In today’s fast-moving industries, instant and reliable communication is essential. Whether you’re managing a logistics fleet, running a large factory, or providing public safety services—clear voice communication saves time and improves safety.
That’s where Push to Talk over Cellular radios (PoC radios) come in.
At Sole Engineering, we provide PoC solutions tailored for Malaysian businesses, helping you replace outdated walkie-talkies with smarter, broader, and license-free communication tools.
What is Push to Talk Over Cellular (PoC)?
Push to Talk Over Cellular (PoC) radios are devices that look and work like traditional walkie-talkies but use mobile networks (3G, 4G, LTE) or WiFi instead of radio frequencies.
This means you get instant push-button communication like a walkie-talkie but with nationwide or even global coverage, as long as there’s internet.
How Do PoC Radios Work?
PoC radios work through a central server or cloud-based platform. Here’s how it works:
- The device connects to the internet via SIM card (mobile network) or WiFi.
- You press a button to talk.
- The voice message is sent digitally to other devices in your group, almost instantly.
No need for repeaters, radio towers, or frequency licenses.
Key Advantages of PoC Radios
1. Wide-Area Coverage
PoC radios work anywhere there’s cellular coverage—no dead zones within Malaysia. This is ideal for:
- Logistics & delivery services
- Transportation fleets
- National construction projects
- Cross-border communication
2. No Radio Licensing Required
Unlike DMR or analog radios, PoC devices don’t require SKMM frequency licenses in Malaysia, making deployment faster and hassle-free.
3. Clear Voice Quality
Digital voice transmission ensures crystal-clear communication, even in noisy environments.
4. Real-Time GPS Tracking
Many PoC radios come with built-in GPS, allowing supervisors to track team members live.
5. Group & Private Calls
You can create talk groups by department, location, or shift. You can also send private calls—just like a phone but with push-button ease.
6. Lower Infrastructure Costs
No need for repeaters, antenna towers, or maintenance. You just need devices and SIM cards.

Common Misconceptions
❌ “PoC radios are just like mobile phones.”
Not true. PoC radios are designed for professional, real-time group communication with rugged hardware—not for personal calling or apps.
❌ “You need expensive subscriptions.”
Some providers charge high monthly fees. At Sole Engineering, we offer flexible, cost-effective SIM data plans or WiFi-based setups depending on your use case.

PoC radios use mobile networks. Since 4G/LTE covers most of Malaysia—including highways and remote towns—coverage is excellent nationwide.
