Introduction
Bluetooth-enabled devices are ubiquitous in today’s world, but their usage is limited by the relatively short range provided by Bluetooth technology. However, a Seattle-based startup called Hubble Network is looking to change this status quo by launching a satellite network that any Bluetooth-enabled device can connect to, anywhere in the world.
The Problem with Traditional Bluetooth Connectivity
Bluetooth devices are limited by their range, which typically extends only a few meters from the transmitter. This makes it difficult to establish connectivity between devices over long distances, making it impractical for use cases that require global accessibility.
Hubble Network’s Solution
Hubble Network aims to build out a constellation of 300 satellites that can provide real-time updates for any sensor or device outfitted with a Bluetooth Low Energy (BLE) chip. This will enable devices to connect to the network from anywhere in the world, making it possible to use Bluetooth-enabled devices for applications that require global coverage.
Technical Breakthroughs
To make this scale of connectivity possible, Hubble Network has engineered several technical tricks. These include lowering the bitrate, or the amount of data transferred per second, and rethinking the design of the satellite antenna. Instead of sticking a single antenna on the side of a satellite bus, Hubble is using hundreds of antennae per satellite.
The Result
This innovative approach enables each satellite to support millions of connected devices, essentially creating a "huge magnifying glass onto the surface of the earth" that can detect very weak radio signals coming out of Bluetooth chips. This results in a radio signal that can be detected around 1,000 kilometers away – or almost 10 orders of magnitude longer than what can be detected from a Bluetooth chip over terrestrial networks.
Launch Plans
Hubble Network plans to launch an initial batch of four satellites on SpaceX’s Transporter-10 rideshare mission in January 2024. The startup is fully funded through this mission, thanks to a $20 million Series A round that closed recently.
Future Applications
While Hubble Network’s primary focus is on connecting existing Bluetooth devices, the company believes its network will also stimulate the development of new applications that haven’t been possible before. "Eventually, if this network does exist, we think some of our biggest customers haven’t even incorporated yet because they haven’t been able to build these kinds of devices," says Hubble Network’s CEO.
Conclusion
Hubble Network’s innovative approach to Bluetooth connectivity has the potential to revolutionize the way we use Bluetooth-enabled devices. With its satellite network and technical breakthroughs, Hubble is poised to make global connectivity a reality for billions of devices worldwide.
