Learning Resources¶
MeshCore & LoRa Basics¶
- What is LoRa? — The Things Network LoRa overview — explains the underlying radio technology in accessible terms
- Spread Spectrum explained — good background on why LoRa achieves such long range at low power
Radio & Antenna Fundamentals¶
Understanding a few basic antenna concepts will help you get the most out of your node placement:
- dBi and gain — higher gain antennas focus energy in a particular direction
- Line of sight — LoRa is primarily line-of-sight; elevation is your best friend
- Fresnel zones — why trees and buildings at distance matter more than you might expect
FCC Part 15 Rules¶
The 915 MHz ISM band is governed by FCC Part 15, which allows unlicensed operation within power limits. Key points for MeshCore users:
- Maximum conducted power: +30 dBm (1 Watt)
- Maximum EIRP (with antenna gain): +36 dBm (4 Watts)
- No license required for operation within these limits
- Must accept interference from other Part 15 devices and cannot cause harmful interference
Amateur Radio in the CSRA¶
MeshCore is popular in the ham radio community and complements traditional voice repeater networks. You don't need a license to use MeshCore (it operates under Part 15), but many CSRA MeshCore users are licensed amateurs.
Local ham resources:
- CSRA Amateur Radio Community — search for local clubs in Augusta and Aiken
- ARRL — arrl.org — national amateur radio organization, license info and study materials
- HamStudy — hamstudy.org — free Technician license exam prep
A Technician license opens up additional VHF/UHF digital modes that pair well with MeshCore for wider-area coordination.
