Traditional walkie talkies have one fundamental limitation: range. The moment your team spreads across different buildings, different cities, or different states, the radio loses its signal and the communication breaks down. For decades, the only solution was expensive infrastructure — repeaters, base stations, and licensed frequency networks that put professional radio communication out of reach for many Malaysian businesses.
IP radio walkie talkies — also called PTT Over Cellular (PoC) or LTE push-to-talk radios — eliminate this limitation entirely. By transmitting voice communication over 4G/LTE and Wi-Fi networks instead of dedicated radio frequencies, PoC radios give teams the instant push-to-talk communication of a traditional walkie talkie with the unlimited coverage of a mobile network.
Sole Engineering Sdn Bhd, incorporated in 1985 and Malaysia’s experienced two-way radio communication specialist, now supplies PoC radio systems alongside their full range of analog, DMR, and TETRA communication solutions — giving Malaysian businesses a complete spectrum of options matched to their operational needs.
What Is an IP Radio Walkie Talkie (PTT Over Cellular)?
A PTT Over Cellular radio (PoC) is a push-to-talk communication device that uses mobile network infrastructure — specifically 4G LTE, 3G, and 2G networks, plus Wi-Fi — to transmit group voice communication. Unlike a traditional walkie talkie that communicates peer-to-peer on a dedicated radio frequency, a PoC radio transmits through a cloud-based dispatch platform that routes calls to all group members simultaneously, regardless of their physical location.
The key operational difference is simple: a conventional walkie talkie’s range is measured in kilometres. A PoC radio’s range is measured in coverage — wherever Malaysia’s mobile network reaches, your PoC radio works. This includes across city boundaries, between states, and even internationally.
Sole Engineering’s PoC Radio Range: T60 and M50
Sole Engineering supplies two PTT Over Cellular radio models, each suited to different operational profiles:
T60 POC Portable Radio
The T60 is a full-featured PoC radio designed for field teams and operational environments. Key specifications:
- Network: 4G LTE / 3G / 2G and Wi-Fi transmission — operates on all available Malaysian networks simultaneously
- GPS: Accurate device positioning for fleet tracking and field team location visibility
- Advanced Signalling: Radio Kill/Stun/Revive — management can remotely disable or reactivate units
- Protection: IP54 waterproof and dustproof — suitable for outdoor and light industrial use
- Operating System: Android 7.0 — supports custom PTT apps and device management
- Weight: 330g — comparable to a standard smartphone
M50 Compact PoC Radio
The M50 is a compact, vehicle-mount-friendly PoC unit for teams that need a smaller footprint:
- Compact design, easy to install for fixed vehicle or desk mounting
- 4G/3G and Wi-Fi transmission with dual SIM card support for network redundancy
- Global PTT service — works across international borders for operations spanning Malaysia, Singapore, and beyond
- IP54 waterproof and dustproof protection
- Weight: 280g
Advanced Dispatcher Software
Complementing the T60 and M50 hardware, Sole Engineering’s PTT Over Cellular system includes an Advanced Dispatcher Software powered by Kirisun Communications that gives operations managers complete centralised control over their entire radio fleet from a single desktop platform (Windows 7 or Windows 10). The Basic version covers the essentials: group calls to all members simultaneously, single calls to individual terminals, mass text messaging, real-time terminal location subscription on map, and remote Radio Kill, Stun, and Revive controls that allow dispatchers to instantly enable or disable any device in the field. The Full version adds historical voice call recording and playback, historical track query and export with GPS coordinates, and electronic geofence management allowing administrators to define boundary zones and receive automatic alerts when any terminal moves outside the designated area. The dispatcher interface displays all terminals in a live tree view with seven distinct online/offline status indicators, supports fuzzy search to quickly locate any device in a large fleet, and logs all operations locally with Excel export capability giving Malaysian businesses deploying PoC radio systems a complete command-and-control layer on top of their field communication hardware.
PTT Over Cellular vs Traditional Walkie Talkie: Which Is Right for Your Operation?
The choice between PoC and traditional analog/DMR radio depends on your operational profile. Here is a clear comparison:
- Coverage requirement — if your team operates across multiple cities, states, or countries, PoC is the clear choice. If your team operates within a single facility or site, analog or DMR radio with a repeater is often more cost-effective.
- Network dependency — PoC requires mobile network coverage. In areas with poor LTE coverage (remote industrial sites, underground facilities), traditional analog or
- Licensing — traditional VHF/UHF radio requires an MCMC frequency licence in Malaysia. PoC radios operate over commercial mobile networks and generally require only a SIM data plan.
- Fleet tracking — PoC radios with integrated GPS provide real-time team location visibility through the dispatch platform — a significant advantage for logistics, delivery, and field service operations.
- Encryption — both DMR and PoC support encrypted communication.
Industries in Malaysia Using PoC Radio Systems
PTT Over Cellular radio has been adopted across a wide range of Malaysian industries since LTE coverage matured sufficiently to support reliable group PTT communication:
- Logistics and transportation — fleet managers communicating with drivers across peninsular Malaysia without mobile call charges or WhatsApp group delays
- Security and guard services — security companies with guard teams spread across multiple sites or mall groups communicating on a unified platform
- Event management — coordinators managing teams across large venues, outdoor festivals, or multi-location events where traditional radio range is insufficient
- Construction and property development — site supervisors communicating between different project sites or communicating with head office while teams are in the field
- Hospitality chains — hotel groups communicating between properties in different cities using a single unified PTT platform
