The technology

Radio coverage without the radio network

Push-to-talk over cellular puts your talkgroups on the 4G network instead of on repeaters you have to build, licence and maintain.

Press the button and you are talking — to one person, a talkgroup, or everyone — anywhere the cellular network reaches. That is most of the country on day one, with no site acquisition, no spectrum licence, no repeater maintenance and no coverage survey.

It behaves like a radio because it is a radio. Instant push-to-talk, no dialling, no ringing, no call to answer. What changes is what sits behind it: a national carrier network instead of a hilltop, and a dispatch console instead of a base station.

  • National coverage from day one. Anywhere 4G reaches, which for most fleets means the whole operating area rather than a licensed cell around a repeater.
  • No infrastructure to own. No sites, no towers, no repeater servicing, no licence renewals, no coverage gaps to engineer around.
  • Your choice of carrier. We run on Spark or One NZ — the two best networks in the country — so you pick whichever covers your sites and routes best.
  • Both networks on one device. Dual-SIM models take a Spark and a One NZ SIM together. You choose the active one in the device settings, the same way a dual-SIM phone works, so a crew heading into a known weak spot can switch rather than lose contact.
  • Unlimited talkgroups. Restructure teams, depots and shifts from the console — not by reprogramming every radio in the fleet.
  • GPS on every device. Location reporting and track history come as standard, not as a separate telematics purchase.
  • Scales by one. Add a device or a user without touching anything else.

An honest comparison

PoC or DMR?

We sell both, so here is the straight answer rather than the sales one. PoC wins for most commercial fleets. DMR still wins in specific places, and we will tell you when yours is one of them.

PoC DMR / analogue
Coverage National, wherever 4G reaches Limited to your repeater footprint
Up-front cost Devices only Devices, repeaters, sites, antennas, licensing
Ongoing cost $17 per device, per month Licence fees, site rental and repeater maintenance
Time to deploy Days Weeks to months
Works with no network No — it needs cellular or Wi-Fi Yes, including direct radio-to-radio
Deep in-building and underground Depends on cellular coverage Engineered to suit the site
Dispatch, GPS and recording Included Added at extra cost
Adding a site or region Nothing to build New infrastructure

Where DMR still wins: underground work, tunnels, remote back-country sites with no cellular coverage, and any operation that must keep talking when the public network goes down. If that is you, we will quote you DMR — or a hybrid, with the Smart Gateway bridging your DMR fleet into the same talkgroups as your PoC devices.

Our customers’ favourite part

PoC web dispatcher

Buyers compare radios. Then they use the system for a month and realise the console is what actually changed how they run the operation. It runs in a browser, there is nothing to install, and no hardware to invest in.

See

Live map and track playback

Every device's GPS position on one map in real time, with recorded tracks you can replay — where a vehicle went, when it stopped, how long it was there.

Talk

Every call type from the desk

Individual, group, all-call and broadcast, initiated by the dispatcher. Reorganise talkgroups on the fly without touching a single device.

Protect

SOS and lone worker

Emergency alerts land on the console with the caller's location. Lone-worker monitoring and man-down detection escalate automatically when someone cannot press a button themselves.

Prove

Voice recording

Calls are recorded and held for three months, and you can download anything you need to keep for longer straight from the platform. An incident review becomes a search rather than an argument about who said what.

Patrol

Patrol management

Patrol points, routes, plans and events, with reports and statistics out the other end. Guards tag checkpoints by NFC; you get evidence the round was walked.

Assign

Job ticketing

Issue a job to a device, track its state, close it off. The work and the conversation about the work stay in one place.

Watch

Real-time video

Live video from body cameras, PoC smartphones and in-cab terminals straight to the console, so a supervisor can see the situation instead of hearing a description of it.

Bridge

DMR and PDT interconnect

The Smart Gateway links existing DMR or PDT radio networks into the same talkgroups, so a staged migration does not mean two disconnected fleets.

Web dispatch console Any browser PTToC platform over 4G Nationwide Handhelds In-vehicle Body cameras App users Smart Gateway Existing DMR / PDT fleet
One console, one set of talkgroups — including radios you already own.

