Service from the Start - Setting a new standard for service

Our Service from the Start Program offers a range of support packages to protect your Motorola MOTOTRBO™ radios against normal wear and tear, accidental breakage and more. Each package comprises expert repair and technical support, designated turnaround times and access to the latest software updates.

Hear The Difference

When it comes to exceptional audio clarity, the quality of digital cannot be surpassed. With MOTOTRBO™ radios, you enjoy digital quality with background noise suppression plus unique features like Intelligent Audio for automatic adjustment of radio volume to compensate for background noise. Helping your workforce hear and speak clearly, wherever they work.

Double your call capacity

One of the principle benefits of DMR is that it enables a single 12.5kHz channel to support two simultaneous and independent calls, achieved using TDMA Under the DMR standard, Time Division Multiple Access (TDMA) retains the 12.5kHz channel width and divides it into two alternating timeslots A and B (illustrated in figure 1 below) where each timeslot acts as a separate communication path. In figure 1 Radios 1 and 3 are talking on time slot 1 and Radios 2 and 4 are talking on timeslot 2.   

Get the most out of your system

Another advantage of the DMR TDMA approach is that you get two communications channels with one repeater, one antenna and a simple duplexer. Compared to FDMA solutions, two-slot TDMA allows you to achieve 6.25 kHz efficiency while minimising investments in repeaters and combining equipment. The required equipment of the two approaches for a simple system is shown in figure 6 below.    

Longer battery life and greater power efficiency

One of the biggest challenges with mobile devices has always been battery life. In the past, there have been limited options for increasing the talk time on a single battery charge. Two-slot TDMA, however, offers a good way forward. Since an individual call uses only one of the two timeslots, it requires only half of the transmitter’s capacity. The transmitter is idle half of the time — that is, whenever it’s the unused timeslot’s “turn”.
