Mobile phone tracking is a technique that uses various technologies to determine the geographical location of a mobile device[1]. This tracking can be done through network-based tecnologia[2], which uses the mobile network infrastructure to determine the device’s location. Handset-based technology uses software installed on the device and GPS signals to pinpoint location. SIM-based technology uses raw radio measurements from the device’s SIM card, while Wi-Fi-based technology uses Wi-Fi data for location identification. A hybrid positioning system can combine these methods for increased accuracy. However, the use of mobile phone tracking raises significant privacidade[3] and legal concerns. Many countries, particularly in Europe, have strict laws protecting location data and the privacy of individuals. Despite the benefits of mobile phone tracking, such as aiding in navigation or emergency services, it’s important for users to be aware of potential privacy implications.

Definições de termos
1. mobile device. Mobile devices are dynamic tools that offer a broad spectrum of functionalities and applications across various industries. Defined by their portability, these devices range in size from pocket-friendly gadgets to larger equipment. Their physical aspects, including dimension and weight, allow for easy attachment to different host devices and mobility across diverse settings. Despite their portability, wireless connectivity is not a prerequisite. Mobile devices can access networks through both wired and wireless connections, and some even operate without internet connectivity. They are integral in numerous industries, providing solutions for field management, real-time conferencing, asset tracking, and more. However, their application in sectors such as gambling and adult entertainment has prompted regulatory scrutiny. Additionally, they are increasingly used in military operations for training and educational purposes.
2. tecnologia. A tecnologia, derivada das palavras gregas que significam ofício e conhecimento, é um termo amplo que se refere às ferramentas, máquinas e sistemas desenvolvidos pelo homem para resolver problemas ou cumprir objectivos. Com origem em ferramentas primitivas como os machados de pedra e a descoberta do fogo, a tecnologia evoluiu significativamente ao longo da história da humanidade. Foi fundamental em diferentes épocas, desde a invenção da roda e dos sistemas avançados de irrigação nas civilizações antigas até ao nascimento das universidades e da imprensa durante os períodos medieval e renascentista. A Revolução Industrial, no século XVIII, marcou uma mudança significativa na produção em massa e na inovação, dando origem a tecnologias modernas como a eletricidade, os automóveis e as plataformas de comunicação digital. Hoje em dia, a tecnologia faz parte integrante de vários aspectos da vida e da sociedade, impulsionando o crescimento económico e a mudança social, ao mesmo tempo que suscita preocupações sobre a segurança, a privacidade e os impactos ambientais. Espera-se que o futuro da tecnologia traga ainda mais avanços, prevendo-se que o aumento da inteligência artificial tenha implicações significativas no mercado de trabalho.

Localização de telemóveis is a process for identifying the location of a mobile phone, whether stationary or moving. Localization may be affected by a number of technologies, such as the multilateration of radio signals between (several) cell towers do network and the phone or by simply using GNSS. To locate a mobile phone using multilateration of mobile radio signals, the phone must emit at least the idle signal to contact nearby antenna towers and does not require an active call. The Global System for Mobile Communications (GSM) is based on the phone's signal strength to nearby antenna masts.

Mobile positioning may be used for location-based services that disclose the actual coordinates of a mobile phone. Telecommunication companies use this to approximate the location of a mobile phone, and thereby also its user.
