Frequently Asked Questions

How Far Can Two-Way Radios Reach?

Two-way radios operate using line-of-sight communication, which means buildings, hills, steel structures and other obstacles can affect range. Actual distance depends on the environment, radio power, antenna type and system setup.

Typical examples:

• Small offices or retail: hundreds of metres
• Warehouses and construction sites: 1–3 km
• Open outdoor areas: several kilometres
• Repeaters or Push-to-Talk over Cellular systems: Australia-wide coverage

If coverage is critical, Radio Industries can help design the right communication solution.

What Channels Can I Use?

In Australia, radios can operate on:

• UHF CB channels (1–80) – public shared channels available for general use
• Private licensed frequencies – dedicated channels licensed through ACMA for business use
• Digital radio systems – for improved audio and advanced features
• Push-to-Talk over Cellular (PoC) – communication over mobile networks and Wi-Fi

The right option depends on your application and operating environment.

Which Radio Is Best?

There is no one-size-fits-all answer. The best radio depends on:

• Your industry
• Required coverage area
• Team size
• Indoor or outdoor use
• Safety requirements
• Noise levels
• Whether you require UHF CB, licensed channels or nationwide communication

A warehouse team may need digital radios, while transport fleets may benefit from Push-to-Talk over Cellular systems.

Do I Need A Private Frequency?

Not always. UHF CB channels are suitable for many general communication applications.

However, private frequencies are recommended where:

• Communication is safety critical
• Teams operate around cranes or major construction projects
• Privacy is important
• Multiple users share the same location
• Interference must be minimised

Dedicated channels help improve reliability and reduce unwanted outside traffic.

What Is The Difference Between a Two-Way Radio, Walkie Talkie and Handy Talkie?

They generally refer to the same type of device.

In professional environments, Two-Way Radio is the preferred industry term. “Walkie Talkie” and “Handy Talkie” are commonly used for recreational or consumer products.

What Is The Difference Between Analogue and Digital Radios?

Analogue radios use traditional radio technology and are often suitable for basic communication requirements.

Digital radios provide:

• Clearer audio quality
• Better noise reduction
• Longer battery life
• Improved coverage performance
• Advanced features such as private calling and GPS

Digital systems are commonly used by businesses requiring higher performance and reliability.

What Is Push-to-Talk Over Cellular (PoC)?

Push-to-Talk over Cellular works like a two-way radio but uses 4G, 5G and Wi-Fi networks instead of traditional radio signals.

Benefits include:

• Australia-wide coverage
• GPS tracking
• Group communication
• No repeater infrastructure required
• Easy expansion across multiple locations

This solution is ideal for transport, security, events and nationwide operations.

Can Two-Way Radios Work Australia-Wide?

Traditional radios have distance limitations unless repeaters are used.

For nationwide communication, many businesses choose Push-to-Talk over Cellular systems, which operate across mobile networks and Wi-Fi.

Can Different Brands Of Radios Communicate Together?

Sometimes.

Compatibility depends on:

• Frequency settings
• Channel programming
• Analogue or digital mode
• Signalling protocols (IDAS, DMR, NXDN, TETRA, P25)
• System configuration (Capacity Plus, Capacity Max, P25)

Even radios from different manufacturers may communicate if correctly programmed.

Do Radios Need Programming Before Use?

Many professional radios require setup before deployment.

Programming may include:

• Channel configuration
• Private frequencies
• User groups
• Emergency functions
• Scan lists
• Button customisation

Radio Industries can pre-program and configure systems before dispatch.

Can I Use Headsets With Two-Way Radios?

Yes. Many industries use headsets and accessories to improve communication and safety.

Popular options include:

• Noise-cancelling headsets
• Hearing protection communication headsets
• Earpieces
• Remote speaker microphones
• Push-to-talk accessories

These are commonly used in construction, security, industrial sites and events.

Are Two-Way Radios Waterproof?

This depends on the model.

Many commercial radios include protection ratings such as:

• IP54 – Protected against limited dust ingress and resistant to water splashes from any direction. Suitable for indoor use, retail, warehouses and light outdoor environments.
• IP67 – Fully protected against dust and can withstand temporary immersion in water up to 1 metre for up to 30 minutes. Commonly used on construction sites, security operations and harsh environments.
• IP68 – Fully dustproof with enhanced water protection beyond IP67 standards. Exact depth and duration vary by manufacturer, but these radios are designed for more demanding environments with heavy dust, rain and exposure to water.

The right rating depends on your work environment.

Can Radios Be Used On Construction Sites?

Yes. Two-way radios are widely used across construction projects for coordination, safety and productivity.

Many sites use:

• Rugged digital radios
• Hearing protection headsets
• Vehicle-mounted radios
• Dedicated licensed frequencies

Radio Industries can recommend systems suited to site conditions and OH&S requirements.

Do You Offer Repairs And Ongoing Support?

Yes.

Radio Industries provides:

✔ Repairs and servicing
✔ Programming and setup
✔ Genuine parts and accessories
✔ System upgrades
✔ Technical support
✔ Australia-wide assistance

We support customers long after the initial purchase.
