Figure 18: Selection of 5G 20MHz primary channel
11. Recommended 5G channel bandwidth selection in different scenarios:
❖ 20MHz channel bandwidth: high-density areas, such as large stadiums, large event
gatherings, urban hotspots where many WLAN networks are deployed;
❖ 40MHz channel bandwidth: normal-density area, such as large building office area;
❖ 80MHz channel bandwidth: low-density areas, such as small building areas, and areas with
less WLAN deployment;
❖ 160MHz channel bandwidth: single AP area with small coverage, such as at home.
