Extensible Authentication Protocol

Extensible Authentication Protocol (EAP) is authentication method to protect wireless local area network from un-authorized user which there was interaction between radius servers, access point and client device. When EAP was used as authentication method, the authentication can be strengthened by using TLS (Transport Layer Security) certificate where client device and server will use certificate to verify the identity of each other. The certificate must meet requirement on the server and client for the successful authentication. For this time, the authentication method provides highest level for security in wireless local area network because this method can protect man-in-middle vulnerability.The proposed framework is evaluated by using scenario in testing and live environment to ensure that the authentication has been securely for mutual device authentication.

WiFi bekerja pada band 2,4 GHz dan 5 GHz. Standar WiFi yang bekerja pada frekuensi ini antara lain IEEE802.11g dan IEEE802.11a. Pada penelitian ini dilakukan pengukuran terhadap transfer rate download dan upload data dengan standar IEEE802.11g dan IEEE802.11a. Pengukuran dilakukan pada kanal Line of Sight (LOS), menggunakan dua buah laptop yang dihubungkan dengan Access Point (AP) standar IEEE802.11g dan IEEE802.11a.  Hasil penelitian diperoleh, pada standar IEEE802.11g, transfer rate download dan upload data tertinggi 2.662,54.KB/s dan 2.549,60 KB/s, dan terendah 484,50.KB/s dan 477,40 KB/s, sedangkan pada standar IEEE802.11a, transfer rate download dan upload data tertinggi 8.104,68 KB/s dan 5.744,24 KB/s, dan terendah 872,24 KB/s dan 465,38.KB/s. Pada standar IEEE802.11g, transfer rate download dan upload data pada sinyal terendah hingga di bawah 35% dan 30%, dari transfer rate download dan upload data tertinggi. Pada standar IEEE802.11a, transfer rate download dan upload data pada kualitas sinyal terendah hingga di bawah 20% dan 30%, dari transfer rate download dan upload data tertinggi. Kemampuan transfer rate download data Standar IEEE802.11a, 2–3 kali lebih baik pada kondisi kualitas sinyal tertinggi, dan tidak lebih dari 2 kali pada kondisi kualitas sinyal terendah, dibandingkan kemampuan transfer rate download data standar IEEE802.11g. Kemampuan transfer rate upload data Standar IEEE802.11a, 1,4–3 kali lebih baik pada kondisi kualitas sinyal tertinggi, dan 1-3 kali lebih baik pada kondisi kualitas sinyal terendah, dibandingkan kemampuan transfer rate upload data standar IEEE802.11g.

Wireless Local area Network  (WLAN) suatu jaringan area lokal tanpa kabel yang menggunakan frekuensi radio sebagai media transmisinya. Dalam penelitian ini merancang sebuah jaringan wifi di Perumahan Dosen Politeknik Negeri Sriwijaya, yang pancaran wifinya dari kampus Politeknik Negeri Sriwijaya, sehingga Perumahan Dosen dapat mengakses wifi tanpa perlu datang ke kampus. Sebagai receiver komunikasi wifi diperlukan peranan antena dalam sistem komunikasi tanpa kabel (wireless) dengan jarak jauh, antena yang digunakan adalah antena yagi yang bekerja pada frekuensi 2400 MHz. Antena yagi dipilih karena sifatnya yang directional atau pola pancarannya yang terarah. Dalam perancangan antena yagi untuk ukuran reflector, driven, director dan balun dibantu dengan software yagi calculator serta disimulasikan dan diuji  menggunakan MMANA-GAL untuk menghasilkan parameter antena yang lebih akurat. Antena yagi ini kemudian akan dihubungkan dengan access point yang disetup sebagai client untuk menerima sinyal dari transmitter dan router sebagai proses routing agar user di Perumahan Dosen dapat mengakses wifi tersebut. Berdasarkan hasil pengujian MMANA-GAL antena yagi dengan frekuensi 2400 MHz, diperoleh Standing Wave Ratio (SWR) sebesar 1.16 dan Penguatan (Gain) sebesar 14,59 dB.

In this paper, a hybrid of T-dipole and quasi-Yagi antenna is presented for using in dual-band Wireless Local Area Network (WLAN) access point. The antenna is made up of combination of T-dipole and quasi-Yagi antenna structures, which are distinctly designed to operate at 2.4 and 5.5 GHz frequency bands. A simply integrated balun that consists of a curved microstrip line and a circular slot to allow broadband characteristic is used to feed the antenna. The final antenna design presents measured bandwidths (RL ≤ − 10 dB) of 2.35 – 2.55 GHz and 4.30 – 6.56 GHz which cover completely the two bands of WLAN. Simulated and measured results of peak gain and radiation patterns in both E- and H-plane validate potential of the design.

One Step

One very rapid change in computer networks is the use of Wireless Local Area Network (WLAN) to access systems both locally and the internet. One way to add an Access Point (AP) so as not to change the configuration of the running software is use the Wireless Distribution System Mesh (WDS) network. The use of WDS mesh at Universitas Muhammmadiyah Jember (UM Jember) enables a slightly different wireless configuration to reduce the connection loss in the user due to the wireless network area coverage. One step is use AP devices into one unit to handle the case of a connection break by utilizing a network service that is WDS Mesh. WDS Mesh can cover Wi-Fi areas at UM Jember, and the results of testing and analysis of client devices for APs that have been configured WDS Mesh with parameters Signal Strength, CCQ, Signal to Noise Ratio Ratio, Throughput is Excellent.
