I believe with VHT (40Mhz bandwidth) it will cover 1 channel above and below, but it might be 1 above and 2 below
- I don't recall enough information to provide a technical answer, but if I recall correctly:
- If Channel 157 is selected, it will cover 153, 157, & 161, whereas if Channel 153 is selected, it would cover 149, 153, & 157
- If Channel 157 is selected, it will cover 153, 157, & 161, whereas if Channel 153 is selected, it would cover 149, 153, & 157
However, if HT [20MHz bandwidth] is chosen, it would only utilize the specific channel selected.
- HT will halve your throughput
