Band 48 operates in the 3550 to 3700 MHz spectrum, utilising a Time Division Duplexing (TDD) configuration. The 3GPP introduced this band in January 2017, formalised under Release 14.1. While its usage outside of the US is relatively sparse, within the US, Band 48 has garnered attention and application.
The band's appeal in the US is attributed to its versatility. It's frequently employed for smaller-scale networks and, notably, for Private LTE networks. The Citizens Broadband Radio Service (CBRS) framework governing this band fosters innovation and flexibility, enabling diverse deployments ranging from industrial automation to enhanced mobile broadband.
