UWB fight position with Wi-Fi and Powerline

Saturday, January 13, 2007

Many networking vendors are clashing to decide what technology is the best for delivering high quality for streaming high definition video. High definition video technology, HDTV, generally refers to any higher resolution video system than standard-definition (SD), such as NTSC, PAL, and SECAM.

The latest wireless technology (802.11n standard) is still considered very difficult for delivering the high quality service of streaming HDTV. The 802.11n standard may be the best used for sharing data, however streaming video should be handled by higher speed technologies, such as powerline. But as we know, powerline technology still using cable, ironically lots of people want to get rid of those tangled mess of cable out of their rooms.

Reversely, wireless vendors have different perspectives, they think Wi-Fi will have great prospective in the future. D-Link as one of the networking wireless vendors, introduced the latest routers which support 802.11n standard. It is manufactured in the 5 GHz frequency, as well as in 2.4 GHz. The executives claimed that they focused the performance quality by prioritizing voice and video transmitting. They believe the improvisation will greatly help Wi-Fi to the next stage in enhancing video streaming.

Both existing technology Wi-Fi and powerline are capable of delivering support for HDTV. There is not much difference in price between those products. However, they have their own advantages over each other.

On the other hand, there is another consideration to look over the new technologies, ultrawideband (UWB) technology. UWB is able to transmit data spread over more than 500 MHz bandwidth and able to share spectrum with other users. Tzero Technologies, the pioneer, claimed that UWB can provide higher performance than the two existing technologies. It has greater speed to maintain the stream of HDTV. Furthermore, there is plan to enhance the services to support fast forward and rewind.

Furthermore, there is another potential solution, you will be able to share entertainment content over coaxial cable. Both UWB and powerline technology can run through this coaxial cable.

In the end, no matter what, there must be a persist standard that will greatly support people to enjoy HDTV.
