Versatile wireless network system

The Service Transmit Equipment (STE) in the invention has one wireless networking interface communicating to a plurality of Client Utility Equipments (CUE) forming a cell network. The STE is the node router of the cell network. The cell network connects to other networks via the STE. A plurality of cell networks connect together to a core network forms a service wireless network system. The CUE is the edge network traffic control equipment; each connects to a plurality of clients with different service agreement predefined. The CUE controls the transition of the network packets from or to its clients. Only useful network packets from clients can be allowed into the service network. The system maintains a high efficiency of internal bandwidth utilization, and can service clients with a versatile networking performance.
