Documents show Alphabet is testing solar-powered internet drones that use millimeter-wave transmissions to deliver data at speeds up to 40 times faster than 4G
Project Skybender: Google's secretive 5G internet drone tests revealed — Trials at New Mexico's Spaceport Authority are using …
Context & Ripple Effects
Skybender is the third leg of Google's build-your-own-connectivity push. Sundar Pichai had already teased details of a U.S. mobile network 'in the coming months' earlier in 2015, and Google secured high-altitude test rights for its Project Wing delivery drones through its NASA relationship. The newly revealed trials at New Mexico's Spaceport Authority extend that playbook from delivery aircraft to the transmission layer itself: solar-powered drones beaming millimeter-wave signals rated up to 40 times faster than 4G.
It also puts Alphabet head-to-head with Facebook on the identical architecture. Facebook completed a full-scale Aquila prototype with a laser transmitting at 10 gigabits per second in mid-2015, so both companies are now betting that the next billion users get online via high-altitude solar aircraft carrying very-high-bandwidth links rather than towers and cable.
First-order effects
- Alphabet gains a dedicated testbed at the Spaceport Authority for answering the core technical question — whether millimeter-wave transmissions, which degrade sharply over distance and weather, can deliver those speeds from an airborne platform.
Second-order effects
- Facebook's Aquila program now competes directly with a rival pursuing the same solar-drone-plus-high-bandwidth-link design, raising the stakes on which company proves aerial backhaul first and sets the reference architecture.
- The trials add pressure on regulators to open high-frequency spectrum and airspace for commercial aerial use — a path Google has already smoothed once by leaning on its NASA partnership to fly Wing over private land.
Third-order effects
- If the pattern holds, internet delivery starts consolidating around vertically integrated platforms that own the physical layer — aircraft, lasers, private networks — instead of renting capacity from national carriers, with Pichai's teased mobile network as the terrestrial counterpart to the aerial play.
- That Alphabet's X lab was still unveiling over-the-air transmission hardware nearly a decade later — the Taara silicon photonic chip that moves high-speed data through the air with light — indicates these companies treat free-space data transmission as a long-horizon capability worth iterating on regardless of which individual vehicle carries it.
The trend: Major platforms are shifting from renting connectivity off carriers to building the physical layer themselves — drones, lasers, and private networks aimed at the next wave of users.
