to the user's mobility pattern, so that a virtual antenna group moves together with the mobile user. A mathematical model is developed and performance evaluation is also conducted and presented, demonstrating zero packet loss and call dropping probability values in high-rate wireless services for a broad range of mobile speeds up to 40m/sec and(More)
—We demonstrate a Moving Extended Cell concept that provides seamless communication with high end-user mobility in broadband 60 GHz Radio-over-Fiber networks. Mathematical and simulation-based performance analysis are presented, showing that this technique can guarantee seamless connectivity irrespective of the overlapping area between adjacent cells(More)
—Digital optical logic circuits capable of performing bit-wise signal processing are critical building blocks for the realization of future high-speed packet-switched networks. In this paper, we present recent advances in all-optical processing circuits and examine the potential of their integration into a system environment. On this concept, we demonstrate(More)
Free space optical (FSO) communications links is a promising solution for the provision of high data rate point to point communications. The FSO links due to their huge bandwidth and license free spectrum provide a viable communication solution between Unmanned Aerial Vehicles (UAVs) and fixed Ground Stations (GS). It is of great importance to characterize(More)
With metal stripes being intrinsic components of plasmonic waveguides, plasmonics provides a "naturally" energy-efficient platform for merging broadband optical links with intelligent electronic processing, instigating a great promise for low-power and small-footprint active functional circuitry. The first active Dielectric-Loaded Surface Plasmon Polariton(More)
We present recent advances in multi-wavelength, power-equalized laser sources that incorporate a semiconductor optical amplifier (SOA) and simple optical filters, such as Lyot-type and Fabry-Perot, for comb generation. Both linear and ring-cavity configurations are presented, and single-pass optical feedback technique is proposed to improve the performance(More)
We present a novel client-weighted mediumtransparent medium access control (CW-MT-MAC) protocol with enhanced fairness service delivery properties accompanied by a low-loss remote access unit (RAU) architecture for use in indoor, Gbps-capable, 60 GHz radio-over-fiber (RoF) wireless local area networks (WLANs). Our approach relies on incorporating a(More)
The 60 GHz millimeter-wave band remains the only unlicensed, high-capacity spectral zone which is however limited to Personal Area Networks due to its picocellular nature. Facilitating mm-wave communication onto Radio-over-Fiber infrastructures alleviates the picocellular range handicap while it offers multi-Gbps wireless connectivity. In light of the above(More)
