Not 1, not 2, but 64 ways to get mobile broadband

When using everyday electronic products such as printers, gaming consoles and TVs, we don’t usually stop to think of the software that runs them – quietly working away in the background, it’s much less visible than the exciting features in front of us.

Yet it’s no less vital – and one of the major software languages powering these devices, C and its development C++, was invented by Nokia Bell Labs. Being present in so many devices that we have come to rely on, it’s not too much of an exaggeration to say that C and C++ has changed our world.

Fast forward and everyone now wants super high speed mobile broadband that can download 4K and 8K video in a fraction of a second.

5G is the next generation technology promising a completely new kind of experience. It is also promising operators that it will have the capacity to deliver such experiences. Yes, 5G and Industry 4.0 will change our lives, but under the hood making it run and one of the key enablers of 5G is Massive MIMO (Multiple Input and Multiple Output).

Yet again, Nokia Bell Labs is the source of this revolution. And revolution it is - the next step after MIMO and Beamforming, Massive MIMO allows multiple transmit and receive paths. A typical MIMO is a 2 transmit and 2 receive combination at the LTE base station - Massive MIMO uses software to scale this up to 64 transmit and 64 receive and more.

Using a large number of transmit and receive paths allows base stations to deliver high gain to end users, giving increased network capacity. Massive MIMO also enhances typical beamforming, which creates a sharp beam towards the end user.

Why wait when you can start with 4.9G?

You may think we have to wait for 5G to get Massive MIMO, but with Nokia 4.9G technology, we can have it sooner.

In trials and demos with leading operators such as China Mobile and Sprint, we have shown that our Massive MIMO and 3D Beamforming solutions can give users a 5G-like experience - a significant increase in the individual user download and upload speeds,  improved coverage and a five-fold increase in capacity. And using our massive capacity AirScale platform, we achieved Massive MIMO that was most compact, highest in energy efficiency and offering high gains for download as well as upload and a network with most users per cell.

See the Sprint and Nokia Massive MIMO demonstration:

Nokia 4.9G Massive MIMO can start delivering a great 5G-like user experience for urban areas like city centers or hard to reach high rise towers, achieving improved coverage for high-frequency bands without site densification. It can also achieve high spectral efficiency, squeezing every single bit out of available spectrum. The transition to Cloud core already started and transition to Cloud RAN, and to massive MIMO can start in 2017, ahead of any wide 5G deployments.

Massive MIMO will be yet another breakthrough invention that will change our lives.
