Understanding Wi-Fi bands is vital to understanding when to use 20 MHz versus 40 MHz versus 80 MHz channel widths. It's also an important prerequisite to understanding WiFi channels and channel width. The two main Wi-Fi bands are 2.4 GHz and 5 GHz. These Wi-Fi bands are then split into channels for wireless devices to communicate on.

What users do not know is that to obtain this speed it is necessary to act on the router and configure the Band Width item (in some routers also called Band Width, WiFi Bands or WiFi 20 MHz or 40 MHz).
Perbedaan Bandwidth 20MHz dan 40MHz Pada Setting Router Wifi By Pramana - 23 January 2017 64971 Channel width adalah lebar saluran 20Mhz atau 40Mhz, dan 80Mhz yang pada dasarnya sangat penting untuk mengontrol seberapa luas sinyal untuk mentransfer data.
Back than there wasnt much 2.4Ghz traffic so the higher bandwidth helped. In a densed wifi environment 20 mhz helps more than 40mhz. It is possible to apply 40mhz on channels 1 or 13 which will give less of a chance of interference. back than wifi practical rates were a lot lower than now.
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.

With 20MHz-wide channels on 802.11n, you can only get the 72.2, 144.4, or 216.6Mbps top PHY rates (for 1-, 2-, and 3 spatial streams, respectively). Going to 40MHz-wide channels makes it 150, 300, and 450 Mbps, respectively.

There are only 13 20MHz channels in 2.4GHz, which quickly become congested due to many devices that, in turn, generate interferences. Thus, it's practically impossible to connect to 40MHz channels in that frequency band.
