2G/2.5G: 2G connectivity remains a prevalent and viable IoT connectivity option due to the low cost of 2G modules, relatively long battery life, and large installed base of 2G sensors and M2M applications. ○ 3G: IoT devices with 3G modules use either Wideband Code Division Multiple Access (W-CDMA) or Evolved High Speed Packet Access (HSPA+ and Advanced HSPA+) to achieve data transfer rates of 384Kbps to 168Mbps. ○ 4G/Long-Term Evolution (LTE): 4G/LTE networks enable real-time IoT use cases, such as autonomous vehicles, with 4G LTE Advanced Pro delivering speeds in excess of 3Gbps and less than 2 milliseconds of latency. ○ 5G: 5G cellular technology provides significant enhancements compared to 4G/LTE networks and is backed by ultra-low latency, massive connectivity and scalability for IoT devices, more efficient use of the licensed spectrum, and network slicing for application traffic prioritization.
Satellite: ○ C-band: C-band satellite operates in the 4 to 8 gigahertz (GHz) range. It is used in some Wi-Fi devices and cordless phones, and in surveillance and weather radar systems. ○ L-band: L-band satellite operates in the 1 to 2GHz range. It commonly is used for radar, global positioning systems (GPSs), radio, and telecommunications applications.
