Figure 9: Control cellular size of the AP by lowering the transmission power
In this scenario, the access point has the connection rate below 24 Mbps closed. (18 Mbps and 24 Mbps
are relatively stable connection rates. Please do not close it in real deployment.) By standing at the
position of -80dbm, the probability of beacon being detected is reduced by a lot. So, it reduces the range
indirectly. However, this feature will affect the client connection from the coverage edge and is only
suitable for high-density AP deployment scenarios.
5. Planning of channel multiplexing
Efficient channel planning, by avoiding the co-channel and adjacent channel interference, can greatly
reduce the channel utilization of the working channel (see the section on co-frequency interference and
adjacent-frequency interference mentioned above).
6. Eliminate illegal devices or non-Wi-Fi devices in the same spectrum
Non-WiFi Interference is hard to eliminate during wireless network planning and designing, and it is also
difficult to find, usually by capturing packets or spectrum scanning.
In real situation, you can first test in a near-end and then far-end for a throughput value. In the case of low
throughput or abnormal fluctuations, make a comprehensive judgment of the integrated SNR and
Channel Utilization data, and run wireless capture, if necessary, to confirm.
