There are billions of IoT devices out in the world already, with many more being invented, designed, and introduced constantly. There are many connectivity technologies like Bluetooth, BLE, Wi-Fi, ZigBee, ANT, LoRa and SIGFOX that set guidelines for the IoT data transfer and communication.
Depending on the IoT’s application, factors such as range, data requirements, security, power demand, and battery life will dictate the choice of one, or some form of combination of connectivity technologies.
Choosing the right connectivity fit for every device is highly important, as well as choosing the right Crystal device. There are various of Crystal and Oscillator specifications that are designed for connectivity uses, including special designs for crystal mold inside modules, wider temperature range, and higher stability.
