Duration: 
60 Minutes

In the coming years, telecommunications providers face the daunting challenge of increasing data rates while also expanding network capacity by orders of magnitude. High channel count MIMO technologies such as Massive MIMO offer unique benefits that can address these concerns and enable 5G networks. To move Massive MIMO from theory to reality, however, advanced hardware must be combined with challenging signal processing.

In this webinar, we will go over the creation of the world’s first real-time Massive MIMO system at Lund University, Sweden. This successful deployment produced a host of field trial results, but also revealed new challenges in Massive MIMO development. We will cover lessons learned from the Lund system while also diving deep into the signal processing used, including reciprocity calibration, MIMO precoding, and MIMO decoding. Finally, we will discuss the future of Massive MIMO research and standardization. Join us to learn how you can begin building your own Massive MIMO testbed to tackle these challenges.
