基于 Wi‑Fi 信号的室内定位与干扰排查
问题概述
当前缺乏高精度、可定制且尊重用户隐私的无线信号定位工具；现有 API 提供的坐标过粗，且许多平台通过固定标识追踪用户位置，用户希望能够自行测量并排除干扰。
痛点标签
- 定位精度不足（坐标过粗）
- 隐私泄露风险（追踪担忧）
- 缺乏自定义 SSID 以退出追踪的机制（需要 _nomap）
- 对 Wi‑Fi 信号干扰的排查需求
待验证问题
- 您是否愿意为此类定位/干扰排查工具付费？
- 您是否经常遇到 Wi‑Fi 信号干扰或定位不准的问题？
- 您会如何改进现有定位 API 的精度或隐私保护？

I started rotating my BSSID weekly after I learned Apple and Google abused it to track the location of people and devices.Permanent hardware or software IDs, such as the Windows GUID or machine-id on Linux (systemd) are inevitably abused for surveillance sooner or later.

Worth noting that the coordinates for cell towers returned by the WLOC API are coarse enough to be just about useless for locating towers. For APs it’s much better but still not great.

Looks like an open version of SkyHook from way back in 2003: https://en.wikipedia.org/wiki/Skyhook_WirelessFor a while they had a paid program, I had a Windows Mobile app I could run with an external GPS dongle that would record wifi APs and location, upload to skyhook, who would occasionally cut me a check for my trouble. I made tens of dollars!

Apple says you can opt out of this collection by appending _nomap to the SSID:https://support.apple.com/en-us/102515> The owner of a Wi-Fi access point can opt it out of Apple's Location Services by changing the access point's SSID (name) to end with "_nomap." For example, "Access_Point" would be changed to "Access_Point_nomap."
