Pick a walkie talkie (FRS, GMRS or PMR446) when you need instant voice over a few hundred metres to a few kilometres, such as on a job site or a ski slope. Pick Meshtastic when text, shared GPS positions and relaying across many hops matter more than speaking. Pick ham radio if you want voice over long distances and are willing to study for a licence. Meshtastic itself needs no licence on its licence-free bands.
These tools overlap less than their names suggest. Meshtastic moves tiny packets slowly on a licence-free band. Walkie talkies move live voice on dedicated bands, each with their own legal rules.
| Meshtastic | FRS (US) | GMRS (US) | PMR446 (Europe) | Ham radio | |
|---|---|---|---|---|---|
| Carries | Text, positions, telemetry | Voice | Voice, short text on handhelds | Voice | Voice, data, many modes |
| Licence | None (US Part 15.247; EU SRD rules) | None | Individual licence, 18 or older | None | Licence by exam |
| Power | US: up to 30 dBm (1 W) conducted; EU: 500 mW ERP, 10% duty cycle on 869.4-869.65 MHz | 2 W on some channels, 0.5 W on others (see below) | Handheld up to 5 W ERP on 462 interstitials | 500 mW ERP | Depends on licence class |
| Antenna | Can be changed (mind ERP) | Fixed on handhelds | Can be changed | Integral only | Free choice |
| Relays | Phones and nodes forward text | None | Repeaters allowed | No repeaters | Repeaters common |
Licences and power limits
Meshtastic. In the US it relies on 47 CFR 15.247: 902-928 MHz, up to 1 W peak conducted output, with no duty cycle limit in the rule. In Germany the Bundesnetzagentur allows 500 mW ERP on 869.4-869.65 MHz with a duty cycle up to 10%. Details and other countries: is Meshtastic legal and frequencies by country.
GMRS. The FCC requires an individual licence to operate a GMRS station, and applicants must be at least 18 (47 CFR 95.1705). The licensee can let immediate family members use the station. For power, 47 CFR 95.1767 caps handhelds at 0.5 W ERP on the 467 MHz interstitial channels and 5 W ERP on the 462 MHz interstitial channels. Main channels are limited by output power, up to 50 W for mobile, repeater and base stations. GMRS has 30 channels, 16 main and 14 interstitial, per 95.1763.
FRS. Per the Wikipedia summary of the FCC rules (check the current Part 95 text before relying on it), FRS radios are licence-free, handhelds must keep permanently attached antennas, and since 2017 channels 1-7 and 15-22 allow 2 W while channels 8-14 stay at 0.5 W. Operating over those limits or on repeater inputs needs a GMRS licence.
PMR446. The 446.0-446.2 MHz band is licence-free across CEPT countries. Analogue PMR446 radios are limited to 500 mW ERP, must use an integral antenna and cannot be base stations or repeaters (source: Wikipedia's summary of the CEPT rules; the regulator text was not available when this page was checked). Digital modes (dPMR, DMR Tier I) use the same band.
Ham radio. The FCC states a station must be under the control of a person named in an amateur station licence before it transmits (47 CFR 97.5). Amateur rules forbid obscuring the meaning of messages, so encryption is out. Meshtastic's licensed mode sends everything unencrypted; see channels and encryption.
Range
Walkie talkies on FRS or PMR446 are line-of-sight tools. Wikipedia quotes about 0.5 to 1.5 km for FRS in normal conditions and says that in a city PMR446 users can expect a few hundred metres or less. Meshtastic uses LoRa, a slow modulation built for weak signals, and relaying adds distance. The range guide has measured records; the range calculator lets you test your own heights.
Ham radio on VHF and HF can go much farther, but only if you hold a licence and have the equipment.
What you give up
- Voice. Meshtastic cannot do a call. Messages stay on air for a noticeable time, longer on slower presets (see presets), and the app shows delivery state.
- Speed. A walkie talkie answers instantly. A Meshtastic message may wait for acknowledgement and retries.
- Phone needed. Most Meshtastic nodes are used through a phone app, or a device with a keyboard.
What you gain
- Group and private channels with encryption on licence-free bands.
- Positions on a map for everyone in the group.
- Relaying through other nodes without a repeater licence.
- Battery: a small nRF52 node runs for days; see the battery calculator.
Which one should you pick?
- Walkie talkie (FRS or PMR446): crews, kids, events, ski areas. Instant voice with no setup and no licence.
- GMRS: US families who want more power and repeaters and accept the licence.
- Meshtastic: hiking, backcountry, group trips, emergency kits. Text and positions at long range with a tiny device.
- Ham radio: serious long distance voice and experiments, if you pass the exam.
- Both: many people carry a walkie talkie for voice and a Meshtastic node for text and tracking.
Questions people ask
Is Meshtastic better than a walkie talkie?
It depends on the job. It beats a walkie talkie for text, location sharing and multi-hop reach. It loses for voice and instant replies.
Do I need a licence to use Meshtastic?
Not on the standard licence-free bands in the US or EU, as long as you stay within the power and duty cycle rules for your region. Using amateur bands or licensed mode needs a ham licence.
Do I need a GMRS licence for FRS radios?
No, FRS is licence-free. A GMRS licence is required to operate a GMRS station under 47 CFR 95.1705.
Can Meshtastic send voice?
No. Meshtastic carries short text, positions and telemetry. The data rates of its presets are too low for voice.
