What orbit type is essential for achieving true global coverage, including the poles?

Answer

Low Earth Orbit (LEO) or Medium Earth Orbit (MEO)

To achieve true ubiquity, especially including the poles, the architecture must fundamentally change, often requiring many more satellites in non-geostationary orbits such as LEO or MEO.
