Networked Embedded Systems and M2M CommunicationBy the 1990s and early 2000s, the need for remote monitoring and automation led to the rise of networked embedded systems.Devices were enhanced with serial communication interfaces, GSM modules, and RFID tags, enabling them to exchange data with other machines. This gave birth to Machine-to-Machine (M2M) communication, a crucial intermediate step toward IoT. M2M in Industry:o Remote meter reading (electricity, water).o Fleet tracking using GSM/GPS modules.
