60 GHz could be used for home video distributionSiBeam Inc has revealed some details of it’s 60 GHz technology that can be used to transfer video and data at up to 5 Gbits per second with a range of 10 metres. It would appear to provide a possible alternative to Ultra Wideband (UWB). Article from http://www.eetimes.eu/200000922 SiBeam takes wraps off Wireless HD technology LONDON — Gigabit wireless technology startup SiBeam Inc. has revealed some details of the 60GHz technology that it and partners in the WirelessHD consortium plan to deploy to deliver a promised gigabit per second of multimedia content wirelessly in the home. Dubbed OmniLink60 and made in a standard CMOS process, the working chipsets
will deliver non-line-of-sight beam steering and A/V connectivity for
wireless video networks. SiBeam revealed Wednesday (June 27) that it developed both successful transmit and receiver 60 GHz chipsets in CMOS as far back as 2005. The Wireless HD Consortium was formed late October 2006 and also includes
LG Electronics Inc., Matsushita Electric Industrial Co., Ltd., NEC Corp.,
Samsung Electronics, Co., Ltd, Sony Corp. and Toshiba Corp. to develop
a technology that will handle secure near line-of-sight communications
with smart antenna technology across a 10 meter range. The spec, full details of which are expected to be announced within months, also aims to address file transfers between camcorders, cameras, DVD recorders and TVs. Latency should be as little as 5 to 15 milliseconds. SiBeam claims it is the first company to build working 60 GHz chips
in standard CMOS and says it achieved several breakthroughs in developing
OmniLink60 technology, including CMOS modeling at millimeter wave frequencies,
multi-element antenna technology and enabling non-line-of-sight functionality
for A/V applications at the 60 GHz band. "We’ve conquered some of the industry’s most challenging
obstacles surrounding 60 GHz. Our aim with this technology is to exploit
the 7 GHz of unlicensed spectrum around 60 GHz to provide very high data
rates to multiple users within an indoor wireless environment using conventional
silicon," said John LeMoncheck, SiBeam CEO. Non-line-of-sight functionality is a critical component of the new OmniLink60 technology, says LeMonchek. The technology incorporates micro array antenna technology to dynamically establish the optimal path from a signal source, such as a set-top box, to a receiving device, such as an HDTV. When the antenna detects a weakening signal due to an obstruction like a person walking in the signal’s path, it automatically re-surveys the environment for a new, best path and adjusts the beam without disruption in the signal's transmission. The company says each SiBeam-enabled device will be able to be aware
of not only other devices in the network, but will also be aware of that
device's capabilities, such as whether it is a digital video camera, game
console, digital camera or camcorder or set-top box. It adds the 60 GHz
band offers the spectral availability for true uncompressed HD video,
audio and data transmission, scalable to future HD A/V formats. Related Links:
