Blue Danube Systems, a provider of mobile wireless access solutions that significantly and cost-effectively increase network capacity, has announced its first Coherent Massive MIMO solution for TDD networks, the company said.
Building on the success of its FDD solutions which have delivered 2X to 3X capacity increase through simple retrofit on existing cell sites, Blue Danube´s TDD solution is expected to deliver similar performance gains that have not been possible to date in mobile environments.
Blue Danube´s approach to Massive MIMO starts by assuring RF array coherency which, in conjunction with digital processing, uniquely enables the definition, placement and dynamic coordination of high precision beams. These beams can be software controlled to direct RF energy towards high user-density areas, while minimizing adjacent sector interference, to improve overall network performance. Blue Danube´s FDD systems have been deployed by five operators worldwide and have been in commercial network operation in North America since 2016 serving thousands of users and carrying hundreds of gigabytes of data traffic daily.
With the addition of support for 3.5 GHz (3GPP Band 42, Band 43, Band 48) and 2.5 GHz (3GPP Band 38, Band 40, Band 41), network operators around the world can realize the benefits of true 3D beamforming and Massive MIMO in sub-6 GHz TDD spectrum. Blue Danube is partnering with CBRS equipment vendors to deliver an end to end beamforming solution in Q1´2020.
