IEEE 802.11n delivers maximum video performance in wireless entertainment applications
A new breed of wireless entertainment network must provide higher bit rates to support the distribution of multiple-quality video and HTDV streams from a central location, along with total home coverage. These video applications cannot tolerate bandwidth fluctuations. Therefore, guaranteed bandwidth and quality of service (QoS) are essential requirements in order to provide wire-like performance regardless of changing environmental conditions....
