Bringing bandwidth when and where it's needed most

The ViaSat-3 constellation is designed to move capacity to meet demand where it's at

Dynamic bandwidth allocation

A "beam" describes  the targeting field of a satellite signal. It's aimed  at a specific area on the ground, moving data back and forth using radio spectrum. 


A satellite's total bandwidth — or capacity — is shared across all of its beams. To get the highest productivity out of a satellite, it's important that the bandwidth is available in areas where demand is highest.


Rather than having bandwidth fixed to beams, the ViaSat-3 constellation is designed to move capacity between beams to bring bandwidth when and where it's needed most — what we call dynamic bandwidth allocation. By anticipating increases in demand throughout the world and move capacity to meet them — giving us the ability to meet dynamic and shifting market demands,  help militaries and governments withstand and recover from stressors, better serve our business and residential customers, and provide superior bandwidth economics.

What's exciting about the ViaSat-3 constellation's ability to dynamically allocate bandwidth?

The enormous capacity of ViaSat-3 isn't worth nearly as much if it’s stranded in areas where there's no demand. So having the flexibility to move the capacity around means all of it is useful.

I think we've redefined what people think space is capable of — we can densify bandwidth in places or geographic regions where people are, where the businesses are, where boats and planes and all of our government customers are.

It's not about how much capacity you have, it's how much capacity you are putting in places where they need it — for us to be able to put as much bandwidth as possible over areas where there is high demand is going be a competitive edge.

When one of our airline customers has 50 jets on the ground, they all want to stay connected — and they have 100 people on each jet. Our ability to move bandwidth around and service those dense spots is a game changer.

What’s revolutionary about ViaSat-3 is having approximately a terabyte of capacity — and then being able to put that wherever it's needed.

If there's no demand at one location, you can move that capacity —and likewise, you can move it back just as seamlessly. That’s very, very powerful.
