Speedify Combines Starlink and Intelsat Satellite Internet for Faster Upload and Download Speeds

For network engineers, IT managers, and infrastructure decision-makers, Speedify's Starlink and Intelsat bonding delivers concrete operational value:

• Redundancy without identical failure modes: Starlink and Intelsat fail for different reasons. LEO satellite handoffs, weather attenuation at Starlink's operating frequencies, and orbital congestion do not cause the same disruptions as GEO signal degradation at Intelsat's fixed ground stations. Speedify exploits this difference to maintain a healthy path even when one satellite system is disrupted.
• Combined internet upload and download capacity across both satellite connections: Without bonding software, devices use one satellite connection at a time. With Speedify, both internet connections carry traffic simultaneously. A business bonding a 200 Mbps Starlink connection and a 50 Mbps Intelsat connection can approach 237 Mbps of usable throughput rather than being capped at whichever connection is active at a given moment.
• Latency-aware traffic distribution: Speedify routes interactive, latency-sensitive traffic over Starlink's low-Earth-orbit connection and uses Intelsat's higher-latency GEO connection for background throughput. This is not a static policy: Speedify adjusts distribution in real time based on measured latency, packet loss, and jitter on each connection every few milliseconds.
• Seamless failover with no session interruption: When Starlink drops or degrades, active VoIP calls, video conference sessions, remote desktop connections, and cloud application sessions continue without interruption. Speedify reroutes at the packet level before applications detect a problem. When Starlink recovers, Speedify rebalances automatically.
• Uniform AES-256 encryption across all satellite connections: All traffic bonded by Speedify passes through AES-256-GCM encrypted tunnels using DTLS 1.2. Every packet traveling over Starlink or Intelsat is protected, regardless of which satellite connection carries it. See Speedify's full encryption specifications for detail.
• Centralized policy and monitoring across your team: Speedify Teams provides a single dashboard for managing connection priorities, applying data limits to metered satellite capacity, and monitoring real-time usage across all team devices and locations.

Starlink operates in low-Earth orbit (LEO), with satellites positioned approximately 340 miles above Earth. This results in round-trip latency in the 25 to 60 millisecond range and upload and download speeds of 100 to 300 Mbps under good conditions. Starlink's LEO position makes it well-suited for real-time applications: VoIP, video conferencing, live data transmission, and interactive cloud applications. However, because LEO satellites move relative to the ground, Starlink dishes experience brief micro-outages during satellite handoffs, and signal quality can degrade under heavy rain or snow.

Intelsat operates geostationary (GEO) satellites positioned approximately 22,000 miles above Earth. GEO satellites remain fixed relative to the ground, which means a fixed dish always points at the same satellite. This gives Intelsat consistent, predictable coverage over defined geographic areas, including regions where Starlink availability is limited or where regulatory licensing has not yet been approved. The trade-off is latency: GEO satellite connections carry round-trip latency that typically exceeds 600 milliseconds, which makes them unsuitable as a sole connection for latency-sensitive applications.

Speedify bonds both satellite connections into a single managed internet path. All traffic passes through one Speedify encrypted tunnel. Inside that tunnel, Speedify distributes packets across Starlink, Intelsat, and any additional internet connections, including 4G/5G cellular and wired Ethernet, based on real-time performance measurements. Latency-sensitive packets are preferentially routed over Starlink. When Starlink degrades, Speedify immediately shifts affected traffic to Intelsat. When Starlink recovers, Speedify rebalances across both connections automatically. Your team never manually switches connections, and no active session is interrupted.
