RFID Reader for Inventory Management with 8 Antenna Ports
8-Port UHF RFID Reader for Multi-Zone Inventory Tracking
This RFID reader for inventory management provides eight TNC antenna ports for fixed UHF RFID systems that require multiple antenna positions across warehouse or inventory checkpoints.
The reader supports EPC C1G2 and ISO 18000-6B/C, RF output up to 33 dBm ±1 dBm, and tag identification speeds of more than 1,000 tags per second.
Ethernet, RS232, RS485, WiFi and Bluetooth provide several options for transferring RFID data to inventory software or other system applications. RSSI, tag filtering and antenna-status functions are also available for RFID system configuration and data processing.
Eight Antenna Ports for Inventory Coverage
Up to eight external UHF RFID antennas can be connected through the TNC antenna ports.
This allows antenna positions to be distributed across different inventory checkpoints such as receiving areas, material-transfer points, conveyor sections and shipping zones.
Compared with a reader offering fewer antenna ports, an 8-port configuration provides more flexibility when one RFID reader needs to serve several fixed antenna positions. The actual number and placement of antennas should be determined by the site layout and required reading zones.
High-Throughput RFID Inventory Capture
The reader supports an identification speed of more than 1,000 tags per second, making it suitable for inventory checkpoints where many tagged items may enter the reading area within a short period.
Tag RSSI and filtering functions can help the software process RFID data according to the project configuration. Dense reader operation is also supported for installations where multiple RFID readers may be deployed in the same environment.

RFID Functions for Inventory Systems
The reader includes functions that can support fixed multi-zone RFID deployments:
- Dense reader operation
- Tag RSSI reporting
- Tag filtering
- Antenna standing-wave detection
- Online firmware upgrade
- Fixed-frequency and frequency-hopping modes
- External input and relay output control
These functions are especially useful where several antennas or multiple RFID checkpoints need to be managed as part of one inventory-reading system.
Typical Inventory Applications
- Warehouse Inventory Monitoring
External antennas can be positioned around receiving, storage and shipping areas to identify tagged inventory at defined checkpoints. - Receiving & Shipping Checkpoints
Suitable for reading tagged pallets, cartons or assets as they enter or leave warehouse areas. - Conveyor & Material Flow
Eight antenna ports provide flexibility for placing antennas around conveyor sections, transfer points or material-handling routes. - Large-Area Asset Inventory
Can be used where several fixed antenna positions are required to monitor tagged equipment or assets across a larger operational area.

Frequently Asked Question
The top questions about RFID reader for inventory management
An 8-port reader allows up to eight external RFID antennas to be connected to one reader. This provides more flexibility when several fixed inventory checkpoints or antenna positions need to be covered.
The reader provides eight TNC antenna ports for compatible external UHF RFID antennas.
Yes. Antennas can be positioned at different reading points according to the warehouse layout, RF cable arrangement and required reading zones.
The specified tag identification speed is more than 1,000 tags per second under suitable operating conditions.
RFID data can be transferred through Ethernet, RS232, RS485, WiFi or Bluetooth. Integration with a specific WMS, ERP or inventory platform depends on the software interface and project implementation.
The specified reading distance is 0–20 meters, while writing distance is up to 10 meters. Actual performance depends on the external antenna, RFID tag, RF output power and installation environment.
