Abstract

Throughput on the GSM and LTE Femto coexistence network is highly dependent on the distribution conditions of the femtocells, including the number and position of the femtocells. In previous studies, there has been much discussion about network interference management for LTE femtocell integrated with GSM macrocells. However, previous studies have not clearly discussed the strategy for optimizing the throughput value in this coexistence network. LTE femtocell throughput performance is analyzed mathematically. The simulation results show that when femtocells are deployed near GSM BSs, namely at a distance of x = 0.1R, accommodating one and more LTE femtocells on each GSM macrocell causes a decrease in throughput of around 6.3 kbits/s and LTE femtocell throughput continues to decrease due to the increasing number of femtocells  deployed on GSM macrocell. Meanwhile, the throughput of LTE femtocell increases as the distance between the femtocell and the GSM BS increases. When changing from the distance x = 0.1R to x = R, the LTE femtocell throughput increases by about 1.3x102 kbits/s. So Optimization of LTE femtocell throughput can be done by reducing the number of femtocells deployed on GSM macrocells and adjusting LTE femtocell distribution patterns away from GSM BS.  Keywords— Throughput; LTE femtocell; GSM macrocell; coexistence

Abstract

This study is projected to be the initial design for the implementation of 5G technology, particularly in the Urban Macro (UMa) scenario, with a frequency of 3.5GHz and a bandwidth of 100 MHz. 3GPP (3rd Generation Partnership Project) TR 38.901 recommends performing performance analysis with line-of-sight (LOS) situations using the propagation model urban macro (uMa). In this study, 100 users are distributed at random distances to examine system capacity using the frequency reuse factors K = 1/3 and K = 1/7. According to the calculation results, this study demonstrates that system capacity is dependent on user distribution arrangement and the frequency reuse factor approach used. A high frequency reuse factor increases bandwidth efficiency and yields more optimum capacity. Furthermore, distributing users near the base station will boost capacity.

Abstract

Abstract – The development of cellular technology is accelerating, as is the exponential increase in data traffic, resulting in the creation of the following technology, namely 5G. This study looks at the throughput of the 5G network in various cluster sizes. In this study, integer frequency reuse (IFR) with a bandwidth of 100 MHz and a frequency of 3.5 GHz was used. The path loss Urban Macro (UMa) based on 3GPP 38.901 is employed in this study. The data was assessed and compared using computer simulations, and a comparison of throughput CDF values for each cluster size was obtained. When CDF = 0.9, the throughput of the N = 3 scenario is 6480 bps, which is greater than the huge throughput of the N = 4 scenario of 4860 bps and the large throughput of the N = 7 scenario of 2777 bps. According to the simulation, the cell with N = 3 cluster size has a greater throughput than the other scenarios. The cell with the smallest cluster size had the maximum throughput, whereas the largest had the lowest.

Abstract

The rapid growth in the use of data-driven mobile devices such as smartphones, tablets, and other connected terminals has significantly increased the demand for high-speed mobile data services. To address this challenge, 5G networks must adopt more efficient architectural strategies. This paper presents a design study of 5G cellular networks based on a layered cell structure, focusing on both theoretical analysis and computer-based simulations. A traditional single-layer cell is restructured into two-layer and three-layer configurations to evaluate the impact of layering on network performance. User devices are randomly distributed within the coverage area and connected to a central 5G base station. The simulation results, supported by theoretical modeling, demonstrate that layered cell architectures offer notable improvements in data capacity compared to the single-layer design. Among the scenarios tested, the three-layer structure achieves the highest performance, reaching up to 39,78 Mbps. These results provide valuable insights for the development and optimization of layered architectures in next-generation 5G cellular networks

Abstract

The coexisting of LTE femtocell with existing GSM network is proposed to address the challenge of limitation radio frequency spectrum.  SINR femtocells on coexisting networks are highly depend on conditions of distribution of femtocells, including the number and position of femtocells. On previous study have been extensively discussed coexistence of LTE femtocell integrated with GSM network. But it has not been discussed clearly how the strategy for increasing SINR femtocell in this coexisting network. In this study, various factors that affect SINR femtocell performance is analyzed mathematically. Simulation results show that SINR LTE femtocell increase about 0,2dB for every reduction of one femtocell deployed on the GSM network. When m = 2, SINR LTE femtocell reach 48.3dB then improve become 48.5dB when m=1. Meanwhile, when position of femtocell away from GSM base station from   x = 0.1R to x = R, SINR LTE femtocell increase about 2.5dB for a single femtocell on each GSM network. So as to increase SINR LTE femtocell can be done by reducing the number of femtocells deployed on GSM network and set LTE femtocell distribution patterns away from GSM base station.