Who runs it

3,500 devices, in real fleets

Transport operators, waste fleets, security teams and national organisations run day-to-day operations on the network we built.

“I've had only great experiences working with Elisha and the team at Signals. They are knowledgeable, responsive, and clear in their communication, making the entire process seamless.”

Deon LotzAptitude Security

“Elisha and Signals NZ were extremely helpful in assisting with the selection and implementation of a [PoC] system for our construction site, all at a competitive price.”

Not everyone needs a radio. The Press2Talk app puts the same talkgroups on a staff member’s own phone for $17 per user per month plus GST — useful for managers, back office and anyone who only occasionally needs the channel.

Try it first

Scope your free trial

We do not hand out a box and hope. We scope the trial around how your people actually work, configure it, and put real devices in real hands on your own sites.

Tell us how you operate

Sites, routes, shift patterns, who needs to talk to whom, and what your current radios do badly. Twenty minutes on the phone covers it.

We configure it

Talkgroups, dispatch console, SIMs, user accounts and any safety features set up to match your structure before the devices leave us.

Run it on your own site

Handhelds from our demo fleet go out quickly. In-vehicle units take a little more arranging, but we do those too. Use them properly, then decide.

Start the conversation

Tell us the basics and we will come back to you to scope it properly. If you would rather talk it through, call 0800 454 756.

Trials are scoped individually because configuration is most of the value. Handheld demo units are readily available; in-vehicle units are limited in number but can usually be arranged.

Straight answers

Questions we get asked

What happens when a device goes out of cellular coverage?

It stops transmitting until coverage returns, and the console shows it as offline. This is the honest limitation of PoC and the main reason we still sell DMR. Three things reduce it in practice. You choose whether to run on Spark or One NZ, so we start with whichever network actually covers your sites. Dual-SIM devices take one of each, and the active SIM is chosen in the device settings the same way it is on a dual-SIM phone — it is not an automatic handover, but a crew working a known weak spot can switch before they get there. And the devices work over Wi-Fi, which covers most in-building dead spots. If your operation genuinely runs beyond cellular coverage, tell us early and we will quote you differently.

Can it talk to the DMR radios we already own?

Yes. The Smart Gateway bridges DMR and PDT networks into the same talkgroups as your PoC devices, so a migration can be staged over months rather than done in one weekend. A lot of our customers ran both for a period before the old fleet came out of service.

What does it actually cost to run?

The device, then $17 per device per month, which covers the network service, the web dispatcher, call recording and GPS. That is the cheapest PoC network in New Zealand, and significantly cheaper to run than most regional or national repeater networks, because there is no repeater to build, no site rental, no spectrum licence and no coverage engineering. We publish device pricing on our product pages — most of our competitors do not.

Which cellular network does it run on?

Spark or One NZ — the two best networks in the country — and the choice is yours. We look at your sites and routes and recommend whichever covers them better. On dual-SIM devices you can carry both and select the active SIM in the settings, so a crew can switch networks in the field when they need to.

Do we need a radio licence?

No. PoC runs on the cellular network, so there is no spectrum licence, no frequency coordination and no renewal to diarise.

How long does deployment take?

Days rather than months. The devices arrive configured with your talkgroups and user accounts already set up, so deployment is handing them out and a short briefing. There is no infrastructure to install.

Can we restructure talkgroups later?

Yes, from the console, without collecting the radios. This is one of the larger practical differences from DMR, where changing the fleet plan means reprogramming every handset.

What happens to the recordings and location data?

Calls are recorded and held for three months on the platform, and you can download anything you need to keep for longer through the web dispatcher and store it yourself. GPS tracks are kept for playback over the same period. If you have a retention policy of your own, tell us and we will set the trial up to match it.

Why Kirisun?

We are the exclusive New Zealand distributor, which means stock in the country, parts and accessories on the shelf, firmware and platform support direct from the manufacturer, and a range that runs from a screenless handheld to a body camera on one service. It also means the people supporting the devices are the people who imported them.
