Abstract
Long-range, narrowband transmission using near vertical incidence skywave (NVIS) or other communications relying upon reflection off of the ionosphere to facilitate communications is contemplated, such as to enable low-power, low-rate wireless transmission of data from sensors, IoT devices or other componentry over large distances.
Claims20
A method for maximizing a communication range of a IoT device to facilitate long-range, narrowband wireless transmission of data, the method comprising:
- receiving data from the IoT device, the IoT device generating the data at a first frequency greater than a maximum frequency required for Near Vertical Incidence Skywave (NVIS) communications;
- converting the data to a second frequency sufficient for NVIS communications;
- and
- transmitting the data at the second frequency from an NVIS antenna associated with the IoT device.
The method of claim h further comprising retransmitting the data at a third frequency from the NVIS antenna when the IoT device fails to receive an acknowledgment for the data transmitted at the second frequency, the third frequency being different than the second frequency and sufficient for NVIS communications.
The method of claim h wherein:
- the first frequency is greater than 100 MHz;
- and
- the second frequency is no more than 100 MHz.
A system for long-range, narrowband wireless transmission of data, the system comprising:
- an IoT device for generating the data at a first frequency greater than a maximum frequency required for Near Vertical Incidence Skywave (NVIS) communications;
- a converter for converting the data to a second frequency sufficient for NVIS communications;
- and
- an antenna for transmitting the data off of the ionosphere at the second frequency.
