FOCUS Enhancements Demos Wireless, Ultra Wideband Transmission of High-Def TV Streams

] FOCUS Enhancements expects to sample UWB chip-sets in the
] third quarter of 2005 and modules containing UWB
] chip-sets later in the year. Performance expectations are
] anticipated to range from 880 Megabits per second (Mbps)
] at 8 meters to 37 Mbps at around 40-plus meters. This could get interesting. I'm stuck on whether I should just use Cat5 to bridge all my audio/video/data/IR traffic in my house, or start up a company that builds a wireless alternative. I don't think WiFi has the bandwidth and QoS to drive anything other than highly compressed VoIP and/or SD video, but it's EVERYWHERE and the chipsets are dirt cheap. However, UWB looks to be the winner, but has a loooong way to go for must haves like encryption and QoS. a dilemma. |

] What sort of bandwidth is required for high quality video? HD compressed is 30Mhz (or roughly 30Mbits), and uncompressed digital video is over 100, so clearly 11g is barely capable in even ideal conditions. |
