m installation point of view than a Wi-Fi access point or any other system operating on the 5 GHz unlicensed band currently would require. Especially in an environment where the traffic density is high, LAA is an attractive solution to tap the unused potential of the 5 GHz spectrum. Especially when there is possibility to control what kind of systems are installed, such as in a corporate environment, finding fully empty channels from 5 GHz band will be relatively easy, allowing LTE to reach full potential of the performance. LTE for unlicensed band will rely on the existing LTE core network and will use the existing LTE security and authentication framework thus not requiring any changes in the core network domain. The use of LTE unlicensed together with the licensed band operation (LAA for LTE) allows having a major capacity boost from unlicensed band while still ensuring end-user quality of service regardless of the interference situation in the unlicensed band.
