Professional Mobile Radio, as distinct from Public Access Mobile Radio, utilises channels, frequencies or networks specifically dedicated to particular user groups. This includes government bodies such as police, fire, ambulance and other key public services. Professional Mobile Radio has also long been accessible to a range of commercial and business users who rely on two-way communication between a base unit or control centre and multiple mobile working units; perhaps most visibly in the taxi and transportation sectors but also for airports, security, construction, hospitality and a range of other industries.
Traditionally, these radio systems have broadcast using VHF and UHF bands on channels allocated for professional use, relying on the using land-mobile radio infrastructure. This long-standing technology has served business users well in many ways over the years. The key benefit being a communication system which is ‘always on’ and therefore always ready to send and receive one-to-many voice communications instantly. In addition, traditional radio systems provided business users with simple ‘push to talk’ operation which allowed any unit to communicate at the press of a button.
The drawbacks of land-mobile radio include the limited space available on the radio spectrum in a context of increasing demand and the lack of reliable coverage. Spectrum is a finite resource and when it’s fully utilised providing expansion capability can be costly and complex. This can cause significant problems where users are spread over wider geographical areas or remote locations or, at the other end of the scale, where interference is experienced due to buildings in urban areas or the signal is blocked by the structure the user themselves is inside.
In common with technological advances in the wider world, Professional Mobile Radio has been undergone a transition from analogue to digital and has now moved towards internet-based two-way radio communications for professional use. Although this addressed some of the issues associated with the finite radio spectrum, until recently many internet-based two-way radio systems failed to deliver many of the key benefits business users enjoyed in the traditional analogue system. Most importantly, the use of SIP (or Session Initiation Protocol) from telephone conference calling meant that set up was required and the instant, ‘always on’ functionality was hampered.
Today, Hydra’s high-speed broadband networks, dedicated to two-way communications, represent the leading edge, new generation of digital radio communications for professional users. Built around the new and revolutionary Intelligent Radio Protocol (IRP®), our networks are designed to support ‘always on’ two-way communication systems for instant connections, along with all of the other key benefits of traditional two-way radio. Going beyond this, our networks provide coverage reaching over 99% of the Australian population including superior reach in remote areas and within buildings and underground locations. The speed and capacity of our broadband networks also support a range of additional communication options including picture messaging and data transfer. The situational awareness associated with traditional two-way radio is not only maintained but brought into the internet age with advanced control and command solutions offering real-time mapping and visualisation tools.
