Maintenance hears the call at the back of the plant.
Between machines and concrete walls, the audio arrives clean. The repeater was positioned after measuring the signal on site.
Radios and field teams
Your Team Talking, Near or Far.
One button, and everyone hears. In the building, in the yard or in another city, the team talks instantly, without dialing and without waiting for someone to see a message.
In a few words
A professional radio is the way to talk to the whole team by pressing a button. Digital radio covers the building, the yard or the plant with its own signal. Radio over the cellular network talks between cities. ARX measures the coverage on site, recommends the right type, guides you on the Anatel (Brazil's telecom regulator) license and installs.

In your day
You use it every day and almost never notice.
When the radio works, the team does not even notice. Press, talk, solve. You only notice the radio on the day someone calls and nobody answers.
Housekeeping says the room is ready.
One press on the compact radio and the front desk already knows. The guest who arrived early goes up without waiting.
The base talks to the driver in another city.
The truck's radio uses the cellular network. The base sees on the map where each vehicle is and calls only that group.
The patrol records what it saw.
The camera on the uniform records the encounter. If there is a complaint the next day, there is footage with date and time.
When it fails
That's when everyone notices.
The three problems we find most often, where they come from and how we avoid them.
The radio does not work in the basement.
Where it comes fromThe radios were bought for the range printed on the box. Nobody walked through the building measuring where the signal disappears: garage, stairwell, machine room.
How ARX avoids itWe test the coverage on site before closing the project. Where the signal does not reach, a repeater or another technology comes in, and you see the test result.
The audit rejected the radios in the hazardous area.
Where it comes fromWhere there is gas, fuel or flammable dust, ordinary equipment cannot be used. In Brazil, the radio needs its own certification for this environment.
How ARX avoids itWe ask about hazardous areas right at the start. For them, we recommend only models with a certificate valid in Brazil, and we check the document before proposing.
The cellular radio went silent in the warehouse.
Where it comes fromThis type of radio depends on the carrier's signal. Where the cell phone does not work, it does not talk either. Many people find this out after buying.
How ARX avoids itWe measure the carriers' signal at the points where the team works. If there is a gap, we combine on-site digital radio with the cellular network for distance.
How ARX does it
Simple for you. Rigorous on the inside.
We ask where the team works
Building, basement, yard, road, another city. How many groups need to talk to each other and whether there is an area with gas, fuel or flammable dust.
You receive: the map of where the team needs to talk.
We measure coverage on site
We walk through the critical points with test radios. It is the measurement, not the catalog, that decides between digital radio, cellular network or both.
You receive: the test result and the recommended technology.
We handle what is mandatory
Equipment approved by Anatel. When the project uses its own frequency, we guide you on the authorization and the license. In hazardous areas, only certified models.
You receive: the equipment list with the approvals.
We program, deliver and train
Groups, channels and emergency call configured according to the routine. The team learns to use it, and the usage rules are put in writing, including for body cameras.
You receive: the radios programmed and the usage rules.
Equipment
What goes into your project.
Examples of what we install. The final choice depends on your space and your budget.
Communication at the push of a button inside the building, yard or plant, without depending on a carrier.
Light and direct, for store, hotel, residential building and event teams.
Built for environments with gas, fuel or flammable dust.
Same button, city-wide or nationwide reach, using the carriers' network.
Handheld and vehicle models that talk between cities and appear on the operations center map.
Brands
The right brand is the one that fits your project and your budget.
HyteraWhen the team works in a defined place and needs its own signal, including in hazardous areas.
InricoWhen the team spreads across neighborhoods and cities and the base needs to see each person on the map.
AxisWhen the body camera needs to join the same video system that already records the site's cameras.
HikvisionWhen vehicles need an onboard camera, with a recorder built to withstand vibration and the road.
What hardly anyone tells you
Before asking for a quote, it's worth knowing.
Its own frequency requires Anatel authorization.
A professional radio with its own frequency needs authorization for use and a license for the stations. Operating without them can result in fines and seizure. Low-power radios and radios over the cellular network follow other rules. Ask who takes care of this.
Range printed on the box does not exist.
The number printed on the box applies to open field. Concrete, basements, metal structures and machinery change everything. That is why we do not state a range before measuring at your address.
A camera on the team needs a rule before it is turned on.
Who uses it, when it records, who can view it and how long the footage is kept. This applies to the uniform camera and to the vehicle camera. Without this in writing and communicated, it becomes a source of conflict instead of protection.
Questions and answers
What is the difference between a digital radio and a radio over the cellular network?
Digital radio uses its own signal: it works inside the building, the yard or the plant, without depending on a carrier. Radio over the cellular network uses the carriers' signal: it talks between cities, but only where there is coverage. Many operations use both together.
Do I need an Anatel license to use a radio?
It depends on the type. A radio with its own frequency needs authorization for use and a license from Anatel. Low-power, free-use radios and radios over the cellular network do not go through this process. In all cases, the device must be approved.
Why not use WhatsApp instead of a radio?
Because a message waits for someone to look at it. On the radio, you press a button and the whole group hears right away, even with busy hands or gloves on. In an emergency, that difference is what counts.
Does radio work in basements and metal warehouses?
It works when the project accounts for it. Basements, stairwells and warehouses with metal structures usually have dead spots. That is why we measure first. Where needed, a repeater carries the signal there. Without measuring, the honest answer is: I don't know.
I already have old radios. Do I need to replace them all?
Not always. We assess the devices, the batteries and the license you already have. In many cases, you can keep some of the radios and replace them in stages, with new and old working together during the transition. It depends on the models.
Does ARX serve teams in any city?
Installation, with an on-site team, is done in the State of São Paulo: the capital, the interior and the coast. Design, consulting and retrofit design, on the other hand, serve all of Brazil.
