Next Networks
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.

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
- Identify less congested channels
- Adjust your router channel to minimize interference Coverage Planning
- Analyze the distribution of existing networks
- Plan the placement of new access points for better coverage Diagnosis of Problems
- Identify possible sources of interference
- Correlate performance problems with channel congestion
Best Practices
- Perform analyses at different times of the day
- Compare results between 2.4GHz and 5.8GHz for informed decisions
- Consider switching to less used channels
- 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.
