🛰️ Network Infrastructure Overview
The deployment of two specialized nodes within the US/PA mesh segment. The architecture utilizes a “Remote Admin” model where the mobile field node (MW2) maintains control over the fixed gateway (MW1).
📟 Node: MW1 (The Gateway)
The Heltec V3 acts as the mesh-to-internet bridge. It is managed remotely to minimize the need for physical access to the gateway location.
🛠️ Hardware Specifications
- Long Name: MW1 | Short Name: MW1
- Processor: ESP32-S3
- Antenna: Gizont 915MHz 17cm Whip
- Enclosure: Alley Cat 3D-Printed (Black)
- Role: Client / MQTT Bridge
🔌 Power & Connectivity
- Primary Power: USB-C / MakerFocus 800 mAh LiPo
- Wi-Fi: Enabled
- MQTT Root:
msh/US/PA
🌲 Node: MW2 (The Controller)
The Heltec T114 is the primary mobile unit. Due to its superior battery life and the nRF52 architecture, it serves as the secure administrative terminal for the network.
🛠️ Hardware Specifications

- GPS: Integrated (Active) 📍
- Antenna: Meshtastic Long Range 915MHz (3dBi Gain Omni)
- Enclosure: Heltec T114 Slim Pro (Dark Green)
- Role: Client / Admin
🔌 Power & Connectivity
- Primary Power: MakerFocus 3000 mAh LiPo Battery
- Wi-Fi: None
- MQTT: Off
🔐 Inverted Administration & Governance
In this configuration, MW2 has been granted explicit administrative permissions over MW1. This allows the operator of MW2 to change channels, update positions, or reboot MW1 over the LoRa mesh.
| Controller Node | Managed Node | Permission Level |
|---|---|---|
| MW2 (T114) | MW1 (V3) | Master Admin |
📐 RF Performance & Propagation
The network leverages two distinct antenna profiles:
- MW1 (Gizont Whip): Optimized for broad, omnidirectional coverage in semi-urban environments.
- MW2 (3dBi Omni): Increased gain to ensure that administrative commands reach the MW1 gateway even from the edge of the mesh range.
