Question
When surveying an existing WLAN infrastructure for a possible redesign, you use two Wi-Fi USB adapters to collect RSSI data and two USB spectrum analysis adapters to collect RF spectrum data. Since your laptop doesn't have enough USB ports, you use a 4-port powered USB 3.0 hub. What issues could be caused by the use of USB 3.0 that will impact your site survey?
Options
- AIt does not give you enough bandwidth to collect data coming from all of the adapters.
- BIt does not give you enough power for all four of your adapters.
- CIt generates noise in the 2.4 GHz band, giving you a false perception of the noise floor.
- DIt generates noise in the 5 GHz band, giving you a false perception of the noise floor.
