Highly stable. Unlike single-frequency RFID, Bluetooth uses 3 frequencies, enhancing stability and interference resistance. Features password protection, tamper-proof, and unauthorized use prevention.

Uses 2.4G band, internationally open frequency. Low emission power of 1mW, no electronic device interference.

0 dBm to -20 dBm, broadcast interval default 500ms, adjustable.

Generally 3-10 meters.

Meter-level positioning, accuracy depends on beacon spacing. 8-10 meters spacing achieves 3-5 meters accuracy; 10-15 meters spacing achieves 5-10 meters accuracy.

Basic accuracy: minimal drift, reflects walking trajectory.

Good accuracy: continuous results, minimal drift.

Excellent accuracy: continuous, accurate, no significant drift.

Beacon quantity estimation: Basic – 300400 sqm/beacon, Good – 150225 sqm/beacon, Excellent – 100~150 sqm/beacon.

Less than 0.1% based on project statistics.

Advanced power control technology. R5C: 4-5 years, R5: 5-7 years, L3: 1 year, C3: up to 10 years. Batteries replaceable.

C3 series withstands harsh environments, operating from -40 to 85 degrees Celsius.

Check via APP.

Maximum 120 meters.

Yes, increase node density or adjust transmission power for complex environments.

Minimal interference due to short broadcast time and limited channel usage.

Battery-powered, independent, no wiring needed, minimal impact on other devices.
