Chunghwa Telecom shows the way forward
Chunghwa Telecom put energy efficiency to the fore in a recent 5G rollout and were handsomely rewarded when they managed to reduce power consumption by 33 percent on average while achieving excellent uplink and downlink speeds in both stationary and drive tests.
Background
Chunghwa Telecom is Taiwan’s largest service provider, with a 36 percent market share, and can claim around 10.7 million out of the 29.5 million subscriptions in Taiwan. Leading network performance and an excellent user experience continues to be key factors for a thriving business, but energy savings and sustainability have become equally critical topics for both the customer and the Taiwanese authorities.
The challenge
- Upgrade mid-band 5G with a reduction of power consumption and OPEX
- Support the operators’ sustainability goal of a yearly 1% reduction of power consumption
- Enhance user experience and speeds for best video performance
- Safeguard the future of the network
The solution
- Latest generation mid-band Massive MIMO antenna-integrated radios AIR 6419 and AIR 3219
- Centralized RAN with RAN Compute solutions RAN Processor 6651 and Baseband 6631
- Router 6000 and Fronthaul 6000 best performing transport solutions for C-RAN and with lowest power consumption
Alex Chien, President of Network Technology, Chunghwa Telecom, says: "Sustainability has always been at the heart of our business. CHT has been included in Dow Jones Sustainability Emerging Markets Index for 10 years in a row and is being recognized by numerous sustainability awards globally. We believe network modernization is a key enabler for a greener digital infrastructure as the foundation for the societal Net Zero target. Our partnership with Ericsson will accelerate our transformation to a low-carbon future."
David Hammarwall, Acting Head of Product Area Networks, Ericsson, says: "Building a high-performing and energy-efficient 5G network with Chunghwa Telecom is part of our vision for resilient and sustainable future networks. Using our energy-optimized 5G portfolio, we are tackling one of our industry’s biggest challenges – reducing network energy consumption and carbon footprint while scaling up 5G. Our goal is to realize a low-carbon future while accelerating 5G experience."
The result
- The new Massive MIMO portfolio reduced radio site energy consumption by an average of 33%
- It’s possible to increase performance while reducing operational cost
- Centralized RAN can bring additional energy savings, while opening a fast lane to Carrier aggregation and a coverage boost of mid-band Massive MIMO
- Fronthaul 6000 and Router 6000 are key transport tools to build Centralized RAN with low power consumption and high performance
