# LBS detection radius

Tunes cellular/Wi-Fi-based positioning, used as a fallback when GPS isn't available. It sets how far the Navixy platform trusts a base-station or Wi-Fi fix to pinpoint the device.

## Settings

* **Maximum radius**: The radius within which the platform trusts a cell-tower/Wi-Fi fix. Range 0–5000 m, set with a slider that offers locale-aware presets (for example 100, 500, 1000, 3000, or 5000 m in metric).

## Availability

Appears when the device supports LBS and the plan/account enables it, or for mobile app devices.

## Choosing a radius

* **Rural areas**: Use a larger radius. With fewer base stations, allowing more distant towers improves the chance of locating the device.
* **Urban areas**: Use a smaller radius. Dense towers provide enough signal for accuracy, so a smaller radius keeps precision higher.

## Limitations

* Larger radius = wider search but lower accuracy.
* On the map, LBS positions appear as a circle whose size equals the inaccuracy: a small circle means higher accuracy (typically urban), a large circle means more inaccuracy (typically rural).

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://navixy.com/docs/user/guide/devices-and-settings/location-and-movement/lbs-detection-radius.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
