In addition to smart home networking and office space scenarios, many IoT device connections will occur in remote environments. In these new environments, limitations in M2M transmission coverage will lead to accessibility issues and a need for power connections. To address this, widely adopted LPWA solutions—LoRaWAN and 3GPP (LTE Cat M1 and Cat NB1) open … Read more
With the continuous development of technology, the Internet of Things (IoT) has become an important application field in various industries. In the construction of smart cities, the use of smart water meters is becoming increasingly common. The LoRaWAN smart water meter solution is gradually receiving widespread attention and application.
