In this modern era, the development of technology in the field of telecommunications is growing rapidly, especially with the needs of the global situation that relies more on long-distance communication. One of these developments is the emergence of the Raspberry Pi (Raspi) which is a single-board circuit (SBC) computer capable of being used as a medium for teleconferences, offices, Big Data, and high-resolution video players. The Raspberry Pi has advantages that resemble computers in general, everything in computer functions can also be done with the Raspberry Pi, but the Raspberry Pi has the advantage of being mini and portable. This study proposes the application of the Raspberry Pi 3b+ as a receiver for FM radio waves at a frequency of 87.9 MHz and 105.3 MHz using an RTL-SDR 2832U connected to a dipole antenna. The author uses signals from radio stations as transmitters of FM waves at frequencies of 87.9 MHz and 105.3 MHz. The implementation of the Raspberry Pi as an FM receiver in this study uses RTL-SDR 2832U with GNU Radio and GQRX software. The operating system used in this research is Raspberry Pi OS. The results show that the Raspberry Pi device can be used to receive FM waves at a frequency of 87.9 MHz and 105.3 MHz. The dipole antenna tested using VNA (Vector Network Analyzer) with a length of 81 cm for a frequency of 87.9 MHz and 66 cm for a frequency of 105.3 MHz and a linear antenna shape that can transmit signals with a VSWR of 1.29:1 at a working frequency of 87.96 MHz with a Return Loss of -23. dBm and 6 MHz bandwidth for 87.9 MHz frequency and 1.29:1 VSWR at 105.3.16 MHz working frequency with -29 dBm Return Loss and 8.4 MHz bandwidth for 105.3 MHz frequency.

Telecommunications network technology has entered the fifth generation or often called 5G NR. The availability of 5G NR network services is expected to be a solution to improve the quality of telecommunication networks in Malang City. The research in this thesis plans a 5G NR network at a frequency of 28 GHz and a bandwidth of 100 MHz, by analyzing the needs of gNodeB in Malang City and user projections from 2020 to 2025. The methods of analyzing the needs of gNodeB discussed are coverage dimensioning and capacity dimensioning. From the analysis day, the predicted number of people using the 5G NR network in 2025 is 378,052 people. The number of gNodeB needed is based on the calculation of coverage dimensioning as much as 921 gNodeB and Capacity dimensioning of 74 gNodeB. The planning results are simulated on the Atoll software. Where obtained the placement of 74 gNodeB in the Malang City area has been able to serve users. Keywords –5G, coverage dimensioning, capaity dimensioning, 28 GHz, ATOLL.

The development of technology, especially in the field of wireless communication, has developed quitte rapidly. Software Defined Radio (SDR) technology is one of the births of wireless communication technology which is a new challenge for communication engineers. The development of SDR systems has made significant progress in recent years because these systems have the ability to improve the quality of previous analog radio communications and can be used as a replacement for hardware implementations. SDR can be used when redesigning a radio software system where later the parameters can be changed to get the desired quality using the existing codes. To be able to solve code and process radio signals required hardware such as computers to support SDR technology. An application that runs inside GNU Radio by construct block. So the purpose of this thesis is to determine the frequency allocation of FM radio stations that are used in an area at the same time. The design of the spectrum analyzer in this thesis is based on SDR using an RTL-SDR type 2832U dongle. This spectrum research used RTL-SDR, suggested improvements such as the need for an increase in the RTL-SDR specifications used in this thesis, need to do research and design using other SDR and it is necessary to add facilities by setting the resolution bandwidth to determine the level of some radio signals.Index Terms – RTL-SDR, GNU Radio, Spectrum Analyzer

In recent years, technology in the telecommunications sector has developed rapidly, especially with the global situation encouraging the use of long-distance communications. One of these developments is the use of the Raspberry Pi, abbreviated as Raspi, as a substitute for conventional computers for receiving and transmitting FM radio signals. Raspberry Pi is a mini and portable computer that can be used as an alternative to conventional computers in general, such as the use of teleconference media, offices, Big Data, and as a video player with high resolution. The problem in using a computer as an FM radio signal transceiver system is its complex and expensive infrastructure. When compared to the Raspberry Pi 3 with a price range of IDR 500,000 - IDR 1,000,000, a transceiver system using conventional computers requires a computer in general at a price far exceeding the said price. Using Raspi makes it easy to transmit FM radio signals by simply coding through the Raspi terminal. In this study, the authors propose a transmitter system using a Raspberry Pi 3B+ which is connected to a dipole antenna at a working frequency of 100 – 101 MHz. Raspi is operated using the SSH protocol for remote desktops. The operating system used is Raspberry Pi OS with the use of a MAC computer (MAC OS) as a remote desktop. The results show that the Raspberry Pi device can be used to transmit FM radio signals at a frequency of 100 - 101 MHz. The dipole antenna tested using VNA (Vector Network Analyzer) with a length of 71 cm and a linear form can transmit a signal with a VSWR of 1.08 - 1.95:1 at a working frequency of 94.9 - 103.06 MHz and a return loss of -28.1 dBm at a frequency of 98.98 MHz.
