## Mesh and Amateur Radio (ARES/RACES)

LoRa mesh and traditional amateur radio serve complementary roles in emergency communications. Understanding how they fit together helps you deploy each where it is most effective.

### What ARES and RACES Are

**ARES (Amateur Radio Emergency Service)** is an ARRL program where licensed amateur radio operators provide emergency communications for served agencies (Red Cross, hospitals, government agencies). **RACES (Radio Amateur Civil Emergency Service)** is a similar program with formal government ties, activated during civil emergencies.

Both programs have established protocols, training requirements, and communication plans. They operate on licensed amateur radio frequencies with trained operators.

### Where Mesh Fits In

### Practical Integration Model

A realistic combined deployment:

- **Neighborhood layer (LoRa mesh):** Blocks to several miles - coordination among neighbors, location sharing, welfare checks. No license required; any resident can deploy a node.
- **Regional layer (VHF/UHF amateur):** Repeater-linked coverage across a county or metro area. Requires licensed operators; handles voice coordination between neighborhoods and EOC.
- **State/national layer (HF amateur):** Winlink gateways and HF nets for long-distance traffic when regional infrastructure is compromised.

### For Amateur Radio Operators

If you hold an amateur radio license, consider:

- Deploying LoRa mesh alongside your existing radio setup to provide text/data capability for neighbors who don't have radio licenses
- Using LoRa mesh for neighborhood coordination while using your radio for ARES/RACES served agency traffic
- Advocating for LoRa mesh within your ARES group as a force multiplier for neighborhood-level coverage
