Part 12/19:
High altitude platform stations (HAPS) are essentially flying cell towers operating at altitudes of about 20 km, aiming to provide internet connectivity to areas where traditional infrastructure is impractical or impossible. As of 2023, over 2.6 billion people in 100 countries still lack internet access, and HAPS could change that, bringing educational resources, telemedicine, and economic opportunities to previously unconnected communities. HAPS can also be deployed quickly in response to natural disasters, restoring communication when it's needed most. However, keeping these platforms aloft for extended periods requires advanced materials and energy systems, navigating complex international airspace regulations, and addressing potential environmental impacts are ongoing challenges.
