Abstract

Data security on cellular networks is needed to maintain privacy and avoid illegal actions, because the process of communication and sending data remotely using cellular networks, especially GSM and GPRS are still widely used than conventional methods. One of the potential for sniffing data security holes can occur in the air interface, it is signalling system when transmitting data between user devices or Mobile Station (MS) and Base Transceiver Station (BTS). Therefore, to find out the quality of data security on GSM and GPRS cellular networks, a penetration testing method with RTL-SDR device are tested. The results obtained are the cellular network security system used is still secure based on data transmission patterns using timeslot, Temporary Mobile Subscriber Identity (TMSI), and changes in GSM Frame Number on GSM. Then, network security on GPRS is also still safe using logic channels, timeslot, and different security algorithm from GSM.

Abstract

Low Power Wide Area Networks (LPWAN) is a wireless communication technology that supports the development of the Internet of Things (IoT). LPWAN offers a wider coverage area and low energy consumption. LoRa is one of the most popular LPWAN technologies. LoRa technology is suitable for IoT application scenarios that only need to send small amounts of data over long distances and low-power transmission data. This research focuses on testing the range of the LoRa Rfm 95/96 chip at 920 MHz and SF7 frequencies for urban areas. The parameters used are Received Signal Strength Indicator (RSSI) and Packet loss. RSSI test results will be compared with RSSI calculation results using the log normal shadowing model. The RSSI value of the test results is closer to the calculation of the RSSI value for the free space area with the addition of a shadowing effect. When viewed from the range of RSSI values ​​at each test point, RSSI is relatively stable. However, based on RSSI average testing and calculation, RSSI has decreased while packet loss has increased with each additional distance. From this study, the maximum LoRa range is 2 km. This is in line with LoRa specifications for urban areas.

Abstract

Navigation technology has become an important component in everyday life, the development of the Internet of things (IoT) technology increases with the human need for a system that can work reliably in making work easier. The purpose of this study is to produce a simple tracking system that can be used on mobile vehicles or public transportation so that it helps the public to receive information about the position of public transportation so as to make time efficient, can also be used as a security system on private vehicles. Previously, the Tracker Development used WiFi technology or sim module, the WiFi range was considered to be very small, less than 50m and the sim module was less efficient therefore there must be renewed. This system was built using the ESP32 microcontroller and the LoRa Antares communication system. it works on the 920-923 MHz channel frequency. This system works with the GPS module as a receiver for position information based on triangulation of several satellites in space, devices that are within the reach of the LoRa gateway will send data to the web server antares. Then the data is processed and displayed visually to the dashboard. The average shipping delay is 1.1 seconds, the maximum delay is 8 seconds, the minimum delay is 0 seconds, packet loss is 23%, the maximum radius is 2.16KM. Data was collected at PT Telkom DDS Gegerkalong Hilir, Bandung.
