Just what the world needs: another consortium promoting a wireless technology for the transmission of HD content in the home. The latest is the Wireless Home Digital Interface (WHDI), launched today by Sony, Samsung, Hitachi, Motorola and Sharp. WHDI's technology comes from Israeli company Amimon. It uses the 5GHz band to transmit uncompressed 1080p video, audio and control signals around the home from multiple sources to multiple receivers. All this data is beamed at up to 3Gb/s. Amimon claimed WHDI's range is 30.5m. It can go through walls and has a latency of less than a millisecond. [MORE] -- Best regards, FAQ for Wireless Internet: <http://wireless.navas.us>

Now where, oh where, do you suppose they came up with that wierd figure of "30.5 meters"? You don't suppose they've converted from a nice round number in some other measuring system, doyathink? -- _____________________________________________________ Knowledge may be power, but communications is the key dannyb@panix.com [to foil spammers, my address has been double rot-13 encoded] | |||||||||||||

Yup, it's 100 feet.

>a nice round number in some other measuring >system, doyathink? Nope. It's suppose to go through walls. They probably paced it off until they hit a wall, walked around to the other side, and continued pacing. Another possibility is that they used one of those ultrasonic measuring tapes. They read off in tenths of a meter. Yet another possibility is that they couldn't decide if they should round the 0.5 up or down. Of course, the article didn't mention if it was actually usable at 30.5 meters, or whether the error rate was sufficient to irritate the avearge TV user. Most users can tolerate quite a bit of garbled audio (i.e. cell phones, VoIP), but even a few artifacts on the HDTV screen will produce an irate phone call to the cable or satellite providers outsourced support provider. -- Jeff Liebermann jeffl@cruzio.com 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 | |||||||||||||
