Before you ask for quotes, it helps to know what to compare. A PoC radio (push-to-talk over cellular) runs on a carrier’s SIM and 4G network, so the choice involves questions a regular two-way radio never raises: carrier bands, platform and equipment authorization. If you are new to the idea, start with PoC radio: what it is and how it works.
1. Device type
The right form factor depends on who uses it and where:
- Handheld PoC radio: looks like a walkie-talkie, with a big PTT button, a loud speaker and a small screen or none. Good for people who only need to talk.
- Rugged phone with PTT: a tough smartphone with a dedicated PTT key, for crews that also use work apps, the camera and maps.
- Vehicle terminal: installed in a truck, bus or patrol car and powered by the vehicle.
- Body camera: records video and also does PTT, for security and enforcement.
- Dispatch console: the desk of whoever coordinates the team.
2. Ruggedness: IP, MIL-STD and hazardous locations
- IP rating (IEC 60529): the first digit is dust, the second is water. IP67 is dust-tight and survives immersion up to 1 meter for up to 30 minutes. For IP68 the manufacturer sets the depth and time, so check what it declares.
- MIL-STD-810: a US military standard of test methods (drop, vibration, temperature), not a single seal. Each product is tested only to the methods and limits chosen for it. Ask which tests were run.
- Hazardous locations: in refineries, fuel depots, mines and chemical plants, where flammable gas or dust may be present, OSHA requires equipment that is intrinsically safe or approved for the location’s class and substances (29 CFR 1910.307). ATEX marking is the European Union’s equivalent; for a US site, ask for the Class/Division approval your safety team requires.
In the device list you can filter by minimum IP rating and by ATEX.
3. Network and LTE bands
A device only works well if it supports the LTE bands your carrier uses where the crew works. A band reference updated in February 2026 lists these LTE bands for the three national carriers:
| Carrier | LTE bands |
|---|---|
| AT&T | 2, 4, 5, 12, 14, 17, 30, 46, 66 |
| Verizon | 2, 4, 5, 13, 46, 48, 66 |
| T-Mobile | 2, 4, 5, 12, 25, 26, 41, 46, 66, 71 |
Band 14 is the public-safety spectrum provided by the FirstNet Authority and built out by AT&T. According to FirstNet, it covers larger areas with less infrastructure and gets through walls better than higher bands; FirstNet subscribers come first, and other AT&T customers use it when it is free. If your team needs FirstNet, the device must support Band 14.
Imported PoC radios sometimes ship with another market’s bands. Check the “LTE bands” field on each device page and ask the carrier which bands it runs in your area. Dual SIM helps when no single carrier covers everything.
4. PoC platform: open or locked device
A PoC radio needs a platform that carries the voice between devices. There are two kinds of device:
- Open: usually Android, it can run apps from several platforms. If you change providers, the hardware still works.
- Locked: tied to one platform. Setup can be simpler, but switching platforms may mean replacing the radios.
Each device page lists the platforms the manufacturer mentions. Ask the seller whether the unit is locked and whether the platform includes dispatch, GPS and recording. What each part costs is covered in How much a PoC radio costs.
5. FCC authorization
Under 47 CFR 2.803, no one may market a radio frequency device unless it is authorized by the FCC. Every PoC radio has a cellular modem, so it needs an FCC ID. Before buying, look up the model in the list of PoC devices certified in the United States, which shows the FCC ID and a link to the public record.
6. Battery and accessories
Compare battery capacity (mAh) on the device pages, but remember that the screen, GPS and Android also draw power. Ask whether the battery is removable, whether spares exist and whether there is a multi-unit charger for the fleet. For accessories, check for a remote speaker microphone (the shoulder mic), a PTT earpiece and a belt clip, and whether the connector is standard or brand-specific. In noisy places, speaker output matters.
7. MCPTT, if the job is mission critical
MCPTT is the 3GPP standard for mission-critical push-to-talk over LTE, with targets such as access time under 300 ms, network priority and direct device-to-device calls. Ordinary commercial use does fine with regular PoC. Public safety and critical operations often require MCPTT. See the devices with MCPTT.
8. Where to buy and who supports it
Buy from a seller that offers an authorized device, a local warranty and help setting up the platform. See resellers in where to buy.
Checklist
- Does the device type fit the crew’s work?
- Do the IP rating and MIL-STD tests match the environment? Is a hazardous-location approval needed?
- Does the device support your carrier’s bands (Band 14 for FirstNet), and is there coverage where the crew works?
- Is the device open or locked to one platform?
- Does it have an FCC ID?
- Are batteries and accessories (shoulder mic, earpiece) available?
- Does the operation require MCPTT?
- Does the seller offer a warranty and support?
