summarize
The IoT industry has manywireless technologyThese include carrier-operated wide area networks (WANs), such as 3G, 4G and 5G, as well as NB-IOT technology, and short-range transmission technologies that we often use, such asZigbee, Wi-Firespond in singingbluetoothetc.; all these technologies are mature, but need to make a trade-off between long distance and low power consumption; therefore, Low Power Wide Area Network (LPWAN) is gradually invented in this case, the abbreviation of LPWAN is LPWA, which is mainly for the characteristics of IoT industry: long-distance, low-power, low-bandwidth, and a large number of links. Among them, LoRa is favored by many users as a low-power WAN, although NB-IoT is in full swing under the promotion of operators, but because users still need to pay traffic fees every year and are subject to the requirements of operators' data channels, many users prefer LoRa technology to implement specific solutions.
Sensor applications for the medical industry
Hospital-specific temperatures for storing medications, organs, blood bags, vaccines, etc. play an important role for patient safety in the hospital and the quality of patient care in the hospital. Temperature and humidity monitoring solutions improve patient safety by monitoring current temperature and humidity and historical temperatures with full visibility.

LoRa has three major characteristics, first, the distance is far, the farthest transmission 15 kilometers; second, low power consumption, button battery can work for a year; third, because there is no operator participation, then do not need to pay fees to the operator every year. So LoRa has been well popularized and applied in many enterprises and institutions.
Taipei R&D team develops two products based on LoRa technology, one of them is LoRa data transmission DTU, which can transmit 4-channel RS-485 signals through LoRa; the other one is temperature and humidity transmitter, which can transmit temperature and humidity signals through LoRa.Mass production is expected in the fourth quarter of 2022Here's to the future.
