Telkomsel, the largest mobile network operator in Indonesia and Huawei announced the successful commercial deployment of CloudAIR 2.0 Solution that enables spectrum cloudification (dynamic spectrum sharing) and channel cloudification.

The implementation of the solution will improve the air interface efficiency and enable operators to have more flexibility to deploy networks and provide a better user experience, said Huawei.

The spectrum cloudification technology realizes the deployment of different Radio Access Technologies (RAT) in the same spectrum. This solution can dynamically allocate and adjust spectrum resources according to the changes of traffic and avoid the legacy RAT to occupy the golden spectrum in in the long term to maximize spectrum efficiency.

Meanwhile, channel cloudification technology combines the advantages of larger downlink bandwidth of high bands and better uplink coverage of low bands. The high band is selected as the uplink at near point and midpoint for capacity, while the low band is selected as the uplink at the cell edge to compensate the coverage limitation of high band.

From the verification in Telkomsel's live network, it is clear that the solution increases the mobile broadband cell edge user experience significantly. The application of spectrum cloudification technology increases LTE user downlink speed throughput by 116% from 50Mbps to 108Mbps. In addition, the implementation of channel cloudification technology improves the carrier aggregation coverage for outdoor areas by 21.4% as well as two to three times user experience improvement for indoor areas.

The solution is the result of Telkomsel and Huawei’s work at the Joint Innovation Center 2.0 (JIC2.0), aimed at reshaping the air interface with the concept of cloudification to efficiently share air interface resources such as spectrum, power and channel. 

Bob Apriawan, Network Director, Telkomsel
Huawei’s CloudAIR 2.0 solution has helped Telkomsel improve spectrum utilization efficiency by 47% and accelerate LTE 20MHz deployment within 1.5 Years. There is a 21.4% improvement for high band carrier aggregation coverage and 2-3 times user experience improvement for the cell edge scenario.

Dr. Peter Zhou, CMO, Huawei's Wireless Solutions 
We are delighted to provide an innovative solution for . Our focus is on improving the efficiency of air interface, enabling Telkomsel to deploy services more flexibly and, of course, enhancing the experience of Telkomsel’s millions of subscribers.
