The scarcity of RF spectrum at lower frequencies has recently been addressed by millimeter wave transmission in wireless and radio-over-free-space optics networks for more flexible frequency spectrum allocation. In this paper, we report successful transmission of 2×4×20Gbit/s-40GHz information over an orthogonal frequency division multiplexing (OFDM) based Radio-over-Free space optics (RoFSO) transmission link by incorporating hybrid spectrum-slicing based wavelength division multiplexing (SS-WDM) and mode division multiplexing (MDM) of Hermite Gaussian (HG) modes up to a link reach up to 30 km under clear weather conditions. The proposed link is also investigated under the effect of atmospheric turbulence..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
