Free Space Optics Technology (FSO)
The transmission of modulated visible or infrared (IR) beams across the atmosphere to produce Broadband communications is known as free-space optics (FSO), sometimes known as free-space photonics (FSP). Laser beams are most employed, however non-lasing sources such as light-emitting diodes (LEDs) or infrared-emitting diodes (IREDs) can also be used. FSO theory is substantially the same as fiber optic transmission theory. The distinction is that instead of being steered by an optical fiber, the energy beam is collimated and delivered through clear air or space from the source to the destination.

Orthogonal Frequency - Division Multiplexing (OFDM)
OFDM stands for Orthogonal Frequency Division Multiplexing, which separates a high data rate modulating stream into numerous slowly modulated narrowband close-spaced subcarriers, making it less susceptible to frequency selective fading. OFDM is a frequency-division multiplexing (FDM) method developed by Bell Labs’ Robert W. Chang in 1966. To convey data in parallel, OFDM uses several closely spaced orthogonal subcarrier signals with overlapping spectra. Fast Fourier transform algorithms are used in demodulation.Click here to continue reading

Electrodynamic Tether
Electrodynamic tethers are long, thin conductive cables
stationed in space that can be used to induce power by removing kinetic energy
from their orbital stir, or to produce thrust when adding energy from an on-
board source. In either case, the frictional or thrust force, is produced
electrodynamically, through the commerce between moving charges and glamorous
fields. From then, we notice that the operation of electrodynamic tethers is
confined to elysian objects that have anon-zero glamorous field and ionospheric
tube (e.g., Earth, Jupiter, Saturn, etc, not the moon or Mercury, etc).Click here to continue reading

Sigfox
Ludovic Le Moan and Christophe Fourtet founded Sigfox in 2010 with the goal of connecting every object in our physical world to the digital realm. The two French founders created a global Internet of Things network based on low power, long range, and little data that provides end-to-end communication.. Sigfox has been powering a sustainable and connected world since its beginnings, paving the way for the next Internet revolution.Click here to continue reading https://blog.kct.ac.in/sigfox/
