LTE Band 30, labeled as LTE WCS (Wireless Communications Service), occupies a distinct position in the spectrum portfolio. Operating in the 2.3 GHz range, this band was originally designed with a vision for mixed use, encompassing mobile communications and satellite-based services, among others.
AT&T in the United States stands out as the primary operator leveraging this band for LTE services. The choice to deploy on Band 30 stems from 's strategic approach to bolstering its spectrum assets and ensuring more robust mobile broadband service in certain densely populated areas. A unique technical constraint associated with Band 30 is the prohibition of uplink transmission for user equipment (UE) with external vehicle-mounted antennas. This limitation stems from regulatory decisions made to prevent potential interference with adjacent bands and other services.
