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
It's just bandwidth - how much data can be carried at once. Think about a cargo van and a semi truck both going the same speed down the highway. You generally want to go with 40 MHz channels for client serving in most cases. Wider channels generally work best for wireless bridge applications in areas with very few potential interfering
it divides the 80 mhz bandwidth into 20 mhz chunks and center the client on one of those chunks. Same goes for if you can only do 40mhz, it does 2 chunks and centers on one of those chunks. This means there is never any overlap or interference.When the bandplan was created this was the point of grouping it the way it is. 1 80 mhz channel, = 2
Ngoài ra, bạn có thể chọn 40Mhz sóng 2.4Ghz ở bất kỳ kênh tần trong số 1, 6, 3 và 11 khi nó ít bị nhiễu sóng nhất.

Lưu ý: Việc lựa chọn băng thông Bandwidth denotes the range of your broadcasting channel. 20 MHz is considered "standard" bandwidth, but 40 MHz is twice the channel width. Many people propose 40MHz mode in 2.4GHz only for individuals who reside in remote areas. In 40MHz mode, your WiFi uses 2/3 of the entire 2.4GHz band, and you compete for air time with your neighbors' WiFi. Q3oD2Dh.
