eSIM (Embedded SIM) is a technology that allows devices to embed a chip directly, enabling remote activation and switching of carrier networks without the need for a physical SIM card. It is driving a transformation in the way consumer electronics and IoT devices connect. The following table summarizes the main links in the eSIM industry … Read more
I²C (Inter-Integrated Circuit, pronounced “I-squared-C”) is a very elegant and widely used synchronous, serial, half-duplex communication protocol. Its core appeal lies in the fact that it can connect multiple devices using only two wires while sacrificing communication efficiency for individual devices. The bus data topology and device connections are shown in the following diagram: Taking … Read more
With the increasing number of attacks targeting WiFi, does this pose a threat to Internet of Things (IoT) devices? In short, the answer is yes. To elaborate, the answer is also affirmative: wireless networks are under attack — which means that all devices relying on wireless networks are also at risk of vulnerabilities. Intruders have … Read more
