    Need for the mobile broadband is growing at increasing pace, placing emergent demands on the scarce radio spectrum resources. Licensed Shared Access (LSA) is a new complementary licensing method to traditional exclusive licensing and unlicensed operations for spectrum access that allows current incumbent spectrum users to share their spectrum with additional LSA licensees, such as mobile network operators (MNOs), according to this LSA regulatory framework issued by a National Regulatory Authority. The advantage of LSA with conditions that resemble exclusive licensing is that the rights of both the Incumbent and MNO spectrum users are guaranteed and Quality of Service (QoS) fully supported. This chapter presents the LSA spectrum sharing framework, concept and system architecture based on the recent developments in regulation and standardization. We discuss LSA system concept, stakeholders and their relations in the LSA use cases. Next results of the recent LSA demonstrations and trials are introduced with a focus on indentifying key enabling technologies. Finally, spectrum sharing business model scenarios are shared showing how
    LSA can become an important solution to gain access to new mobile broadband spectrum on time while enabling new innovative business opportunities for existing and new stakeholders.
