5G Interworking Architecture

In today’s blogpost we will discuss how the interworking architecture of the new 5G system with the existing LTE systems looks like. Inter-working between 4G and 5G will play a very important role in the early deployment of 5G system, which will rely on LTE to be the anchor or underlying system. In the standalone (SA) deployment of 5G, good inter-working with the LTE system to facilitate inter-RAT mobility between the two RATs will be required.

Often, the term wireless, refers to wireless communication. This is a way of transferring information between devices that are not connected with wires. Where is wireless used? Before learning how wireless […]

What is Pathloss

Introduction to pathloss A transmitter generally radiates the signal which has a specific power using an antenna. This signal travels in the environment as an electromagnetic wave and suffers from a phenomenon known as pathloss. This wave isn’t aware of the exact route to the receiver and hence once transmitted propagates in the direction where […]

What is Shadowing?

Shadowing happens, when there is a large object such as a hill or a building that obscures the main signal path between the transmitter and the receiver. This is known as shadowing (shadow-fading), or slow-fading, as it makes the signal level slowly changing with the time (as e.g., the building is “always” there).
