IoT, for a laymen, is a futuristic system where you can control almost everything – from TV to refrigerator, from air-cooling to coffee machine – with your smartphone.

The trial, conducted in Paris from November 2015 to February 2016, was done for low-cost, low-complexity devices and enhanced network capabilities for cellular IoT.

The trial demonstrated improved indoor coverage and showed that investments could be optimised through new software deployment on top of existing cellular networks.

"We are pleased with the results reached during the trial. EC-GSM-IoT is a promising technology offering new opportunities for massive IoT based on 3GPP standard evolutions," added Arun Bansal, head of business unit radio, Ericsson. EC-GSM-IoT (formerly EC-EGPRS) is a new technology that enables new capabilities of existing cellular networks for LPWA (Low Power Wide Area) IoT applications.

Cellular networks optimised for IoT will be operational in 2017. EC-GSM-IoT is set to be demonstrated at the ongoing three-day Mobile World Congress (MWC) in Barcelona, Spain, that began yesterday.
