In a similar way to how VOIP (Voice Over Internet Protocol) has revolutionised land line telephony, Radio over IP is doing the same with LMR (Land Mobile Radio) for both traditional analogue and digital radio users that require wide area coverage communication. Truly commercial grade solutions however are very different.
TR Telecom’s Wide Area Coverage Communication (WACC) solution:
Designed, developed and managed in Australia, RAPID PTT utilises a completely new proprietary protocol designed specifically to replicate the usage behaviours, volume of calls, number of users and groups associated with LMR wide area coverage requirements.
Whilst at face value, it may be easy to compare our solution to other inferior PTToC offerings, especially in low volume demonstrations and usage, the difference between RAPID PTT and others becomes undeniable as more users, channel groups, and call volumes increase.
As important as maintaining speed and quality of communication as call volumes increase, the RAPID PTT protocols enable increased features and functionality to be added to the system without compromise and experience degradation, and underpins our commitment to continuous improvement.
There are an increasing number of “solutions” and software coming into the market purporting to offer PTToC as a valid alternative to LMR repeater networks, they are unfortunately nothing more than Voice over IP – a telephone call using a Push-to-Talk function on a device to make what is effectively a conference call.
They use a combination of protocols used fundamentally within IP landline based VOIP systems known as SIP & RTP.
SIP (Session Initiated Protocol)
– Used to establish/set up a call (known as a session)
RTP (Real Time Transport Protocol)
– Used once a “call” is established to exchange voice (actually data) packets between users
SIP/RTP based solutions provide the resemblance of a traditional LMR PTT experience in the sense the user can initiate a “voice” call to a number of users on the same group (channel), however all that is effectively occurring is a standard daisy chain conference call.
These SIP/RTP solutions are prevalent, yet not suitable for business and commercial applications that require traditional DMR communication styles and behaviours as they don’t provide real One-To-Many simultaneous communication.
Traditional LMR users requiring wide area coverage communication have in the past been confined to subscribing to one of a number of Land Mobile Radio (LMR) or Digital Mobile Radio (DMR) networks generally owned and operated by organisations of varying sizes.
These “networks” are effectively a series of frequency repeaters positioned in varying locations (usually in main cities) to extend a given set of frequencies that users have subscribed to.
Larger networks, spanning a number of cities were “linked” to provide extended radio frequency coverage, however, the cost of establishing, maintaining and ongoing development of what is effectively “narrowband” frequencies was/is expensive and as a result the level of investment in these networks has stagnated and in some cases been withdrawn. Evidenced with a number of networks being discontinued.
In the face of increasing levels of investment required to achieve a truly reliable and expansive LMR network, and the continual development and improvement of the cellular broadband networks, now 4GX and the imminent 5G, alternative solutions for traditional LMR network users has arrived.
TR Telecom and its partners have a true replacement for traditional land mobile narrowband systems such as DMR, DMR3, TETRA, and conventional systems.
Our focus is to provide unprecedented high speed and high quality voice performance, delivering an instant voice experience already familiar to you. TR Telecom’s Wide Area Coverage Communication (WACC) solutions removes the limitations of traditional narrowband systems (such as coverage and data speeds) and unlocks data integration, enterprise applications, and the broader world of Internet-of-Things (IOT).
