Towards last-mile connectivity in 6G-IoT: An integrated MIMO-FSO communication system and FBG sensors under atmospheric attenuations, strain and temperature effects by R. Arunachalam, Rupali Singh, M. Vinoth Kumar

“…In light of developing a 6G IoT network in an open environment, this paper analyses the impact of temperature and strain on FSO communication links using Fiber Bragg Grating (FBG) sensors. FSO systems are sensitive to temperature variations, and the position of the receiving telescope can be altered by mechanical strain that can affect the refractive index of the atmosphere, leading to signal attenuation and pointing errors. …”
