Two Way Radio Singapore: Essential 2026 Buyer's Guide

Choosing a two way radio in Singapore in 2026 is harder than it looks. Spec sheets make every model sound identical, IMDA licensing rules confuse first-time buyers, and the shift from traditional digital radios to cellular push-to-talk has changed what "best" actually means.

This guide explains what a two way radio does, which IMDA licence applies to your use case, which Motorola and Hytera models still dominate, and when a PTT over Cellular solution is the smarter choice for Singapore businesses.

What a two way radio does and why Singapore businesses still use it

You will learn why the two way radio remains a core tool for Singapore security, construction, logistics, and event teams despite the rise of mobile phones.

A two way radio is a handheld device that transmits and receives voice over radio frequencies, letting one person reach a whole team with a single button press. Unlike a phone call, it is instant, group-based, and does not require dialling or waiting for a connection.

Two way radios have been in use since World War II, and the technology has moved from analogue voice to digital DMR platforms, and now to 4G and 5G broadband radio running on cellular networks. Each generation has kept the same core benefit: fast, one-to-many communication that works under pressure.

In Singapore, the main industries relying on two way radios are security services, construction, logistics, hospitality, healthcare, and event management. Phones do not replace them because a phone ties up one person at a time, while a radio keeps the whole team on the same channel.

IMDA licensing rules for two way radios in Singapore

You will learn the three IMDA licence categories that apply to two way radio use in Singapore and which one fits your operation.

Singapore regulates two way radio use more strictly than most countries. The Infocomm Media Development Authority (IMDA) controls which frequencies and power outputs are allowed, and businesses must hold the correct licence to operate legally. Getting this wrong can lead to penalties and equipment seizure, so it is worth matching your use case to the right category before buying.

Licence-free radios

Licence-free two way radios can be bought over the counter and used without any annual IMDA permit. They are capped at low output power and operate on shared channels, which means interference from other users is common. These are suitable for casual or very short-range use, but not for serious business operations.

Localised Private Network (Multi-Channel Radio-Communication) Licence

This licence covers businesses running a walkie talkie network within a single location, such as a warehouse, hotel, or event venue. According to IMDA, the network must have at least 2 sets of radio equipment, output is limited to 1 watt ERP, and channels are pre-set in the 446.325 MHz to 446.475 MHz range. Full details are available on the IMDA licensing portal.

Wide-Area Private Network Licence

This licence is for operations that need coverage beyond a single site, such as a property management company overseeing multiple buildings or a logistics firm covering a large industrial area. It allows higher power output and dedicated frequencies, but requires working with an IMDA-licensed dealer who can programme and register the equipment.

Public Trunking and its replacement

Singapore used to have a public trunking service called Grid, which offered islandwide walkie talkie coverage through a network of base stations on the IDEN platform. That service has since been discontinued. Today, the equivalent capability is delivered through PTT over Cellular solutions that ride on the existing 4G and 5G telco networks, giving you the same islandwide reach without building base stations or installing Distributed Antenna Systems inside buildings.

Popular two way radio brands and models in Singapore

You will learn which Motorola and Hytera models dominate the Singapore commercial market and why long product lifecycles matter.

Two companies lead the commercial two way radio space in Singapore: Motorola and Hytera. Both have built their lineups on the Digital Mobile Radio (DMR) standard, which delivers clearer audio, better battery life, and stronger encryption than older analogue models.

Motorola two way radio models

Motorola remains the most recognised name in the category, backed by decades of reliability in field use.

Motorola XiR P3688 

The Motorola XiR P3688 is a mid-tier digital portable radio built for frontline workers in construction, warehousing, and security. It offers solid audio clarity, a durable housing, and long battery life suited to full-shift use.

Motorola XiR P6600i 

The Motorola XiR P6600i sits higher in the range, with advanced features such as integrated Bluetooth, text messaging, and improved noise suppression. It is often chosen by teams that need cleaner audio in high-noise environments or more flexibility in device-to-device features.

Before these, the Motorola GP328 held the Singapore market for more than 20 years, which tells you something about how slowly this category moves.

