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.
Guys you can view my previous speed tests on 20MHz bandwidth here:-1) https://youtu.be/NfJIW_UQkKU
In theory, 40Mhz has twice the channel bandwidth compared to 20Mhz, and the theoretical data transmission rate is also twice as high; However, from a practical application perspective, setting a higher bandwidth has a greater chance of conflicting with surrounding WiFi signals, which can affect the actual data transmission rate.
Assalamualaikum friends@LifeWithAamir In this video discuss about 2.4ghz wireless channel width, who's best in 20mhz or 40mhz ?@LifeWithAamir For more videos
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).
