Radiobased

Radiobased is a term used to describe systems and processes that rely on radio frequency signals to transmit information, sense the environment, or enable control and positioning. It encompasses technologies that operate without a physical medium other than the air, and includes both private networks and publicly accessible services.

The scope of radiobased technologies includes radio-based communications (cellular networks, Wi‑Fi, Bluetooth, NFC, LoRa, Sigfox), radio-based localization and tracking (RFID, beacons, other location systems), and radio-based sensing and radar for detection, imaging, and safety applications. It also covers sensing methods that use ambient radio emissions to infer properties of objects or environments, such as passive radar or radio tomography.

Core components involve RF transceivers, antennas, spectrum allocation, and signaling protocols. Performance depends on bandwidth, modulation schemes, coding, multiple access methods, and interference management. Security and privacy rely on encryption, authentication, and access control, while reliability requires robust link budgets and error handling.

Applications of radiobased technologies span telecommunications, Internet of Things, asset tracking, navigation, automotive and unmanned aerial vehicle sensing, industrial automation, healthcare monitoring, and smart cities. In research and development, radiobased approaches are studied for resilience, energy efficiency, and integration with other sensing modalities such as optical or acoustic systems.

Challenges include spectrum regulation, interference from dense deployments, environmental variability, security threats, and privacy concerns. Advancements focus on next-generation networks (such as 5G and beyond), ultra-wideband approaches, cognitive radio, and cooperative sensing to improve range, reliability, and accuracy while managing spectrum efficiently.
