M7 Industrial Radio Modem (VHF & UHF)
Rugged ½–5W wireless data modem engineered for long-range SCADA, telemetry, and industrial communication—available in both VHF and UHF bands for maximum deployment flexibility.
M7 RADIO MODEM
OVERVIEW
The M7 radio modem is a proven long-range wireless communication solution built for demanding industrial environments. Supporting both VHF (150–174 MHz) and UHF (450–470 MHz) operation, it enables reliable deployment across varied terrain and RF conditions.
Designed for performance and flexibility, the M7 delivers fast polling speeds, configurable data rates, and store-and-forward repeating—making it ideal for SCADA systems, telemetry networks, and distributed infrastructure.
CORE CAPABILITIES
FREQUENCY OPTIONS
UHF Configuration (450–470 MHz)
- Typical Range: ~50+ miles
- Faster switching (~3ms)
- Better performance in dense / urban RF environments
- Ideal for infrastructure-heavy deployments
VHF Configuration (150–174 MHz)
- Typical Range: ~60+ miles
- Superior terrain penetration (hills, vegetation)
- More reliable over wide, open areas
- Ideal for rural and long-distance networks
INTERFACES & CONFIGURATIONS
Supported Interface Options
| Code | Interface Type | Notes |
|---|---|---|
| S | RS-232 Serial | Standard DB-9 serial communication |
| T | Tech Series RS-485 | Multi-drop industrial communication |
| F | Tech Series RS-422 | Long-distance, noise-resistant comms |
| G | GPIO (optional) | Custom I/O / control applications |
How it Works
The M7 creates a transparent wireless data link by transmitting serial communications over RF. It connects field devices such as PLCs, RTUs, and sensors without requiring complex network infrastructure.
Deployments can be configured as:
- Point-to-point links
- Point-to-multipoint networks
- Repeater-based wide-area systems
This flexibility allows the M7 to scale from simple links to large distributed networks.
