Why can a Bluetooth device on Earth successfully connect to a satellite at a distance of 600km?

The Hubble Network has set itself the ambitious goal of creating a global satellite network capable of connecting to any Bluetooth device .

Hubble Network , a Seattle-based startup, has announced a grand ambition to build a global network of satellites capable of linking to every Bluetooth device . Recently, they have proven that this goal is feasible, despite initial doubts from experts. Going forward, Hubble Network plans to expand its network to improve both the capacity and frequency of satellite flights.

Accordingly, this company has just announced a groundbreaking achievement: for the first time in history, a Bluetooth connection has been established directly with space. This is an important step forward in realizing the goal of building a global satellite network that any Bluetooth-enabled device can access.

Earlier this year, Hubble launched its first two satellites into orbit via SpaceX's Transporter-10 shared flight mission, departing from Vandenberg Space Force Base on California's central coast. Since then, the company has succeeded in receiving signals from a simple 3.5mm Bluetooth chip from 600km away.

Hubble Network is a global satellite network capable of linking with all Bluetooth devices.

Despite facing skepticism, especially given the challenges that Bluetooth devices often face when connecting to nearby devices, Hubble Network has proven the criticism wrong. Alex Haro, co-founder and CEO of Hubble Network, emphasized: "Demonstrating the ability to send signals from Bluetooth chips and receive them from space up to 600 km away opens a new era for countless possibilities".

According to the company, connecting any popular Bluetooth device to Hubble's satellite network via a software update, even without a cellular signal, can provide global coverage at Battery consumption is reduced by 20 times and operating costs are 50 times lower. This opens up unlimited development possibilities for applications that use existing, energy-efficient and low-cost sensors without the need for space-specific hardware.

Hubble was founded in 2021 by Haro, co-founder of Life360, along with Ben Wild, founder of Iotera, and John Kim, an aerospace engineer. When the idea of ​​connecting a Bluetooth chip to a satellite was initially proposed, Haro rejected it as too crazy, especially based on his previous experience trying to develop a GPS watch. for children. However, solving this challenge has finally become too compelling, especially as existing traditional and satellite networks often fail, with poor coverage in remote areas, excessive energy consumption and high operating costs globally.
