100-150 Question 119
Single answerA company is troubleshooting poor wireless performance in their office. They primarily use 2.4GHz Wi-Fi for connectivity. Upon investigation, they find that their office is located near a factory using industrial microwaves and several Bluetooth-enabled devices. What is the most likely source of interference affecting their network?
- A
Industrial microwaves and Bluetooth devices
- B
Nearby 5GHz Wi-Fi networks
- C
Cellular tower signals
- D
6GHz Wi-Fi devices in the vicinity
Show answer and explanation
Correct answer: A
Explanation
The 2.4GHz band is shared by many devices, including industrial microwaves and Bluetooth devices, which can cause interference for Wi-Fi networks operating in this band. Understanding sources of interference is critical for troubleshooting wireless performance issues in networking environments.
- A. Correct.
Industrial microwaves and Bluetooth devices both operate in the 2.4GHz frequency band and are common sources of interference for 2.4GHz Wi-Fi networks.
- B. Incorrect.
5GHz Wi-Fi networks do not overlap with 2.4GHz signals, so they are unlikely to interfere in this scenario.
- C. Incorrect.
Cellular tower signals operate in licensed spectrum bands that are separate from the 2.4GHz frequency used by Wi-Fi, making interference unlikely.
- D. Incorrect.
6GHz Wi-Fi devices operate in a different frequency range than 2.4GHz Wi-Fi, so they would not cause interference in this case.
