Abstract

Optical Wireless Communications (OWCs) can play vital role in providing communication in healthcare infrastructure’s, where contagious patients are admitted or treated as well as other patients are coming without any side effects as of radio frequency communication. In this paper, we propose high-speed cost-efficient free space optical (FSO) system for transmission of information (20 Gbps) inside healthcare premises comprising of number of buildings by integrating mode division multiplexing (MDM) scheme. The MDM scheme uses Laguerre Gaussian (LG) 00 and 01 modes whereas a simple On off Key (OOK) encoding scheme is employed for the proposed MDM-FSO system. The reported results show the efficient transmission of 20 Gbps data over 27 km of FSO link under clear atmospheric condition. Moreover, the proposed MDM-FSO link is evaluated under the impact of different fog conditions—low, medium and heavy.
