Abstract

It takes a long time to process inventory items are done manually using an inventory form before entered on thecomputer database. Using the android-based application on a smartphone as a replacement for an inventory form,then the inventory to be faster because reading or inputting data on a computer database can be done directlythrough the app android by utilizing the Wi-Fi network using client-server concept. Computer as a server thatprovide special services to the client (android application on the smartphone) that store and read the data if requiredby the client. The protocol used in data communication between a server computer with android application is TCPand HTTP protocol with a static IP address. Analysis of data packet transmission is done using Wireshark softwareand parameters measured were the flow of data packets and time delay. The test results on the time delay of the datadelivery show that greater the distance between the access point and client (android), the time delay of datatransmission will be greater with an average value of 14 ms. The time required to complete all inventory processusing android application on the smartphone at 7 minutes 45 seconds. whereas if inventory is done manually takestime for 21 minutes 64 seconds.Keyword : Data packets transmission, time delay, Wi-Fi, android, client-server

Abstract

Seiring dengan berkembangnya teknologi telekomunikasi yang pada saat ini banyak digunakan oleh masyarakat yaitu Long Term Evolution (LTE), dibutuhkan perencanaan jaringan agar teknologi tersebut dapat dinikmati secara optimal. Perencanaan jaringan LTE meliputi perencanaan secara cakupan, dan perencanaan secara kapasitas. Dalam hal ini perencanaan jaringan LTE menggunakan Base Trasnceiver Station (BTS) existing yang berarti memanfaatkan BTS yang sudah ada untuk dijadikan eNodeB, pada percobaan ini menggunakan data koordinat dari BTS operator x, pemanfaatan BTS existing dalam suatu perencanaan dapat menekan biaya dari segi infrastruktur dan penerapannya lebih mudah sehingga pengguna dapat dengan mudah mengakses teknologi ini dari perangkat. Pada perencanaan jaringan LTE menggunakan alat bantu sotfware Atoll, dari hasil uji coba simulasi menggunakan Atoll untuk perencanaan secara cakupan,yang didapatkan melalui prediksi daya pancar didapatkan nilai rata–rata -86,69dBm dan -89,21dBm yang termasuk kedalam kategori baik dan nilai kuat sinyal sebesar 14,6 dB dan 13,89 dB termasuk juga dalam kategori baik. Perencanaan secara kapasitas melalui simulasi user pada suatu daerah didapatkan user yang terkoneksi dengan eNode B adalah 98,2% dan 95% sisanya tidak melakukan aktivitas uplink maupun downlink. Hasil prediksi dari Atoll dapat dipengaruhi oleh pengaturan di dalam Atoll yang sangat peka terhadap kesalahan seperti dalam memasukkan angka yang berhubungan dengan perencanaan.

Abstract

The improvement of Long Term Evolution (LTE) radio access network services is affecting the increased value of traffic load in its network, which is causing traffic unbalance between cells in LTE Radio Access Network (RAN). Users will be served with ineffective resource block allocation which will make the total of gained throughput are not optimal. A method is required to move network load from overloaded cells to underloaded cells in order to balance the resource block allocation optimally. By using NS-3.26 simulation, User Throughput Based (UTB) predictive Mobility Load Balancing (MLB) method is tested with RandomWalkMobilityModel for each user. This method produces an improvement of 2,29 % in average of total throughput of 63,33 % successful optimization.

Abstract

Increasing user requirements for LTE networks, data traffic from eNodeB to core network is also increases, therefore, the recommended solution for meeting this high data traffic is to use a backhaul network design. Backhaul is the path or network used to connect eNodeB with the core network. In this research, backhaul technology used is wi-fi 802.11ac backhaul and microwave backhaul. In this study begins by collecting existing data, then perform capacity calculations to find out the number of eNodeB needed and to find out the capacity of the backhaul links to be designed, then determine the antenna height to achieve LOS conditions, then calculate the desired performance standards and calculate the backhaul network link budget on microwave and wi-fi technologies. Based on the calculation results in terms of capacity, the total user target is 90,167 users and has a throughput capacity per eNodeB of 61 Mbps. In the link-capacity calculation, the total link capacity is 427 Mbps. From the simulation results that using microwave technology, the average RSL value is -30.90 dBm, the value meets the -57 dBm threshold standard and the value of availability does not meet the standard of 99.999% because the average value obtained is 99.998095%. Whereas for wi-fi technology, the average RSL value is -39.24 dBm and meet the -72 dBm threshold standard, for the average availability value meets 99.999% standard, with a value of 100%. From the results of the two technologies, can be conclude that the wi-fi technology is more suitable for the use of backhaul network design in Ciputat Sub-district.

Abstract

Abstract — The fifth-generation cellular technology (5G) is predicted to adopt a high-frequency channel, which could lead to a new challenge, namely, wave propagation attenuation. This attenuation is affected by natural conditions, such as barometric pressure, rain rate, humidity, and vegetation density. This paper proposes a 5G channel model under the barometric pressure effect to address the issue. The channel model is obtained from series computer simulations by operating frequency of 28 GHz and real-field parameters of Yogyakarta environments. The 5G channel model frameworks consist of two steps. First, generate the instantaneous Power Delay Profile (PDP) using NYU Wireless Simulator with real-field parameters of the environment. Second, the instantaneous PDP is then used to calculate the representative PDP. PDP differs from one country to another, especially on 5G technology, because of the high-frequency band, which is sensitive to nature. To observe the barometric pressure effect, we need to generate the instantaneous PDP with minimum and maximum barometric effects. PDP value used to calculate the outage probability of channel capacity (C) is smaller than the coding rate (R), indicating a failure of detection at the receiver based on the Shannon theory. Outage probability is obtained by the cumulative distribution function of the capacity evaluated against the coding rate. Outage probability results in both scenarios can reach a point of 10-4, for coding rate ½ needs 17.649883 dB, coding rate ¾ needs 20.020953 dB, and coding rate 1 needs 22 dB. This shows that barometric does not significantly influence the performance of the 5G communication system.

Abstract

This research uses repetition codes based on Coded Random Access (CRA) to support Internet of Things (IoT) to give priority to emergency commutations in super-dense networks. Degree distribution for emergency group and general group are obtained with extrinsic information transfer (EXIT) analysis to achieve small error performance shown by the very small gap between emergency group curve and general group curve. This research also evaluates performance by observing throughput and packet-loss rate (PLR) parameters from every groups. Offered traffic in PLR  for emergency group user is G= 0,7 packet/slot without fading and G= 0,65 packet/slot with fading, while for public group is G=0,699 packet/slot without fading and G=0,42 packet/slot with fading. Peak throughput for emergency group is G= 0,737 packet/slot without fading and G= 0,729 packet/slot with fading. Peak Throughput for public group is G= 0,699 packet/slot without fading and G=0,685 packet/slot with fading. Throughput values of emergency group are higher than those of the general group, indicating successful process of giving priority for emergency group.
