About WikiBeacon.org

Wikibeacon.org is a community resource providing crowd-sourced information about proximity beacon usage.

Data Sources

The data is crowdsourced from the Locate app for iOS and Locate app for Androidâ„¢. This directory is not a comprehensive list of beacons around the world, but those detected by the tens of thousands of users of the Locate apps. For more information on how to contribute to WikiBeacon or to get a beacon added to the directory, take a look at our how to expand WikiBeacon page. Some beacon information reported to this database has been removed at owner request. These beacons are included in aggregate counts but are not shown on the map and detailed records are not visible.

Location Data

Reverse geocoding is performed for each beacon using openstreetmap.org based on the latitude and longitude of the beacon. The reported locations rely on the phone or other mobile device's known location at the time the beacon is detected. The location may come from GPS data, WiFi networks or cell towers depending on the positioning capabilities of the mobile device.

Multiple Location Reports

When multiple reports are issued for the same beacon (as identified by the unique UUID/major/minor combination) then the average position of the most recent 100 reports is used. In cases where there is no consensus for the location of a beacon, a position is not provided by the system. A consensus is defined as 80 percent of reports showing a beacon within about two kilometers. Lack of consensus explains why many beacons with common test identifiers (e.g. Apple AirLocate's UUID: E2C56DB5-DFFB-48D2-B060-D0F5A71096E0, Major: 1, Minor: 1) do not have an associated location.

Location Accuracy

Keep in mind that mobile location data is inexact so beacon locations may be off by up to 50 meters if GPS is the source of the location, by 200 meters if WiFi is the source of the location, or even several thousand meters if a cell tower was the source of the location.

Map Icon Colors

Map color coding of beacons is based on the first detection time and reflects how recently the beacons have been added to the site. Yellow icons represent beacons added in the past day. Orange within the past 3 days, purple within the last seven days, blue within the last 30 days and green more than 30 days ago. In cases where multiple beacons are in the same location, the icon shows as red with numbers on the icon indicating how many are in the location. Tapping on a red icon will zoom in to show you the individual beacons.

API Access

Currently, the website is the only way to access the data. Our first step was to collect data, the second step was to share the data, and providing an API to access the data will come in the future.

Privacy

Data collected by Wikibeacon.org through the Locate apps contain no personally identifiable information, app users must opt-in before sharing data, and may opt-out at any time. Radius Networks' full privacy policy may be viewed here.
