Through a software-based update, it will allow 5 million deployed 4G / LTE radio units to migrate seamlessly.

Nokia will allow 4G / LTE radio units to switch to 5G / NR through a software-based update .

This announcement affects several million 4G / LTE radio units, of which one party will be able to migrate instantly. Up to 1 million will be able to benefit from migration capacity right now, a number that should rise to 3.1 million by the end of the year. By 2021, it is expected to have exceeded 5 million.

With the software update, Nokia seeks to offer a transparent and cost-effective spectrum reorganization for its installed base of 359 4G / LTE customers with FDD RF units.

Many of the 5G / NR implementations that exist today have been achieved through TDD cmWave and TDD mmWave. But for the next wave, adjustments will be made to FDD bands.

«This is an important solution,» says Tommi Uitto, president of Mobile Networks at Nokia, «because it will help our customers quickly and efficiently upgrade their existing LTE radios to prepare for 5G, saving them time and money «.

Nokia believes that its solution will save the telecommunications sector tens of billions of euros in engineering and site review.
