The BSA of an AP covers the area used by the sales and marketing department. Thirty-five stations operate in this space. The users indicate that they need more throughput and all stations are 5 GHz…

Question

Options

• AUse a 160 MHz channel on the 5 GHz radio
• BUse a 40 MHz channel on the 5 GHz radio
• CInstall a second AP in the coverage area
• DUse a 40 MHz channel on the 2.4 GHz radio

• A
  12% (5)
• B
  49% (20)
• C
  7% (3)
• D
  32% (13)

Explanation

The least expensive solution available for increasing throughput for these users without implementing configuration options that are not recommended is to use a 40 MHz channel on the 5 GHz radio. This solution can double the channel bandwidth and increase the data rates for the 5 GHz capable 802.11ac clients. Using a 40 MHz channel on the 5 GHz radio is also less likely to cause co- channel interference or overlap with other channels than using a 40 MHz channel on the 2.4 GHz radio, which has only three non-overlapping channels. Using a 160 MHz channel on the 5 GHz radio may provide even higher throughput, but it may also consume too much of the available spectrum and cause more interference with other devices or networks. Installing a second AP in the coverage area may also improve the throughput, but it may require additional costs and configuration.
