"Spektrum frekuensi radio merupakan sumber daya alam yang jumlahnya terbatas. Diperlukan penataan alokasi spektrum secara baik dalam mengoptimalkan penggunaannya, salah satunya adalah frekuensi sharing. Kepdirjen no.119/DIRJEN/2000 Indonesia mengijinkan adanya penggunaan bersama frekuensi 3.5 GHz antara dinas tetap satelit (Fixed Satellite Service) dan layanan akses pita lebar berbasis nirkabel (Broadband Wireless Access). Kurangnya pertimbangan teknis dan ketidaksiapan badan regulasi menyebabkan timbulnya permasalahan interferensi sehingga terjadi kerusakan data dan putusnya layanan FSS. Oleh karena itu, dilakukan revisi terhadap kepdirjen sebelumnya dengan Rancangan Peraturan Menteri Komunikasi Dan Informatika Nomor: /PER/M.KOMINFO/.../2007 yang isi diantaranya, pada pasal 16 ayat 3 menyebutkan bahwa penyelenggara BWA eksisting pada pita frekuensi radio 3.5 GHz wajib migrasi ke pita frekuensi radio 3.3 GHz selambat-lambatnya 2 tahun sejak ditetapkan. Disimulasikan frekuensi sharing 3.5 GHz antara FSS dan BWA dengan software SPECTRAemc untuk daerah Jakarta. Selanjutnya diusulkan teknik mitigasi interferensi yang dapat digunakan agar kedua layanan tersebut tetap beroperasi dengan baik hingga batas dilakukannya migrasi yaitu 2 tahun mendatang.

Radio frequency spectrum is a limited natural resources which needed good management to optimalize its use, one of the way is sharing frequency. No.119/Dirjen/2000 Indonesian kepdirjen permit the co-existence of frequency usage in 3.5 GHz between Fixed Satellite Service and Broadband Wireless Access.

Lack of technical consideration and awareness of national regulator causes interference problems that disrupt FSS services. Therefore, revision has been done to the previous kepdirjen with Number: /PER/M.KOMINFO/.../2007 which one of the content is, section 16 article 3, mention that eksisting BWA organizer at frequency band 3.5 GHz must be migrated to the frequency band 3.3 GHz at the latest 2 year since specified.

Simulated sharing frequency at 3.5 GHz between BWA and FSS with SPECTRAemc software for Jakarta area. Hereinafter proposed the interference mitigation technique that able to be used to ensure both of the services remain to operate well until the next 2 years."

"Implementasi Jaringan Tetap Akses Nirkabel (FWA) sejak tahun 2002 telah meningkatkan penetrasi telepon tetap dari 3 % pada tahun 2002 menjadi 9 % pada tahun 2007. Layanan FWA telah berkembang menjadi layanan yang mirip dengan Layanan Telepon Bergerak Seluler (Layanan Seluler) baik dari segi fitur maupun cakupan geografisnya. Sehingga Layanan FWA dianggap menjadi pesaing langsung Layanan Seluler. Pengenaan BHP Frekuensi kepada Penyelenggara FWA yang jauh lebih rendah dari Penyelenggara Layanan Seluler telah menciptakan kompetisi yang tidak seimbang.Berdasarkan hasil perhitungan tarif pungut Bakrie Telecom dan Telkom FWA terlihat bahwa tarif yang diberlakukan jauh dibawah tarif Layanan Seluler. Namun tarif FWA masih menghasilkan margin keuntungan yang mencukupi dibandingkan dengan penyelenggara telekomunikasi lainnya di Indonesia dan negara lain. Dengan melakukan simulasi kenaikan BHP Frekuensi FWA sampai pada tingkat yang sama dengan Layanan Seluler, ternyata masih menghasilkan margin keuntungan yang baik yang ditunjukkan oleh Margin Laba Operasi sebesar 20 % hingga 34 % dan EBITDA Margin sebesar 38 % hingga 45 % . Sedangkan jika margin keuntungan saat ini tetap dipertahankan, maka akan terjadi kenaikan tarif pungut 6 % sampai 9 %.Berdasarkan hasil simulasi dapat dilihat bahwa kenaikan BHP Frekuensi FWA tidak membawa dampak bisnis yang buruk bagi kondisi penyelenggaraan FWA. Apalagi jika mempertimbangkan pertumbuhan trafik layanan FWA sebesar lebih dari 66 %, pertumbuhan basis pelanggan lebih dari 52 % dan pertumbuhan pendapatan lebih dari 23 %, maka tingkat keuntungan akan terus bertambah. Namun demikian yang lebih penting adalah besaran BHP Frekuensi yang tepat akan menciptakan kompetisi yang seimbang dan mendorong penggunaan frekuensi lebih efisien, sehingga memberikan manfaat yang sebesar ? besarnya bagi masyarakat sebagai stakeholder yang terpenting.

