Licensed Shared Access (LSA) is a regulatory framework that allows multiple users to share the same radio frequency spectrum. This approach helps to optimize the use of limited spectrum resources, enabling more efficient communication services. LSA is particularly useful in areas where demand for wireless connectivity is high. Under LSA, a primary license holder grants access to secondary users under specific conditions. This arrangement ensures that the primary user retains priority while allowing others to utilize the spectrum when it is not in use. LSA promotes innovation and competition in the telecommunications industry.
