Most vendors recommend simply swapping each of my existing legacy APs with an 802.11n AP. Is this a good 802.11n migration strategy?

Deploying 802.11n requires careful planning. Swapping each legacy AP with an 802.11n AP may not be necessary or in fact may even be detrimental due to increased contention or interference among your APs, thanks to the better coverage range of 802.11n APs. To get improvement in capacity, you should also upgrade your clients to 802.11n.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
