B75 (1500 MHz SDL)

Band 75, denoted as the DL 1500+ SDLSDL: A radio communication strategy primarily used in 4G LTE and 5G NR systems where additional spectrum is allocated exclusively for downlink (base station to user equipment) communication. This method is particularly useful in situations where there is asymmetrical traffic demand, typically with a…, targets the European market and operates in the higher end of the 1.5 GHz range. Ratified by 3GPP in Release 15, this band primarily functions as a Supplemental Downlink (SDL), enhancing downlink capacity without corresponding uplink counterparts. It complements primary carrier bands by augmenting downlink data rates, especially crucial in regions or scenarios where downlink data consumption is markedly higher. Given its design, Band 75 is poised to benefit European operators in urban settings where data-rich applications dominate the usage landscape.
