Speed Comparison - Viasat vs AST SpaceMobile

Viasat offers faster download speeds at 25-150 Mbps compared to AST SpaceMobile's 10-120 Mbps. That is up to 1.3x faster at the high end.

Viasat 25-150 Mbps
AST SpaceMobile 10-120 Mbps

Upload speeds: Viasat 3-10 Mbps vs AST SpaceMobile 2-10 Mbps. Speeds are advertised ranges and vary by location, time of day, and congestion.

Latency Comparison - Viasat vs AST SpaceMobile

AST SpaceMobile has significantly lower latency at 20-40ms vs Viasat's 500-700ms - roughly 20x lower. This is primarily due to LEO vs GEO orbit differences. Viasat's high latency makes real-time activities like gaming and video calls noticeably laggy.

Viasat 500-700ms
AST SpaceMobile 20-40ms

Lower latency is better. Under 80ms is good for gaming. Under 300ms works for video calls. GEO satellites (35,786 km) have 600ms+ latency due to signal travel time. LEO satellites (550 km) achieve 20-60ms.

Pricing Comparison - Viasat vs AST SpaceMobile

Viasat starts at $69.99/mo. AST SpaceMobile has not announced consumer pricing - it may be enterprise-only or is still in development.

Pros & Cons

Viasat

Advantages

  • + No hard data caps on Unleashed plan
  • + No long-term contract on Unleashed plan
  • + ViaSat-3 F2 entering service May 2026 - expected to more than double bandwidth
  • + Large fleet including Inmarsat for aviation/maritime

Limitations

  • - High latency (500ms+) - GEO orbit limitation
  • - Speeds throttled during peak congestion
  • - ViaSat-3 F1 operating at reduced capacity due to antenna issue
  • - Equipment lease fee ($15/mo) on top of service price
  • - Professional installation required

AST SpaceMobile

Advantages

  • + No dish or special equipment - works with existing phones
  • + Partnerships with AT&T, Vodafone, Rakuten
  • + Next-gen BlueBirds support up to 120 Mbps per cell
  • + Game-changer for dead zones and emergency connectivity

Limitations

  • - Beta service not yet publicly available
  • - Only 6 satellites in orbit - coverage is intermittent until 45-60 sats deployed
  • - Lower speeds than dish-based services
  • - Depends entirely on carrier partnerships for consumer access
