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 different services to operate without causing interference to one another. LSA is particularly useful in areas where demand for wireless communication is high. Under LSA, a primary user, often a government or commercial entity, holds a license for a specific frequency band. Secondary users can then obtain permission to access this spectrum under certain conditions, ensuring efficient and flexible use of the radio frequency spectrum while maintaining quality of service for all users.
