Vector Orthogonal Frequency Division Multiplexing (VOFDM)

Introduction

Vector Orthogonal Frequency Division Multiplexing (VOFDM), developed by Cisco, is an open standard for broadband wireless Internet services. VOFDM increases subscriber coverage for high-speed, high-reliability Internet, packet local and long distance telephony services and Virtual Private Network (VPN) access. VOFDM also lowers the cost of provisioning and deploying infrastructure for a wireless network, and utilizes multipath signals to enhance or recreate transmitted signals, dramatically increasing overall system performance and scalability for service providers. This allows for high data throughput in a minimum of Radio Frequency (RF) spectrum and supports extreme multipath issues existing in obstructed or partially obstructed non-line-of-sight environments.
