1. A gateway device for use with a wide area network (WAN), a wireless WAN, a local area network (LAN) created by the gateway device, a client device and a hotspot client device, the gateway device comprising:
a memory, the memory storing instructions thereon;
a primary communication system comprising a first radio and an interface, the primary communication system being configured to enable the gateway device to operate in a primary mode of operation;
a secondary communication system comprising the first radio, a second radio and the interface, the secondary communication system being configured to enable the gateway device to operate in a hotspot mode of operation, wherein during the primary mode of operation the first radio is active and the second radio is inactive, and wherein during the hotspot mode of operation the first radio is inactive and the second radio is active; and
a processor configured to execute the instructions to cause the gateway device to:
instruct the primary communication system of the gateway device to:
communicate, via the LAN, with the client device so as to transpond a first client device data between the client device and the WAN, wherein the gateway device connects to the WAN via a communication channel; and
wirelessly communicate with the hotspot client device so as to transpond a second client device data between the hotspot client device and the WAN;
detect a loss of connection with the WAN via the communication channel;
send an instruction to the hotspot client device to begin operating as a Wi-Fi hotspot for the gateway device; and
instruct the secondary communication system of the gateway device to transpond, over a dedicated channel, a third client device data between the client device and the WAN via the Wi-Fi hotspot,
wherein the dedicated channel comprises a communication from the second radio of the gateway device to a secondary radio of the hotspot client device, and a communication from the hotspot client device to a cellular network.
