ITxPT – IT for public transport

When we hear about automotive electronics as a specific field of electronic engineering, one often wonders what makes it so special.  As regular consumers, we are familiar with consumer electronics and tend to believe that everything (design, manufacturing, and testing) can be replicated in the same manner. However, a multimedia electronic device (or one used to process or transmit data) that is...

eSIM: Two different flavors for the same technology

eSIM (or embedded SIM) technology is destined to replace the traditional SIM cards that you insert in your mobile phones when you buy a new terminal or switch mobile phone operators. The eSIM is an eUICC (Embedded Universal Integrated Circuit Card) chip on the circuit board of an electronic device with a cellular connection. A virtual SIM, which we shall refer to as a mobile operator profile, is...

5G: the expansion of small cells

Future deployments of 5G mobile telephone networks will bring large-scale small-cell roll-outs. A small cell is nothing more than a miniature base station, or low-powered mobile telephone node, that improves a network’s spectral efficiency by allowing the same frequencies to be reused within a geographic area thanks to its limited range (10 meters to a few kilometers). The desire to improve...

Voice over LTE

Voice over LTE

You may not have heard of voice over LTE (VoLTE) technology, but that does not mean you are not using it! Carriers around the world are deploying this technology to get rid of GSM or CDMA-based circuit networks. The first commercial solution was presented in South Korea in August 2012 and most mobile terminals already support it. The main idea is to use a single network (the packet network),...
