WiFi Network Scanner and Analyzer

A Python-based tool for scanning, analyzing, and visualizing WiFi networks in your vicinity. This tool provides insights into network signal strengths and channel distributions through intuitive visualizations.

Features

• 🔍 Scans for nearby WiFi networks
• 📊 Creates heatmap visualizations of network signal strengths
• 📈 Generates CSV reports with network data
• 🖥️ Cross-platform support (Windows/Linux/MacOS)
• 🕒 Timestamp tracking for each scan
• 📱 Simple command-line interface

Requirements

• Python 3.x
• Required Python packages:
  • pandas
  • matplotlib
  • seaborn
  • numpy

Installation

1. Clone this repository

2. Install required packages:

pip install pandas matplotlib seaborn numpy

Usage

Run the script from command line:

python wifi_scanner.py

The script will:

1. Scan for nearby WiFi networks
2. Save network data to a CSV file
3. Generate a heatmap visualization
4. Save the visualization as a PNG file

Output Files

The tool generates two types of output files:

• wifi_data_[timestamp].csv: Raw network data
• wifi_heatmap_[timestamp].png: Visual representation of network signals

Sample Output

The heatmap visualization shows:

• X-axis: WiFi channels
• Y-axis: Network SSIDs
• Color intensity: Signal strength (%)

The CSV file includes:

• SSID (network name)
• Signal strength (%)
• Channel
• Timestamp

Permissions

• Windows: Run as administrator
• Linux/MacOS: Run with sudo privileges

Technical Details

The tool uses:

• netsh command on Windows
• iwlist command on Linux/MacOS
• Signal strength is measured in percentage (0-100%)
• Channel information for both 2.4GHz and 5GHz bands

Limitations

• Requires administrative privileges/location services
• Some network information might be hidden by the operating system
• Signal strength conversion might vary between operating systems
