From Two-Way Radios to Push-To-Talk Over Cellular: A Market Shift

By April 2026, more than 2 million of the connections on FirstNet were connected devices rather than handsets, according to AT&T. Voice now shares the network with cameras, sensors, and telemetry, which explains why push-to-talk keeps migrating onto cellular. The same pressure reaches loading docks, hospital floors, and school campuses.

Teams that spent decades on repeaters and licensed channels keep running into the same three walls: coverage that stops at the property line, spectrum licenses that cost money and patience, and radios that carry voice and little else.

Meanwhile the device in every pocket handles group calling, mapping, and messaging over networks somebody else maintains. Legacy TETRA networks and analog fleets still do the job, but the economics underneath them have shifted, and buyers have started to notice.

That does not mean traditional land mobile radio is disappearing. Quite the opposite. According to Coherent Market Insights (CMI), the Land Mobile Radio (LMR) Systems Market is estimated at USD 30,624.7 Million in 2026 and is expected to reach USD 68,125.7 Million by 2033, growing at a CAGR of 12.1% from 2026 to 2033. Public safety, transportation, utilities, industrial operations, and other users still depend on LMR when dependable voice communication matters most.

The change is really about what gets added around the radio. Broadband networks, connected devices, location services, and data applications are making buyers look for communications systems that can do more than voice.

How Push-to-Talk Over Cellular Works

PoC keeps the part of the radio experience people care about. Press the button, talk, release. Voice reaches the whole talk group in under a second. The difference sits underneath: instead of a private frequency and a rooftop repeater, audio travels as data packets across LTE, 5G, or Wi-Fi.

That shows up in a few forms

• Push-to-talk radios that look and feel like traditional handsets, with rugged bodies and a physical PTT button
• PTT apps that turn existing smartphones into walkie-talkies
• Dispatch consoles that let a supervisor call any talk group from a browser

Coverage becomes the carrier footprint. A crew in one state can key up and reach a manager in another, no tower required.

Privacy changes along with it. An analog channel stays open to anyone with a scanner in range, while PoC providers like Peak PTT encrypt traffic end to end and control who joins each group, which matters for teams reading out gate codes, patrol routes, and customer details over the air.

This shift is part of a larger change in the LMR market. CMI divides the LMR Systems Market by type, technology, frequency, application, and region. Its technology segmentation includes digital and analog systems, while applications include areas such as public safety, commercial, transportation, utilities, mining, and other industrial uses. Digital systems are becoming more important as organizations look for better spectrum use, stronger features, and easier integration with modern communication tools.

One of the key trends in the LMR market is the shift from analog to digital systems. Digital LMR offers better communication capabilities and makes it easier to add features such as messaging, location services, and other data applications. This is encouraging organizations to upgrade older radio fleets while keeping the reliability they already depend on.

Why Two-Way Radios Held On

Two-way radios earned their place. They work when the network is congested. They run on private channels no carrier can throttle. They survive the drops, dust, and rain that would end a consumer phone in a week.

That reliability keeps money moving: the land mobile radio systems market is estimated at USD 30.6 billion in 2026, and public safety agencies remain heavy buyers. Nobody replaces a working P25 system because a brochure told them to.

CMI expects the mobile type segment to account for 60.9% of the LMR Systems Market in 2026. Its strong position reflects the continued need for secure and reliable communication for teams working across large areas.

The trouble starts when growth outpaces the original design. Add a second site, a rural route, or a partner agency on a different frequency band, and the system needs more hardware, more licensing, and more integration work. Coverage becomes a capital project rather than a settings change.

At the same time, the traditional walkie-talkie remains relevant for many smaller teams and short-range jobs. CMI estimates the Walkie Talkie Market at US$4.94 billion in 2026, with the market expected to reach US$8.69 billion by 2033. These devices continue to find use in construction, hospitality, events, retail, security, and other environments where simple, direct communication is enough.

The difference is that buyers now have more choices. A team working inside one building may still need nothing more than a set of walkie-talkies. A company with crews moving across cities or states may find a cellular-based system more useful.

