Ericsson’s 5G Radio Dot System: Revolutionizing Indoor Connectivity in Taiwan

The rapid expansion of 5G technology has transformed how we experience connectivity, particularly in densely populated urban environments. While outdoor 5G coverage has seen significant advancements, indoor connectivity remains a challenge—especially in large, complex spaces like shopping malls, stadiums, and transit hubs. Ericsson, a global leader in telecommunications, has been at the forefront of addressing this issue through its innovative 5G Radio Dot System. In Taiwan, where high-speed connectivity is crucial for both consumers and businesses, Ericsson has partnered with local service providers to test and deploy this cutting-edge solution.
Taiwan’s bustling urban centers demand seamless indoor 5G performance, particularly in high-traffic areas. Ericsson’s collaboration with Taiwanese telecom operators, including Far EasTone Telecommunications and Chunghwa Telecom, has demonstrated the potential of the Radio Dot System to revolutionize indoor coverage. From underground shopping malls to packed concert venues, these trials have showcased the system’s ability to deliver high-speed, low-latency connectivity while maintaining energy efficiency.

The Challenge of Indoor 5G Connectivity

Indoor environments pose unique challenges for 5G deployment. Thick walls, interference from other electronic devices, and high user density can degrade signal quality, leading to slower speeds and dropped connections. Traditional solutions, such as Distributed Antenna Systems (DAS), often struggle to provide consistent coverage while remaining cost-effective and energy-efficient.
Ericsson’s 5G Radio Dot System was specifically designed to overcome these obstacles. Unlike conventional DAS, which relies on bulky infrastructure, the Radio Dot System uses compact, scalable radio units that can be easily installed in ceilings or walls. This modular approach ensures flexible deployment, making it ideal for large indoor spaces where signal penetration is difficult.

Proven Performance in Real-World Scenarios

1. High-Speed Connectivity in Taipei City Mall

One of the most compelling demonstrations of the Radio Dot System’s capabilities took place at Taipei City Mall, Taiwan’s largest underground shopping center. With thousands of daily visitors, the mall presented an ideal test environment for high-density 5G performance.
During the trial, the system achieved peak downlink speeds exceeding 1 Gbps, showcasing its ability to handle heavy network traffic. Utilizing the 3.5GHz spectrum and 4×4 MIMO (Multiple Input Multiple Output) technology, the Radio Dot System optimized spectrum efficiency while maintaining strong signal quality. This breakthrough is particularly significant for Taiwan, where consumers and businesses increasingly rely on ultra-fast, reliable connectivity for everything from mobile payments to augmented reality shopping experiences.

2. Energy Efficiency and Sustainability

Beyond speed, the Radio Dot System stands out for its energy efficiency. Compared to traditional active DAS, it reduces power consumption by 45%, translating to lower operational costs and a smaller carbon footprint. This aligns with Taiwan’s broader sustainability goals, where telecom operators are under pressure to reduce energy usage while expanding network capacity.
For property owners and service providers, this efficiency makes the system a cost-effective long-term investment. Shopping malls, airports, and office buildings can deploy the Radio Dot System without worrying about excessive energy bills, making it a win-win for both business and environmental sustainability.

3. Enhanced User Experience in Crowded Venues

Another critical test was conducted at Taipei Dome during a New Year’s Eve concert, where thousands of attendees simultaneously used their smartphones for live streaming and social media. The trial, conducted in partnership with Far EasTone Telecommunications, leveraged 5G Advanced (5G-A) network capabilities and network APIs to create differentiated connectivity clusters.
This approach ensured that high-priority applications (such as emergency services or live broadcasts) received guaranteed bandwidth, while general users still enjoyed smooth connectivity. The results proved that the Radio Dot System can dynamically adapt to network demands, preventing congestion in high-traffic scenarios—a game-changer for event venues and public spaces.

The Future of 5G in Taiwan

Ericsson’s successful trials in Taiwan highlight the Radio Dot System’s readiness for large-scale deployment. As Taiwanese telecom operators continue to expand their 5G networks, this technology offers a scalable, future-proof solution for indoor coverage.
Moreover, Ericsson’s collaboration with Chunghwa Telecom on network slicing—a technology that allows customized virtual networks for different industries—further underscores the system’s versatility. Whether for healthcare, smart manufacturing, or public safety, the ability to tailor connectivity ensures that Taiwan’s 5G infrastructure can support diverse applications.

Conclusion

Ericsson’s 5G Radio Dot System represents a major leap forward in indoor connectivity, addressing the limitations of traditional solutions with speed, efficiency, and adaptability. The successful field tests in Taiwan—from underground malls to packed concert venues—demonstrate its potential to transform how we experience 5G indoors.
As Taiwan continues to push the boundaries of 5G innovation, the Radio Dot System is poised to play a central role in ensuring seamless, high-performance connectivity across the island. With its energy-saving benefits, high-speed capabilities, and dynamic network management, this technology is not just a technical achievement—it’s a foundation for the next generation of smart, connected spaces.
