Mobile internet providers must now reduce interference with weather satellites

The US communications regulator has tightened rules for mobile operations in the 24 GHz band. This means mobile internet providers must reduce unwanted emissions to protect weather satellites from interference.

For years, mobile internet providers could operate in certain frequency bands without strict limits on how much their signals bled into adjacent bands. This bleed-over interfered with weather satellites, making their data less reliable. The new rules mean mobile providers must now invest in better filtering technology or adjust their operations to prevent this interference.
