Question
When conducting a site survey for a possible WLAN redesign, you use two Wi-Fi USB adapters for RSSI data collection and two USB spectrum analysis adapters for RF spectrum data. Since your laptop lacks enough USB ports, you connect them via a 4-port powered USB 3.0 hub. What issue could the use of USB 3.0 cause that might impact your site survey?
Options
- AIt does not give you enough bandwidth to collect data coming from all of the adapters
- BNo USB 3.0 hub provides enough power for all the 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
