Space Invaders 🛰️ with Bluetooth 💙 One fun part of my work at The Digital and Intelligence Service (DIS) is learning about cutting-edge tech🪄 & innovators 🧙🏼♂️ behind them. I had the recent pleasure of coffee with Alex Haro , co-founder of Hubble Network whose tech is out of this world 🌌 🟢🟢 Some basics on Bluetooth (BT💙) 🌀 Named after Viking King Harald 'Bluetooth' Gormson, who unified Denmark & Norway in 958, & had a dead blue tooth 😮 🌀 Developed in 1996 by Intel Corporation Ericsson Nokia as a short range wireless protocol to link PC & Mobile. 🌀 BT💙 is ubiquitous 🌏 with ~ 5 billion new devices in 2022. At 2.4 GHz & transmit power of ≤100 mW, its Frequency Hopping Spread Spectrum (FHSS) gives it resilient & relatively high throughput connectivity 🌊 🌀 Two flavors 🍨 Bluetooth Classic mainly for audio streaming 🎶 & Bluetooth Low Energy (BLE) for IoT networks, tracking & positioning 🧭 🟢🟢 Bluetooth for Trackers 📍🌏 🌀 BT💙 is used for tracking devices e.g. for keys 🔑 & kids 👦🏼 🌀 Examples are Apple AirTag Samsung Electronics SmartTag & Tile 🌀 They use BLE to transmit signals, enabling apps on BT💙 enabled phones to detect & locate them within ~60 to 120m 🌀 Multiple phones can form networks to triangulate the tags. But in areas with few devices, tracking becomes challenging. 🟢🟢 This is where Hubble Network’s vision comes in 🫡 🌀It tracks tags from space 🌌 with a constellation of Low Earth Orbit satellites 🛰️ 🌀 Accuracy can be in km with one 🛰️ & within metre with multiple 🛰️ 😎 🌀 Existing BT💙 hardware e.g. tags need only a firmware upgrade 💽 to access this service & seamlessly switch between terrestrial & 🛰️ ❌ The Free Space Path Loss is daunting 😭 ❌ For a 100 mW signal at 2.4 GHz & 500 km away, the signal strength when it reaches the satellite is ~4 x 10^-17 W 😨 Imagine the 🛰️ picking up this weak signal when we struggle to connect our📱& earbuds across the room 😱 But Hubble is serious 🌀 Two satellites 🚀 with SpaceX in Mar 2024 🌀 Its key tech is a unique high-gain antenna on 🛰️ & sophisticated signal processing 🌀 It achieved the 🌏 first BT💙 connection from space in Mar 24 connecting its 🛰️ to a COTS 3.5mm BT💙 chip on 🌏 👏🏼👏🏼 This could transform IoT & more if proven at scale 🌀 Cheap tags & sensors everywhere for pervasive tracking in logistics & environmental monitoring 🌀 You can reverse this for Positioning, Navigation & Timing 🗺️ Bluetooth from LEO 🛰️ is likely more resistant to jamming versus GPS A millennium after their European conquest, the Vikings are now invading space 🌌😎 #space 🔹 I shamelessly asked Alex for a sample to test when ready. Must see to believe 😉 🔹 Alex is a serial founder 😎 who co-founded Life360 that recently acquired Tile 🔹 Hubble is not named after Edwin Hubble. Alex has a clever Easter egg 😀 here 🔹The device is a Samsara ruggedized tracker with Hubble’s tech & 5 years🔋 🔹Thanks to Ahmad Ishaq Ahmed Hnesh for connecting 🙏🏼

TechExplained: Bluetooth Channel Sounding Slightly advanced topic for today. It's a new little specification in the new Bluetooth 6.0 standard which I think is interesting. Bluetooth Channel Sounding is a feature that enables precise distance measurement between Bluetooth devices. Unlike earlier methods relying on signal strength (RSSI), Channel Sounding uses phase-based ranging and round-trip timing. These techniques leverage phase & frequency of radio BLE waves at 2.4GHz to calculate distances with potentially a few tens of centimeter precision even with large 50m+ line of sight ranges. Here’s how it works: one BLE device sends a signal with a known phase and frequency. The second device echoes the signal back, maintaining phase continuity. By comparing phase shifts and factoring in timing, the system calculates the distance between devices. This will effectively give you much better precision than the older RSSI techniques. BLE 5.1 had introduced direction finding in Bluetooth based on the angle of arrival and angle of departure. However, the implementation issue was that you needed multiple antennas on either the transmitter or receiver end. Channel Sounding can work with a single antenna on each side making implementation easier. Why does this matter? Think of the Locate Me feature in your phone or key trackers. With Channel Sounding, the search goes beyond “it’s nearby” to pinpoint exact locations, even in complex environments. The technology also enhances digital keys, ensuring your car or door unlocks only when you’re within a precise range, significantly improving security. It will have applications in indoor navigation, asset tracking, VR controller tracking etc. I very well see Apple ditching UWB tech in their air tags in the future for this tech as airtags do contain an additional BLE chip. Your future phones will definitely have this feature. Exciting times ahead for BLE! If you're curious to dive deeper, a fantastic white paper has recently been published on the official Bluetooth website. It's a great read that keeps the concepts clear and jargon-free, definitely worth checking out! #TechExplained #Advanced #BLE #Wireless #Electronics
