Next generation of radio spectrum management: Licensed shared access for 5G

The comparison between the LSA and the SAS approaches suggests that the LSA regime can be implemented quicker and with less effort than the SAS regime, because of its lower level of technical complexity. Nevertheless, the LSA regime is expected to be overtaken by the SAS regime in the long term, as technology advances. The SAS regime would allow more users to coexist in the same spectrum bands thanks to spectrum sensing techniques.
