What Is Transmission Control Protocol (TCP)?

22.12.2020 – Knowledge Hub

Unlike User Datagram Protocol (UDP)—another standard that applications use to exchange data—TCP is designed for accuracy, not speed. In data transport, data packets can sometimes arrive out of order or get lost. TCP numbers each packet to ensure that every piece reaches its destination and can be rearranged if needed. When packets don’t arrive within a specified timeframe, Transmission Control Protocol requests re-transmission of the lost data.

What Is User Datagram Protocol (UDP)?

22.12.2020 – Knowledge Hub

When higher-level protocols need to transmit data quickly, they rely on UDP to package and distribute that data over the Internet Protocol (IP). (If you wish to know more about protocols and IoT check out our Comprehensive Guide to IoT Protocols.)

What Is 5G? Everything You Need to Know

22.12.2020 – Knowledge Hub

5G networks are vastly improving high-speed Internet connectivity around the globe and opening the door to a revolution in the Internet of Things (IoT). There are already billions of IoT devices, but the wider bandwidth and more efficient spectrum usage of 5G networks will allow far more devices to operate in close proximity without interfering with one another.

What Is an APN? Access Point Names Explained

22.12.2020 – Knowledge Hub

Basically, your APN defines your connectivity settings. And any time you change carriers, you need a new APN—because the name is specific to each MNO.

What Is an SMSC? Short Message Service Center

22.12.2020 – Knowledge Hub

When a device sends an SMS message, it goes to the SMSC first, and then the SMSC forwards it to the intended recipient. If the recipient is unavailable (usually meaning the device is off or doesn’t have service), then the SMSC will store the message until either the device becomes available again or the SMS expires.

Narrowband IoT (NB-IoT) Explained

22.12.2020 – Knowledge Hub

These Low Power Wide Area Networks (LPWANs) allow a greater volume of devices to share bandwidth than traditional cellular networks like 2G, 3G, and 4G. They enable devices to utilize unused frequencies within a carrier’s licensed bands, and use less power than many other types of network.

What Is Over-the-Air? OTA Provisioning Explained

22.12.2020 – Knowledge Hub

OTA provisioning refers more specifically to the process of updating or modifying something wirelessly. In cellular IoT, this most often refers to updating firmware and managing SIM cards.
