1. A method of controlling packet flow, the method comprising:
aggregating, by a hotspot access point, a connection of at least one unlicensed frequency band and a connection of at least one licensed frequency band to form a hotspot backend connection for the hotspot access point providing an aggregated bandwidth spectrum;
allocating, by the hotspot access point, the aggregated bandwidth spectrum to at least one device connected with the hotspot access point through a tethered connection;
receiving, by the hotspot access point, one or more packets from the at least one device in an uplink direction towards one or more host servers via an interface;
determining, by the hotspot access point, at least one communication parameter of the one or more packets;
encapsulating, by the hotspot access point, the one or more packets with at least one encapsulating parameter to form one or more encapsulated packets;
encrypting, by the hotspot access point, at least one of a payload, a control information, and a header in the one or more encapsulated packets to form one or more encrypted packets;
transmitting, by the hotspot access point, the one or more encrypted packets to a plurality of output interfaces based on the at least one communication parameter through a plurality of sub-flows of a transport layer aggregator within a transport layer of the hotspot access point, the plurality of sub-flows comprise at least one sub-flow over the at least one unlicensed frequency band and at least one sub-flow over the at least one licensed frequency band;
detecting, by the hotspot access point, an error in one or more sub-flows from the plurality of sub-flows;
terminating, by the hotspot access point, the one or more sub-flows; and
retransmitting, by the hotspot access point, the one or more packets through remaining sub-flows.
