In today’s data-driven facilities and data centers, reliable environmental monitoring is non-negotiable. Temperature swings, humidity changes, water leaks, or airflow issues can quickly escalate into costly downtime or equipment damage. Traditional wired sensors often mean expensive conduit runs, long installation times, and limited flexibility when layouts change.

Enter the RLE Environment Monitoring WiNG wireless monitoring platform. This robust, battery-powered solution delivers long-range performance with minimal maintenance and easy integration into existing Facility Management Systems (FMS), Building Management Systems (BMS), Energy Management Systems (EPMS), or Data Center Infrastructure Management (DCIM) platforms.

What is the RLE WiNG Platform?

WiNG is RLE Environment Monitoring’s advanced wireless sensor ecosystem designed for critical environments. It consists of:

Compact, long-life wireless sensors
A central WiNG-MGR v2 gateway (with support for the latest firmware versions)
Optional WiNG-RXT range extenders for even greater coverage

Sensors communicate using a proprietary 900 MHz (North America) or 868 MHz (international) signal that offers exceptional penetration through walls and obstacles — up to 270 feet through one wall, 100 feet through multiple walls, and 600 feet line-of-sight. With range extenders, you can push coverage to 1,000 feet.

One of the biggest advantages? Battery life up to 12 years at room temperature (still excellent at higher temperatures). That means dramatically reduced maintenance compared to many other wireless solutions.

Key Sensors and Monitoring Capabilities

The WiNG platform supports a wide variety of sensors, making it highly versatile for facilities and server rooms:

You can deploy up to 250 sensors per WiNG-MGR (expandable to ~400 with extenders), giving you scalable coverage across large or complex facilities without pulling new cable.

WiNG-RXT – Wireless Range Extender

The WiNG-RXT is a powerful range extender that significantly expands the coverage of your WiNG wireless monitoring system. It acts as a repeater between the WiNG sensors and the WiNG-MGR v2 gateway, making it ideal for large facilities, complex layouts, or challenging RF environments, such as thick walls, metal structures, or long distances.

Typical applications: Large data centers, multi-story buildings, warehouses, remote equipment rooms, or any installation where sensors are located beyond the standard 600 ft line-of-sight range
Range extension: Adds up to 1,000 feet (305 m) direct line-of-sight between the extender and the WiNG-MGR (or another RXT). Sensors can communicate up to 600 ft line-of-sight to an RXT.
Multiple units supported: You can chain several WiNG-RXT units to create a mesh-like coverage area and support up to approximately 400 sensors per WiNG-MGR system
Power: Powered by the included 5VDC wall adapter (no battery required for the extender itself)
Includes: Three antennas, wall mounting brackets, and a power supply with multiple blade options for international use
Easy setup: Plug in power and mount — the system automatically recognizes the extender with no complex configuration needed

By strategically placing one or more WiNG-RXT units, you can achieve reliable wireless coverage across much larger or obstructed areas without running new cabling or adding extra gateways. This makes the entire WiNG platform even more flexible and cost-effective for expansive facility monitoring deployments.

Easy Integration into Your BMS, EPMS, or DCIM Platform

This is where WiNG really shines for integrators and facilities/operations teams.

The WiNG-MGR v2 gateway (including the latest firmware releases) provides multiple open-protocol options:

Modbus RTU (via RS-485) and Modbus TCP/IP
BACnet MS/TP and BACnet/IP
SNMP (v1/v2c/v3) for network management systems
Onboard web interface for local viewing, trending (up to 30 days of historical data), and basic alarming

For tighter integration without a full gateway UI, the BMS-WiNG module is purpose-built. It supports up to 50 sensors and acts as a clean protocol translator, feeding data directly into your BMS, EPMS, or DCIM via Modbus RTU or BACnet MS/TP. Auto-discovery of sensors makes setup fast, and it requires no separate software or licensing fees.

Using our Vykon by Tridium solution, we can set up these sensors for longer trending, advanced alerts, and push the data via the JSON toolkit to an MQTT broker. This gives you powerful options for enterprise-level monitoring, custom dashboards, and integration with modern IoT platforms.

This robust Modbus and SNMP (including v3) support is especially valuable when bridging wireless sensors into platforms like Nlyte NEO, where you can map registers or OIDs to points for trending, alarming, energy calculations, and centralized dashboards in your DCIM or EPMS environment.

Real-World Benefits for Facility and Data Center Teams

Faster Deployments — Mount sensors in minutes using magnets, screws, or zip ties. No conduit, no long cable runs.
Lower Total Cost of Ownership — Long battery life, no licensing fees, and free firmware updates.
