频段(Frequency Band):“不同的高速公路” 频段指的是无线电波的一个特定频率范围,这个范围被分配给无线通信使用。不同的无线通信技术会使用不同的频段,避免相互之间的干扰。 如最常见的Wi-Fi频段有两个:2.4GHz和5GHz。这两个频段就像是两条不同的高速公路,2.4GHz频段覆盖范围较广,穿透能力强,但可能较拥挤、易...

15.4.4.2 Operating frequency range The DSSS PHY shall operate in the frequency range of 2.4 GHz to 2.4835 GHz as allocated by regulatory bodies in the China, United States and Europe or in the 2.471 GHz to 2.497 GHz frequency band as allocated by regulatory authority in Japan 16.3.6.2 Operat...
Signal interference often comes from everyday household devices operating on the 2.4GHz frequency band, including microwave ovens, cordless phones, and baby monitors. Bluetooth devices and neighboring Wi-Fi networks can also compete for bandwidth, potentially degrading your network performance. Distance na...
If you device cannot detect the 5 GHz Wi-Fi signal, check the following items: 1. Check whether the device supports the 5 GHz Wi-Fi frequency band. On the product specifications page on the device brand's official site, check whether the device supports the 5 GHz Wi-Fi. You can also...

Frequency band: 802.11n: Typically operates in two bands, 2.4 GHz and 5 GHz, but performs poorly in the 2.4 GHz band because it suffers from interference and congestion. 802.11ac: Mainly works in the 5 GHz band, which is relatively less crowded and provides higher performance and speed. ...
“spread spectrum” technique in which a signal is broken into pieces and transmitted over multiple frequencies. Spread spectrum enables the signal to be transmitted at a lower power per frequency and also allows multiple devices to use the same Wi-Fi transmitter. Because Wi-Fi signals are often...
Wi-Fi devices had previously been restricted to using only the 2.4GHz and 5GHz frequencies, but that’s recently changed. Wi-Fi 6E enabled devices can utilize the 6GHz frequency band, which provides 1,200MHz of bandwidth, making it ideal for delivering high amounts of data shorter distances...
If a speaker is Wi-Fi compatible, we check its Wi-Fi version and which frequency band it uses. We also check whether a speaker has Apple AirPlay and Google Chromecast built-in. If it does, we test its latency over each connection, which indicates how suitable it is for watching videos...
