Application in IoT 

  • Smart Metering: accurate billing, remote monitoring, and efficient energy management. 

  • Asset Tracking: logistics operations, supply chains. 

  • Environmental Monitoring: monitoring pollution levels, optimizing resource usage, and ensuring a sustainable environment. 

  • Healthcare: wearable devices, virtual consultations, and timely medical assistance. 

Structure and Functionality of 3G 

The structure of 3G networks involves base stations, mobile devices, and core network components. Here's how it works: 

  • Base stations or Node B are access points for mobile devices to connect to the 3G network. They get and transfer data signals, providing seamless communication between devices and the network. 

  • 3G-enabled devices, such as smartphones, tablets, and IoT sensors, utilize the 3G network to access the internet, make calls, and transmit data. These devices are equipped with SIM cards that authenticate and authorize network access. 

  • Core Network implies various elements, including the mobile switching center (MSC), serving GPRS support node (SGSN), and gateway GPRS support node (GGSN) enable call routing, data transfer, and network management.
