Chunghwa Telecom and Ericsson achieve record network performance with FDD Massive MIMO Technology

Chunghwa Telecom and Ericsson (NASDAQ: ERIC) achieved record network performance during the 2026 Taipei 101 New Year’s Eve celebration, delivering a seamless user experience at one of the most critical moments of the year. The milestone marks the first commercial deployment of triple-band Frequency Division Duplex (FDD) Massive MIMO (Multiple Input, Multiple Output) radio on a live network in Northeast Asia.

During the New Year’s Eve countdown, hundreds of thousands of people gathered around Taipei 101, placing extreme pressure on the mobile network during peak traffic periods. Deployed in this high-traffic environment, Ericsson’s Massive MIMO series delivered significant improvements in speed and latency, and increased network capacity by three times. This ensured a smooth and reliable user experience during the most critical moment of the celebration.

Chung-Yung Chia, President of Network Technology Group at Chunghwa Telecom, said, “In high-density scenarios such as the Taipei 101 New Year’s Eve Celebration, ensuring stable and high-speed connectivity for optimal user experience is our top priority. With Ericsson’s advanced FDD Massive MIMO technology, we successfully addressed the extreme traffic demands and enhanced the user experience. The result offers a valuable reference for future network deployment and service upgrades.”

Designed for high-capacity sites with demanding uplink requirements, Ericsson AIR 3284, a triple-band FDD Massive MIMO radio, supports this transition by enhancing uplink capacity and coverage on existing sites. In weak-signal conditions, NR uplink throughput was proven to improve, demonstrating how enhanced uplink coverage can deliver more reliable performance and better user experience in dense, high-traffic environments—while helping Communication Service Providers (CSPs) prepare their networks for the next phase of mobile evolution.

David Chou, President of Ericsson Taiwan, said, “We are pleased to work with Chunghwa Telecom to deliver reliable, high-performance connectivity in high-traffic environments. By deploying Massive MIMO across key FDD bands, we enable higher capacity, better spectrum utilization, and improved investment efficiency for our customers. Together, we are advancing network modernization while building a strong foundation for future network evolution.”

Following the successful deployment, Chunghwa Telecom and Ericsson plan to expand their collaboration across additional high-traffic scenarios, including dense urban areas and major event venues. These joint efforts reflect a shared commitment to accelerating mobile network modernization and enabling more intelligent networks that adapt to evolving user demands and support future innovation toward 6G.
