Why Embedded Solutions Remain Key in Futur IFC Architecture ?

Connectivity in the sky is no longer luxury

Today, inflight connectivity is no longer luxury, it's a baseline expectation. From digital natives to millennials and beyond, passengers increasingly expect seamless internet access from gate to gate, whether they’re streaming entertainment, staying connected with others, or working mid-flight.

In a world driven by fast-evolving technologies, from AI and robotics to satellite mega-constellations, it is obvious that we also expect a perfect connection in the sky.

That’s the challenge Internet Service Providers (ISPs) like Starlink, OneWeb, Viasat, Iridium, or Intelsat are taking up. But delivering high-speed, reliable inflight internet comes with significant technical and operational complexities.

The complexities behind inflight connectivity (IFC)

By 2030, it’s expected that over 50% of commercial aircraft will be connected, with full adoption not far behind. However, getting a plane connected is no small feat. It involves:

• Installing onboard systems like modems and servers
• Selecting the right ISP based on the aircraft’s routes and expected usage
• Choosing between satellite connectivity (GEO, LEO) or air-to-ground networks depending on geography routes
• Managing a complex network of integration partners
  
  

On top of that, the cost of installing antennas and maintaining satellite bandwidth is substantial. It can vary significantly depending on the technology selected (GEO, LEO, or ATG), the size of the aircraft, and the level of integration required. On average, a standard satellite-based connectivity system costs around $300,000 to $500,000 per aircraft. This estimate includes the antenna (radome, antenna assembly, and mounting hardware), modems and onboard networking equipment, as well as installation and certification costs.

In addition to hardware costs, airlines must account for ongoing service fees, which depend on bandwidth usage, coverage zones, and service providers. These typically range from $3,000 to $10,000+ per aircraft per month.

Moreover, even with a fully deployed connectivity system, seamless inflight performance is not always guaranteed. Relying exclusively on a cloud-based model introduces several challenges:

• Satellite congestion: With over 14,000 commercial flights in the sky at any moment, network saturation is a growing challenge that can compromise service quality.
  
  
• Latency: While GEO satellites offer a more cost-effective solution, they come with significant drawbacks, including higher latency and increased risk of service interruption, making them less suited for real-time passenger connection expectations.
  
  
• Coverage gaps: LEO constellations are still in deployment and not yet globally consistent. For long-haul routes such as New York - Hanoi, ensuring uninterrupted connectivity requires multiple satellite handovers and providers, making implementation more complex and costly.

A fully cloud-based, latency-free, and interruption-free IFC experience may sound like the ideal, but in reality, it comes with significant technical and financial hurdles, investments that not all airlines are ready to make. Ultimately, what truly matters is delivering a reliable, frustration-free digital experience that reflects real usage, remains cost-effective, and meets passenger expectations with consistency.

A smarter and cost-effective way forward: the hybrid IFC model

The hybrid connectivity model is emerging as a smarter, more cost-efficient approach for airlines. Instead of relying entirely on satellite bandwidth, it strategically combines cloud-based services and embedded systems to deliver a seamless passenger experience, while optimizing costs and performance.

‍

In this model, bandwidth is preserved for high-value or real-time use cases (such as messaging, flight tracking, or live streaming), while non-critical services like movies, press, or shopping catalogs are preloaded and hosted locally.

This not only improves service continuity during all phases of the flight (even in areas with poor coverage), but also reduces network load and enables airlines to better manage their costs, while meeting passenger expectations.

Key benefits of a hybrid model

• Bandwidth optimization: Transmit only essential data; preload and cache high-demand content locally.
• Improved passenger experience: Deliver smooth service even during temporary satellite disruptions
• Cost efficiency: Reduce bandwidth usage and lower operating expenses.
• Tailored experiences: Offer a platform that reflects the airline's brand and 
• Revenue opportunities: Enable advertising, premium content sales, or loyalty program integration.

‍

To succeed in the era of connected travel, airlines must implement inflight connectivity solutions that align with specific operational requirements, striking the right balance between passenger experience, network performance, and cost-efficiency. This requires a strategic approach to system architecture and service selection, ensuring enhanced digital capabilities without compromising budget constraints.
