Spectrum sharing is an important enabler for future mobile broadband systems to meet the growing end user data traffic needs. Considering spectrum sharing from regulation, business and technology perspectives is the key for the successful development of sharing models that can be deployed in practical systems. This chapter studies recent spectrum sharing concepts from regulatory, business and technology perspectives. We present the European Licensed Shared Access (LSA) spectrum sharing concept covering its regulatory, business, and technical aspects with a focus on the LSA case example of sharing between LTE and incumbent program making and special events (PMSE) services in the 2.3-2.4 GHz band. The LSA evolution including more dynamic sharing toward the US three-tier spectrum sharing model for Citizen Broadband Radio Service (CBRS) based on Spectrum Access System (SAS) is depicted in terms of its ecosystem, business benefits, and technical approaches. Future outlook is given to envisage the development of sharing models for the mobile broadband.
