Perencanaan Jaringan UMTS pada Frekuensi 900 MHz Studi Kasus Area Yogyakarta

ABSTRAKSI: Teknologi Universal Mobile Telecommunication system (UMTS) yang sudah ada di Indonesia menggunakan alokasi frekuensi 2100 MHz. Dalam penggunaan frekuensi tersebut, jangkauan coverage UMTS sangat kecil sehingga kurang efisien dalam penggunaan Node B, dan kurang cocok diterapkan pada daerah suburban dan kota kecil yang jarang penduduknya. Sehingga dalam perencanaan perlu diterapkan teknologi UMTS dengan frekuensi yang lebih rendah, agar jangkauan coverage menjadi semakin luas dan lebih efisien dalam jumlah Node B yang digunakan, khususnya pada daerah suburban. Dalam penerapan teknologi UMTS, tidak bisa lepas dari teknologi GSM yang telah diterapkan sebelumnya. Oleh karena itu perlu dilakukan studi tentang jaringan eksisting GSM dan UMTS 2100 MHz dan perencanaan yang jaringan akses dari UMTS Pada Tugas akhir dibahas tentang proses perencanaan jaringan UMTS frekuensi 2100 MHz yang meliputi, perencanaan jaringan akses UMTS pada frekuensi 900 Mhz area Yogyakarta, perencanaan scrambling code dan perencanaan link transmisi. Perencanaan jaringan akses meliputi perhitungan link budget, perhitungan kebutuhan trafik, perhitungan radius Node B, serta penempatan Node B pada jaringan existing dan simulasi kualitas sinyal berdasarkan coverage. Dalam proses penyusunan Tugas akhir ini dikumpulkan data lapangan seperti: jumlah penduduk, kondisi geografis daerah dan jaringan eksisting yang berguna dalam tahap dimensioning. Tugas akhir ini menghasilkan suatu detail perencanaan tentang penerapan jaringan UMTS frekuensi 900 MHz di PT. Telkomsel Yogyakarta. Diharapkan Tugas Akhir ini bisa menjadi acuan untuk menerapkan jaringan UMTS frekuensi 900 MHz di Indonesia.Kata Kunci : UMTS 900ABSTRACT: Universal Mobile Telecommunications System (UMTS) Technology is a third generation mobile communications technology. UMTS technology that has been developed in Indonesia using the 2100 MHz frequency allocation. In the use of these frequencies, the range is so small that UMTS coverage is less efficient in the use of Node B, and less suitable to be applied in suburban areas and small towns are sparsely populated. Thus, in planning the UMTS technology should be applied with a lower frequency, in order to reach a wider coverage and more efficient in the number of Node B is used, especially in suburban areas. In the implementation of UMTS technology, can not be separated from the GSM technology that has been applied previously. Therefore it needs to do a study on the existing network of GSM and UMTS 2100 MHz and planning of UMTS access network. In the final discussion about the planning process of UMTS networks include the frequencies 2100 MHz, UMTS access network planning at a frequency of 900 MHz area of Yogyakarta, scrambling code planning and planning of the transmission link. Access network planning including link budget calculation, the calculation of traffic demand, the calculation of radius of Node B, Node B and placement on existing networks and simulation based on the signal quality of coverage. In preparing this final project collected field data such as population, geographic conditions and existing network is useful in the dimensioning phase.This final project is to produce a detailed plan regarding the implementation of 900 MHz UMTS networks in PT.Telkomsel Yogyakarta. It is expected that this Final may be a reference for implementing UMTS network at frequency of 900 MHz in Indonesia.Keyword: UMTS 90

Prospects of the 3G Mobile Networks in Greece (Proc. IST Mobile & Wireless Telecommunications Summit 2002, pp 557-561 16-19 June, Thessaloniki, Greece)

This paper analyses the financial impact of the deployment and operation of the UMTS networks on Greek mobile operators. A Greek incumbent operator with market share 30% throughout the ten-year period of the study has been examined. The methodology and the tool developed in ACTS- TERA and IST-TONIC projects have been utilized for this case study. Initial economic conclusions have been derived, presented and discussed using key profitability factors such us Net Present Value (NPV), Internal Rate of Return (IRR) and payback period. The techno-economic evaluation is followed by a sensitivity analysis in order to identify the impact of the most important parameters such us UMTS penetration, market share, tariff level and usage level.telecommunications, 3G mobile networks, UMTS, technoeconomics

Intersystem soft handover for converged DVB-H and UMTS networks

Digital video broadcasting for handhelds (DVB-H) is the standard for broadcasting Internet Protocol (IP) data services to mobile portable devices. To provide interactive services for DVB-H, the Universal Mobile Telecommunications System (UMTS) can be used as a terrestrial interaction channel for the unidirectional DVB-H network. The converged DVB-H and UMTS network can be used to address the congestion problems due to the limited multimedia channel accesses of the UMTS network. In the converged network, intersystem soft handover between DVB-H and UMTS is needed for an optimum radio resource allocation, which reduces network operation cost while providing the required quality of service. This paper deals with the intersystem soft handover between DVB-H and UMTS in such a converged network. The converged network structure is presented. A novel soft handover scheme is proposed and evaluated. After considering the network operation cost, the performance tradeoff between the network quality of service and the network operation cost for the intersystem soft handover in the converged network is modeled using a stochastic tree and analyzed using a numerical simulation. The results show that the proposed algorithm is feasible and has the potential to be used for implementation in the real environment

Wireless communication, identification and sensing technologies enabling integrated logistics: a study in the harbor environment

In the last decade, integrated logistics has become an important challenge in the development of wireless communication, identification and sensing technology, due to the growing complexity of logistics processes and the increasing demand for adapting systems to new requirements. The advancement of wireless technology provides a wide range of options for the maritime container terminals. Electronic devices employed in container terminals reduce the manual effort, facilitating timely information flow and enhancing control and quality of service and decision made. In this paper, we examine the technology that can be used to support integration in harbor's logistics. In the literature, most systems have been developed to address specific needs of particular harbors, but a systematic study is missing. The purpose is to provide an overview to the reader about which technology of integrated logistics can be implemented and what remains to be addressed in the future

Advanced Positioning and Location based services in 4G Mobile-IP Radio Access Networks

2004 IEEE 15TH IEEE International Symposium on personal, indoor and mobile radio communications (PIMRC 2004), Barcelona, Spain, 5-8 september 2004.This paper proposes an evolved architecture from 3G networks to provide basic and advanced positioning methods for location based services in mobile IPv6-based radio access networks. We start analyzing current status of location-based services (i.e. LBS or LCS) and architectures in 3G networks as well as state-of-the-art research on LBS and mobile Internet. Next we set the requirements the solution should fulfill. We continue proposing the evolved architecture for support of basic and advanced positioning methods, using MIPv6 and HMIPv6 as mobility scenario for the mobile IPv6 based RAN, describing element's functions and changes from current approaches as well as description of the dynamic behavior. We complete the proposal with a bandwidth analysis of the signaling, identifying issues when planning implementation of LCS services in the network
