coondoggie writes in with a Network World piece that begins "A range of companies with wireless LANs are discovering that 50% to 90% or more of Ethernet ports now go unused, because Wi-Fi has become so prevalent. They look at racks of unused switches, ports, Ethernet wall jacks, the cabling that connects them all, the yearly maintenance charges for unused switches, electrical charges, and cooling costs. So why not formally drop what many end users have already discarded — the Ethernet cable? 'There's definitely a right-sizing going on,' says Michael King, research director, mobile and wireless, for Gartner. 'By 2011, 70% of all net new ports will be wireless. People are saying, "we don't need to be spending so much on a wired infrastructure if no one is using it."' ... There is debate over whether WLANs, including the high-throughput 802.11n networks, will be able to deliver enough bandwidth." Cisco, which makes both wireless and wired gear, has a spokesman quoted calling this idea of right-sizing a "shortsighted message from a wireless-only provider. It's penny-wise and pound-foolish."
