Abstract: Laminated composite wall panels, compositions used to make wall panels, and methods for manufacturing wall panels. Laminated composite wall panels include a core composite panel structure and a fiber-based sheet (e.g., paper or fabric) layer covering at least one side of the core composite panel structure. The core composite panel structure includes a foam core sandwiched between thin protective layers (e.g., fiber mesh reinforced cementitious layer, thermoset polymer layer, and/or magnesium oxide layer). An optional intermediate polymer layer can be formed from a light-cured, UV-cured, and/or chemical-cured resin. The laminated composite wall panels can be used to replace gypsum drywall panels and are advantageously lighter weight, have beveled edges, and can have a smooth or textured finish. The laminated composite wall panels can be cut, drilled, and screwed onto structural elements of buildings, such as wall frames comprising wooden or metal studs or ceiling joists.

Abstract: A method of coordinating a plurality of radio access networks (RANs) includes aggregating, with a gateway, communications interfaces between a plurality of RANs and a packet core network through the gateway. A plurality of radio nodes (RNs) in each of the RANs is communicatively coupled to the gateway and to user equipment (UE) devices associated with the RNs in each of the RANs. The gateway also controls and coordinates mobility of the UE devices within and among the RANs. In addition, the gateway acts as a virtual enhanced NodeB (eNB) to the packet core network, thereby hiding the aggregated communications interfaces from the packet core network.
