Abstrak -Penelitian ini menjelaskan tentang sistem komunikasi radio base station femtocell yang diletakkan pada tiang lampu jalan. Frekuensi yang digunakan 47 GHz. Analisis pada penelitian ini terdiri dari variasi daya transmitter, dan variasi code rate dari signal-to-interference-plus-noise-ratio threshold 16 QAM. Daya transmitter yang digunakan 10 mW hingga 200 mW. Variasi code rate dari signal-to-interference-plus-noiseratio threshold 16 QAM terdiri dari 1/2, 2/3, 3/4, dan 4/5. Sebagai hasil ditunjukkan hubungan antara daya transmitter dan code rate, dan hubungan antara persentase daerah tercakup pada lintasan mobile station dan code rate. Berdasarkan hubungan antara persentase daerah tercakup and code rate didapatkan semakin meningkat nilai code rate maka nilai persentase pada daerah tercakup semakin berkurang.Kata kunci -47 GHz, 16 QAM, femtocell, tiang lampu jalan Abstract -This research describes about the communication systems at radio base station femtocell that placed at street lamp.

In this paper, we present an efficient handoff decision strategy and a mobility state detection (MSD) scheme for heterogeneous networks (HetNets). Due to base station (BS) densification, HetNets occasionally face unnecessary handovers and service failures. Since velocity plays a crucial role in handover process, its knowledge is imperative for effective mobility management. Furthermore, due to limited power in mobile devices, emphasis is in investigation of velocity estimators that are at service provider end. Thus, we propose two maximum likelihood-based velocity estimators exploiting handover count and sojourn time measurements, respectively. Our analysis illustrates that both the estimators are asymptotically unbiased and efficient. In addition, we also notice that variance of sojourn time-based estimator is smaller than that of handover count-based estimator. Considering superiority of sojourn time-based estimator, we propose a handover decision strategy to minimize unnecessary handovers. Here, we first predict the sojourn time of upcoming BSs on the basis of velocity estimated via sojourn time samples. Next, BSs whose predicted sojourn time are greater than a prespecified threshold are then considered to identify the next serving BS. Finally, we select next serving BS on the basis of minimum cost for satisfying quality-of-service parameters such as bandwidth, security, monetary cost, and available power at user device. This work also exploits estimated velocity to investigate MSD specified in LTE standards. The numerical and simulation results validate our approach by illustrating accuracy in velocity estimation, reduction in frequent handovers and service failures, and improvement in MSD.
