Internet Backup Solution Using 5G2B and LEO

Eliminate the risk of disconnection with NetNam's 5G2B and LEO satellite Internet backup solution. Integrating Premium DIA with a 99.99% Uptime commitment ensures business continuity. 

In the digital era, Internet connectivity is no longer just a utility; it is the operational lifeline of any enterprise. However, many organizations still rely on a single main transmission line, leading to significant risks when incidents occur: international fiber optic cable cuts, peak-hour congestion, ISP failures, or natural disasters. The consequences are not only immediate revenue loss but also recovery costs, contract penalties, and long-term reputational damage. 

With over 30 years of experience providing Internet services to enterprises, NetNam deeply understands the pain points caused by network interruptions; from lost transactions and halted operations to reputational risks. Therefore, NetNam has launched a multi-route Internet backup solution combining Premium DIA with 5G for Business (5G2B) and Low Earth Orbit (LEO) satellites. This solution delivers high availability, automatic failover, and infrastructure risk diversification. 

Why Enterprises Need to Upgrade Backup Solutions  

To visualize the cost burden and potential risks, we must categorize the losses businesses face, along with common disconnection scenarios. Understanding these weaknesses is key to designing an effective wireless network backup strategy. 

Consequences of Network Interruption: From Technical Glitches to Strategic Risks  

Instead of being merely a "technical glitch," losing Internet connectivity is now a "Strategic Risk" because it directly threatens business continuity and brand image. 

Direct Financial Damage:  

• Retail/F&B: POS (Point-of-Sale) systems stop working, leading to immediate revenue loss. Every hour of disruption can cost hundreds of millions of VND. 
• E-commerce/Logistics: Delays in order processing, inventory tracking, and delivery increase operational costs and reduce competitiveness. 
• Financial Institutions: Transaction interruptions can lead to contract penalties, compliance risks, and significant monetary losses. 

Indirect & Long-term Damage:  

• Loss of Reputation: Customers lose trust in unstable services, especially when digital experience is a key factor. 
• Recovery Costs: Resources (manpower and time) spent troubleshooting, restoring data, and mitigating consequences. 

Limitations of Traditional Backup Solutions  

Old backup solutions, often relying on a secondary fiber optic line, cannot thoroughly solve the problem: 

• Shared ISP: If both lines come from a single provider, the business remains vulnerable to wide-area incidents (e.g., core network maintenance or system failures). 
• Shared Physical Route: If two fiber cables run through the same physical conduit, they can fail simultaneously due to construction accidents or natural disasters, creating a physical "single point of failure". 
• International Issues: Submarine cable cuts are common issues that a domestic secondary fiber line cannot effectively mitigate. 

To achieve 24/7 connectivity with near-zero downtime, enterprises need a solution that leverages independent technologies and diverse infrastructures. 

Premium DIA with Integrated Backup – Concept and Strategic Benefits  

Deploying Premium DIA with integrated backup helps businesses achieve "Near-Zero Downtime," turning risk management into a competitive advantage in service quality and reliability

Definition and Differentiation: What is Premium DIA with Integrated Redundancy?

Premium DIA (Dedicated Internet Access) is not just a high-bandwidth Internet line. At NetNam, we define Premium DIA as a comprehensive dedicated access service where the main line guarantees symmetric bandwidth, low latency, and superior Service Level Agreements (SLA). 

The breakthrough lies in integrating a multi-technology backup system directly into the solution package. 

Comparison: Premium DIA vs. Standard Market Internet  

In summary, while standard Internet packages provide a "tool," NetNam’s Premium DIA provides a complete "Connectivity Risk Management System". 

Features and Solutions of 5G & LEO

When utilized as a redundancy solution, 5G2B offers significant advantages: rapid deployment without the need for physical cabling infrastructure, high bandwidth, and low latency within optimal coverage zones. Its mobility is particularly well-suited for pop-up stores or temporary operational sites. However, given that 5G relies on coverage and signal quality, enterprises must establish QoS (Quality of Service) agreements with carriers (opting for enterprise-grade plans over consumer SIMs) and consider utilizing eSIMs or multi-carrier SIM configurations to maximize availability.

From a technical perspective, 5G should be integrated via SD-WAN orchestration for automated traffic steering: prioritizing DIA for critical traffic and executing failover to 5G only when necessary. Policy-based routing enables application classification (e.g., prioritizing POS transactions while deferring file backups), while real-time monitoring of the 5G channel's metrics (latency, jitter, packet loss) serves as the prerequisite for a safe and seamless cutover.

LEO (Low Earth Orbit) satellite systems provide Internet connectivity with significantly lower latency than traditional GEO satellites. LEO is particularly valuable for remote sites, logistics warehouses, data collection nodes, or any location lacking terrestrial cable infrastructure or suffering from weak mobile coverage. When integrated with DIA and 5G, LEO establishes an additional redundancy layer, enabling enterprises to mitigate risks associated with vendor concentration or single-infrastructure dependency.

NetNam integrates these technologies via smart routing devices, allowing automatic, near-zero latency switching from fiber to 5G & LEO, maintaining continuous user sessions. 

Strategic Vision: Why Choose This Model?  

Adopting a multi-route, multi-technology backup model is a strategic investment decision, not just a technical cost.  

Meeting High Uptime Requirements & Market Data 

Recent international fiber cable incidents have clearly demonstrated the danger of relying on a single cable route. 

• Increased Adoption: Following consecutive cable cuts, the rate of Vietnamese enterprises investing in high-quality Internet backup systems has risen sharply. 
• High Cost of Downtime: Industry statistics show average damage from system interruptions can reach thousands of dollars per minute for large financial institutions or retail chains. Investing in backup is a far cheaper "insurance cost" than potential losses. 

Real-world Use Cases

Tier 1 enterprises (high uptime requirements) are shifting strongly to this model: 

• Financial Organizations: Ensure smooth transactions for legal compliance and to avoid penalties. 
• Retail Chains & Hospitality: POS, PMS (Property Management System), and payments must run 24/7 to prevent direct revenue loss. 
• Logistics & Operations Centers: Require continuous connection for real-time fleet monitoring and decision-making. 
• Multinational Companies (MNCs): Need stable, reliable connections with global HQs adhering to international standards.
