A comparison study of passive Optical Networks (PONs) and Active Optical Networks (AONs) had been presented. Powerful software design tool "OptiSystem" was used to perform this study. This comparison was based in terms of power consumption, communication distance, Q-factor, and bit error rate (BER) for each network system.

Abstract. The antenna application for internet of things (IoT) in urban infrastructure is introduced. Here, an effective design of microstrip 3D antenna for a RFID system in IOT which can also be used in narrow-band wireless communication is proposed. The antenna is combination of meander line techniques implemented with 3D structure resulted to miniature size of antenna that will be useful in many application. The critical parameters analysis and simulation results demonstrate the validity of the antenna with high gain and impedance matching are discussed as well.
