Optimization of Authorised/Licensed Shared Access resources

The expected increase of the traffic volume in mobile broadband networks and the upcoming spectrum scarcity, require an optimization of the usage of the spectrum. One of the solutions is Authorised/Licensed Shared Access (ASA/LSA)
¹
, a new regulatory concept that allows license holders (incumbents) to share spectrum with other service providers, under well-defined conditions, unlocking additional bands which are used only partially in time and/or location. This paper shows the benefits of ASA, considering different methods to optimize the resources, by simulating an LTE network where a Mobile Network Operator (MNO) is allowed to use the 2300 MHz band as an ASA licensee.
