"Saat ini telah berkembang teknologi Worldwide Interoperability for Microwave Access (WIMAX) yang merupakan teknologi Broadband Wireless Access (BWA), untuk komunikasi broadband yang memiliki kecepatan akses tinggi dan jangkauan yang luas. WIMAX merupakan standar internasional Broadband Wireless Access (BWA) yang mengacu pada standar IEEE 802.16. Saat ini, Rancangan Peraturan (RPM) Menteri Komunikasi dan Informatika tentang penataan pita frekuensi radio untuk keperluan layanan akses pita lebar berbasis nirkabel (Broadband Wireless Access), sedang dalam proses penyusunan dan penyempurnaan. Penelitian yang dilakukan terhadap RPM ini meliputi pita frekuensi radio 2.3 GHz, 2.5 GHz, 3.3 GHz dan 5.8 GHz.Metodologi penelitian yang digunakan adalah melalui survey ke operator BWA, wawancara dengan pihak yang terkait BWA, daftar pustaka dan Internet browsing. Hasil dari penelitian ini diharapkan dapat memberikan usulan yang membangun dan berdaya guna dalam rangka penyempurnaan Rancangan Peraturan Menteri Komunikasi dan Informatika tentang penataan pita frekuensi radio untuk keperluan layanan akses pita lebar berbasis nirkabel (Broadband Wireless Access).

At this moment, it has been developed World wide Interoperability for Microwave Access (WIMAX) technology which is Broadband Wireless Access (BWA) technology for broadband communication having high access speed and wide scopes. WIMAX is an international standard of Broadband Wireless Access (BWA) having a reference IEEE 802.16 standard. At this moment, Plan of Ministerial Regulation of Communication and Information about Codes of radio frequency bands for Broadband Wireless Access services is formulating and completing. The research done to Plan of Ministerial Regulation covers 2.3 GHZ, 2.5 GHz, 3.3 GHz and 5.8 GHz radio frequency band.Methodology of research used is through surveys to BWA operators, interviews with parties related to BWA, bibliography and internet browsing. The result of this research is expected to give a developed and useful proposal in the framework of completing for Plan of Ministerial Regulation of Communication and Information about Codes of radio frequency bands for Broadband Wireless Access services."

"WLAN and WiMAX frame structures are preceded by preamble signals. They have some similarities such as consisting of two adjacent signals with repetition patterns. Therefore, this paper introduces a joint detection of WLAN and WiMAX preambles using a common circuit. Time domain detection is proposed in order to avoid FFT involvement that can increase the system complexity and latency. The proposed system is constructed from repetition based auto-correlation and cross-correlation with resources sharing that has lower complexity than the conventional one. Moreover, the fixed point simulation shows that the proposed circuit has satisfied the receiver minimum sensitivity requirements for both WLAN and WiMAX standards."

"Antena menjadi salah satu komponen penting dalam mendukung penerapan teknologi BWA. Antena mikrostrip yang memiliki karakter yang ringan, ukuran kecil, mudah difabrikasi dan conformal, menjadi pilihan untuk mendukung aplikasi BWA yang dapat beroperasi pada frekuensi yang ditentukan. Salah satu alokasi frekuensi yang dijadikan frekuensi kerja BWA adalah pada 2,3 GHz.Pada tesis ini dirancang dan difabrikasi sebuah antena linear array 4 elemen yang dapat beroperasi pada frekuensi kerja BWA 2,3 GHz. Antena ini dirancang berbentuk 2 buah segi empat sama sisi (quad), sehingga disebut biquad. Antena dirancang menggunakan teknik pencatuan aperture-coupled untuk mendapatkan bandwidth yang lebar. Hasil pengukuran menunjukkan bahwa antena ini dapat bekerja pada frekuensi BWA 2,3 GHz. Nilai VSWR < 1,9 diperoleh pada rentang frekuensi 2245 - 2395 MHz (150 MHz). Gain yang diperoleh mencapai 13,683 dBi pada frekuensi 2,33 GHz dan half power beamwidth (HPBW) sebesar 50° diperoleh pada sudut 330° - 20°.

Antenna became one of the important components in supporting the application of BWA technology. Microstrip antenna that have small and light weight features, easy to manufacture and conformal, became the choice that supports the BWA application in that it could operate in the determined frequency allocation. One of the allocation of the frequency that works for the BWA is at 2.3 GHz.

This thesis discuss of design a 4 element linear array antenna that operates at 2,3 GHz BWA frequency allocation. It has 2 layers of four-sided (quad) shape, known as biquad. This antenna is designed with aperture-coupled feed to give wideband frequency.The measurement result shows that this antenna operates at BWA frequency allocation of 2,3 GHz. The VSWR < 1,9 was obtained at 2245 ? 2395 MHz (150 MHz). Gain is around 13,683 dBi at 2,33 GHz and half power beamwidth is 50° (from 330° - 20°)."

"Teknologi worldwide interoperability for mobile access (WiMAX) mampu mentransfer data dengan kecepatan tinggidan cakupan area yang luas. Teknologi WiMAX telah dikembangkan lagi menjadi teknologi untuk komunikasi bergerakyang dinamakan mobile WiMAX sesuai standar IEEE 802.16e dengan frekuensi kerja 2,3–2,4 GHz. Bandpass filter(BPF) digunakan untuk menyeleksi frekuensi berdasarkan spesifikasi standar WiMax yang telah ditetapkan agar tidakterjadi gangguan dengan channel lain saat melakukan komunikasi. Perancangan BPF menggunakan filter aktifmikrostrip Hairpin dengan rangkaian resistansi negatif. Rangkaian resistansi negatif berfungsi untuk mengkompensasirugi resistansi parasitik yang ditimbulkan dari komponen induktor kapasitor dan menggunakan komponen aktif bipolarjunction transistor (BJT) BFR-183. Penggunakan filter aktif mikrostrip hairpin mempunyai keuntungan yaitu ukuranmenjadi lebih kecil, rugi-rugi yang diakibatkan adanya resistansi parasitik menjadi lebih rendah sehingga faktor Q dapatditingkatkan dan dapat diterapkan pada frekuensi tinggi. Substrat PCB yang digunakan FR4. Hasil simulasi yang diperlihatkan yaitu jalur frekuensi dioperasikan pada 2,3-2,4 GHz, return loss, insertion loss, dan VSWR."

"Thushara Weerawardane introduces new transport technologies and features for High Speed Packet Access (HSPA) and Long-Term Evolution (LTE) networks. Using advanced scientific methods, he proposes new adaptive flow control and enhanced congestion control algorithms, then defends them with highly-developed analytical models derived from Markov chains. For faster analysis, compared to long-lasting detailed simulations, these models provide optimum network performance and ensure reliable quality standards for end users during transport network congestion. Further, the author investigates and analyzes LTE transport network performance by introducing novel traffic differentiation models and buffer management techniques during intra-LTE handovers."
