Verizon, U.S. Cellular push for 28 GHz protections

A lot of industry folks may think of the embedded subscriber identity module, or eSIM, when the term comes up. But there’s a similar sounding acronym – ESIM – that has an entirely different meaning for wireless networks.

In this case, ESIMs refer to earth stations in motion, and according to the FCC, they offer the potential to vastly improve connectivity for Americans on the move – when they presumably start moving again by land, sea and air, en masse, after the pandemic.     

In May, the FCC expanded the frequency bands available to ESIMs, which are part of the latest and greatest satellite systems currently being deployed. The FCC said it was advancing regulatory consistency between ESIM communication with fixed satellite service systems in geostationary satellite orbit (GEO) and those in non-geostationary satellite orbit (NGSO).
