Abstract

A private wireless network for providing connections between a public wireless network and wireless devices includes a first interface to the public wireless network and at least one second interface to the wireless devices. A wireless communications network interconnecting the first interface and the second interface implementing a MulteFire wireless communications standard includes a first plurality of control layers. The wireless communications network further comprises a plurality of nodes within a mesh network. A plurality of transceivers is associated with each of the plurality of nodes within the mesh network. Each of the transceivers implement a software defined radio that may be configured within a plurality of transceiving configurations. At least one server implements at least a portion of the wireless communications network within the at least one server. The at least one server is configured to select a first slice portion of the first plurality of control layers of the wireless communications network and a first slice portion of at least a portion of the plurality transceivers in a first transceiving configuration to support operation of a first application or service and to select a second slice portion of the first plurality of control layers of the wireless communications network and a second slice portion of at least the portion of the plurality transceivers in a second transceiving configuration to support operation of a second application or service.
