1. A method for extending network connectivity from a core network to one or more remote mobile networks using wireless broadband, the method comprising:
installing a first security gateway between the core network and a plurality of broadband base stations located at a periphery of the core network, the broadband base stations for wirelessly communicating with a corresponding remote transceiver in each remote mobile network;
creating a virtual layer 2 (data link) overlay network interconnecting the broadband base stations;
activating a local layer 3 network protocol between the first security gateway and the core network, wherein the local layer 3 network protocol is compliant with the Open Systems Interconnection (OSI) model;
activating a sensor protocol between the first security gateway and each remote mobile network, the sensor protocol being configured to, for each remote mobile network and corresponding remote transceiver,
use wireless broadband communication through the broadband base stations to the remote transceiver when at least one of the broadband base stations is in range of the remote transceiver, and
use satellite communication between the core network and the remote mobile network when none of the broadband base stations are in range of the remote transceiver, wherein for each remote mobile network, the satellite communication is between an internal very-small-aperture terminal (VSAT) gateway at the periphery of the core network and a geosynchronous or geostationary satellite, and between the satellite and a remote VSAT gateway in the remote mobile network;
providing each remote mobile network with a remote layer 3 network protocol that uses the wireless broadband communication until disconnected from all of the broadband base stations, and then uses the satellite communication while none of the broadband base stations are connected to the corresponding remote transceiver of the remote mobile network, wherein the remote layer 3 network protocol is compliant with the Open Systems Interconnection (OSI) model; and
installing a satellite security gateway between the core network and the internal VSAT gateway.
