Largest DSR technology and MIMO deployed in India by Nokia and Vodafone Idea

Telecom companies Nokia and Vodafone Idea on Wednesday announced that they have successfully completed the first phase of the world’s largest deployment of Dynamic Spectrum Refarming (DSR) technology in India, along with the deployment of the country’s biggest massive Multiple Input Multiple Output (mMIMO) installation.

As per a statement published on Nokia’s website, the DSR technology has been deployed across major cities in the country enabling Vodafone Idea to enhance user experience with optimal use of its spectrum assets. It will also allow service providers to dynamically share spectrum across different technologies according to the traffic demand.

The statement further added that Nokia has deployed more than 5,500 TD-LTE mMIMO cells in the 2500 Mhz spectrum band in eight service areas – Kolkata, Mumbai, Haryana, Gujarat, UP (East and West), Andhra Pradesh and Rest of Bengal in compliance with the Single Radio Access Network (SRAN) contract.

Speaking over the development, Vishant Vora, Vodafone Idea’s Chief Technology Officer, said: “Dynamic spectrum refarming provides us with more network capacity and data speed to enable us to deliver best-in-class network experience to our subscribers. Vodafone Idea was the first one to trial the DSR.”

Nokia India head Sanjay Malik said that the deployment of DSR and mMIMO will help Vodafone Idea enhance network capacity and improve the experience for their customers. Notably, DSR and mMIMO technology also enable networks to prepare for transition towards 5G technology.

In recent years, India has witnessed a huge surge in data usage with significant rise in downloads and uploads per user across all major cities. In March, the internet peak traffic saw a 40% rise, as per ‘State of Internet Traffic Trend’ report by ACT Fibernet. A report by the Internet and Mobile Association of India (IAMAI) states that currently there are almost 504 million active Internet users in the country. Furthermore, the time spent on the World Wide Web continues to remain higher in urban sector of India as compared to rural India, with more than 60% of active Internet population being daily users.

Meanwhile, 5G networks are expected to be rolled out in selected circles of India by mid-2021 after some delays in the process due to unprecedented reasons. 5G will potentially be offering low latency with better stability in network connections and faster data speeds. However, the Cellular Operators Association of India (COAI) has maintained that prices for 5G spectrum in India will be comparatively higher than the international average.
