The XetaWave XETA4B-22MMDFB-IO is a premium industrial software-defined radio engineered for licensed 450-470 MHz UHF MAS networks, where long-range reliability, spectrum protection and deterministic performance are critical. Housed in a rugged metal enclosure and built on an open Debian Linux platform, it combines high-performance narrowband RF with eight programmable I/O channels, allowing sensors, alarms, valves, pumps and contact points to be wired directly into the radio without a separate RTU or I/O module.

For organisations running licensed UHF telemetry networks, the XETA4B-22MMDFB-IO provides a modern, supported migration path away from ageing narrowband radio fleets. It preserves existing licensed spectrum investment while delivering contemporary IP networking, embedded computing, stronger security and remote diagnostics — making it well suited to retrofit, replacement and network modernisation projects across water, utilities, energy and resources.

• Modbus RTU and Modbus TCP support
• Designed and manufactured in the USA

Integrated I/O Without Additional Hardware

The eight onboard I/O channels can be independently configured to suit the site, supporting analog inputs, analog outputs, digital inputs, digital outputs and pulse counting. This allows a single device to act as radio, protocol gateway and remote I/O point.

Typical uses include:

• Tank and reservoir level monitoring
• Pump start/stop and run status
• Valve position control and feedback
• Flow meter pulse counting
• Alarm and fault reporting
• Door, intrusion and power-fail contacts
• Analog process signals such as pressure and temperature

Consolidating radio and I/O into one unit reduces panel space, wiring, commissioning time, spares holdings and total installed cost per site.

Licensed Spectrum for Mission-Critical Networks

Operating in licensed UHF spectrum gives network owners protected channels, predictable performance and resilience against congestion — a decisive advantage for critical infrastructure where unlicensed bands are increasingly crowded. The XETA4B-22MMDFB-IO supports narrowband channel plans while still delivering modern Ethernet and serial connectivity, letting operators run legacy serial RTUs and IP-based equipment across the same network during phased upgrades.

Ideal Applications

• Water and wastewater SCADA networks
• Pump station and reservoir telemetry
• Electricity utility and substation monitoring
• Pipeline and oil and gas remote monitoring
• Mining site communications
• Irrigation and agricultural water management
• Renewable energy and battery storage monitoring
• Environmental and flood monitoring
• Industrial automation and process control
• Remote asset and alarm monitoring

Designed for Network Modernisation

Many licensed UHF telemetry networks across Australia are running on radio platforms nearing end of support. The XETA4B-22MMDFB-IO is designed to slot into these environments as a like-for-like replacement while adding Ethernet connectivity, embedded Linux computing, encryption and integrated I/O — allowing utilities and industrial operators to modernise progressively rather than replacing an entire network at once.

Whether expanding an existing licensed network, replacing obsolete narrowband radios, or building a new UHF telemetry system, the XETA4B-22MMDFB-IO delivers the performance, durability and flexibility required for long-life critical infrastructure.
