## Summary

Alex Haro, co-founder and CEO of Hubble, explains how his company has built a global tracking network using standard Bluetooth chips communicating directly with low-Earth orbit satellites. Haro details the technical innovation of using digital beamforming and custom waveforms to receive weak 2.4 GHz signals from space, allowing devices to function without GPS or cellular modems. The episode covers Hubble's hybrid terrestrial-satellite architecture, which leverages existing gateways and smartphone apps to provide enterprise-grade, real-time asset tracking and sensor data globally.
