Autonomous logistics corridors traversing transcontinental deserts face severe communications blackouts. This paper details HAPS deployment architectures guaranteeing zero-deadzone coverage.
A single stratospheric platform replaces up to 120 terrestrial cellular towers along remote highway stretches, reducing capital expenditure by 74% while providing superior line-of-sight geometry.
High-altitude field trials confirm an 18 dB link margin in 5.9 GHz bands, easily penetrating sandstorms and moderate cloud covers to reach ground autonomous trucks.
