UHF RFID Ceiling Reader
RLC-100 UHF RFID Ceiling Reader
Monitor tagged movement from above with overhead RFID coverage, sensor-triggered detection and edge event handling. RLC-100 is designed for controlled entrances, asset rooms and operational checkpoints, with Android-based processing, local caching and direct system communication.
* Sensor type, read rate, read distance and interface availability depend on the selected configuration. RFID performance depends on tag type, tagged material, mounting height, antenna design, orientation, RF settings, movement path, interference and site conditions.
Why Use RLC-100?
Create an automatic RFID monitoring point above the operational route
Use RLC-100 where tagged assets pass through a defined entrance, room or checkpoint and the project needs event capture, local processing and alert integration without placing reader equipment in the traffic path.
Monitor the route without using floor space
Install the reader above or beside the monitored zone to keep the passage clear while capturing compatible tagged items moving through the intended area.
Trigger monitoring around detected movement
Use the confirmed infrared or radar configuration to support event-driven RFID reading and audible or system alerts at controlled entrances and asset zones.
Process, cache and route events locally
Use Android-based edge handling, local caching and HTTP, MQTT, TCP or UDP communication to reduce raw-data traffic and maintain event continuity during temporary connection loss.
Before / After
From manual zone checks to automatic overhead RFID event capture
Replace repeated observation and item-by-item confirmation with a configured overhead checkpoint that detects movement, captures compatible tags and forwards a validated event.
Manual asset-zone checking
Five repeated actions at the monitored area
The process depends on an operator being present and completing the same confirmation sequence for each movement.
Automatic overhead RFID capture
Three stages at the configured monitoring point
RLC-100 supports zone-event monitoring; it does not by itself provide exact real-time item coordinates, guaranteed person-to-item association or room-wide inventory coverage. Final behavior depends on the complete hardware, tag, sensor, mounting and software design.
Overhead RFID Zone Monitoring
Monitor tagged movement without placing equipment in the traffic path
Mount the reader above or beside a defined route and configure the RFID, movement-sensing, alert and event-forwarding behavior around the actual operational checkpoint.
Capture compatible tags, process the event locally and send the result to the approved application or alert workflow.
Entrance / Exit Passage
Monitor tagged merchandise, documents, equipment or returnable assets moving through a defined doorway or corridor.
Asset Room
Record tagged tools, devices, samples or controlled assets entering or leaving a storage or service area.
Service Counter
Support RFID-based check-in, check-out, return or exception workflows above a defined desk or transaction zone.
Industrial Checkpoint
Capture tagged materials, carriers or work-in-process items at a warehouse or production transition point.
A ceiling reader does not automatically cover an entire room. Coverage depends on mounting height, antenna pattern, tag orientation, tagged material, RF output, surrounding metal, movement path, interference and the required separation from adjacent zones.
Event System Architecture
Detect movement, capture RFID tags and route the resulting event
RLC-100 combines the selected movement sensor, UHF RFID engine, Android processing platform, local cache, alert functions and network protocols in one mounted monitoring terminal.
Movement Enters Zone
A person, asset or tagged item moves through the configured monitoring area.
Infrared / Radar Trigger
The confirmed movement-sensing configuration activates or supports the monitoring workflow.
UHF RFID Capture
The RFID engine collects compatible tag responses within the project-specific read zone.
Edge Event Handling
Local processing filters repeated reads and applies the approved device-side event logic.
Cache / Alert
Events can be cached during a connection interruption or used to support an audible, visual or external alert.
Business System
HTTP, MQTT, TCP or UDP forwards the event to the project application, WMS, MES, security platform or IoT service.

Record tagged books, files, tools, devices or controlled assets entering or leaving a defined room and compare the event with the approved transaction or authorization workflow.
Warehouse & Manufacturing Checkpoints
Capture tagged cartons, returnable containers, tools or work-in-process items at receiving areas, material rooms, production transitions or dispatch passages.
Deployment Guidance
Design the overhead read zone around the route, tag and trigger
The stated read distance is not the design target by itself. Build the monitoring point around the real mounting height, passage geometry, tag orientation, tagged material, sensor behavior and adjacent RFID zones.
Validate the complete event—from movement detection and RFID capture through local processing, alert behavior and system receipt—under the operating conditions expected at the site.
Define the asset route, passage width, installation surface, service access and the area that must remain outside the intended read zone.
Confirm the sensor option, antenna configuration, RF power, tag orientation and timing needed to capture the intended movement without excessive nearby reads.
Test the final protocol payload, duplicate handling, connection-loss behavior, recovery process, buzzer or external alarm and business-system response.

RLC-100 ceiling-reader, sensor and read-zone questions
How is RLC-100 different from a conventional fixed RFID reader?
RLC-100 is designed as an overhead or wall-mounted monitoring terminal that combines UHF RFID reading, Android-based edge processing, local caching, network protocols and a configurable infrared or radar sensing option. A conventional fixed reader may require separately positioned antennas and external event-processing software.
Is the stated read distance of up to 3.5 m guaranteed?
No. The supplied document states up to 3.5 m depending on the tag and antenna configuration. Actual performance depends on mounting height, tag type, tagged material, orientation, RF power, surrounding metal, movement path, interference and the required read-zone boundary.
Can RLC-100 locate the exact position of every tagged item?
The supplied information supports RFID zone monitoring and asset-movement workflows, not precise real-time coordinates. Exact location, person-to-item association or RTLS functions require additional confirmed hardware, algorithms and system design.
Are infrared and radar sensors both included?
The supplied document states infrared or radar sensing. Confirm whether the quoted RLC-100 configuration uses infrared, radar or another sensor option and whether the function is standard or optional.
Can the reader support unauthorized-movement alerts?
It can support an RFID-based alert workflow using movement sensing, tag capture, local logic, audible or buzzer output and a connected application. The final authorization rules, transaction data and alarm escalation remain part of the project software and system design.
Can RFID events be sent to WMS, MES, security or IoT platforms?
The supplied information lists HTTP, MQTT, TCP and UDP. These protocols can be used in a project-specific integration layer, but this page does not claim a native connector for every WMS, MES, security or IoT platform.
