OfficeSpace is a company that provides office space for rent. OfficeSpace owns the building, and rents out fully furnished and equipped office space to SMEs. Next to providing toilets, reception services, coffee and lunch facilities, office rental companies also have to ensure that their customers can use IT facilities and have excellent (mobile) Internet access.
OfficeSpace has decided to fully rely on mobile communication for the internal Internet access and IT services (printers, beamers, et cetera). All devices are connected via PLMN communication. All servers et cetera are in the cloud. This saves greatly on the amount of cabling needed in the office. Furthermore, it provides the flexibility needed with the ever changing tenants.
OfficeSpace's customers may use any of the mobile networks. And with the addition of visitors it is clear that OfficeSpace needs to ensure there is coverage for all mobile users, regardless of subscription. Because of the high frequencies needed to provide sufficient capacity for an in office mobile network, indoor small cell base stations are used to cover the office floors and various meeting rooms. Because installing a separate indoor infrastructure for each of the mobile operators would be too costly, OfficeSpace together with the mobile operators has implemented a shared radio access network. Implementing a shared radio access network implies that there is only one set of indoor base stations (plus the required connectivity of these base stations) for all operators.