The Costs That Sit Outside the Purchase Order

Radio budgets tend to hide their real shape. The handset price is visible. Most of what supports it is less so

• Licensing fees, renewals, and frequency coordination
• Repeaters, antennas, and the rooftop or tower leases that host them
• Battery replacement cycles and depot repairs
• Technicians who can program and align digital radios

Compare that with a PoC subscription, where the network becomes somebody else's operating expense. The temptation is to read this as a straight cost cut, and that can be a mistake. Monthly fees accumulate. Over seven years, a large fleet on subscription can cost more than an owned system that was paid off years ago.

So which cost would you rather control: a capital expense you own outright, or a line item that scales with every badge you issue?

The answer will differ by organization. A public safety agency with its own infrastructure has different needs from a logistics company with drivers spread across several states. That is one reason both LMR and PoC continue to have a place in the market.

What Public Safety Migrations Reveal

The clearest evidence sits in government programs, where the switch gets documented in public.

The UK has been moving its emergency services from the Airwave TETRA network to a 4G-based Emergency Services Network for more than a decade. In the Home Office business case published in July 2026, Airwave stays live under extended arrangements until a safe shutdown, with the broadband service delivered in phases and tested alongside the network it replaces.

Commercial rollouts follow similar logic. Motorola Solutions launched WAVE PTX in Peru in July 2025, connecting work teams across 3G, LTE, Wi-Fi, and LMR networks through one subscription service.

Nobody in these programs pulled the radios out on a Friday afternoon.

That gradual approach says something important about the wider market. Digital and broadband technologies are being added because organizations want more capability, but reliability still matters. For many users, the practical path is to connect existing LMR systems with newer networks rather than replace everything at once.

Where Cellular Still Falls Short

Sub-basements, deep mines, offshore platforms, tunnels, and open rangeland still defeat public networks. A carrier can add capacity, though coverage follows population and revenue, not your jobsite.

Congestion is the second issue. During a stadium event or an evacuation, consumer traffic can crowd the same telecom towers your crew depends on. Priority and preemption services exist for this, and they carry an extra line on the invoice.

Then there is dependency. If the network drops, an owned radio system keeps running on its own repeaters. A PoC fleet with no fallback goes quiet, and a team that loses voice coordination mid-shift can be flying blind at the worst possible moment. Coverage maps deserve a walk test, not a screenshot.

These limitations explain why LMR remains important even as cellular push-to-talk grows. CMI identifies reliability, secure communication, wide coverage, and the need for real-time communication among the factors supporting demand for LMR systems. At the same time, the market is being pushed toward more flexible and connected solutions as users expect data services alongside voice.

Hybrid Systems Are the Practical Middle

Vendors spotted this standoff before buyers did. Multi-network radios now sit in nearly every catalog, running LMR and broadband inside one body. Motorola's MOTOTRBO Ion and Hytera's PNC380 both operate across LMR and cellular, which lets a P25 or DMR fleet reach broadband features without a full rip-and-replace. Tait pushed the same idea further with its 9700 series, packing multiple frequency bands and network standards into a single rugged unit.

Another important trend is the growing integration of LMR with broadband networks. Digital radio, LTE, 5G, and Wi-Fi can now work together through multi-network radios and gateways. Instead of replacing an existing radio system all at once, organizations can connect it with newer broadband services. This makes the transition easier and allows users to add wider coverage and data features without giving up existing LMR infrastructure.

Gateways handle the other half of the job. A network-to-network bridge can join an LMR talk group to a PoC talk group, so a dispatcher, a field crew on radios, and a driver on a phone all hear the same call.

One network cleanly replacing the other is the brochure version of this shift. Two networks answering to the same button is what tends to reach the field.

Interoperability is therefore becoming one of the more important parts of the market. Organizations do not necessarily want to throw away equipment that still works. They want a way to connect that equipment to newer broadband tools.

The Features Driving the Switch

A third trend is the growing demand for data-enabled and interoperable communication. Voice is still the core function, but users increasingly want GPS tracking, emergency alerts, messaging, photos, video, and links between different communication networks. This is turning LMR from a voice-only tool into a broader operations platform and is pushing vendors to offer systems that can work with both traditional radio and broadband networks.

