NODIX CEN-1

What is NODIX CEN-1?

Smart Bi-Link Anchor | Room-Level Certainty with Minimal Infrastructure

The NODIX CEN-1 is a next-generation, bi-directional BLE relay anchor engineered to deliver true room-level visibility with dramatically less infrastructure. Compact, battery-powered, and easy to install, it eliminates the traditional “one-gateway-per-room” requirement, removing one of the biggest barriers to RTLS adoption in high-density indoor environments. The NODIX CEN-1 changes the math. By acting as a bi-directional relay, it provides absolute room-level certainty without requiring a gateway in every single room.

Built for high performance and operational efficiency, the NODIX CEN-1 intelligently scans BLE tags inside its dedicated room, validates actual presence, and wirelessly relays verified data to nearby ZENIX gateways. This on-device filtering ensures accurate, real-time location insights without overwhelming the network.


How it Works?


The NODIX CEN-1 functions as an intelligent edge device within the RTLS ecosystem, bringing data processing closer to the source. Instead of forwarding raw BLE signals, it filters, validates, and structures data locally before transmission, ensuring higher accuracy while significantly reducing network load.

At its core, the CEN-1 continuously scans BLE tags within a defined room or enclosed space and applies RSSI-based filtering combined with proximity logic. This allows it to eliminate false or overlapping signals and accurately confirm true presence within a room boundary. Once validated, it assigns a precise Room ID and transmits only structured, reliable data to the gateway, enabling real-time visualization and analytics on the platform.

By shifting intelligence to the edge, Bi-Link ensures that only clean, context-aware data flows through the system, resulting in dependable room-level visibility.

Why Choose NODIX CEN-1?

The NODIX CEN-1 simplifies RTLS deployment with a zero-cabling, plug-and-play approach, enabling fast and hassle-free installation. It integrates seamlessly with existing systems, extending coverage into critical areas without added complexity. Designed for scalability, it allows easy expansion as your facility grows while keeping infrastructure and maintenance costs low. By processing data at the edge, it delivers reliable, real-time insights that enhance operational efficiency, patient safety, and asset utilization.

How Bi-Link Solves RTLS Challenges

Conventional RTLS systems rely on heavy infrastructure, often requiring a gateway in every room, extensive cabling, and continuous IT involvement. Despite this, they still struggle with signal bleed, inconsistent zone handovers, and noisy data, leading to inaccurate tracking and limited operational insight.

Bi-Link addresses these challenges by embedding intelligence directly into the NODIX CEN-1. By processing and validating data at the source, it removes noise, prevents false detections, and ensures that only accurate, room-level information is transmitted—eliminating the need for complex infrastructure and simplifying deployment.
