WIFI speakers are so convenient, why now the mainstream or Bluetooth speakers?

baby99331166 answer is very detailed, and even very professional, very comprehensive, so professional so detailed, so comprehensive I would not dare to say to add, then we will be in the professional level to simply explore it. First of all, Bluetooth and WiFi in a long time are in *** with the use of 2.4g band, until recently these two years WiFi only began to use 5.8g band, then WiFi in the transmission line bandwidth is indeed higher than the loan of Bluetooth. But then, he has constraints on its own WiFi coverage of the fixed, Bluetooth is able to follow the Bluetooth lock supporting equipment, such as cell phones, tablets, etc., can realize the outdoor use of the scene, WiFi it can only be in. Home or WiFi specific environment can only be used, so the Bluetooth speaker in portability is indeed a little more expansive. In terms of sound quality performance, due to the higher bandwidth of WiFi, WiFi's transmission capacity is relatively stronger, it seems that the sound quality performance is better than that of Bluetooth, in fact, it is the same, why is it the same, because please. Note that most or the vast majority of the song content of today's major online platforms are in mp3 format, and the compression ratio is almost always at the same level, such as the 320k sampling rate. Almost most of the music playback platform adopts a standard, of course, there are some compression is more powerful, the effect of online listening is not so ideal, so that in the compression ratio, whether WiFi or Bluetooth, are able to transmit well close to countless. Lossy sound quality of music, so in fact, in addition to wc and other ultra-high-quality compression ratio of music, almost bluetooth and WiFi music transmission, the bandwidth listing can be satisfied. In addition, today's bluetooth version is getting higher and higher, bluetooth intelligence as well as bluetooth functionality is getting stronger and stronger, for example, today's bluetooth, almost high-end product line, or the big brands used are dual-mode bluetooth with ble technology. ble technology, is that it can be in a very small power consumption under the transmission of the long distance. That is to say, today's Bluetooth products can realize two interconnections or multiple interconnections, and not lose to WiFi in the application scenarios.
