We often get customer's inquiry and ask if we can provide a high gain antenna, someone even says the higher gain the better. But is that true? Is really higher gain antenna result a better effect? In fact, this view is incorrect. Simply to increase the gain, although the coverage distance is greater, the coverage will become narrower.
+The total number of wireless IoT connections will increase from 1.5 billion at the end of 2019 to 5.8 billion in 2029. But the growth rates for the number of connections and connectivity revenue will be somehow lower than previous forecast. This is partly due to the negative impact of the COVID-19 pandemic...
+Nowadays, the application of remote wireless transmission is increasing year by year, such as small amount of data between devices like water meters, smoke detectors, and the use of long-distance transmission. Let's take Smart Water Meter reading system as an example, to explain how LoRa module works in the AMR.
+Switching value signals is a digital signal. Compared with analog signal, it has strong anti-interference ability. The change of the switching value signal is not continuous, so it is so called pulse signal. If an RF module uses switching value signals to communicate, we call it Switching Value RF module.
+Door Sensor is composed of a wireless transmitter module and a magnetic block. There is a "reed switch" inside the wireless transmitter module. When the distance between the magnet and the reed switch is within 1.5cm, the reed switch is disconnected. Once the distance exceeds 1.5cm, it will alarm
+Just as the literal meaning of "IoT = Things + Internet", data transmission is required to connect to the Internet. The non-contact data transmission is the application scenario of radio frequency. Almost all IoT products will have RF transmission. The RF transmission with low transmit power has a short distance...
