Signal & Steel OpenMANET HaLow Mesh Radio – Off-Grid Private Communications Node (915MHz Long-Range, Pre-Flashed)

Signal & Steel OpenMANET Radio – Private, Off-Grid Communications

The Signal & Steel OpenMANET Radio is a long-range, infrastructure-free communications device built for privacy, resilience, and off-grid operation. Using Wi-Fi HaLow (802.11ah) in the 915 MHz band and professionally loaded with OpenMANET firmware, this unit lets you build your own independent mesh network without relying on cellular carriers, ISPs, or centralized systems.

Power it on and it automatically joins or forms a self-healing mesh network, allowing connected devices to communicate across nodes over long distances and through challenging environments.

Why It Exists

Modern communications often depend on outside infrastructure that can be monitored, restricted, degraded, or simply unavailable.

The Signal & Steel OpenMANET Radio offers an alternative: a locally controlled, peer-to-peer network that keeps working even when outside connectivity does not.

No accounts. No subscriptions. No cloud dependency.

Core Capabilities

Private Mesh Networking

• Devices communicate over a locally controlled 10.41.0.0/16 network

• No reliance on external infrastructure

• Supports local services, messaging, and standard IP-based tools

Long-Range, Low-Frequency Operation

• 915 MHz Wi-Fi HaLow (802.11ah) for extended range

• Better penetration through buildings, foliage, and terrain than traditional Wi-Fi

• External antenna support for optimized deployment

Self-Healing, Multi-Hop Network

• Powered by BATMAN-V mesh routing

• Nodes automatically discover one another and route traffic dynamically

• Coverage expands by simply adding more units

Local Access for Your Devices

• Built-in 2.4 GHz Wi-Fi access point

• Ethernet connectivity for wired devices

• Automatic IP assignment via DHCP

Optional Internet Gateway

• One node can be designated as a gateway for upstream internet access

• Keeps your mesh network logically separate from the outside network
