Abstract

To enhance the experience of mobile phones, new data services has been emerged. With increasing demand of\nnetwork infrastructure, it is difficult to handle the data services. The technology used to solve the issue is OWC. In this paper,\nvarious technologies like FSO, VLC, Inter-Satellite OWC has been discussed. Various modulation methods like CSRZ,\nMDRZ and DRZ of Inter-Satellite OWC has been compared at bit rates of 40 and 50 Gbps. The comparative results show\nthat on increasing bit rate, quality factor degrades and BER increases. The challenges and various applications have also been\nexplained.
