Introduction ​

This document details the functionality of analysis of nearby Wi-Fi networks, an essential tool to optimize wireless network performance and coverage. This function allows you to view and analyze all nearby Wi-Fi networks, providing crucial information about channels, interferences and network density.

Access to Functionality

Path: Devices Menu -> Select Equipment -> Diagnostics tab -> Next Networks option

Overview of Functionality ​

Close networks refer to networks that are physically close to each other or share a common infrastructure. When starting the next network test, the system performs a complete Wi-Fi scan, collecting data on:

  • Wi-Fi networks detected in the 2.4GHz and 5.8GHz bands
  • Channels used by each network
  • What? Interference levels in each channel
  • What? Number of networks operating on each channel

Components of Analysis ​

1. Signal Network Chart ​

This visual graph represents:

  • Distribution of detected networks
  • What? Signal intensity of each network
  • What? Easy comparison between different networks in the area
  • Interpretation:*
  • X-axis: Generally represents channels or frequencies
  • Y-axis: Indicates signal intensity (usually in dBm)
  • What? Each point or line represents an individual network

2. Signal Interference Index Chart ​

This graph shows:

  • What? Interference levels in different channels
  • Relationship between interference and signal intensity
  • Interpretation:*
  • Areas with high interference indicate jammed channels
  • Ideal to seek channels with less interference for better performance

3. List of Networks Found ​

A detailed table with information on each network detected, including:

  • Network name (SSID)
  • Channel used
  • What? Signal intensity
  • Security type (WPA2, WPA3, etc.)
  • Device manufacturer (if available)

Practical Use ​

Channel Optimization

  1. Identify less congested channels
  2. Adjust your router channel to minimize interference Coverage Planning
  3. Analyze the distribution of existing networks
  4. Plan the placement of new access points for better coverage Diagnosis of Problems
  5. Identify possible sources of interference
  6. Correlate performance problems with channel congestion

Best Practices ​

  1. Perform analyses at different times of the day
  2. Compare results between 2.4GHz and 5.8GHz for informed decisions
  3. Consider switching to less used channels
  4. In dense environments, prioritize the use of the 5.8GHz band when possible

Security considerations ​

  • What? Analysis can reveal private networks; use information ethically
  • Avoid connecting to unknown networks detected during analysis

Common Troubleshooting ​

  • Many networks on the same channel: Consider switching to a less congested channel
  • Weak signal in certain areas: Evaluate the need for additional repeaters or access points
  • Consistent interference: Investigate non-Wi-Fi interference sources (e.g. microwave ovens, Bluetooth devices)

Final considerations ​

The analysis of nearby Wi-Fi networks is a powerful tool to optimize the performance of your wireless network. Use it regularly to keep your network operating in optimal conditions, especially in environments with many competing networks.
