The most obvious factor when choosing an oscilliscope is bandwidth. 50MHz is better than 20MHz, and 100MHz is definitely better than 50MHz, etc., but what does that number really mean, and how fast is fast enough for your needs? They're both capturing the 3.3V 40MHz pixel clock of a large (800×480) TFT LCD, and the frequency is the same
There are only 5 10Mhz non-overlapping channels in the 4.9Ghz spectrum, 2 20Mhz and 1 40Mhz channel. You have to pick between 5, 10, 20, or 40Mhz with MIMO. Although a lot of math could get involved, anytime you cut the bandwidth in half you lose half your throughput. Technically the larger the channel the more efficient it becomes, but it is
40Mhz will give you higher bandwidth/performance but will overlap other channels so if you have many outside wifi networks visible in your area 20Mhz would be best. 0 Kudos Reply
40 MHz Channel Width: Increased Throughput. The 40 MHz channel width doubles the available bandwidth compared to the 20 MHz channel width. This wider channel allows for higher data transfer rates, making it suitable for applications that require increased throughput.
For example, 802.11n Wi-Fi transmits in 20 MHz and 40 MHz channels within the 2.4 GHz and 5 GHz bands. Any one of more than 30 combinations of channel bandwidth (20, 40 MHz), modulation scheme ii. 40 MHz. 40 MHz is the most balanced channel width because it offers more throughput than 20 MHz without facing too much interference, as is the case with 80 MHz. 40 MHz is also best utilized in a 5 GHz frequency band because of fewer overlapping channels - 24 out of 45 don't overlap.

Config your capture device with the appropriate iw command. Validate that you are seeing traffic you expect, like QoS Data, etc, from the client. The radiotap header will tell you if it is 40MHz or 20MHz bandwidth. If it doesn't work, keep trying: change iw commands, move channels, get a different capture device, etc.

At the same time, Keenetic routers in the 2.4 GHz band with two spatial MIMO 2x2 streams and a channel width of 40 MHz can link up to 300 Mbit/s and actual speed (under ideal conditions) up to 120 Mbit/s. It is impossible to fix the 40 MHz channel width mode in the router, as this is a recommendation of the standard.
20MHz dan 40MHz adalah satuan ukuran frekuensi yang digunakan dalam teknologi jaringan wireless. Kedua ukuran ini adalah lebar saluran frekuensi yang digunakan untuk mentransmisikan informasi antara router atau access point dan perangkat komputer atau smartphone. .
