In a densely populated urban area, you're responsible for troubleshooting connectivity issues in a public Wi-Fi network. How would you identify and mitigate potential sources of interference?

  • Analyze nearby networks, use Wi-Fi scanners, employ frequency hopping, use directional antennas
  • Analyze signal-to-noise ratio (SNR), implement airtime fairness, use MIMO technology, configure Wi-Fi scheduling
  • Use signal attenuators, implement congestion control algorithms, employ frequency division multiplexing (FDM), use Wi-Fi extenders
  • Utilize Wi-Fi heatmaps, implement band steering, use channel bonding, configure transmit power levels
In a densely populated urban area, identifying and mitigating interference in a public Wi-Fi network requires analyzing nearby networks to understand their frequencies and signal strengths. Wi-Fi scanners can provide detailed information about neighboring networks, helping in choosing less congested channels or frequencies. Frequency hopping can be used to avoid interference by switching between different channels rapidly. Directional antennas focus signals in specific directions, reducing interference from unwanted sources. These methods help identify and address interference issues effectively.
