PoC vs UHF Radios: Which Is Better for Business in Australia?

When choosing a communication system for your business, one big question comes up:

Should you use traditional UHF radios or switch to Push to Talk Over Cellular (PoC)?

Both systems allow teams to speak instantly. Both are used across Australia. But they work very differently.

Let’s break it down in simple terms so you can decide what is best for your business.

What Are UHF Radios?

UHF (Ultra High Frequency) radios are traditional two-way radios. They use radio frequencies to send voice signals between devices.

They are popular in:

• Construction sites
• Small warehouses
• Events
• Farms
• Local security teams

UHF radios work well over short distances. In open areas, they may cover a few kilometres. In built-up areas with walls and buildings, the range is often much shorter.

If you need longer distance, you must install a repeater. This increases coverage but also increases cost and setup time.

What Is PoC (Push to Talk Over Cellular)?

Push to Talk Over Cellular (PoC) works like a walkie talkie, but instead of radio frequencies, it uses 4G or 5G mobile networks.

That means the communication range is no longer limited by distance. As long as there is mobile coverage or WiFi, your team can talk.

Ozitel provides a nationwide PoC Service Australia businesses can use across cities, states, and even internationally.

Key Difference #1: Coverage & Range

UHF Radios

• Limited by distance
• Blocked by thick walls or hills
• Often need repeaters for wide areas

PoC Radios

• Use Australia’s mobile network
• Work across cities and states
• No repeaters required
• Operate anywhere with 4G, 5G, or WiFi

If your business operates across multiple locations, PoC gives you much wider coverage.

Key Difference #2: Infrastructure & Setup

UHF Setup

• May require licensed frequencies
• May require repeater towers
• Needs installation planning
• Maintenance required

PoC Setup

• Requires compatible device
• SIM card with data
• Subscription plan
• No tower installation

PoC systems are much easier to scale. You simply add more devices to the network.

Key Difference #3: Indoor Performance

UHF radios can struggle inside:

• Concrete buildings
• Shopping centres
• Factories
• Cold storage facilities

Radio signals weaken when blocked by thick walls or steel.

PoC devices can use WiFi inside buildings. This makes them more reliable for large warehouses, offices, and industrial sites with strong internal networks.

Key Difference #4: Multi-Site Businesses

This is where PoC becomes very powerful.

With UHF:

Each site often has its own radio network.

You cannot easily talk between:

• Sydney office and Brisbane office
• Warehouse and head office
• Field team and dispatch centre

With PoC:

All devices connect to the same network.

Your head office can talk directly to field staff anywhere in Australia.

Fleet drivers can speak to dispatch in real time using Mobile PTT Radios.

That makes PoC ideal for transport, logistics, security, and national operations.

Key Difference #5: Extra Features

Traditional UHF radios mainly provide voice communication.

PoC systems like Ozitel offer more advanced features:

• GPS tracking
• Group management
• Emergency alerts
• Dispatch console software
• Private user groups
• Remote management

This makes PoC a full communication platform, not just a radio.

When UHF Might Be the Better Choice

UHF radios can still be useful for:

• Small job sites
• Short-distance communication
• Areas without mobile coverage
• Temporary local events
• Low-budget short-term use

They are simple and effective for close-range use.

When PoC Is the Better Choice

PoC is often better when:

• Your team works across large distances
• You operate in multiple cities
• You manage vehicle fleets
• You need head office to talk to field teams
• You want easy expansion
• You want GPS and management features

For businesses that need flexible and scalable communication, PoC is usually the smarter long-term investment.

Cost Considerations

UHF radios:

• Lower upfront device cost
• May require repeater setup
• Maintenance costs over time

PoC systems:

• Subscription-based service
• No repeater infrastructure
• Lower expansion cost
• Easier management

While PoC involves ongoing service plans, it often reduces infrastructure and maintenance costs.

So, Which Is Better for Your Business?

There is no single answer.

If your business is small, operates in one location, and only needs short-range communication, UHF may work well.

But if your team works across suburbs, states, or multiple sites, Push to Talk Over Cellular provides:

• Wider coverage
• More flexibility
• Better scalability
• Modern communication tools

Most growing Australian businesses are moving toward PoC because it removes the limits of traditional radio systems.