Hytera two way radio models

Hytera has built a strong following among Singapore buyers looking for capable digital radios at a more competitive price point.

Hytera PD708

The Hytera PD708 is a professional-grade portable radio with a colour display, GPS capability, and encrypted communications. It is often deployed in security, public safety, and transportation roles.

Hytera PD508

The Hytera PD508 is a lighter, entry-level DMR radio aimed at teams that need reliable digital voice without the advanced features. It works well for retail, hospitality, and smaller security operations.

Why these models have stayed on the market for so long

All four models have been around for more than five years. Long product cycles bring real advantages for buyers: bugs are fixed, accessories are easy to source, and replacement parts stay available. Your existing fleet does not become obsolete the moment a new model launches.

The trade-off is that if your team has a requirement these models do not cover, such as a built-in camera, an ATEX-certified body, or a larger screen for work apps, you are forced to either carry a second device or look beyond traditional DMR radios entirely.

Why PTT over Cellular is changing the two way radio market in Singapore

You will learn how PTT over Cellular works, what it replaces, and why it fits modern Singapore operations better than traditional DMR in many cases.

PTT over Cellular (PoC) delivers push-to-talk communication through 4G and 5G mobile networks instead of dedicated radio frequencies. Your team gets the same one-button, group-call experience of a walkie talkie, but the signal travels over the same cellular infrastructure your phone uses.

For Singapore, this solves several problems at once. Coverage is islandwide out of the box, because the telco network already reaches almost every corner of the country. You do not need to build repeaters, install a Distributed Antenna System inside a building, or worry about line-of-sight gaps between floors of a mall.

PTT over Cellular also scales up and down without hardware changes. Adding a user means adding a SIM and a device, not installing more infrastructure. This matters for security companies that scale up for events, construction teams that move between sites, and logistics firms with drivers covering the whole island.

Modern PoC devices also combine a walkie talkie, a smartphone, and a work tablet into one unit. That is a meaningful change: a security officer no longer needs to carry a radio for the team channel and a separate phone for client calls. Smartcom offers a range of PTT devices and intrinsically-safe phones from brands including Samsung, Hytera, Sonim, iSafe, and ecom for exactly this reason.

How to choose the right two way radio for your business

You will learn the key questions to answer before committing to a two way radio purchase or rental in Singapore.

Match your equipment to your operation, not to the latest spec sheet. The right choice depends on where your team works, how many users you need to connect, and whether coverage stays within one site or spans the whole island.

• Single-site operations (hotel, warehouse, event venue): A Localised Private Network setup with DMR radios like the Motorola XiR P3688 or Hytera PD508 is often the most cost-effective choice. Coverage is predictable, licensing is straightforward, and the devices last for years.

• Multi-site or islandwide operations: A PTT over Cellular solution is usually the better fit. You avoid infrastructure cost, you get coverage wherever Singtel has signal, and you can integrate features such as GPS tracking, lone worker protection, and video calling into the same device.

• Short-term needs (one-off events, temporary projects): Walkie talkie rental makes more sense than buying. You skip the capital outlay, you get devices already programmed and ready to use, and you return them once the job is done.

• Productivity Solutions Grant (PSG): Singapore businesses can tap this grant when adopting qualifying PTT systems, which reduces the cost of upgrading an older radio fleet. The full process for applying runs through. .

Here’s a fun fact, the top of Mt Everest now has 5G and people from base camp no longer needs to rely on walkie-talkies anymore and theoretically, someone at the peak can actually upload a picture of themselves or stream it to the whole world. What this shows is how the lack of product innovation can actually open up other innovations that we sometimes wouldn’t even think off.

Final thoughts on choosing a two way radio in Singapore

The right two way radio for your team depends on your coverage needs, team size, and whether your operation runs within a single location or across the whole island. Traditional DMR radios from Motorola and Hytera still serve most single-site businesses well, while PTT over Cellular has become the better choice for multi-site teams, event coordination, and any operation that needs to combine voice, data, and GPS in one device.
