eSIM vs. Nano SIM Form Factors: What’s the Difference?

22.08.2022 When choosing a SIM card for your cellular device, size matters. Smaller SIM cards take up less space, freeing manufacturers to build smaller devices and add additional components—which is especially valuable in Internet of Things (IoT) applications. Depending on how and where your device will be used, it may also be important to have a more durable SIM card that can handle extreme temperatures and conditions like corrosion and vibrations.

What Is a TAC Number? Type Allocation Codes Explained

26.07.2022 – Identification Numbers

TAC numbers help cellular networks recognize devices that are approved to access network infrastructure. While it doesn’t identify individual devices (the IMEI number does this) or individual SIMs (that’s the ICCID number), it communicates the make and model and confirms that it meets regional standards and specifications.

What Is C-V2X? Cellular Vehicle-to-Everything Explained

15.06.2022 – Cellular IoT

C-V2X is one of the main ways IoT is being used in transportation. It utilizes cellular IoT to enable vehicles to understand and react to their environment in real time. While perhaps the most obvious application is that it enhances automation in driverless cars, it also improves the information drivers have at their fingertips, particularly when it comes to navigation and visibility, and it can simplify toll and parking systems.

What Is Transport Layer Security (TLS)?

30.03.2022 – Protocols

As the name implies, Transport Layer Security is a protocol that gets implemented on the transport layer of a network to encrypt data transmitted via HTTP, FTP, XMPP, etc. TLS is typically implemented in conjunction with protocols like Transmission Control Protocol (TCP), which prioritizes accuracy over speed. However, in some cases it can be used with connection less protocols like User Datagram Protocol (UDP) - then using a slight variant called DTLS.