Modern PoC platforms tend to bundle

• Live GPS tracking and geofencing for vehicles and lone workers
• Man-down and emergency SOS alerts routed straight to a dispatcher
• Text, photo, and video sharing from the field
• Recorded audit trails for incident review and training

For a logistics manager, that turns a radio into a coordination tool. Routes can be adjusted mid-run. A supervisor can confirm a delivery without placing a call. Voice becomes one channel inside a larger operations picture, and legacy hardware struggles to match that without a stack of bolt-on systems.

This is also where digital LMR systems are changing. Digital radio networks can support more efficient use of available spectrum and provide features that go beyond basic voice. For organizations that need the reliability of LMR but also want modern data capabilities, that combination can make a digital system more attractive than an older analog fleet.

Who Is Buying, and Why

Adoption clusters where teams are mobile, distributed, and safety-sensitive:

• Construction and utilities, with crews spread across sites no single repeater covers
• Transportation and logistics, where drivers leave the property and stay on the network anyway
• Hospitality, retail, and events, where seasonal headcount scales up and down with a subscription
• Security services, where private calls need protection an open analog channel cannot offer

A useful rule of thumb: if your people regularly cross more than one facility or county line, cellular coverage tends to win the argument. If everyone stays inside a single campus with solid in-building radio coverage, the case for switching gets thin fast.

Regionally, North America is expected to account for 35.77% of the global LMR Systems Market in 2026, supported by strong demand for public safety and emergency-ready communication. The U.S. is a major part of this regional market, with continued investment in reliable radio infrastructure alongside newer broadband and push-to-talk technologies.

The U.S. is especially important to this market because of its large public safety, transportation, utility, industrial, and commercial communications base. Agencies and businesses continue to invest in LMR because dependable communication is essential when cellular networks are unavailable or overloaded. At the same time, U.S. organizations are adopting broadband and PoC tools to connect employees across wider areas and to add GPS, messaging, and emergency features.

The country's mature communications infrastructure also supports the move toward hybrid systems. Rather than replacing every radio, many organizations can connect existing LMR networks with LTE and 5G services. This creates a gradual migration path while protecting earlier investments. CMI identifies North America as a major regional market for LMR systems, supported by strong demand from public safety and commercial users.

CMI's LMR market analysis includes companies such as Motorola Solutions, L3Harris Technologies, Thales Group, JVCKENWOOD Corporation, Icom Inc., Hytera Communications, and Tait Communications. These companies compete across areas such as digital radio, public safety communications, broadband integration, network infrastructure, and rugged communication equipment.

How to Run a Pilot Before You Commit

Converting a whole fleet on a vendor's promise creates a cascade of problems. A staged test gives you a baseline for comparison.

1. Map your dead zones first. Walk every site with a PoC device and a legacy radio side by side, and record where each one fails.
2. Pilot one team rather than one department. Ten to fifteen users over two months will surface most of the complaints.
3. Test the ugly days. Shift changes, storms, and packed events tell you more than a quiet Tuesday ever will.
4. Price the full lifecycle. Put subscription totals next to licensing, repairs, and infrastructure you would otherwise carry yourself.
5. Keep an interoperability bridge in place. Gateways can link LMR and PoC talk groups so both systems stay connected during the transition.

The Button Stays, the Network Underneath It Changes

The uncomfortable truth is that most organizations will run both for years. Two-way radios remain the safer answer in tunnels, mines, and disaster zones where public networks buckle. Push-to-talk over cellular has taken over the wide-area, data-rich, subscription-friendly middle of the market, and that middle keeps expanding.

The growth of the LMR market does not change that picture. In fact, the LMR Systems Market is expected to more than double by 2033, showing that demand for dependable radio communication remains strong even as broadband technologies gain ground.

Buyers who treat this as an either/or decision tend to get blindsided by the one exception they never tested for. Buyers who map coverage, price the full lifecycle, and run a hybrid through the transition can move at a pace their teams absorb without drama.

The market is moving toward a mix of private radio, broadband networks, and connected devices rather than one technology replacing everything else. The button may still feel the same to the person holding the handset. What changes is everything underneath it.

If your radio contract comes up for renewal soon, ask yourself: what would change if the next fleet you bought was chosen on coverage data instead of habit?
