QuestionQ1

Fondamentaux du Wi-Fi

Which two statements are true regarding channel bonding?

Choose two
  • A Bonding two channels together doubles the available bandwidth.
  • B Bonding two channels together doubles the required device resources.
  • C Bonding two channels together doubles the noise floor.
  • D Bonding two channels together doubles the number of available channels.
Explanation

Combining two equal-width channels produces twice the channel bandwidth and therefore twice the theoretical capacity. Because integrated thermal noise is proportional to bandwidth, doubling the channel width doubles noise power, which is a 3 dB increase in the noise floor. Cisco notes that wider channels increase the noise floor and reduce SNR by 3 dB for each doubling of channel width.
