What Is M2M Technology? The Power of Connectivity
M2M technology has been around for decades. The concept was introduced back in 1968, when Theodore Paraskevako conceived of a way for telephones to exchange caller information, representing the first instance of machine-to-machine communication.
IoT vs. M2M: What’s the Difference?
The Internet of Things (IoT) and Machine-to-Machine (M2M) communication have been around for years. This technology has revolutionized the way we do everything from agriculture and manufacturing to healthcare, transportation, and payment processing. Connecting sensors with electronic devices and applications enables consumers and businesses alike to automate processes and trigger actions based on data.
SIM Form Factors Explained
The capabilities of each form factor are the same, but they each have different dimensions, which makes them more suitable for specific kinds of devices. 2FF, 3FF, and 4FF SIMs have to be inserted into a device, while MFF2 SIMs have to be embedded—which is why they’re also called eSIMs. (1FF SIMs are no longer in use.).
