As I understand it, it allows you to do the opposite...it reduces the coverage for better operation in environments where there are a number of APs. When several cells are available to a card, it will pick one and start using it. If there is another with nearly equal signal, it may start flipping between cells and this will damage performance. Setting the AP density to a higher value will adjust the "squelch" to try to reduce/eliminate this problem. Even if you are not flipping channels, near-by APs on close channels may cause interference which the AP density setting should help. But, if you ar trying to extend the range of your system when it is the only system around, this won't help. It will only make it worse. R.
