The Future Of Radio

Don't Get Left Behind in the Digital Revolution

Communications is evolving rapidly, more rapidly than many people realise.  Like computing, it is becoming increasingly 'application' driven.  In order to maximise the advantage that the new applications can bring, a solid and technically advanced infrastructure is required over which to deploy them; MOTOTRBO is it.

Any organisation wanting to maximise their operational effectiveness and overall efficiency needs to be planning their migration to digital now.  The process is painless and far less costly than many people realise.  To find out more and for a free review of your existing communications and a detailed, professional report on what digital can do for you.

Why Digital Two-Way Radio

You know the challenges.  

• You need to ensure the safety and security of your personnel and vehicles.
• Increase productivity as costs escalate.
• Optimise operational procedures, responding quickly to unexpected changes or problems.
• And ensure the fastest response in case of emergencies.

Powered by advanced Motorola technology, the MOTOTRBO Professional Digital Two-Way Radio System is ready to help you respond to those challenges.

The Digital Difference

Analogue two-way radio proves itself every single day in countless installations around the world.  Today a new platform is available to help you to achieve new levels of operational performance and effectiveness.  Digital technology enables that breakthrough.

Many organisations now need more than the fundamental services that analogue two-way radio can deliver and the digital technology provides a powerful, flexible platform that can be adapted to meet these ever changing, and more demanding needs.  Digital provides:  

• Expanded digital voice, data and control capabilities over a given network channel.  With digital two-way radio you get increased capacity over the same slice of radio spectrum; in the real world this means that one repeater will now give you two traffic channels, instantly doubling your network capacity.
• Clearer voice communications over a greater range.  When signal strength drops off with distance, digital error-correction technology can accurately deliver both voice and data with virtually no loss over a far greater distance.
• Static and noise rejection.  Analogue signals become distorted, producing audible static as signal strength degrades.  By contrast, digital receivers simply reject anything they interpret as an error.
• Enhanced battery life.  Each individual transmission only uses half the battery power of an analogue transmitting at the same wattage (RF power) resulting in more up-time per battery charge.
• Additional functionality.  Sophisticated dispatch systems with integrated tracking of all radios.  Mobile data and text messaging.  Interfacing with back office systems and Bluetooth linking with PDA's and other data devices are all available over the digital network.
• Easy migration because the MOTOTRBO radios can operate in analogue and digital modes allowing the gradual replacement of your existing analogue legacy network.  This includes repeaters that can be swapped out and set up to operate in analogue mode today for a digital switchover at a later date.

The Technology

MOTOTRBO utilises an advanced communications technology called TDMA.  This stands for Time Division Multiple Access.

Put simply, it slices the existing 12.5kHz communications channel into two time slots and each one takes a turn to transmit and receive.  In reality this happens so quickly that you do not realise that you are, effectively, sharing the channel with another conversation, which can be either voice or data.  The synchronisation of the timeslots is carried out by the repeater or repeaters, but the bulk of the intelligence resides within the handset or mobile terminal, making it a truly versatile and feature rich proposition.

Actually, we are all familiar with this method although many will not realise it.  Most modern cellular telephone networks use the same technology, splitting the channel 'bandwidth' into as many as 8 timeslots and 'interleaving' them all together so that everyone gets an equal turn.  Again, this happens so quickly as to not be noticeable to the user.

As well as delivering fantastic benefits to the end users, it also has a wider impact by making more efficient use of the available Radio Frequency spectrum; channels that historically carried a single call are now being divided so they can carry two, benefiting all other two-way radio users.
