Cell tower near

A decision block that checks nearby cellular towers.

If the proceed option is set to Immediately, then check if any of the cell towers is currently nearby without pausing the fiber. If set to When changed, then the fiber will pause until the device comes near any of the cell towers, or until none of the towers is nearby.

If no cell towers are supplied, the nearby cell towers are collected/scanned and assigned to the nearby cell towers variable without a (intersection) check, proceeding through the YES path.

The cell towers input argument can be a single cell, a text of comma separated cells, an array of single cells or a dictionary where each key is a single cell.

The arrays assigned to Nearby cell towers and Signal strengths are of equal length, sorted in signal strength order.

Cell format

A cell is text that begins with a network type followed by one or more optional hexadecimal properties separated by colon:


Note! Finding nearby cells will be slow for devices (Samsung) that doesn’t report neighboring, unconnected, cell towers. Some devices only report cells when the screen is lit, use the Device keep awake block to keep the screen on continuously, or at regular intervals.

Note! Android 6 will only report nearby cell towers when the system Location setting is enabled.


  • Proceed — when the fiber should proceed.

Input arguments

  • Cell towerscells to check if they’re nearby or not.

Output variables

  • Nearby cell towers — variable to assign an array of nearby cells.
  • Signal strengths — variable to assign an array of signal strengths, in dBm.
Note! This documentation can also be found in the Help & feedback menu of the app.
