1. A wireless dual-function network device for use in a wireless communication network, said wireless dual-function network device comprising: a housing containing said at least one printed circuit board (PCB), a power management module, a RF transceiver, a microprocessor with program memory and flash memory;wherein said power management module provides electrical power to said PCB, said RF transceiver, and said microprocessor with program memory and said flash memory;wherein said flash memory stores dual-function firmware which, when executed by said microprocessor and said program memory, configures said microprocessor to operate in a first mode as a wireless network router, or in a second mode as a wireless network coordinator;wherein said RF transceiver is coupled to said microprocessor and generates data signal packets in both said first mode and said second mode;wherein an RF antenna structure is coupled to said RF transceiver in order to send and receive the data signal packets in both said first mode and said second mode;wherein an initial configuration of said microprocessor is to operate in said first mode as a wireless network router, and another wireless dual-function network device is configured to operate in said second mode as a first wireless network coordinator; andwherein if said another wireless dual-function network device is permanently or temporally disabled on said wireless communication network, then said microprocessor reconfigures the dual-function firmware to operate in said second mode as a replacement wireless network coordinator on said wireless communication network. 2. The wireless dual-function network device of claim 1, wherein said wireless communication network is a personal area network (PAN). 3. The wireless dual-function network device of claim 1, wherein said PCB comprises a multi-layer printed circuit board (PCB); said PCB has one or more LED indicators for visually indicating the status of operation of said wireless dual-function network device. 4. The wireless dual-function network device of claim 1, which further comprises a GPS module operably connected to said microprocessor, for locating said wireless dual-function network device using a real-time location technique. 5. The wireless dual-function network device of claim 1, wherein said housing is provided with an external wall source power adapter. 6. The wireless dual-function network device of claim 5, wherein said external wall source power adapter comprises an electrical wall plug having electrical prongs for plugging into an electrical wall socket. 7. The wireless dual-function network device of claim 1, wherein said RF antenna structure is a phased-array antenna structure. 8. The wireless dual-function network device of claim 1, which further comprises a backup battery source for maintaining electrical power to said wireless dual-function network device in the event of a short-term power failure.
