I have five 802.11b wireless phones and some "random" 802.11b "laptops" that are on my network. Management does not want to remove 802.11b if there is any possibility of anyone wanting to 802.11b even though there is a "tax" to pay. Let's say I have no 802.11b devices present on my network. How can I give an example to non-technical people to explain what tax they are paying even if there are not 802.11b devices. What can management expect to see in terms of improved network performance that they can relate to. Also do you have a technical paper that I could read that explains in detail these taxes that you have talked about in your article?
