Transparency Through Quality of Service Reports for 3G Services

As Singapore continues its digital transformation journey, 3G networks remain a vital part of the nation’s infocomm landscape. While newer technologies like 4G and 5G dominate the conversation, 3G services still play a significant role in supporting a wide range of devices and applications. To ensure these services maintain high standards, the Infocomm Media Development Authority (IMDA) closely monitors their performance through regular Quality of Service (QoS) reports. These reports provide invaluable insights for both consumers and businesses, helping them assess service provider performance and make informed choices.

IMDA’s QoS reports for 3G services track and evaluate key performance indicators (KPIs) that impact user experience. These include:

  • Nationwide Outdoor Service Coverage: This indicator measures the Nationwide Outdoor Service Coverage for the 3G cellular mobile networks.
  • Call Success Rates: The percentage of calls successfully connected without drops or disruptions, ensuring seamless communication.
  • Call Dropout Rates: The frequency of unexpected disconnections during calls, reflecting the network’s stability and robustness.
  • In-Building Service Coverage: The quality and reliability of 3G network coverage within buildings, ensuring users can access consistent connectivity in offices, malls, and other indoor environments.
  • Tunnel Service Coverage: The performance and availability of 3G networks in underground tunnels, such as MRT stations and train routes, critical for commuters relying on uninterrupted service.

These metrics are pivotal for evaluating the reliability of 3G services, particularly for users and businesses that continue to depend on them. Whether it’s for basic voice communication or moderate data use, the detailed QoS reports published by IMDA empower stakeholders to understand network performance and encourage service providers to strive for continuous improvement.

A Continued Focus on Quality

Through its proactive monitoring efforts, IMDA underscores its commitment to enhancing the quality of 3G services. By benchmarking performance against rigorous standards, IMDA ensures that service providers address potential gaps, invest in network infrastructure, and deliver consistent service to their customers.

Even as the industry transitions towards more advanced networks, IMDA’s focus on legacy systems like 3G ensures that no user is left behind. This inclusive approach aligns with Singapore’s vision of building a digitally connected society where every citizen can participate in the opportunities afforded by technology.
