LTE Band 35 operates in the 1.9 GHz spectrum and is specifically configured for Time Division Duplexing (TDD), where both uplink and downlink communications are conducted within the same frequency range, separated by time slots. Given its position within the 1.9 GHz range, Band 35 falls into the broader category of PCS (Personal Communications Service) bands, which have historically been used for various communication services.
However, the TDD configuration of Band 35 sets it apart from other PCS bands, which are typically FDD. The use of TDD allows for flexible bandwidth allocation, making it suitable for scenarios where uplink and downlink traffic demands aren't symmetric. Despite the technical benefits offered by the TDD configuration, Band 35's adoption is limited.
