IoT Gateway MG4 Rechargeable PoE Gateway
Introduction

Reliable Monitoring Edge Intelligence

24/7 Visibility Across Critical Facilities

The MG4 Rechargeable PoE Gateway ensures continuous operational visibility in challenging environments. Its dual-chip design maintains stable backhaul while scanning Bluetooth signals with high throughput and low latency, delivering critical data to the cloud in real time. Powered by PoE for easy installation and remote recovery, it features a built-in battery and store-and-forward buffering to preserve data during power or network outages, automatically syncing once restored.
By reducing radio noise through smart filtering and leveraging BLE 5.1 extended advertising, the gateway provides richer context with fewer transmissions. This results in cleaner data, improved analytics, and reliable visibility across facilities, assets, and operations-without overbuilding the network.

Data

Data Reliability and Timeliness

Never miss critical data. Dedicated processing by the nRF52833 ensures precise and timely handling of Bluetooth advertisements, guaranteeing data integrity and system reliability.
Reduced

Reduced Latency & Seamless Experience

Experience zero lag in critical applications. Dual-antenna isolation and specialized scanning reduce latency, ensuring time-critical data is processed efficiently and delivered to your system on schedule.

Minimize Latency To Ensure Timely Transmission Of Time-Critical Data

HIGH PERFORMANCE

Dual Chip Architecture Boosts Concurrency

ESP32-S3 handles application processing while Nordic nRF52833 handles Bluetooth signal scanning and parsing Bluetooth 5.1 extended advertisement packets. The dual-chip split and dual-antenna isolation keep frame rates high, up to 350 packets per second, reduce latency, and prevent backlog, so that time-critical data reaches systems on schedule.

Advantages

Resilient Ethernet & Wi-Fi Backhaul With Failover

Use Gigabit Ethernet as a stable backhaul with Wi-Fi on standby for temporary deployments. If the link becomes unstable, traffic can be switched in seconds to keep critical services running. The MG4 gateway’s local store-and-forward buffer preserve every record during disruptions and sync on return.

Edge Filtering Delivers Clean Data

Use RSSl thresholds, MAC lists, or regex on raw data to filter traffic at the edge. lt ensures high-quality communications in RF-congested environments and reduces bandwidth use and cloud costs.
advantages

  • Enhanced Data Quality

    Ensure clear communications in crowded RF environments. Filtering unreliable raw data at the edge guarantees only high-quality information is processed.
    Enhanced

  • Increased Efficiency

    Boost system efficiency by eliminating noise. Edge filtering uses Regex and threshold checks to quickly reduce data volume, speeding up cloud tasks.
    Increased

  • Reduced Operating Costs

    Cut cloud and bandwidth expenses instantly. By pre-filtering irrelevant traffic using MAC lists or RSSI, only essential data is transmitted.

Advantages

More Safety Features

Fast Safe Configuration With MinewLink

Configure with the MinewLink App using smart config, Bluetooth onboarding, or AP setup. Teams finish setup faster, reduce errors, and avoid return visits. Large rollouts are simpler to stage, verify, and hand over.

Preassigned Static IPs Simplify Operations

With preconfigured static IP addresses for batch deployment, devices are ready to use at power-up. No per-device setup or DHCP conflicts hurting uptime. Just constant access and visibility.
