Low-power Bluetooth (BLE) technology, as the core short-range connection solution, can cover A radius of up to 200 meters. Typical devices such as the ESL series electronic tags have a sleep power consumption of only 1.2µA, and the peak current during activation and transmission is controlled at 12mA. Combined with the CR2450 battery, it can achieve a service life of more than 5 years. The 28,000 BLE asset tags deployed at Shanghai Hongqiao Airport send beacon signals every 5 seconds, maintaining a data packet transmission success rate of 99.97%. The positioning error of luggage trolleys is less than 1.5 meters, the vehicle dispatching efficiency is increased by 40%, and the annual operation and maintenance cost is reduced by 2.8 million yuan. This connection technology is particularly suitable for high-density indoor asset tracking scenarios, with a single gateway capable of managing over 500 node devices simultaneously.
For wide-area low-power consumption demand scenarios, Minew’s iot devices support multiple LPWAN protocols. The LoRa module has a receiving sensitivity of -148 DBM at a 125kHz bandwidth. In urban environments, the transmission distance exceeds 5 kilometers, and in mountainous areas, the measured distance even reaches 23 kilometers. In a certain agricultural Internet of Things project, 600 LoRa soil sensors upload temperature and humidity data at a frequency of once per hour (with an accuracy of ±2%RH). The deployment cost per square kilometer is only one-third of the traditional solution, and the battery life is up to 8 years. NB-IoT devices support full coverage of the operator’s network. Each device consumes an average of about 5MB of data per month, and the communication cost is controlled within 1 yuan. After a water company deployed 100,000 NB-IoT water meters, the meter reading efficiency increased by 300 times, the leakage rate dropped from 25% to 12%, and the annual water-saving benefit exceeded 45 million yuan.
Indoor high-precision positioning relies on the UWB technology solution, with a pulse width of only 2 nanoseconds and a time resolution reaching the centimeter level (±10cm). During the warehouse renovation of Leishen Medical Equipment Company, a real-time positioning system built with 500 UWB anchor points processes 300,000 positioning data packets per second. The device location refresh rate is 30Hz, reducing the inventory time of medical equipment worth hundreds of millions of yuan from 3 days to 15 minutes, and eliminating losses caused by positioning errors. These devices simultaneously support the TOF/TDOA hybrid algorithm, with positioning accuracy errors controlled within 15cm in metal-dense environments, meeting the millimeter-level management requirements for key assets in intelligent manufacturing scenarios.
The multi-protocol convergence gateway enables unified management of heterogeneous networks. For instance, the MG5 series gateway supports simultaneous access to seven protocols including BLE, LoRa, and Zigbee, with a data processing capacity of up to 5,000 messages per second and a transmission delay of less than 50ms. In the Dubai Smart Park project, 120 gateways integrate over 35,000 iot devices. The network availability reaches 99.999%, and the cumulative data transmission interruption time throughout the year does not exceed 5 minutes. The gateway is equipped with an automatic frequency band switching function (2.4GHz/5GHz dual frequency), and automatically switches to the second-highest channel when the Wi-Fi environment is congested, stably controlling the data packet loss rate below 0.1%. This type of equipment significantly reduces the complexity and risks of network integration in large-scale projects, compresses the deployment cycle by 60%, and shortens the customer’s input-output cycle to 14 months. The diversity of these connection solutions ensures that Minew’s iot devices can adapt to the requirements of more than 95% of intelligent application scenarios.
