This document provides a technical overview of Cisco's MultiGigabit Ethernet technology. It discusses how existing Gigabit Ethernet infrastructure is insufficient to support wireless speeds beyond 1 Gbps. Cisco's MultiGigabit technology allows speeds of 2.5 Gbps and 5 Gbps over existing Cat5e cabling without replacing the infrastructure. It also details Cisco's MultiGigabit product family including line cards, switches, and supported speeds.
