Bharti India drives 5G with MIMO technology from Huawei

Bharti India has deployed an enhanced MIMO solution based on Huawei's 5G microwave technology. The MIMO deployment is the largest globally.

Bharti India needed to significantly improve microwave transmission bandwidth with limited frequency resources. Huawei's enhanced MIMO solution fit the bill, as it can resolve bandwidth challenges, reduce tower space requirements by 50% and increase deployment scenarios by 30%.

Huawei's 5G enhanced MIMO technology has been optimised to reduce the Rayleigh distance of line-of-sight MIMO. Compared with standard MIMO solutions, the antenna installation distance is reduced by 70% and multipath interference of long-distance links is resolved so MIMO links work even more reliably. The enhanced MIMO link has been working stably with commercial traffic in Bharti’s live network for over six months.

Adding carrier aggregation (CA) technology to the 1 Gbps enhanced MIMO link will seamlessly upgrade it to a 2 Gbps MIMO link with additional 28 Mhz spectrum. This is made possible by Huawei’s 5G CA outdoor unit (ODU), whose simplified architecture helps to save power consumption by 20% and reduce tower rental fees by 50% while achieving up to 13 km in transmission distance. 

MIMO technology achieves four times the traditional capacity with same spectrum. In this way, telcos can build 5G-ready transport networks without extra spectrum investment.

Perry Yang, President of the Microwave Product Line of Huawei said, "Creating value for customers with innovative technologies is the survival reason for Huawei microwave. Huawei microwave is looking forward to joint innovation with more operators for network development."

MIMO stands for 'multiple-input and multiple-output'. The technology expands the capacity of a radio connection by using multiple antennas.
