What is RAPID?

RAPID is the next generation of instant, high-speed, and secure two-way radio communications for voice and data. Designed and built on a revolutionary all-Australian secure protocol, Intelligent Radio Protocol® (IRP®) to ensure true one-to-many communication performance. Purpose developed to outperform traditional LMR two-way radio solutions, RAPID's push-to-talk over cellular technology delivers exceptional performance when placed against the key functional performance criteria of traditional LMR.

IRP® “The Brains” of RAPID

Intelligent Radio Protocol® (IRP®), is a high-speed, two-way radio communications protocol designed to address the many challenges found in traditional land mobile solutions. Fully designed and supported by Australian industry experts, IRP® is the software that drives RAPID and is revolutionising two-way radio communications.

Why RAPID and IRP® is the better choice.

Designed, developed, and managed in Australia, RAPID utilises a completely new proprietary protocol - IRP, designed specifically to replicate the usage behaviors, 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 push-to-talk over cellular (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 protocols enable increased features and functionality to be added to the system without compromise and experience degradation and underpins our commitment to continuous improvement.

What RAPID is not!

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, but, 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.

Voice over IP (VoIP)

• The PTT initiates the process to find and assign radios in the group to a talk channel.
• 1.1 sec to set up the first one-to-one call, with added latency adding more users to the group.
• At 1.1 sec one radio is found and moved to a talk channel additional time is required to find and assign the rest of the group.


• All radios are always listening to a talk channel
• True One-To-Many Communication
• No delays with large groups sizes
• 80 m/sec and you are talking to the whole group regardless of size
