B29 (700 MHz SDL)

LTE Band 29 operates within the 700 MHz range and is unique due to its use solely for Supplemental Downlink (SDL). This means it's dedicated exclusively to downlink transmissions, enhancing data capacity in areas with asymmetrical traffic demands where downlink data requirements outweigh the uplink. Given its sub-1 GHz nature, it provides robust propagation benefits, facilitating improved coverage. Its deployment complements primary LTE bands to address the increasing downlink-centric demands observed in modern mobile broadband usage.