The implementation of Fixed Wireless Access Network (FWA) since 2002 has increased the fixed telephone penetration from 3% in 2002 to 9 % in 2007. The FWA services have been extending to become similar with Cellular Mobile Telephone Services (cellular services) in term of features and geographical coverage. Therefore the FWA services are considered as direct competitor to the cellular services. The much lower frequency usage right fee for FWA providers compared to cellular service providers has created unequal competition.Based on the retail tariff calculation result for Bakrie Telecom and Telkom FWA, the applied rates are much lower than the cellular services rates. However, the FWA services rates are still providing adequate profit margins compared with other telecommunications service providers in Indonesia and other countries. By performing a simulation of raising FWA frequency usage right fee to the same level with cellular services, it still results an adequate profit margins as indicated by operating income margin of 20 % - 34 % and EBITDA Margin of 38 % - 45 %. Whereas if the current profit margin is still maintained, they have to raise retail tariff to 6 % - 9 %.According to the simulation results it can be observed that raising the FWA frequency usage right fee does not cause unacceptable business impact to their service provision. Moreover considering the FWA services traffic growth more than 66 %, the subscriber base growth more than 52 % and the revenue growth more than 23 %, the profit margin will grow continuously. However more importantly, an equitable frequency usage right fee will create a fair competition and promote more efficient frequency usage, so that it will provide maximum benefit to the people being the most important stakeholder."

"This monograph develops a framework for modeling and solving utility maximization problems in nonconvex wireless systems. The first part develops a model for utility optimization in wireless systems. The model is general enough to encompass a wide array of system configurations and performance objectives. Based on the general model, a set of methods for solving utility maximization problems is developed in the second part of the book. The development is based on a careful examination of the properties that are required for the application of each method. This part focuses on problems whose initial formulation does not allow for a solution by standard methods and discusses alternative approaches. The last part presents two case studies to demonstrate the application of the proposed framework. In both cases, utility maximization in multi-antenna broadcast channels is investigated."

"Fixed Wireless Access (FWA) adalah salah satu kasus penggunaan populer di 5G, yang diharapkan dapat menggantikan layanan internet konvensional. Namun, implementasi jaringan telekomunikasi membutuhkan modal besar, sehingga harus dilakukan secara hati-hati untuk meminimalkan resiko. Secara umum, investasi jaringan dinilai dengan metode Net Present Value (NPV) standar. Ketika NPV positif, maka infrastruktur tersebut menguntungkan. Namun, NPV mungkin tidak akan seperti yang diharapkan karena ketidakpastian di masa depan. Salah satunya adalah jumlah pelanggan. Penelitian ini mengusulkan penggunaan Real Option (RO) dengan metode decision tree dan model Black Scholes untuk menganalisis implementasi jaringan FWA di kawasan urban. Dari hasil penelitian, metode NPV standar menghasilkan Expected NPV positif sebesar IDR 2.297.625.000. Namun, terdapat resiko sebesar 33% bahwa NPV akan menjadi IDR -6.093.690.000. Dengan menggunakan decision tree, memiliki pilihan untuk menunda pembangunan FWA selama satu sampai tiga tahun pembangunan FWA dapat dibatalkan apabila menghasilkan NPV negatif dan semua nilai ENPV yang lebih besar daripada tanpa pilihan untuk menunda pembangunan dimana penundaan pembaangunan FWA paling baik dengan pilihan menunda selama satu tahun. Nilai ENPV apabila terdapat pilihan untuk menunda pembangunan FWA yakni IDR 3.750.570.000 ketika menunda selama satu tahun, IDR 3.252.630.000 ketika menunda selama dua tahun, dan IDR 2.825.565.000 ketika menunda selama tiga tahun. Hasil dari metode model Black Scholes juga memiliki nilai ENPV yang lebih besar dari pada tidak memiliki pilihan untuk menunda pembangunan FWA dimana nilai ENPV paling besar apabila pembangunan dapat ditunda selama tiga tahun. Nilai ENPV dari model Black Scholes yakni: IDR 3.310.020.000 untuk penundaan pembangunan selama satu tahun, IDR 3.191.115.150 untuk penundaan pembangunan selama dua tahun, dan IDR 4.654.239.750 untuk penundaan pembangunan selama tiga tahun

Fixed Wireless Access (FWA) is one of the popular use cases in 5G, which is expected to replace conventional internet services. However, the implementation of telecommunications networks requires large capital, so it must be done carefully to minimize risks. In general, network investments are valued by the standard Net Present Value (NPV) method. When the NPV is positive, the infrastructure is profitable. However, the NPV may not be as expected due to future uncertainties. One of them is the number of customers. This study proposes the use of Real Option (RO) with the decision tree method and the Black Scholes model to analyze the implementation of the FWA network in urban areas. From the research results, the standard NPV method produces a positive Expected NPV of IDR 2,297,625,000. However, there is a 33% risk that the NPV will be IDR -6,093,690,000. By using the decision tree, having the option to delay the construction of the FWA for one to three years, the construction of the FWA can be canceled if it produces a negative NPV and still result all ENPV values are greater than without the option to postpone the construction where delaying the construction of the FWA is best with the option of delaying for one year. The ENPV value if there is an option to postpone the construction of the FWA is IDR 3,750,570,000 when delaying for one year, IDR 3,252,630,000 when delaying for two years, and IDR 2,825,565,000 when delaying for three years. The results of the Black Scholes model method also have a greater ENPV value than not having the option of delaying the construction of the FWA where the ENPV value is greatest if the construction can be delayed for three years. The ENPV values of the Black Scholes model are: IDR 3,310,020,000 for a one-year implementation delay, IDR 3,191,115,150 for a two-year implementation delay, and IDR 4,654,239,750 for a three-year implementation delay."
