In an industrial metal environment, bluetooth repeater can penetrate a 20mm thick steel plate (signal attenuation ≤10dB), extending the communication coverage radius of asset tags from 15 meters to 85 meters, with an improvement range of 467%. The actual test at the Siemens Amberg factory shows that after deploying the MBT02 in the densely equipped area, the success rate of tag data return transmission has jumped from 63% to 99.8% (with an average daily communication volume of 1.2 million times), the real-time positioning accuracy has improved to ±0.3 meters (originally ±5 meters), and the AGV material search efficiency has increased by 40% (annual labor cost savings of €580,000).
The multi-protocol concurrent capability breaks through the communication bottleneck. The MBT02 supports the simultaneous connection of 256 Bluetooth 5.1 tags (with a data throughput of 2Mbps). Under the electromagnetic interference of 100 welding robots (intensity of 30V/m), the data packet loss rate is compressed to 0.05% (baseline value of 22%). The case of Bosch Stuttgart factory has confirmed that this equipment has reduced the asset inventory time from 8 hours to 25 minutes (with an efficiency improvement of 95%), increased the inventory accuracy rate from 87% to 99.6%, and reduced raw material waste by 18% (approximately €240,000 per year).
The dynamic environmental adaptability optimizes the operating cost. Through the RSSI three-source localization algorithm (with an error correction rate of 65%) and the temperature compensation module (stable operation from -40℃ to 85℃), the label reading completeness rate of MBT02 in the cold chain warehouse reaches 100% (compared with the traditional solution of 83%). After the deployment of the Japanese cold chain logistics company Maruha Nichiro, the asset loss rate of refrigerated trucks dropped from 4.7% to 0.2% (annual avoided loss ¥92,000,000), and the power consumption of the equipment was only 0.5W (with a 5-year battery maintenance-free cycle).
The security architecture meets industrial-grade requirements. Based on AES-256 encrypted transmission (NIST FIPS 140-2 certification) and MAC address whitelist filtering (with an accuracy of 99.999%), Foxconn’s Shenzhen factory has achieved zero network intrusion for 18 consecutive months (previously, there were an average of 12 security incidents per year). The OTA upgrade for vulnerability repair takes less than 3 minutes (the traditional solution requires a 2-hour downtime), avoiding a loss of €150,000 for each downtime.
The cost-benefit model is remarkable. The unit price of a single MBT02 unit is €420 (covering an area of 5,000 square meters), which is 76% lower than the cost of industrial WiFi base stations. Calculations from Volkswagen’s Wolfsburg plant show that by replacing the old system with 50 MBT02 units (with a total investment of €21,000), the communication delay of asset tags was reduced from 350ms to 32ms (a decrease of 91%), and the investment was recovered in 2.7 months (ROI of 528%). It also supports Mesh networking (node hop transmission ≤7 hops), and the deployment cost in a 200,000-square-meter factory is €2,300,000 lower than that of the wired solution.
The disaster recovery capability has been empirtically verified. During the 2023 earthquake in Turkey (with a magnitude of 7.8), the MBT02, which adopted the seismic design (EN 60068-2-6 standard), maintained 100% operation in an environment with a vibration frequency of 33Hz and an amplitude of 3.5mm, ensuring that 92% of the key equipment completed the positioning and inventory within 48 hours after the disaster. The damage rate of traditional RFID systems reaches 34%.
This device is driving the upgrade of Industry 4.0: integrating the Edge AI engine (latency < 8ms) to achieve local preprocessing of label data, the Airbus Hamburg plant has verified that it has reduced the false alarm rate of equipment failures by 78% in predictive maintenance. ABI Research predicts that by 2027, smart factories adopting such bluetooth Repeaters will increase asset utilization by 23% (with an annual global economic value of $21.7 billion).
