Optimizing Wi-Fi 6E Channels for Office Densities

### Overview With the opening of the 6 GHz spectrum, Wi-Fi 6E provides massive bandwidth with zero legacy interference. However, improper channel planning in multi-AP office configurations can cause excessive cell overlap and roaming failures. --- ### Best Practice Rules #### 1. Channel Width Selection Avoid 160 MHz channel widths in dense corporate deployments. While they offer extreme peak speeds, they limit the number of non-overlapping channels. Use **80 MHz** or **40 MHz** channel widths to prevent co-channel interference. #### 2. Transmit Power (Tx) Tweaking Because the 6 GHz signal attenuates faster than 5 GHz or 2.4 GHz, administrators often set 6 GHz transmit power too high. This disrupts client roaming algorithms. Keep 6 GHz power levels approximately **3-4 dBm higher** than 5 GHz, while keeping 2.4 GHz power levels at a strict minimum (e.g. 6-8 dBm). #### 3. Channel Mapping Grid (80 MHz) In India, ensure your APs are locked to the following non-overlapping channel numbers in the U-NII-5 band: * **Channel 37** (5955-6035 MHz) * **Channel 53** (6035-6115 MHz) * **Channel 69** (6115-6195 MHz) * **Channel 85** (6195-6275 MHz)
