The discussion began with a question asked by Hacker News user t8sr, “Why is a Bluetooth connection less reliable than other wireless standards like Wi-Fi?'' t8sr claims that “Bluetooth connections are unreliable regardless of hardware, operating system, system, or purpose Specific examples include: “The connection is unstable even between devices from the same manufacturer'' “When listening to music using headphones or earbuds connected via Bluetooth, the music may interrupt as soon as you move your body.'' “Bluetooth connection On Windows machines it gives examples like “It's not working”.

Mr. t8sr's question received many answers. It attracts attention amongAnswerAccording to zh3, “Bluetooth connects using the same 2.4GHz band as Wi-Fi. Wi-Fi has an output of 100 mW, while the output of many Bluetooth devices is 1 mW. For this reason, Bluetooth communication uses the same 2.4 GHz band as Wi-Fi and is vulnerable to interference with Wi-Fi connections. Bluetooth technology is divided into three classes depending on the radio field strength, Class 1 can output up to 100 mW, Class 2 can output up to 2.5 mW, and Class 3 can output up to 1 mW. 2.4GHz Wi-Fi, on the other hand, outputs at 100mW, so zh3 claims Class 2 and Class 3 Bluetooth devices are hidden behind the Wi-Fi connection.

On the other hand, lxgr responded to zh3's opinion by saying: “Bluetooth continues to transfer data without regard to other connections, but Wi-Fi may drop the connection depending on the exclusive status of the channel.” He noted that just because Bluetooth uses the same frequency band as Wi-Fi, that doesn't mean it will always receive interference from Wi-Fi.refuteWork.In addition, lxgr said: “AirPods are top-tier Bluetooth devices and can connect at speeds of up to 100mW.”advertiserclaims that depending on the device, it is possible to connect to a similar strength to Wi-Fi.

Additionally, the page states that “Depending on the device, Bluetooth Audio plays music immediately upon successful connection,” while others do not play music unless the play button is pressed even after successful connection, which is confusing.opinion“When your laptop is connected to Bose headphones, a voice message saying 'Connected to your laptop' will play once every 30 seconds.''a reportIt was also well received, highlighting the fact that many people are not satisfied with Bluetooth connectivity.
