Atlanta / Southeast

Atlanta / Southeast

Geographic Context

Atlanta sits in the Georgia Piedmont at approximately 1,050 ft above sea level - an elevation that already provides a propagation advantage over the Coastal Plain to the south and east. Two prominent landmarks bookend the metro: Stone Mountain (1,686 ft) to the east and Kennesaw Mountain (1,808 ft) to the northwest. Further north, the Georgia Blue Ridge - part of the southern Appalachians - rises to 4,000+ ft and provides dramatic line-of-sight opportunities for long-range relay nodes.

Network Status

A growing Meshtastic community anchored by ham radio clubs and emergency preparedness groups across metro Atlanta and north Georgia. Active deployments in the Atlanta urban core are expanding outward into suburban counties and increasingly into the north Georgia mountain communities along and near the Appalachian Trail.

Recommended Preset

Long Fast is the standard preset for most of Georgia and the broader Southeast. The relatively lower node density compared to Northeast urban corridors means Long Fast does not generate the collision and congestion issues seen in markets like NYC. As the Atlanta metro node count grows, watch the local Discord for any community decisions to migrate denser areas to Medium Slow.

Notable Infrastructure

• Stone Mountain State Park summit - at 1,686 ft with a bald granite dome, summit nodes provide outstanding coverage across the eastern Atlanta metro. Coordinate with the park on any permanent installation.
• Kennesaw Mountain National Battlefield Park - at 1,808 ft, provides excellent north Atlanta coverage. NPS sites have specific rules for radio installations; verify requirements with the park before deploying any permanent infrastructure.
• Amateur radio repeater infrastructure (VHF/UHF) on towers throughout the metro provides potential co-location opportunities for mesh nodes - reach out to tower owners through ham radio clubs.

Appalachian Trail Corridor

The AT enters Georgia at Springer Mountain and runs northeast through some of the most scenic terrain in the Southern Appalachians. Proximity to Atlanta means a large hiker community, and mesh nodes catering to backcountry users are increasingly deployed along this corridor. Hikers use Meshtastic for group tracking, position sharing, and off-grid messaging on multi-day treks. Note that permanent infrastructure in wilderness and national forest areas requires appropriate permits.

Hurricane & Severe Weather Preparedness

The Southeast faces a wide range of severe weather threats: Atlantic and Gulf Coast hurricanes (and their inland remnants), tornadoes, and severe ice storms that can knock out power for days. ARES chapters across Georgia, Alabama, Tennessee, and the Carolinas are actively incorporating LoRa mesh into EmComm exercises as a complement to traditional HF and VHF infrastructure. Post-landfall hurricane scenarios, where cellular and internet infrastructure may be compromised across a wide area, are a primary driver of this interest.

Community

• Atlanta ARES - active EmComm exercises incorporating mesh nodes.
• Georgia Tech Amateur Radio Club (W4AQL) - university-based club with active technical experimentation in mesh networking.
• Regional Meshtastic Discord groups covering metro Atlanta, north Georgia mountains, and broader Southeast.
• Connections to neighboring state ARES sections (Alabama, Tennessee, South Carolina, North Carolina) for regional EmComm coordination.
