ESIM contribute to Sustainable Development Goal 9 (industry, innovation, and infrastructure) by connecting ships, aircraft and land vehicles and ensuring their safety and security and that of their passengers, cargo, and systems.To address the increasing need of ESIM for radio-frequency spectrum, while protecting other and existing radio services, the ITU World Radiocommunication Conference (WRC-19), which took place in Sharm el-Sheikh, Egypt, from 28 October to 22 November 2019, decided on the regulatory and technical conditions under which the frequency bands 17.7‑19.7 GHz (space-to-Earth) and 27.5-29.5 GHz (Earth-to-space) can be used by the three types of ESIMs communicating with geostationary (GSO) space stations in the fixed-satellite service (FSS).The typical data rates currently provided by terminals operating in networks serving ESIMs are around 100 Mbit/s - much higher, or faster, than those provided historically by satellite networks and systems in the mobile-satellite service (MSS), which use lower frequency bands (e.g., the 1.5 GHz, 1.6 GHz, 2.1 GHz, and 2.4 GHz bands).
ESIM systems can provide continuous and consistent service with very wide, or literally global, geographic coverage as ships and aircraft operate at or over almost any location. When ships are at sea or aircraft cross the oceans, they are out of reach of terrestrial networks.
There are currently three types of ESIMs: ESIM on board aircraft (aeronautical ESIM), ESIM on board ships (maritime ESIM) and ESIM on board land vehicles (land ESIM). They provide broadband communications, including Internet services, on platforms in motion.

Earth stations in motion (ESIM) address a complex challenge – how to provide reliable and high-bandwidth connectivity to what are – literally – moving targets.
