Industrial Applications

1. Industrial Warehouse Smart IoT Gateway & AGV Telemetry

Deployed within smart warehousing environments to connect and control automated guided vehicles (AGVs) and field IoT sensors. Dual-band 1900 Mbps capabilities and 3x3 MU-MIMO enable steady concurrent communication with multiple moving endpoints over both 2.4 GHz and 5 GHz bands.

Problem Solved

Eliminates high latency and packet drop issues for moving warehouse automation machinery operating in dense racking spaces susceptible to RF interference.

2. Control Cabinet Network Edge Bridge

Installed near or within standard electrical enclosures to serve as a high-speed local network bridge for diagnostic computers, PLCs, and local logging instruments. The 12VDC power requirement cleanly integrates with standard plant auxiliary power distributions.

Problem Solved

Provides field maintenance engineers with secure wireless PLC parameter configuration access via isolated guest SSIDs or AP isolation, bypassing the need for hazardous physical network connections.

3. CNC Machining Shop Floor Production Monitoring

Utilized in machining cells to facilitate large CAD/CAM program distribution and local machine metrics telemetry. The six high-gain antennas and beamforming focus the wireless connection directly toward machine tool terminals.

Problem Solved

Prevents bandwidth congestion on the factory network by separating heavy mechanical CAM file updates (utilizing high-speed 5 GHz) from real-time operational machine monitoring (using 2.4 GHz).
