Testing Your WIFI Connection

The Testing Your WIFI Connection process guides users in diagnosing wireless network stability on Android handheld devices using a third-party application. Its primary purpose is to help identify signal drops and channel congestion that may disrupt real-time communication with the server. This article is intended for OPS-COM administrators and field enforcement staff.

Setup and Configuration

To accurately test your network connection, you must install a specific third-party diagnostic application on your Android handheld device.

Admin Side: No backend administrative setup is required.

Open

Downloadthe Google Play Store on your Android handheld device.

Visual Cues & Status Indicators

• Signal Strength Graph: The signal strength is shownvisually represented as a  column of colourcolor rising up from the bottom of the graphgraph, thattypically rangesranging from minus-100 100dbdBm to minus-20 20db.dBm.

• Reading dBm Values: Signal strength is measured in negative numbers. The smaller the numbernegative number, the higher (stronger) the signalsignal. (keepKeep in mind that thesea numbersvalue arecloser negativeto sozero (e.g., -10020 isdBm) indicates a much better signal than a lower number (e.g., -20)100 dBm).
