Explanation

Cellular (mobile broadband) is the best choice for frequent travelers because it relies on existing cellular towers, providing coverage across wide geographic areas without requiring any fixed infrastructure at the user's location. ISDN requires a physical phone line connection, making it impractical for travel. Satellite requires specialized dish hardware that must be aimed correctly and is not portable. Line-of-sight wireless requires a clear, fixed path between two stationary antennas, making it completely unsuitable for travel. Cellular data (3G/4G/5G) works anywhere there is cell coverage, which is the defining advantage for a mobile user.
