Speed Comparison - Viasat vs Qianfan (SpaceSail)
Viasat offers 25-150 Mbps. Qianfan (SpaceSail) has not confirmed speed specs.
Latency Comparison - Viasat vs Qianfan (SpaceSail)
Qianfan (SpaceSail) has significantly lower latency at 60-70ms vs Viasat's 500-700ms - roughly 9.2x 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.
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 Qianfan (SpaceSail)
Viasat starts at $69.99/mo. Qianfan (SpaceSail) has not announced consumer pricing - it may be enterprise-only or is still in development.
