Guys you can view my previous speed tests on 20MHz bandwidth here:-1) https://youtu.be/NfJIW_UQkKU
When you're making a decision between 20 MHz vs 40 MHz vs 80 MHz vs 160 MHz what you're doing is picking a channel width. We got an introduction to Wi-Fi channels above. We saw that the 2.4 GHz Wi-Fi band is chopped up into smaller 20 MHz bands for use. These smaller bands are the channels that Wi-Fi devices communicate on.
Difference between 20Mhz and 40Mhz . The difference between 20Mhz and 40Mhz can be imagined as the width of the road. The wider the width, the more data can be run at the same time, which increases the speed.
Networking. Frequency Bandwidth: 20MHz vs 40 MHz vs Auto. We have two wireless AP's in the house, one is from the ISP provided router and one is a WiFi repeater. Our area isn't congested, though there are times when two of my neighbors' AP's pop up randomly.
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.
Channel Bandwidth: 20MHz, 40MHz (40MHz optional) 20MHz, 40MHz, 80MHz, 80+80MHz & 160MHz (40MHz support made mandatory) 20MHz/40MHz @ 2.4GHz, 80MHz, 80+80MHz & 160MHz @ 5GHz. Subcarrier Spacing
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.
