George thanKS for your report I bought Ciena at 13 5/8 and sold 1/3 of my Tellabs. anyway what you think of This claim Motorola's hot wireless TV plan By Tom Steinert-Threlkeld, ZDNet Motorola Inc. is about to bring out of its laboratories a technology in development for five years that allows lifelike interactive television signals to be sent and received wirelessly and instantaneously. Motorola believes it is "years ahead of anyone else" in exploiting parts of the radio spectrum that would allow delivery of interactive television services wirelessly. According to Rudyard Istvan, the company's corporate director of strategy, the technology can operate in nearly any slice of spectrum ranging from 5 billion to 60 billion cycles, or hertz, per second. At present, Motorola appears to be focusing on what Istvan calls a "very, very interesting band" of spectrum that lies just below 60 gigahertz. The company envisions selling huge volumes of small antennae - possibly the size of thermostats - that would be scattered across corporate campuses, public places and streets roughly 15 feet apart, as well as microchips to handle signals and process video. Istvan said Motorola would propose its architecture for this system, which it calls Piano, as an industry standard for delivering high-speed wireless data among personal computers, servers, personal digital assistants, notebook PCs and other digital devices. Using Piano as a standard is being proposed to the Bluetooth Special Interest Group, a consortium of wireless communications and computing companies founded in May by IBM Corp., Intel Corp., Nokia Corp., Telefon AB L.M. Ericsson and Toshiba Corp. While Motorola has not publicly discussed the Piano architecture, the company said it considers the technology to be ready to roll out. "We wouldn't be proposing it [as a standard] if we didn't feel we could implement it now," Istvan said. If adopted, the impact "could be quite large" on data networks, Istvan said. He expects Piano first to extend the use of company networks to the exchange on an instant's notice of video and other multimedia data. Making that possible will be a set of low-cost chips, likely to cost less than $100, that will handle the wireless signals being sent and received from computing and communications devices to the microcell antennae. Also critical to Motorola's plans are new generations of its Merlin digital signal processing chips, which the company expects to have operating at 1 billion cycles per second next year. At that speed, Istvan said, the Merlin chips will be able to compress and decompress motion-picture-quality video without delay, allowing live videoconferences and other video communications to be conducted on a wireless network. The creation of room-sized cells is necessary for the wireless distribution of video if radio waves in or near the 60-GHz band are used because of the characteristics of higher frequencies on the radio spectrum, said Shea Silidker, consultant in the personal communications unit of The Strategis Group Inc. in Washington, D.C. The higher the frequency, the lower the range of signals. To date, most efforts at delivering high-speed data wirelessly have been in the 28-GHz to 38-GHz area. This is uncharted territory. But Motorola has been a pioneer of cellular telephone service, and the Piano architecture is "philosophically" - although not technically - similar to Motorola's efforts to launch satellite networks that can deliver telephone calls, television programming and Internet data. Its Iridium phone network is entering commercial service now; and, the Teledesic LLC network - an Internet in the sky - is set to start up in 2003. Ubiquity for the Piano architecture, though, would mean millions of cells in any major market. But just because the company can begin to deliver the technology and expects it to find acceptance first on corporate networks doesn't ensure its success, said Jane Zweig, executive vice president of Herschel Shosteck Associates Ltd., a wireless consulting firm. "This is really its first effort in this arena," Zweig said. The corporate data network "is going to be a fierce battleground for Motorola." Other wireless players like Ericsson gear providers, such as Lucent Technologies Inc. and Northern Telecom Ltd., also will zero in on providing high-speed wireless networking technology and wired data networks.
