Understanding the Satellite Internet Landscape: Amazon Leo vs Starlink

What is Amazon Leo?

Let’s start by addressing a common misunderstanding. Amazon Leo is not affiliated with Jeff Bezos’ Blue Origin. This is Amazon’s own project. It aims to bring fast and reliable satellite internet to locations all over the world.

Most probably Starlink’s biggest competitor, Amazon Leo has some clearly defined goals. Here’s Amazon Leo at a glance from what we know so far:

• Planned Satellite Constellation: Over 3,000 satellites (3,232 satellites to be exact)
• Primary Goal: Provide affordable, high-speed internet globally
• Satellite deployment date: early 2025
• Service roll out date: 2025

Leo vs Starlink, the Technical Battleground: Satellite Deployment and Performance

Both Starlink and Amazon Leo will have similar main infrastructure elements: the satellites, the ground antennas and the satellite dishes. Both will use Low Earth Orbit (LEO) satellites.

When comparing Leo vs Starlink’s satellite constellations, one can see that Starlink clearly has more satellites planned and they orbit at a different altitude:

Starlink:

• Current satellite count: Over 6,000
• Orbital altitude: Approximately 400 kilometers

Amazon Leo:

• Planned satellite count: More than 3,000
• Orbital altitude: Around 500 kilometers

One of the differentiators of Amazon Leo lies in its orbital strategy. Their satellites, orbiting 100 kilometers above Starlink’s, expand their geographical reach. This higher altitude grants each unit a broader coverage area. But, this comes with a critical engineering challenge.

Radio wave propagation follows an inverse squared law. Signal strength diminishes exponentially with distance. Leo satellites orbit higher, resulting in a 40% loss in signal power compared to Starlink’s lower-altitude network. This elevation difference impacts transmission strength significantly.

To counteract reduced signal strength, Leo plans to use slightly larger antennas. By increasing antenna size by roughly 20%, they can restore signal performance.

Orbital Considerations: Low Earth vs. Geosynchronous

How do traditional satellite networks differ from Starlink and Amazon Leo? Currently there are 3 main orbits that can hold satellites:

• Low Earth Orbit (LEO) – 300 – 1,500 km, closest orbit to Earth
• Medium Earth Orbit (MEO) – 7,000 – 20,000 km
• Geostationary Orbit (GEO) – 35,786 km – a satellite in this orbit revolves around the Earth at a constant speed, so it appears to be in a fixed position in the sky.

As most public communication satellites are deployed in LEO and GEO, here’s how these compare:

Starlink, Amazon Leo: LEO Satellites

• Dramatically lower latency (20-40 ms)
• Higher bandwidth potential
• More responsive for real-time applications
• Lower power transmission requirements

Other providers: GEO Satellites

• Extreme latency (500+ ms)
• Restricted bandwidth
• Requires large, fixed directional dishes
• Less suitable for modern internet applications

MIMO Antenna Technology: Must Have for Starlink and Leo

Both Starlink and Leo systems leverage Multiple Input, Multiple Output (MIMO) antenna technology. This represents a quantum leap from traditional satellite communication methods.

How MIMO antennas help communications:

• They replace single large dish with multiple smaller, omnidirectional antennas
• Typically arranged in rows and columns (Starlink uses 64 antennas)
• Sophisticated software combines signals, creating a “virtual” directional antenna
• Enables dynamic tracking of moving satellites in real-time

These systems will calculate and compensate signal travel time differences from the satellites across multiple small antennas. The user gets a seamless, high-performance communication matrix, which results in better performance.

Amazon Leo vs Starlink: Speedify – Another Must Have for Satellite Redundancy

Speedify‘s channel bonding technology can be used alongside Leo and Starlink networks. Users can get a more reliable internet connection especially during satellite transitions.

Starlink currently experiences synchronized satellite switches every 15 seconds. These transitions can cause brief connectivity interruptions. Speedify can provide seamless failover with both Leo and Starlink connections.

Speedify can combine a satellite connection with an existing DSL, cable, tethered phone or another broadband internet. This way, internet would be still available even during those satellite switches.

Better yet, Speedify can also combine Starlink AND Amazon Leo connections together. Having two satellite connections used together with Speedify will definitely get you that “always online” award so valuable when live streaming or being on a video call.

Amazon Leo – Pricing and Plans and How They Compare to Existing Starlink Plans

Amazon Leo are developing 3 distinct performance tiers to address various market needs:

Ultra Compact Model (direct competitor for Starlink Mini)

• 7-inch square design customer terminal
• Maximum Speed: 100 Mbps
• Ideal for mobile and lightweight applications
• Designed for maximum portability and accessibility

Standard Model (direct competitor for Starlink for Homes)

• 11-inches square design customer terminal
• Maximum Speed: 400 Mbps
• Balanced performance for residential and small business use
• Cost of production: $400 or less

High-Bandwidth Model (direct competitor for Starlink for Businesses)

• 19×30 inches rectangular design terminal
• Maximum Speed: 1 Gbps
• Designed for high-bandwidth professional environments
• Targeting demanding business and institutional users

While Starlink currently leads in deployment of its solution, Leo’s strategic approach and Amazon’s resources position it as a formidable competitor. This competition offers quicker, more dependable, and more accessible internet connectivity. Both businesses and consumers will benefit from this, especially in areas with poor internet coverage. And for those who need uninterrupted connectivity, there’s always Speedify to use together with your satellite internet.
