As household Internet use in Vietnam becomes more immersive and interactive, a 200 Mbps connection is increasingly insufficient to support seamless digital activity across multiple devices. A typical evening can involve 4K TV streaming, children’s online learning and video viewing, and a parent livestreaming sales, while AI-powered cameras and smart devices operate continuously. In this environment, bandwidth is no longer just a technical comparison—it becomes a necessary requirement to maintain stable real-time performance.
Not long ago, 200 Mbps was considered enough for most households. Today, simultaneous use has expanded from passive viewing to real-time interaction and multi-device scenarios. As a result, bandwidth is beginning to act as a bottleneck in Vietnamese homes, particularly during peak usage periods when multiple users and devices compete for capacity.
Upgrading to 400 Mbps is presented as more than a simple speed increase. It is intended to address the practical challenge of multi-device use by enabling household members to use the Internet simultaneously without interfering with one another. The article states that 10 to 15 devices can operate at once while still supporting smooth 4K/8K video, online meetings, remote work, and livestreaming without interruptions during peak times.
It also frames 400 Mbps as a way to restore Internet access to the role of stable infrastructure—so that users experience fewer disruptions and can “barely notice its presence” because services run smoothly.
The article positions Viettel not only as an Internet service provider, but as a company building a digital living space supported by an ecosystem of technologies. It highlights several components intended to improve in-home connectivity and performance:
The article compares Internet access to essential utilities such as electricity and water, arguing that it has become a core infrastructure for daily life. As usage grows, upgrading infrastructure is described as necessary to prevent work interruptions, keep learning uninterrupted, and avoid disruptions to entertainment.
It further emphasizes that a smooth user experience depends not only on bandwidth speed, but also on physical network infrastructure and a 24/7 technically proficient workforce. It cites wide optical fiber coverage and core technology leadership as factors supporting the deployment of 400 Mbps to households.
By enabling stable connectivity during periods of high demand, the article argues that 400 Mbps Internet can support ongoing digital activities at home and help strengthen the broader digital economy and digital society in daily life.
Premium gym chains are entering a “golden era” that is ending or already in decline, as rising operating costs collide with shifting consumer preferences toward more flexible, community-based ways to exercise. Long-term memberships are shrinking, margins are pressured by higher rents and facility expenses, and competition from smaller, more personalized…
