Push To Talk (PTT)

In an emergency, seconds saved can mean the difference between life and death.

To provide the best emergency response in the shortest period, Altron Nexus developed the Computer Aided Dispatch module for the Nucleus platform.

The platform intelligently finds the closest, most appropriate emergency response unit and dispatches them to the scene.

It integrates seamlessly with IoT and other applications to trigger an emergency response without anyone having to phone a call centre.

If you need business-critical communications, our Digital Mobile Radio (DMR) is the solution for you.

Push to Talk over Cellular (PTToC)

Altron Nexus offers Push to Talk over Cellular (PoC) solutions that enable our clients to communicate quickly and efficiently with their teams, regardless of their location. PoC is an advanced voice communication service that enables instant communication over 4G LTE or Wi-Fi networks using a push-to-talk button. With PoC, you can instantly connect with individuals or groups, no matter where they are, without the need for additional equipment.

PoC has a variety of uses across different industries, such as public safety, transportation, utilities, hospitality, and logistics. It is ideal for businesses that need quick and reliable communication between employees, especially in fast-paced environments. For example, in public safety, PoC can be used for emergency response, disaster recovery, and incident management. In transportation, PoC can be used to coordinate dispatch, track assets, and manage logistics. In hospitality, PoC can be used for guest services, security, and facilities management.

Altron Nexus offers customizable PoC solutions that can be tailored to your specific business needs, including hardware and software integration, API support, and user management. Our team of experts will work with you to design and implement a PoC solution that meets your communication needs and fits within your budget.
