Abstract: Systems and methods are disclosed for extending the communication range of mobile communication devices. A long-range radio device is controlled by a control application on a host smartphone. The long-range radio device provides signal paths for two different radios, one employing a long-range (LoRa) modulation format, and another employing a high data-rate encoding such as FSK. The system provides graceful degradation in data rate as radio link distance increases and received signal strength decreases. In addition to switching between radios, variable compression and buffering are used to adapt usage to supportable data rates. Voice, other audio, video, text, binary, and other data formats are supported, as also a wide range of co-resident host apps. Unidirectional and bidirectional links can be used.

Abstract: A system and a method are disclosed for enabling communication between mobile communication devices. A mobile communication device receives a message sent by a sender, the message including a recipient, a message identification, and a payload. The mobile communication device determines whether it is the intended recipient of the message. If the mobile device that received the message is the intended recipient, the mobile device sends an acknowledgement response message to the sender of the message. Otherwise, if the mobile device that received the message is not the intended recipient, the mobile device forwards the message to a second mobile device.
