-The Mango 802.11 Reference Design has a feature to set a minimum packet detection power. By doing so, a user can specify a minimum ''required'' power that must be present before the PHY will attempt to decode a packet. Raising this power requirement can make a receiver intentionally "more deaf." This parameter can be very useful in experiments for eliminating difficult-to-reproduce low-level interference from other Wi-Fi networks. If a user knows that their devices in the experiment are close to one another, they can raise this threshold to keep their receivers from attempting to decode other distant interferers. This is not universally a good idea -- if the research question a user is trying to answer relies on the presence of weak interferers, then this feature may not be appropriate.

By doing so, a user can specify a minimum ''required'' power that must be present before the PHY will attempt to decode a packet. Raising this power requirement can make a receiver intentionally "more deaf." This parameter can be very useful in experiments for eliminating some of the effects of difficult-to-reproduce low-level interference from other Wi-Fi networks. If a user knows that their devices in the experiment are close to one another, they can raise this threshold to keep their receivers from attempting to decode other distant interferers.
