Point Placement

Information technology in the field of transmission that is currently developing, one of which is Wi-Fi. Wi-Fi devices provide user convenience in carrying out their activities. The quality of Wi-Fi network performance can be known by the reception of the signal received by the user. If the placement of an access point (AP) is done correctly, the network will be optimized. There are several propagation models in the room that can be used as a guideline in determining the placement of the AP, one slope model is a way to measure the average level of a building and only depends on the distance of the transmitter and receiver. This research was conducted in order to overcome the problem of Wi-Fi network area coverage at the Office of Communication and Information of the City of Palembang. This study conducted an experiment to change the layout of AP's placement, measure and calculate data in priority with the one slope model. The results of measurements and calculations carried out analysis and comparison in order to determine the results of the experiments conducted. The results of this study indicate that an attempt to change the AP layout with one slope model can overcome existing problems and get better Wi-Fi coverage area performance. In the calculation with the one slope model of the 2-trial access point placement results in a decrease and an increase in signal. The signal reduction occurred in experiment 1, whereas in experiment 2 (design 2) the signal increased by 1.46dBm.

Calculation Results

The main changes in the telecommunication during these present days come mainly from wired technology to wireless technology. The Wireless LAN (WLAN) configuration consists of an access point, connected to users using air medium. The postgraduate building of Universitas Udayana has been equipped with a wireless network, supporting the study activities within the building. This research explains regarding the signal level quality and the Quality of Service (QoS) by analyzing the Wi-Fi coverage. The measurements were divided into two models, with and without barriers. The highest result comes to -42 dBm, conversely, the lowest is -82 dBm. Thus, the results show that the throughput value is 3.97 Mbps. Within the maximum bandwidth of 10 Mbps, the average packet-loss is not more than 3%. The delay measurement provides a result of not more than 100 ms, and the jitter obtained is 0.04. According to the digital floor plan, the calculation results of the coverage area match the signal level measurement.

The placement of a transmitter in a wireless network (access point) is one of the essential things which must be considered by the network designer. The right placement will give the maximum signal spread, especially for the closed environment, because of the effect of the indoor propagation, which affects the signal strength decrease significantly. Every AP’s placement point will have different signal spread pattern, including the coverage area. The AP placement process carried out so far still uses conventional methods, namely trial-error, which requires a long time to analyze its performance. A coverage prediction system modeling is built to determine the spread of signals generated by an AP. This modeling is done using a statistical approach in 2D. The modeling did a visualization that is run through software and gives the result of mapping the coverage area of an AP. The test results show that the percentage of area coverage generated based on the AP placement used is currently 72.5%. There are still areas that are not covered by the AP, especially for the NLOS propagation path because of the obstruction around the AP. The maximum distance between the AP and the user so that it is within the coverage area is 13.21m

The ultradensification deploying for cellular networks is a direct and effective method for the improvement of network capacity. However, the benefit is achieved at the cost of network infrastructure investment and operating overheads, especially when there is big gap between peak-hour Internet traffic and average one. Therefore, we put forward the concept of virtual cellular coverage area, where wireless terminals with high-end configuration are motivated to enhance cellular coverage quality by both providing RF energy compensation and rewarding free traffic access to Internet. This problem is formulated as the Stackelberg game based on three-party circular decision, where a Macro BS (MBS) acts as the leader to offer a charging power to Energy Transferring Relays (ETRs), and the ETRs and their associating Virtual Access Points (VAPs) act as the followers to make their decisions, respectively. According to the feedback from the followers, the leader may readjust its strategy. The circular decision is repeated until the powers converge. Also, the better response algorithm for each game player is proposed to iteratively achieve the Stackelberg-Nash Equilibrium (SNE). Theoretical analysis proves the convergence of the proposed game scheme, and simulation results demonstrate its effectiveness.

Salah satu perubahan yang sangat pesat di dalam jaringan komputer adalah penggunaan wireless LAN (WLAN) untuk mengakses jaringan baik lokal maupun internet. Salah satu cara penambahan Access Point (AP) yang tidak mengubah konfigurasi software yang telah di gunakan yaitu menggunakan jaringan Wireless Distribution System Mesh (WDS). Penggunaan WDS mesh di Universitas Muhammmadiyah Jember memungkinkan konfigurasi wireless yang sedikit berbeda agar dapat mengurangi terputusnya koneksi pada pengguna karena jangkauan area jaringan wireless. Salah satu langkah adalah dengan menggunakan beberapa perangkat Acesss Point menjadi satu kesatuan untuk menangani kasus terputusnya koneksi dengan memanfaatkan service jaringan yaitu WDS Mesh. Wireless Distribution System atau (WDS) Mesh mampu meng- coverage area wifi di Universitas Muhammadiyah Jember dan hasil ujicoba serta analisa device client terhadap AP yang sudah di WDS Mesh dengan parameter Signal Strength, CCQ, Signal to Noise, Throughput adalah Excellent (Bagus)
