Eric L: You mentioned you would look at Netro's "time division" point to multipoint. LU and Siemens use Netro now. This story seems to be a "stealth" story on the use of Netro's technology by AT&T. Curious what you think. qdog Your views would be particularly interesting and informative if you care to comment. Best to you both. Chaz Talk : Communications : Netro Corp - (NTRO) To: CRUSADER4TRUTH (472 ) From: CRUSADER4TRUTH Sunday, Oct 24 1999 8:02PM ET Reply # of 477 The company's Business Services unit has amassed licenses that allow it to use wireless spectrum in 305 markets to deliver the package of switched voice, frame relay, Asynchronous Transfer Mode and Internet Protocol services envisioned in its recently announced Integrated Network Connection (INC) plan. Sources said the company is exploring use of advanced radio technology, being developed through its "Project Angel" initiative, to increase bandwidth efficiency and system performance at the very high frequency tiers in the 38-gigahertz spectrum zone covered by these licenses. <P>The company has been using point-to-point wireless connections at 38 GHz to quickly connect customers that aren't immediately reachable via wireline facilities, said Roger Cawley, a spokesman for Business Services. This strategy follows a pattern set by Teleport Communications Group through its acquisition of 38-GHz licensee BizTel prior to AT&T's purchase of TCG last year. <P>Now, Cawley said, AT&T is evaluating point-to-multipoint systems, such as those used by WinStar Communications at the 38-GHz tier and by Teligent at 24 GHz for delivering fixed dedicated services - essentially a wireless private line - from transmitters over market areas measuring about three miles in diameter. "We're probably looking at the machines coming out of beta testing at Lucent [Technologies]," he said. {insertNTRO} <P>Point-to-multipoint systems allow hundreds of users to be served from a single transmitter, rather than linking only one user per transmitter in the point-to-point mode. This new wireless broadband technology allows service providers to deliver all types of services in two-way mode to building-mounted antennas. <P>In most markets, AT&T has only 100 megahertz of bandwidth available within the 38-GHz spectrum, which is less bandwidth to work with than Teligent and WinStar have with spectrum allocations averaging 400 MHz and 500 MHz, respectively, in their major markets. But AT&T's Project Angel technology - developed for use at the personal communications services (PCS) spectrum tier of 1.9 MHz - can be used to accomplish much higher data rates over a given slice of raw wireless bandwidth than is possible with platforms used by other wireless carriers, said a source with knowledge of AT&T's plans. <P>"They are just waiting for the Project Angel development phase to be completed, and then they'll be able to move ahead with a very robust, bandwidth-efficient platform at 38 GHz," the source said. <P>But Robert Annunziata, president of Business Services and former TCG chief executive officer, mentioned at the recent Comnet conference, that the company was weighing use of Project Angel technology in conjunction with the INC initiative. Senior spokesman Tom Holub said company interest in applying the technology for a variety of applications beyond the original PCS strategy was driven by the fact that "the cost points are dropping and, as a result, it's becoming more and more viable." </SPAN><P>zdnet.com .
