Patent ID: 7778230

Claim:
A stack of wireless network routers comprising: a master router comprising a first CPU for performing program steps, a first memory module in communication with the first CPU, a first and a second wire network interface device each in communication with the first CPU and each configured as a host network access point (AP) for communicating with locally reachable client devices using a wire local area network (LAN) communication protocol, and a wireless network interface device in communication with the first CPU and configured as a host network access point (AP) for communicating with locally reachable client devices using a wireless local area network (LAN), a cellular network interface device in communication with the first CPU wherein the cellular network interface device in communication with the first CPU is configured to connect to a host cellular network reachable thereby using a radio frequency band and cellular network communication protocol matched to the host cellular network and to become a client of the host cellular network and exchange network communication signals between the first CPU and the host cellular network; one or more slave routers each comprising a second CPU for performing program steps, a second memory module in communication with the second CPU, a first and a second wire network interface device each in communication with the second CPU and each configured as a host network access point (AP) for communicating with locally reachable client devices using a wire local area network (LAN) communication protocol, and a cellular network interface device in communication with the second CPU wherein the cellular network interface device in communication with the second CPU is configured to connect to the host cellular network reachable thereby using a radio frequency band and cellular network communication protocol matched to the host cellular network and to become a client of the host cellular network and exchange network communication signals between the second CPU and the host cellular network; a first wire jumper connected between the first wire network interface device of the master router and the second wire network interface device of one of the one or more slave routers for exchanging network communication signals between the second CPU and the first CPU over a wire LAN using a wire LAN communication protocol; and, one or more second wire jumpers connected between the first wire network interface device of each of the one or more slave routers and the second wire network interface device of another of the one or more slave routers for exchanging network communication signals between interconnected second CPU is over a wire LAN using a wire LAN communication protocol.
