Webb8 okt. 2024 · If the bandwidth (which can be configured) is 22 MHz, then the modulated signal on channel 6 will be in range from (2437 MHz - 11 MHz) to (2437 MHz + 11 MHz), i.e. from 2426 MHz to 2448 MHz. As you can see, the range from 2426 MHz to 2448 MHz overlaps with other channels, and this is absolutely legal in Wi-Fi (unlike GSM). Webb20 feb. 2015 · Yes of course MIMO breaks the shannon's bound.
