A range of companies with wireless LANs are discovering that 50% to 90% or more of Ethernet ports go unused because Wi-Fi has become so prevalent.rnThey 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 users have already discarded - the Ethernet cable?
