  • Rancang Bangun dan Pengaruh Kepadatan Traffic terhadap Sistem Pengaman Pintu pada Shelter base Tranceiver station (Bts) Berbasis Android
    Tanjungpura University, 2017
    Co-Authors: Suryanto T. A.
    Abstract:

    Telecommunications developments are accelerating, is evident from the increase in cellular-based communication tools or called by handphone. One of the main components of mobile telecommunications is a base transceiver station (BTS). Shelter BTS built scattered in a network area, have a short long distance , so it requires Android based remote monitoring. In this research will be testing the response time of the hardware to the Android App. In this study using an Arduino Uno R3 as a microcontroller, GSM / GPRS Shield as a modem and use a limit switch sensor as a detector open and close the shelter door. While the application is used in the Arduino IDE and Android Studio. The test results and a discussion of test results obtained the average value of the response time is 6.4 seconds and proved to be faster than a safety device that is currently owned by PT. Hutchison 3 Indonesia Branch Pontianak. In this test performed 10 times at the weekend and workday and proven by statistical analysis using ANOVA single factor. The results of data processing by these statistics showed that the network traffic affect the duration of the response time

  • the energy cost analysis of hybrid systems and diesel generators in powering selected base transceiver station locations in nigeria
    Energies, 2018
    Co-Authors: Peter Ozaveshe Oviroh, Tienchien Jen
    Abstract:

    As more locations gain access to telecommunication, there is a growing demand to provide energy in a reliable, efficient and environmentally friendly manner while effectively addressing growing energy needs. Erratic power supply and rising operation costs (OPEX) in Nigeria have increased the need to harness local renewable energy sources. Thus, identifying the right generator schedule with the renewable system to reduce OPEX is a priority for operators and vendors. This study evaluates the energy costs of hybrid systems with different generator schedules in powering base transceiver stations in Nigeria using the Hybrid Optimization Model for Electric Renewable (HOMER). A load range of 4 kW to 8 kW was considered using: (i) an optimised generator schedule; (ii) forced-on generator schedule and (iii) the generator-only schedule. The results showed an optimal LCOE range between averages of USD 0.156/kWh to 0.172/kWh for the 8 kW load. The percent energy contribution by generator ranges from 52.80% to 60.90%, and by the solar PV system, 39.10% to 47.20%. Excess energy ranges from 0.03% to 14.98%. The optimised generator schedule has the highest solar PV penetration of 56.8%. The OPEX savings on fuel ranges from 41.68% to 47% for the different load schedules and carbon emission savings of 4222 kg to 31,428.36 kg. The simulation results shows that powering base stations using the optimised hybrid system schedule would be a better option for the telecom industry.

  • gsm to umts network handover vulnerability testing using software defined radio
    Hawaii International Conference on System Sciences, 2015
    Co-Authors: Carson Mcabee, Murali Tummala, John Mceachen
    Abstract:

    This paper examines a possible vulnerability with the potential for a malicious entity to prevent a mobile device from handing over from a global system for mobile communications (GSM) to universal mobile telecommunications system (UMTS) network because the GSM network maintains the stand-alone dedicated control channel (SDCCH) uplink time slots. The process of testing this vulnerability requires the development of a device that monitors a GSM base transceiver station, identifies when a handover to UMTS message is sent, tracks the time slots of the SDCCH uplink, and transmits a GSM handover-failure message. We present a scheme that utilizes parts of the Open BTS to transmit a GSM handover-failure message using a software defined radio. The method is validated through the collection of the GSM transmitter messages by Air probe's GSM-receiver module.

  • IMPLEMENTASI MONITORING base transceiver station SYSTEM (BTS) BERBASIS WEB
    'Universitas Islam Kalimantan MAB Banjarmasin', 2018
    Co-Authors: Retnosari Dwi, Setiadi Budi
    Abstract:

    Jaringan BTS (base transceiver station) merupakan bagian terpenting dari PT Telkomsel, data monitoring BTS yang berjalan saat ini masih belum terorganisir dengan baik sehingga masih ada kerusakan fatal pada perangkat BTS yang terjadi karena kurangnya perangkat yang dipantau. Seiring berjalannya waktu, jumlah BTS telah meningkat, untuk mendukung layanan telekomunikasi dan infrastruktur yang memadai. Dengan banyaknya BTS yang ada saat ini perlu diimbangi dengan keberadaan sistem yang dapat memonitor aktivitas yang terjadi pada perangkat ini dengan baik, sehingga potensi kerusakan fatal dapat dihindari. Oleh karena itu, aplikasi ini dimaksudkan sebagai media penyimpanan informasi, pengolahan informasi dan analisis informasi sehingga rekomendasi tentang tindakan pencegahan atau perbaikan yang perlu dilakukan. Dalam penelitian ini memilih sistem berbasis web, sistem dapat diakses dari mana saja.Perangkat lunak yang digunakan untuk mengembangkan sistem ini adalah Macromedia Dreamweaver dan Notepad ++ sebagai media untuk merancang tampilan dan menulis kode program, aplikasi xampp sebagai web server dan mozilla firefox untuk melihat hasil tampilan dengan Sistem Operasi Windows 7. Keywords: base Tranceiver station, Web , Xamp
