What additional devices commonly use the 2.4 GHz band, causing potential interference?

The 2.4 GHz band is commonly used by various wireless technologies, making it susceptible to interference from devices that operate on the same frequency. Bluetooth devices are a prime example, as they utilize the 2.4 GHz spectrum for short-range wireless communication. This overlap can lead to interference with Wi-Fi signals, affecting performance and connectivity.

Bluetooth operates on a frequency-hopping spread spectrum, which helps minimize interference by rapidly changing frequencies during transmission. However, the shared frequency band means that when many Bluetooth devices are in use, they can still disrupt Wi-Fi connections, particularly in crowded environments with several competing signals.

Other options, such as mobile phones, typically use different frequency bands for their cellular connections and would not cause significant interference with a Wi-Fi network. Fiber optic cables rely on light transmissions and do not operate in the radio frequency spectrum, thus having no impact on the Wi-Fi signals. Satellite communications also primarily function in different frequency ranges and do not contribute to interference with the 2.4 GHz band. Therefore, Bluetooth devices are the most relevant example of common devices that can cause interference with Wi-Fi operating on the same frequency.
