Understanding the 5G NR Standard

The video series explains key concepts behind the 5G New Radio (NR) physical layer standard. You will learn about the requirements and use cases of 5G and the resulting differences between the 5G and LTE standards. Each video offers a deep dive into the technologies and concepts behind 5G NR, including 5G waveforms, frame structure and numerology, downlink and uplink data, Control Resource Sets (CORESETs), demodulation reference symbols (DMRS), synchronization signal blocks (SSB), Cell Search and RACH procedures, and channel estimation.

Submarine Cable Map


Have you ever thought how it is possible to talk to someone on the other side of the planet?
Because of the use of cell phones it is quite common to believe that data / voice communication around the world is done wirelessly but believe me, only a small part is transmitted in this way. A widely used medium for communication between continents and countries is submarine cables.
That’s right, as the name says, they are cables specially designed to withstand underwater conditions and allow connection to tens up to thousands of kilometers of distance between one point and another.
Although it has been a technique applied since the 19th century, the use of these cables is more advantageous than satellite links, since the climate has no impact on signal transmission and the use of optical fibers ensures greater speed and data traffic.


An open-content collaborative mapping project, aimed at marking all geographical objects in the world and providing a useful description of them. It aims to create and maintain a free, complete, multilingual and up-to-date map of the whole world. Wikimapia intends to contain detailed information about every place on Earth.
