Entropia’s ComBus application can be used with TETRA two-way radios or smartphones, using hybrid TETRA and broadband networks. A dynamic and secure directory enables you to easily locate the correct person and view their credentials. It also allows you to identify who is active or inactive. All information is updated in real-time.


Entopia's ComBus Push-to-Talk service transforms your smartphone into a PTT walkie-talkie-style device, complete with its own “Push-to-Talk” button. Other benefits of the application include comprehensive location tracking, push-to-video and much more.

Applications are compatible with Entropia TETRA and Broadband networks. Also available are hybrid TETRA / LTE broadband devices that enable connectivity to both TETRA and LTE simultaneously.

Video calls & video streaming

Live stream video capability is the smart way to increase safety and accountability.

Capturing real time video footage puts you directly at the scene. It supplies live visual and audible data to optimise the safety of your front-line personnel and the public, provide essential evidence and increases response times.



Providing front-line personnel with the technology to capture and stream live footage from a body-warn video ensures that they always act as a team. With every member of your team aware of a situation, and to witness its events unfold at the same time, empowers them to work together for the optimal outcome.

The wearing of a body camera instils confidence. Knowing that the event is being accurately recorded enables the wearer on the front-line to focus and assess the situation.

Business Critical versus Mission Critical?

To make it easier to understand our definitions of service we have put together this simple explainer section. But first here is an introduction to our company.

Entropia provides TETRA and Broadband two-way voice and data communication services. Entropia's ComBus & Combonet together provide a catalogue of cloud-based apps that connect people and key equipment together across all technologies and networks.



Mission critical is the essential communications service provision for blue light and pale blue light operations including police, fire, ambulance, security, and the utility sector. All these organisations have demanding communications requirements.

Mission critical delivers instant call setup and instant data messages, both with a greater than 99.999% call setup guarantee even if the carrier infrastructure is congested. This is our definition of mission critical, and a pledge we stand by.

To achieve this grade of service, the network operator must ensure absolute continuity of resources and connectivity for a pre-determined operation area. There cannot be any third-party resources that the network provider cannot fully control.



The TETRA infrastructure is totally owned, controlled, and managed by Entropia meaning that continuity of resource can be guaranteed. Entropia has over 30 years’ worth of experience in voice and data networks. TETRA remains the most popular choice for mission critical services across the world today.



Yes, however for this broadband service to be graded as Mission Critical the end-to-end service and infrastructure must be a private network with all the resources being controlled and managed by either Entropia or by the organisation using the service. There cannot be any third-party resources that the network provider cannot fully control.



No, we do not class it as mission critical, this is because we use partner networks in over 176 countries accessing 500+ tier 1 networks to provide connectivity.

Our provisions rely on our service partner networks to provide connectivity which grades the service as Business Grade. Business Grade communications still provides a high grade of service suitable for many organisations, but with less emphasis on protecting and saving lives.



Yes, ComBus’ catalogue of applications can be used on both grades of network. Only the network they operate on can determine if the use is mission critical or broadband critical. ComBus as such is always mission critical.
