CB radio vs LoRa mesh
CB radio is established and simple. LoRa mesh is modern and capable. Which technology best serves your emergency communication needs?
Two approaches to off-grid communication
CB radio (Citizens Band) dates from the 1950s and remains popular with truckers, farmers, and preparedness enthusiasts. It is simple, affordable, and requires no licence. But does this established technology still represent the optimal choice?
LoRa mesh networking (via MeshCore) represents contemporary emergency communication. It combines extended range with intelligent routing, privacy features, text messaging, and exceptional power efficiency. Is this the future of personal emergency radio?
Understanding CB radio
CB radio (Citizens Band) provides licence-free two-way voice communication with 40 available channels. Anyone within range on the same channel can participate. Popular with lorry drivers, rural communities, and outdoor enthusiasts.
CB radio strengths
- ✓
Simplicity: Power on and start talking immediately
- ✓
Cost: Entry-level equipment from £50-150
- ✓
Voice: Real-time voice conversation
CB radio limitations
- ✗
Range: Typically 5-10km maximum in practice
- ✗
Privacy: Anyone can listen to any channel
- ✗
Portability: Equipment tends to be larger and heavier
Understanding LoRa mesh
LoRa (Long Range) is modern radio technology organised into a mesh network. Devices communicate both directly and via repeaters. Messages automatically hop through the network to reach their destination.
LoRa mesh strengths
- ✓
Extended range: ~1-10km direct, extended indefinitely via mesh
- ✓
Privacy: End-to-end encryption for private messages
- ✓
Versatility: Text messages, location sharing, data transfer
- ✓
Efficiency: Battery life measured in days to weeks
Direct comparison
| Feature | CB Radio | LoRa Mesh (MeshCore) |
|---|---|---|
| Communication type | Voice only | Text, data, location |
| Range | 5-10km direct | 1-10km + unlimited via mesh |
| Privacy | None (open channel) | Full (end-to-end encrypted) |
| Message storage | No | Yes (delivered when in range) |
| Battery life | 8-24 hours | Days to weeks |
| Size | Larger, heavier | Compact, pocket-sized |
Where LoRa mesh exceeds CB radio
Mesh networking
Messages hop via repeaters until reaching their destination. CB requires direct range. LoRa mesh is fundamentally more flexible.
Genuine privacy
CB: anyone within range can listen. LoRa: private messages are encrypted and unreadable by others.
Text capability
CB handles voice only. LoRa offers text, location sharing, and small data transfers. Far more versatile.
Modern interface
LoRa connects to your smartphone. CB requires a dedicated handset. More intuitive for most users.
Power efficiency
LoRa is remarkably efficient. CB equipment lasts perhaps 24 hours; LoRa devices last weeks.
Intelligent routing
LoRa mesh automatically finds optimal paths. CB is simple broadcasting without any intelligence.
Common questions
Is CB radio not more reliable because it is simpler?
Simpler, yes. More reliable, not necessarily. LoRa is equally reliable technology with far greater capability. Proven in demanding applications worldwide.
Can LoRa handle voice communication?
LoRa is primarily text and data. For voice, CB remains better suited. Some users combine both: CB for voice, LoRa for text, location, and coordination.
How do costs compare?
CB: £50-150 for a reasonable setup. LoRa: £50-80 per device. Similar pricing, but LoRa offers substantially more functionality. See the hardware options.
Which is better for serious preparedness?
LoRa is more modern and future-proof. The growing mesh network across Britain becomes stronger continuously. CB remains static. For comprehensive preparedness: having both provides options.
Is LoRa harder to use than CB?
Initial setup involves Bluetooth pairing. After that, messaging is as intuitive as any chat application. CB is plug-and-talk but offers less capability.
Choose modern technology
CB radio is proven but established technology. LoRa mesh networking offers modern capabilities for off-grid communication. LocalMesh is a community project. Coverage depends on volunteer participation and varies by location. Not a replacement for emergency services – always dial 999 in emergencies.
