Explain how the PCIe antenna functions with Bluetooth.
The PCIe module typically contains both WiFi and Bluetooth chips, but they function differently—WiFi requires a USB link to the motherboard, while Bluetooth connects via PCIe. The Bluetooth chip doesn’t necessarily depend on the PCIe connection; it operates independently. Regarding antennas, their count remains consistent across models, whether WiFi-only or dual-band. For a two-antenna device, the Bluetooth module likely shares or uses the same antenna setup as the WiFi component. Characteristics can vary with higher-end products, but for budget options under 50€, the differences are usually minimal.
They have the opposite setup, using USB for the Bluetooth module and PCIe for the Wi-Fi module. Otherwise, the Wi-Fi would be restricted by the USB 2.0 speed, which is why they separate them this way. I’m not sure why this division is necessary or what the limits are. Not every card requires a USB connection for Bluetooth. The dual antennas are typically used for both 2.4Ghz and 5Ghz Wi-Fi, and since Bluetooth also works on 2.4Ghz, it shares the antenna with that type of Wi-Fi.
Thanks a lot for your support! Using the antenna definitely improves performance compared to those small USB Bluetooth adapters, which often have limited range.
