Stability tests in time of OAM multiplexing schemes in highly disturbed environments
Abstract
We report the results of tests of data transmission and signal stability in time of two different wide-band multiplexing (MUX) schemes, each in a point-to-point configuration, based on electromagnetic waves carrying Orbital Angular Momentum (OAM) in noisy real-world settings. Each radio link transmitted two high definition wide--band analog TV channels in the same frequency band with FM-carrier centered at GHz and MHz bandwidth, encoded with different OAM modes in the same polarization state, uninterruptedly for months during the world exhibition ``Globale--Digitale'' at ZKM in Karlsruhe and in other months time slots taken in the following years, hours per day. We show the practical feasibility of the use of stable OAM radio/TV links in the real world for a long time, paving the way for for secure and efficient communication schemes also under electromagnetic jamming conditions.
