How Does System on a Chip (SOC) Work?
To understand iSIM, we need to get a better view of what it means to integrate with the device SOC. A complex IoT device may have a number of different tasks to complete, such as connecting to WiFi, processing audio, visuals, or even tactile sensations, graphics processing, and sending and receiving data. Using multiple chips adds to the cost and the complexity of manufacturing devices.
By integrating the SIM directly into the SOC, and hosting the operating system of the SIM on the same chip, costs are heavily reduced, alongside power consumption - critical for battery-powered IoT devices where battery life is so important. By reducing the footprint on the printed circuit board (PCB), enterprises and device manufacturers can save costs by simplifying their bill of materials, while also reducing space and power consumption.
