Standar jaringan WLAN yang paling banyak beredar dipasaran saat ini adalah IEEE 802.11n. Untuk membangun jaringan WLAN yang lebih praktis dapat menggunakan teknik UR dan WDS.  Penelitian ini bertujuan untuk dapat mengukur dan menganalisa pengaruh jumlah client dan jarak terhadap kualitas jaringan WLAN yang menggunakan teknik UR dan WDS dengan parameter ukur bandwidth, jitter, dan packet loss. Hasil analisa data diketahui bahwa semakin banyak client dan semakin jauh jarak transmisi dapat menurunkan kualitas jaringan UR dan WDS. Kualitas jaringan terbaik dihasilkan jaringan UR pada jarak 7,5m dengan rata-rata bandwidth sebesar 11934.7035 Kbps, rata-rata jitter sebesar 2.3563135 ms, dan rata-rata packet loss sebesar 1.90% dibandingkan jaringan WDS dengan rata-rata bandwidth 3846.9135 Kbps, rata-rata jitter 9.496095 ms, dan rata-rata packet loss 5.23%. Kualitas jaringan terburuk dihasilkan jaringan WDS pada jarak 30m dengan rata-rata bandwidth sebesar 898.32735 Kbps, rata-rata jitter sebesar 37.32591 ms, dan rata-rata packet loss sebesar 47.10% dibandingkan jaringan UR dengan rata-rata bandwidth 8859.797 Kbps, rata-rata jitter 13.082195 ms, dan rata-rata packet loss 19.24%. Hasil keseluruhan pengukuran diketahui bahwa teknik UR lebih unggul dibandingkan WDS dalam membangun jaringan WLAN.   KATA KUNCI : WLAN (Wireless Local Area Network), UR (Universar Repeater), WDS (Wireless Distribution System), Bandwidth, Jitter, Packet Loss

The Impact

The IEEE 802.11n supports high data rate transmissions due its physical layer Multiple Input ‎Multiple Output (MIMO) advanced antenna system and MAC layer enhancement features (frame ‎aggregation and block acknowledgement). As a result this standard is very suitable for multimedia ‎services through its Enhanced Distributed Channel Access (EDCA). This paper focuses on ‎evaluating the Quality of Service (QoS) application on the performance of the IEEE 802.11n ‎random topology WLAN. Three different number of nodes (3, 9 and 18) random topology with one ‎access point are modeled and simulated by using the Riverbed OPNET 17.5 Modular to ‎investigate the Wireless Local Area Network (WLAN) performance for different spatial streams. ‎The result clarified the impact of QoS application and showed that its effect is best at the 18 node ‎number topology. For a 4x4 MIMO, when QoS is applied and with respect to the no QoS ‎application case, simulation results show a maximum improvement of 86.4%, 33.9%, 52.2% and ‎‎68.9% for throughput, delay, data drop and retransmission attempts, respectively. ‎

Wireless Communications Systems

Wireless local area network (WLAN) is the core of the classic wireless communications systems and owns the infrastructure which wide spreads in many regions in the world. IEEE 802.11n is an attractive standard of WLAN and offers a data capacity of the cell. This paper estimates the maximum limits of the IEEE 802.11n standard cell as a term of number of users which are successfully served by the cell in case of video conference application. The results shown that, the cell of 802.11n could serve about 9 users under the service of video conference in case of 20MHz channel bandwidth before congestion occurs while the 40MHz channel could support 18 users.

Now a days in Wireless Local Area Networks (WLANs) used in different fields because its well-suited simulator and higher flexibility. The concept of WLAN  with  advanced 5th Generation technologies, related to a Internet-of-Thing (IOT). In this project, representing the Network Simulator (NS-2) used linked-level simulators for Wireless Local Area Networks and still utilized IEEE 802.11g/n/ac with advanced IEEE 802.11ah/af technology. Realization of the whole Wireless Local Area Networking linked-level simulators inspired by the recognized Vienna Long Term Evolution- simulators. As a outcome, this is achieved to link together that simulator to detailed performances of Wireless Local Area Networking with Long Term Evolution, operated in the similar RF bands. From the advanced 5th Generation support cellular networking, such explore is main because different coexistences scenario can arise linking wireless communicating system to the ISM and UHF bands.
