Uusiteknologia 2/2019 published

Uusiteknologia.fi is a Finnish language electronics and technology professionals magazine.

In the newest issue have written articles on many high tech topics (text in Finnish with short introduction in English). The new number has been published as an electronic magazine that looks like a regular printed magazine.

I have written to two articles to this newest issue. The first article is about eSIM technology and second is about IoT security.

5G and IoT will use eSIM article tells tht classic plastic SIM card hardly disappears very suddenly, though eSIM is becoming more common. In some devices there can be both options built-in: eSIM is integrated into device and there is also option to install a separate SIM card to the device.

One eSIM chip embedded inside the device (smart phone, tablet or IoT) typically contains one or several carrier profiles, bootstrap code and network switching and a SIM applet for controlling which carrier profile to use. An eSIM with megabyte memory size can be used to store up to ten operator profiles.

The eSIM chips are commonly available with 132 kilobytes to two megabytes memory sizes.

The SIM card is renewing again when 5G services are coming up. ETSI and 3GPP have defined the needed UICC configurations. A 5G SIM card can be removable SIM, M2M-SIM or eSIM. Besides physical format, telecommunication companies have to consider three different types 5G SIM card options: “transitional”, “recommended” and “low power”. Low Power SIM is designed specially designed for the Internet of Things devices. It contains most of the recommended SIM card features, but some privacy features are left off.

Safer IoT with new technologies tells that the new Internet of Things applications will place great demands on micro-controllers in the near future.
The Internet of Things market will grow in the next few years. By 2020, there are estimated to be 20-30 billion networked devices in the world. At the same time, the security requirements for IoT devices growth.

In many cases previous micro-controller generations cannot meet all the new security demands by themselves, so new hardware
solutions and smarter code are ABI Research has predicted thatthe market for secure micro-controllers will grow to $ 1.2 billion over the next couple of years.

Safer IoT with new technologies article take a look at some examples of embedded solutions for IoT applications and how they have implemented security into their solutions. The included examples illustrate how things are handled with security-enabled micro-controllers, single board computers, and cloud services.

    I’m interested in new technologies not so long ago and have never heard of eSIM. It would be interesting to know how it works. It sounds pretty interesting. Perhaps I should write about it on my blog. Despite the fact that I do not like to write and always use https://an-essay.com/business in this situation, I wanted to find more information and share it.
