Thisis where we can start taking advantage of wider channels without too many drawbacks. The 5 GHz frequency brings 24 non-overlapping 20 MHz channels. That's more than 6 times the bandwidth of 2.4 GHz. This means we could bond two adjacent 20 MHz channels together, and have twelve 40 MHz channels. All without interference from our own devices.
The5 GHz band has a wider wireless spectrum available compared to the 2.4 GHz band, which leads to significantly better performance as the 5 GHz band is commonly used for usage that requires uninterrupted throughput. That is why it is recommended for media streaming and transferring music, pictures, and video throughout your home network.BW: 40MHz. มีความเร็วสูงกว่าเท่าตัว (150Mbps@1 Spatial Stream/300Mbps@2 Spatial Stream) ใช้แถบความถี่มากกว่าเท่าตัว ทำให้มีการถูกรบกวนสูงกว่าเท่าตัว. มีความไว
UsingAsuswrt-Merlin 376.48.1 on RT-AC68P. On the 5GHz wireless configuration options, the bandwidth can be set to 20MHz, 40MHz, 80MHz or what appears to be an auto setting of 20/40/80 MHz. Is 20/40/80 an auto setting? Is there an advantage or penalty for using 80 or 20/40/80?
Whenthe OFDM PHY was introduced to 802.11, the channel bandwidth was 20MHz with later amendments adding support for 5 and 10MHz bandwidths. The 802.11n amendment added support for an optional 40MHz channel. 802.11ac will include support for 80MHz bandwidth as well as an optional 160MHz bandwidth. The 11acAccordingto the WiFi 802.11b/g/n standard, channel widths of 20MHz or 40MHz can be configured in 2.4GHz WiFi networks. For simplicity, 20MHz channels have been represented, but the same situation occurs with 40MHz channels, occupying in this case twice the width. This is the reason why it is said that the best channels are 1, 6 and 11. Having k7qNaJ.
