Throughout the recent history of telecommunications, efforts have been made to reduce latency for multiple reasons . At first it was sought that the calls were as fluid as possible. But it was with mobile Internet connections that this latency began to matter. Using any mobile application that worked in real time required a reduction in delay. However, it is with 5G that it has managed to reduce latency to a minimum that allows new applications beyond mobile phones. This factor is one of the great advantages that are commonly associated with the new generation of networks.
The other two are enhanced mobile broadband, which will dramatically increase speeds, and much higher density, which will enable massive machine-to-machine communications. When we talk about latency, we focus on the URLLC.ultra reliable low latency photo editor communications. application block, which is also usually combined into a subgroup called mission critical communications.MMC., which require extreme reliability , points out Portola, who gives some examples to understand the criticality of having a low latency.

He talks about the so-called health, with applications such as tele diagnosis or tele rehabilitation. But expression is essential is in remote surgery. In this case , the operations are carried out by robots., who follow the orders of a doctor who could be miles away. The reaction times have to be in the order of a millisecond, for a correct surgery. In the industrial field, minimal latency is also necessary, in order for new applications to thrive. Smart factories are implemented through real-time control of each of the production lines.
