ABSTRAK Penggunaan jaringan wireless sebagai salah satu penunjang dalam kegiatan belajar mengajar sudah tidak asing lagi. Karena pada zaman sekarang dimana pencarian informasi yang begitu mudah dan cepat dengan adanya bantuan jaringan wireless . Pada gedung A Teknik Elektro Universitas Brawijaya terdapat 4 buah access point standar IEEE 802.11n. Namun implementasi yang ada perlu dilakukan evaluasi agar dapat diketahui kualitas staandar jaringan wireless 802.11n apakah sudah sesuai standar yang berlaku. Evaluasi dapat menggunakan aplikasi NetSpot karena dapat memindai seluruh area gedung A yang terpasang access point dan dapat menampilkan parameter kualitas jaringan seperti level sinyal, SIR ( Signal to Interference Ratio ), dan manajemen kanal. Hasil penelitian menunjukkan bahwa parameter yang didapat masih menunjukkan nilai yang jauh dari standar jaringan wireless IEEE 802.11n dengan nilai level sinyal -81 dbm, -85 dBm, dan -96 dBm. Serta nilai SIR yang didapat sebagai acuan adanya...

Access point (AP) is part of a Wireless Local Access Network (WLAN) with its communications using WiFi. AP is used to transmit and receive data to users/clients. The ability of AP to serve users/clients depends on many factors. Moreover, if AP is applied in conditions inside the building. In this study, AP is installed at two points inside the building and then measured in the form of the received signal level (RSL) and service coverage area. One AP measured its performance by 26 measurement points and the other AP measured its performance by 20 measurement points. When AP has measured its performance then another AP position is switched off. Based on the measurement result, the received signal level value is the highest value is about-47 dBm at a distance of 3.2 m, while the lowest is about-79 dBm at a 9.21 m because it is on barrier 2 walls. While based on service coverage area, the area which is far away from the AP then the quality of service becomes bad because the transmitted signal is weakening caused by the distance and the loss of the wall.
Performance analysis of IEEE 802.11ac based WLAN in wireless communication systems
International Journal of Electrical and Computer Engineering (IJECE), 2019
IEEE 802.11ac based wireless local area network (WLAN) is emerging WiFi standard at 5 GHz, it is new gigabit-per-second standard providing premium services. IEEE 802.11ac accomplishes its crude speed increment by pushing on three distinct measurements firstly is more channel holding, expanded from a maximum of 80 MHz up to 160 MHz modes. Secondly, the denser modulation, now using 256-QAM, it has the ability to increase the data rates up to 7 Gbps using an 8×8 multiple input multiple output (MIMO). Finally, it provides high resolution for both narrow and medium bandwidth channels. This work presents a study to improve the performance of IEEE 802.11ac based WLAN system. 1. INTRODUCTION Recently, wireless communications have fundamentally developed because of the trend setting innovation of cell phones, convenient gadgets and the fast development of Internet of Things (IOT) [1], astute transportation frameworks and person to person communication. IEEE 802.11 is a well-known standard that widely used to control the physical layer determinations for executing wireless local area network (WLAN) computer for various frequency bands such as 900 MHz and 2.4, 3.6, 5, and 60 GHz [2]. At 1997 the basics of IEEE 802.11 was discharged and then the results were revised. This system with its corrections are focusing on the items of wireless systems such as Wi-Fi. On the other hand, every modification is revoked when it is established in the last version of the system. The companies resort to market to get the corrections and updates in order to improve the capabilities of products. These revised systems will become new standards. Wireless communications heading towards high bandwidth of data transmission for multi-users at the same time. IEEE 802.11 standards evolution is shown in Figure 1. This paper introduces the history of IEEE 802.11 standard in section 2. While section 3 presents how IEEE 802.11 developped and improved to IEEE 802.11ad.The simulation results with detailed discussions are presented in section 4. Finally, the important conclusions and some suggestions for further improvement of the proposed work are discussed in section 5.
WLAN IEEE 802.11 a/b/g/n Indoor Coverage and Interference Performance Study
2011
An adequate wireless network plan is needed to replace the traditional wired LANs. A full coverage WLAN offers the flexibility to relocate people and equipment or to reconfigure and add more wireless devices to the network. Usually, an IEEE 802.11 variant is chosen based on their bandwidth and their coverage area. However, sometimes there are special cases where the best technology is not the newest one. In addition, suitable positioning of access points (AP) is crucial to determine the efficiency of the network. E.g. in the case where devices are going to transmit at a maximum of 1 Mbps, any choice is acceptable, but when it is required higher performance, other factors must be considered. In this paper, we compare IEEE 802.11a/b/g/n indoor environments to know what technology is better. This comparison will be taken in terms of RSSI, coverage area, and measuring the interferences between channels. These key factors must be optimum to have high performance in the WLAN. This study will help the researchers to choose the best technology depending of their deploying case, and we will see study the best variant for indoors.

This paper reports the experimental results of IEEE 802.11b wireless link performance in ad hoc mode. The throughput and packet loss rate are measured for User Datagram Protocol (UDP) and Transmission Control Protocol (TCP) traffic in both indoor and outdoor environments. Various factors that affect the performance of the wireless link, such as the packet size, the transmission rate, the distance between stations, the retry limit and the network topology are considered. Experimental measurements are also compared against theoretical calculations.
