What are the channel width options for 5GHz wifi?

  1. 10 cm and 20 cm

  2. 20 MHz and 40 MHz

  3. 424 Kbps

  4. 75W

The correct answer is: 20 MHz and 40 MHz

The channel width options for 5GHz wifi are typically measured in MHz (Megahertz). Option A and D are not accurate as they refer to measurements of width in centimeters and power in watts respectively. Option C is also incorrect as it refers to the data rate of the wifi signal and not the channel width. Therefore, option B, which lists the 20 MHz and 40 MHz channel width options, is the correct answer. These are the standard channel width options for 5GHz wifi networks.
