What Is Push to Talk Over Cellular (PoC) and How Does It Work?
Good communication keeps teams safe, organised, and productive. If your business works across different sites, cities, or states, staying connected can be hard with normal two-way radios.
That’s where Push to Talk Over Cellular (PoC) comes in.
Ozitel provides a modern PoC service that works across Australia using 4G and 5G mobile networks or Wi-fi. It gives businesses long range communication without the limits of traditional radio systems.
Let’s explain how it works in simple terms.
What Is Push to Talk Over Cellular?
Push to Talk Over Cellular, also called PoC, works like a walkie talkie. You press a button and speak. Everyone in your group hears your message instantly.
The big difference is this:
Traditional radios use radio signals.
PoC uses the mobile phone network.
This means your communication is no longer limited by distance. If there is mobile coverage or WiFi, your team can talk.
That is why many people call PoC an “unlimited range walkie talkie.”

How Does PoC Work?
PoC devices look like normal radios. They include:
- A Push-To-Talk button
- Speaker and microphone
- A SIM card for data
- Secure access to the Ozitel platform
When you press the button:
- Your voice travels through the 4G or 5G network.
- It reaches a secure server.
- The server sends your message to your selected group.
- Their devices play the message almost instantly.
The delay is very small (unnoticeable). It feels just like using a normal radio.

Why Is PoC Better Than Traditional Radios?
Traditional UHF radios:
- Have limited range
- Need repeaters for long distance
- Can struggle between cities
- Require infrastructure setup
PoC systems like Ozitel:
- Work across Australia
- Do not need repeaters
- Use existing mobile networks
- Support private group communication
- Offer GPS tracking and dispatch tools
If your business operates across more than one site, PoC is often the smarter option.

Who Uses Push to Talk Over Cellular?
PoC is popular in many Australian industries.
Construction
Construction sites are often large, noisy, and spread across different zones. Site managers use PoC to communicate instantly with supervisors, machine operators, and subcontractors without range limits. Teams can also stay connected between separate projects in different suburbs or cities, improving safety, coordination, and response times across all job sites.
Security
Security teams need fast and reliable communication. PoC allows guards to coordinate across multiple buildings, shopping centres, warehouses, and public events. Whether indoors or outdoors, teams can stay connected using 4G or WiFi. This helps with quick incident response, shift changes, and real-time updates across large or multi-level locations.
Transport & Logistics
Fleet operators use PoC to speak with drivers across cities, highways, and state borders. Instead of relying on short-range radios, dispatchers can manage vehicles in real time through one connected platform. This improves route coordination, delivery updates, and emergency communication without installing radio infrastructure.
Multi-Site Businesses
Businesses with multiple offices, warehouses, or branches often struggle with separate communication systems. PoC connects all locations under one network using mobile data or WiFi. Staff can talk instantly between sites without repeaters or complex setups, making it easier to scale operations as the business grows.
Factories & Cold Storage Facilities
Factories and cold storage sites often have thick concrete walls, steel frames, and large fridges that block normal UHF radio signals. Traditional radios may struggle in these environments. However, most factories already have strong WiFi throughout the building. Push to Talk Over Cellular works over WiFi or 4G, allowing clear communication across production floors, freezer rooms, and loading areas — even where radio frequencies fail.
