Converging Telecom Service – Cellular, Wi-Fi, Satellite

The telecom business has traditionally been driven by two main factors: fast, reliable access and the bundling of applications and content to attract users. Because service offerings are often regulated, a converged environment shifts the focus toward controlling access, improving quality of experience (QoE), and delivering value within budget constraints.

Fast and Reliable Universal Connectivity

The fundamental use case remains—providing seamless, high-quality connectivity. User experience tolerances are tight—research shows that in web and social media scenarios, the “3-second rule” is well-known, as users tend to disengage quickly after delays. For requested video streaming, the tolerance period extends slightly, with Enea surveys indicating around 5-6 seconds; however, in reality, the tolerance for high latency or poor connectivity is steadily decreasing.

Seamless Handover

Cellular handover is so seamless that it’s often taken for granted. The challenge arises in mixed connectivity scenarios (cellular, satellite, Wi-Fi), where session continuity, user authentication, and service preferences come into play.

Achieving session continuity involves a cost-benefit analysis. For example, Wi-Fi Calling is conceptually seamless, as traffic is anchored at the same point in the mobile core regardless of whether it flows through Wi-Fi or cellular. However, real-world factors such as device support, carrier implementation, and network conditions can impair session persistence.

The positive news is that most applications, even those that are latency-sensitive like voice and video conferencing, are resilient to brief interruptions. For instance, during a Microsoft Teams video call, switching between Wi-Fi and cellular often results in only a short glitch (< 2 seconds), which users typically accept as seamless.

The vision for convergence is clear: users should be able to start a session in a café via Wi-Fi, seamlessly transition onto a bus with cellular coverage, and continue in rural areas via satellite—all without noticeable disruption. The question is whether users are satisfied with short glitches and if the costs of striving for perfect session continuity are justified, given real-world limitations.

There are also other considerations to take into account in a converged environment:

Prepaid / Postpaid Tiered Access

• Data options tailored to preferred price points.
• Personalized choices and flexibility.
• Incentivized service bundle selections based on user preferences and demographics

Personal Control

• Ability for users to set and modify limits, for instance no TikTok over satellite.
• Family quotas for family members and their devices.
• Sharing quotas through e.g., temporary access codes.
• Bill shock prevention—warnings and controls to prevent background processes like software updates from exceeding metered limits; this functionality already exists for cellular and must extend to metered Wi-Fi and Satellite connections as well.

Partner Media Access

• Content providers like Netflix adapt video quality based on current connection properties.
• If the platform knows the user is on satellite, cellular, or Wi-Fi, it can adjust resolution accordingly.
• This trend is already visible in the US, with expectations of similar adaptations for satellite connections.

Tailored B2B Enterprise Plans in the face of increasing security threats:

• Custom policies enabling and accounting for user access.
• Service-level agreements (SLAs) tailored to different user groups and services.
• Convergence of network slicing, private 5G, and enterprise Wi-Fi networks.
• Advanced analytics for operational insights.

Regulatory Traffic Management

• Enforcing regulations such as the Online Safety Act or Digital Services Act.
• Operational and core network considerations.
• Regulatory scrutiny on traffic management practices.

Lawful Intercept

• Developing a unified lawful interception infrastructure across cellular, Wi-Fi, and satellite networks.
• Routing traffic under investigation to interception points.
• Call/activity audit logging within regulatory boundaries.

Auditing and Operations

• Managing access and network policies through a single, unified control dashboard.
• Providing AI-driven observability and data correlation for improved operational efficiency.

Converged access has the real opportunity to deliver the core telecom use case of fast, reliable, secure and seamless connectivity across rural, urban and maritime environments. Mindful of common considerations learned from cellular technology transitions will enable the business of telecom access to significantly expand.
