What Is 3G? Third Generation Cellular Networks Explained
3G networks operate on frequency bands between 400 MHz and 3GHz. While they consume 50 percent more power than 2G networks, they also provide greater spectrum efficiency, making them suitable for a wider range of applications.
What Is a Mobile Switching Center (MSC)?
When a device attempts to access a GSM or CDMA-based network, it connects to the network’s nearest Base Transceiver Station. The Base Station Controller then relays the connection to the MSC, which is part of the Network Switching Subsystem.
What Is GSM? The Global System for Mobile Communication Explained
GSM is currently the most widely used network technology in Internet of Things (IoT) applications for its simplicity, affordability, and accessibility. But that’s likely to change over the next few years.
