Je hebt een klacht over de onderstaande posting:
In 5G noemen ze dit beamforming. http://spcomnav.uab.es/docs/conferences/Arash_GLOBECOM_2015.pdf "Among these challenges, the severe path loss at those high carrier frequencies stands out. The resulting loss in signal-to-noise ratio (SNR) must be countered through sophisticated beamforming at the transmitter and/or receiver side, leading to highly directional links [3]–[5]" "Beam tracking helps to keep track of the receiver devices during mobility" https://core.ac.uk/download/pdf/287373353.pdf in 5G editie dus wellicht makkelijker, geen BS tower triangulation meer nodig dan door al de complexe algoritmes.
