# MXUnitSignalBars

A unit of measure for the number of bars of cellular network connectivity.

## Declaration

```swift
class MXUnitSignalBars
```

## Overview

Overview Cellular connectivity measures the relative strength of the device’s signal reception in decibels, which usually falls in a range of 0 to -110. MXUnitSignalBars defines the base unit as bars corresponding to the bars in the cellular connection status icon at the top of a device screen.
