The main focus of this paper is to optimize the coverage of each 4G LTE network cell within the service area. There are many algorithms can be implemented to determine the optimal 4G LTE coverage area including the deterministic and heuristic approaches. The deterministic approach could solve accurately the optimization problem but need more resources and time consuming to determine the convergence parameters. Therefore, the heuristic approaches were introduced to improve the deterministic approach drawback. The methods used are the Differential Evolution Algorithm (DEA) and Adaptive Mutation Genetic Algorithm (AMGA), which are categorized as metaheuristic approach. The DEA and AMGA algorithms have been widely used to solve combinatorial problems, including for solving the network optimizations. In the network optimization, coverage is strongly related to 2 objectives, which are reducing the black spot area and decreasing the overlapping coverage areas. Coverage overlap is a condition when some cell sites in an area overlap. It implies in the occurrence of hand off and an inefficient network management. This research aims to obtain an optimal 4G LTE network coverage and reduce the overlapping coverage areas based on effective e-Node B arrangements by using the DEA and AMGA algorithms. The simulations results showed that the DEA algorithm’s coverage effectiveness was 23,4%, and the AMGA Algorithm’s was 16,32%.

As the number of LTE 4G network subscribers increases, telecom operators must expand their coverage area to be able to serve the telecommunications needs of customers. Research on 4G LTE is still interesting to be studied because 4G LTE network is still developed.This study discusses the effect of the addition of e Node B to the coverage area of 4G LTE network. The research method used is survey, simulation. This research is done by taking data of telecommunication operator in north Balikpapan. From the research results for the 4G LTE network need to add 4 e Node B from 14 to 18 e Node B. By addition of e Node B number increased coverage area of 4G LTE network from 89.108 km2 to 132 km2

To assess the inverse kinematics (IK) of multiple degree-of-freedom (DOF) serial manipulators, this article proposes a method for solving the IK of manipulators using an improved self-adaptive mutation differential evolution (DE) algorithm. First, based on the self-adaptive DE algorithm, a new adaptive mutation operator and adaptive scaling factor are proposed to change the control parameters and differential strategy of the DE algorithm. Then, an error-related weight coefficient of the objective function is proposed to balance the weight of the position error and orientation error in the objective function. Finally, the proposed method is verified by the benchmark function, the 6-DOF and 7-DOF serial manipulator model. Experimental results show that the improvement of the algorithm and improved objective function can significantly improve the accuracy of the IK. For the specified points and random points in the feasible region, the proportion of accuracy meeting the specified requirements is increased by 22.5% and 28.7%, respectively.

In this article, the coverage area prediction of piezoelectric sensor network for detecting a specific type of under-surface crack in plate-like structures is addressed. In particular, this article proposes a simplified framework to estimate the coverage of any given sensor network arrangement when a critical defect is known. Based on numerical results from finite element methods (FEM), a simplified framework to estimate coverage area of any given network arrangement is developed. Using such a simplified framework, one can avoid time-consuming procedure of evaluating numerous FEM models in estimating sensor network coverage. Back-scatter fields of partial cracks are estimated using a proposed function, whose parameters are estimated from the results of a limited number of FEM simulations. The proposed function efficiently predicts the back-scattered field of any combination of transmitters and receivers for a given crack geometry. Superposition is used to estimate the coverage area of an arbitrary piezoelectric (e.g., PZT) sensor network. It is shown that the coverage area of a sensor network depends on both sensor network geometry and defect properties (e.g., crack inclination) and it is not necessarily a linear function of the number of sensors. Furthermore, it is shown that the network arrangement has an important effect on the geometry of the coverage area. Experimental results of a network of 14 PZTs in two clusters confirm the accuracy of the method.

Kata kunci: LTE, optimasi, physical tuning, Automatic Cell Planning, Atoll ABSTRACT The quality of the 4G (LTE) network is still unstable, causing bad coverage. To improve the quality of 4G network (LTE) can be done by sectoral antenna tuning optimization. Physical tuning of sectoral antennas includes changes in antenna height, azimuth and tilting antenna. In this study a sectoral antenna tuning physical optimization was carried out using the Automatic Cell Planning (ACP) method to meet coverage needs in West Purwokerto and North Purwokerto areas. The percentage of existing coverage sites has not met the KPI Operator standard for RSRP of 78.491% 100 (100) dBm and CINR of 65.669% ≥ (0) dB. The results of sectoral antenna tuning optimization using the ACP method have met the KPI Operator standard for RSRP of 90.037% ≥ (100) dBm and CINR of 94.868% ≥ (0) dB.
