Guys you can view my previous speed tests on 20MHz bandwidth here:-1) https://youtu.be/NfJIW_UQkKU
The channel widths vary depending on the WiFi standard. For example, in the (wireless networking standards) 802.11n and 802.11ac, the standard channel widths are 20, 40, 80, and 160 MHz. 40 MHz can carry twice as much data as 20 MHz while being more susceptible to interference. 80 MHz can have twice as 40 MHz, and so on.
WiFi 20 MHz atau 40 MHz: bagaimana memilih bandwidth. Beli a router Wi-Fi baru kita akan sering menemukan kata-kata « 300 Mbps «, Kecepatan yang diperoleh dengan koneksi WiFi pada frekuensi 2,4 GHz.
20MHz memiliki bandwidth 20MHz, sedangkan 40MHz memiliki bandwidth 40MHz. Dengan kata lain, 40MHz memiliki dua kali lipat bandwidth dibandingkan dengan 20MHz. Perbedaan Kecepatan. Perbedaan utama antara 20MHz dan 40MHz adalah kecepatan.
By default, the 2.4 GHz frequency uses a 20 MHz channel width. A 20MHz channel width is wide enough to span one channel. A 40 MHz channel width bonds two 20 MHz channels together, forming a 40 MHz channel width; therefore, it allows for greater speed and faster transfer rates.
