

Tait DMR Tier 3 supports vehicle and device telemetry, a significant step forward to providing a richer and more informative view of the fleet and operational environment.

With the Tait DMR platform utilities can gather a range of telemetry data from their fleet, such as truck engine status, bucket arm status and so forth. When combined with the vehicle's location, this information can significantly enhance operational understanding.

Tait DMR Tier 3 supports many telemetry data types including telemetry gathered from portable radios. These new data sources are important to building an efficient, digital radio connected enterprise.

Tait DMR Tier 3 is the no compromise digital radio platform for AVL data.
