In this paper we present the design concept and experimental evaluation results of a newly developed DWDM Radio on Free Space Optics (RoFSO) system capable of transmitting simultaneously multiple RF service signals. The system performance is evaluated under effects of atmospheric turbulence over 1-km free-space transmission. Effectiveness of a proposed tracking scheme used to mitigate beam angle-of-arrival...
In the near future, wireless local area networks (WLANs) will overlap to provide continuous coverage over a wide area. In such ubiquitous WLANs, a mobile node (MN) freely moves between WLANs with different IP subnets during VoIP communication. However, existing methods cannot sufficiently maintain VoIP quality during handover due to changes of IP address and inappropriate execution of handover. To...
