IOT

The Internet of Things (IoT) is a network of physical objects, machines, people and other devices that enable connectivity and communications to exchange data for intelligent applications and services. These devices consist of smartphones, tablets, consumer electronics, vehicles, motors and sensors which are all capable of IoT communications.The IoT allows objects to be sensed and controlled remotely across existing network infrastructure, creating opportunities for direct integration between the physical and digital World resulting in improved efficiency, accuracy and economic benefits.

PSS and SSS (LTE Synchronization)

March 31, 2019

 PSS and SSS (LTE Synchronization) After power-up, the UE  tries to obtain time and frequency synchronization with the system. For this, UE needs to detect signals to find out where the frame begins and ends. LTE define two type of synchronization signals: Primary synchronization signal (PSS) Secondary synchronization signal (SSS) UE uses the Synchronization Signals to: […]

Maximum Coupling Loss (MCL) and Maximum Path Loss (MPL)

January 31, 2019

Maximum Coupling Loss has been chosen by 3GPP as the metric to evaluate coverage of a radio access technology. In theory, it can be defined as the maximum loss in the conducted power level that a system can tolerate and still be operational (defined by a minimum acceptable received power level). MCL can be calculated […]
