Method and related systems for communication via ELF and ULF waves
[Category : - Telecommunications]
[Viewed 639 times]
Link
The present disclosure provides a method for long-range communication through underwater and underground environments by converting encoded message data into spherical coordinates and rotating a magnet about axes of rotation corresponding to those spherical coordinates at a transmitter. A receiver configured to detect the magnetic dipole field of the generated electromagnetic wave can thus determine the orientation of the magnetic dipole, deduce the spherical coordinates, and decipher the encoded data. A system comprising a mechanical antenna transmitter and receiver with a magnetic field sensor arrangement for carrying out the method is also provided.
Financial information
Problem:
In harsh environments, the majority of electromagnetic waves can't achieve wireless communication over medium to long range. Only extremely/super and ultra-low frequency waves (ELF, SLF and ULF) can achieve this communication over medium to long depths. The traditional generation of these waves requires a very large size antenna with huge electrical power consumption. These drawbacks narrow the applications of this technology down to military and other specific applications.
Our solution:
We develop a compact and low power consumption mechanical magnetic communication system for generating and receiving extremely/super and ultra-low frequency waves. Our system can achieve a data transmission rate sufficient to send real-time text messages, instructions and sensor data. Our novel configuration enables a transmission rate from five to ten times higher than the available magnetic mechanical antennas.
Innovation:
Our solution relates to a novel mechanical antenna configuration and method of using it whereby a spherical permanent magnet surrounded by actuator coils is induced to rotate about different axes of rotation with the azimuth and inclination angles of the axes corresponding to characters of a hexadecimal data packet. A receiver array configured to deduce the axes of rotation can then decode the message, enabling faster transmission of data in ELF, and SLF waves. Our technology is protected by a granted United states patent (US 11,483,078 B1) on Oct. 25, 2022, the patent application was filed on May 31, 2022.
