Why Bluetooth 4 devices won't interfere with your Wi-Fi?

The following points illustrate why Bluetooth 4 devices will not interfere with your WiFi:

1. Frequency: Bluetooth and WiFi operate on different frequencies. Bluetooth uses 2.4 GHz, while WiFi can use 2.4 GHz or 5 GHz. Therefore, they operate in different frequency ranges and are unlikely to interfere with each other.

2. Power: While WiFi devices are more powerful than Bluetooth devices, the transmission power of a Bluetooth device in advertising mode at 0db is relatively low. This means that the Bluetooth signal is not strong enough to interfere with the WiFi signal.

3. Protocol: Bluetooth and WiFi use different communication protocols, which means they have different methods of transmitting data. This reduces the likelihood of interference between the two technologies.

4. Standards: Both Bluetooth and WiFi have specific standards that must be met to ensure that they do not interfere with each other. These standards dictate things like the frequency range, transmission power, and modulation techniques used by the devices.

Overall, it is important to emphasize that Bluetooth and Wi-Fi are designed to coexist without interfering with each other. The likelihood of interference is low, and there are standards in place to ensure that both technologies work together seamlessly.
