Time, polarization, and wavelength multiplexing schemes have been used to\nsatisfy the growing need of transmission capacity. Using space as a new\ndimension for communication systems has been recently suggested as a versatile\ntechnique to address future bandwidth issues. We review the potentials of\nharnessing the space as an additional degree of freedom for communication\napplications including free space optics, optical fiber installation,\nunderwater wireless optical links, on-chip interconnects, data center indoor\nconnections, radio frequency and acoustic communications. We focus on the\norbital angular momentum (OAM) modes and equally identify the challenges\nrelated to each of the applications of spatial modes and the particular OAM\nmodes in communication. We further discuss the perspectives of this emerging\ntechnology. Finally, we provide the open research directions and we discuss the\npractical deployment of OAM communication links for different applications.\n
