Cloud RAN accelerates Chunghwa Telecom’s 5G future

In previous blogs I’ve talked about how Cloud Radio Access Networks (RAN) has been tested and verified globally, ensuring all the same functions can be run as reliably as on a conventional RAN.

Yet that’s just the beginning of the Cloud RAN story. What excites us as a Cloud RAN vendor is the new possibilities the technology opens up, one example being the low latency and high throughput to support new services like augmented reality, virtual reality and ultra-high definition video.

While the revenue-generating possibilities of these glamorous new services are an important reason for operators to adopt the technology, there are many  more benefits. So, what does Cloud RAN mean to leading operators?

Taiwan’s Chunghwa Telecom recently completed a month-long trial of Cloud RAN centralized and distributed (CU/DU) split architecture in its lab. This first Cloud RAN CU/DU trial in Taiwan verified that peak throughput, calls, radio performance and other Nokia AirScale Cloud RAN technology functions provide strong performance.

What does Cloud RAN mean to Chunghwa Telecom

Encouraged by the trial’s success, Dr. Rong-Syh Lin, President of Telecommunication Laboratories at Chunghwa Telecom agrees that, along with its own Mobile Edge Computing technology, Cloud RAN will enable great new applications needing low latency and ultra-broadband.

“Cloud RAN also offers the advantages of centralized and flexible allocation of radio resources, as well as improved spectral efficiency and network capacity. It is an important milestone for Chunghwa Telecom to move towards 5G,” he says. “In addition, the cloud architecture aids the introduction of big data analysis and artificial intelligence, which will bring benefits in the shape of network intelligence and automated management to help improve operational efficiency and quality."

Jason Liu, Head of Market Unit Taiwan, Nokia adds: “We are honored to work with Chunghwa Telecom on the first Cloud RAN network trial in Taiwan, paving the way for the success of 5G in the future. Cloud RAN solution is essential in enabling Nokia 5G Future X network, a more flexible, resilient network with low latency and distributed architecture. It is also capable of providing radio resources allocation quickly and flexibly on service requests, thus preparing for the needs of the future 5G application scenarios.”

At the end of January this year, Chunghwa Telecom has teamed up with the 5G Office of MoEA (Ministry of Economic Affairs), ITRI (Industrial Technology Research Institute) and III (Institute for Information Industry) to form ‘The Taiwan 5G Alliance – Chunghwa Telecom Pilot Team’, which has invited more than 40 institutes and enterprises to join the alliance. Chunghwa Telecom is planning to open its 5G trial network to help establish a 5G industry ecosystem and is aiming for 5G pre-commercialization in 2020.

Further information on commercially available AirScale Cloud BTS

The Nokia Cloud RAN solution based on commercial AirScale and AirFrame platforms won the GTI Innovative Breakthrough in Mobile Technology Award 2018. In April, the AirFrame data center portfolio was extended with the launch of the Nokia AirFrame open edge server, the industry’s first Edge Cloud data center portfolio, to meet the stringent and diverse low-latency data processing demands of Cloud RAN and advanced applications for consumers and industries.
