I. Optimize Anti-collision and Read/Write Parameters (Software/Configuration Level)

Optimize multi-tag anti-collision and congestion control settings: Enable efficient anti-collision algorithms on the reader, marking identified tags as dormant to avoid duplicate response conflicts; appropriately extend the single read duration and increase the number of information exchanges between tags and the reader to give densely packed tags sufficient response time and reduce missed reads.

Improve Communication Speed ​​to Adapt to Scenarios
Adjust communication speed according to the number of tags: Select an appropriate high-speed communication mode when tags are densely packed to balance decoding stability and reading efficiency, avoiding signal congestion caused by multiple tags simultaneously transmitting data.

II. Hardware and Antenna Layout Optimize
Rationally plan antenna direction, quantity, and installation angle
Arrange antennas at multiple angles to widen the radio wave coverage and avoid signal dead zones; adjust the antenna pitch and horizontal angles for pallets and conveyor belt goods to ensure that tags in different placement positions can be scanned.

Control Reader Interference
When multiple readers are operating simultaneously, ensure frequency and time slot isolation to reduce mutual interference of radio frequency signals between readers and avoid signal crosstalk leading to read failures.

III. Mitigating Signal Attenuation Issues Caused by Goods and Environment
Adapt to Goods and Packaging Materials
Metal and moisture-containing materials can severely weaken UHF signals. Metal products require anti-metal tags. Avoid attaching tags directly to metal surfaces; use foam padding to elevate the tags.

Standardize Goods Placement
Avoid tags blocking each other or facing away from the antenna. In inventory and conveyor belt scenarios, arrange goods rationally to reduce blind spots.

IV. Improve On-Site Environmental Conditions
Control the temperature and humidity of the operating environment. Abnormal temperature and humidity can affect the RF performance of the reader and tags. Adjust the antenna installation height according to the warehouse ceiling height to match the optimal reading distance; too far/too close will reduce reading performance.

In conveyor belt scenarios, also match the goods movement speed: Fast goods movement shortens the tag scanning time. Appropriately reduce the conveyor speed or increase the reading channel duration to ensure tags are fully recognized.
