2023年12月7日 · 本文介绍了WiFi协议名称的变迁,从技术专业术语变为易懂的版本(如802.11n变Wi-Fi4),并展示了各代WiFi的理论速率提升,如Wi-Fi6单流达到1200Mbps,标志着WiFi技术的快速发展。
List of WLAN channels - Wikipedia
The 802.11 standard provides several radio frequency bands for use in Wi-Fi communications, each divided into a multitude of channels numbered at 5 MHz spacing (except in the 45/60 GHz band, where they are 0.54/1.08/2.16 GHz apart) between the centre frequency of the channel.
Understanding 2.4 GHz, 5 GHz, and 6 GHz Wi-Fi Frequencies
2024年10月3日 · Each Wi-Fi frequency comes with its own set of strengths and weaknesses. The 2.4 GHz band has been around the longest, offering broader range but slower speeds, while 5 GHz is faster but more limited in coverage.
