What Is Cellular IoT? Simple, Global Device Connectivity
Cellular IoT uses cellular networks to connect physical devices to the Internet. The same cell towers that provide service to your smartphone can connect heavy machinery, security systems, hospital equipment, asset tracking systems, and billions of other devices to the internet. Cellular connectivity enables these devices to transmit and receive data, so end users can remotely monitor, analyze, and control them.
What Is IoT Connectivity: A Comparison Guide
Connectivity is a critical component of the Internet of Things. IoT devices rely on networks to communicate with gateways, applications, servers, routers, and other IoT devices. This communication—transmitting and receiving data—enables IoT devices to perform the functions they were designed for.
What is an eSIM?
Traditionally, if you wanted to switch your cellular device's carrier you had to replace the SIM with one from the new carrier. With phones and tablets, this is a simple task. However, for thousands of remotely deployed IoT devices, swapping out SIMs is problematic, especially for devices with embedded SIM form factors that are soldered. In such cases, the SIM is stuck in the device.
