Mark, well New Media's Cyberstream is a one way system,so it works well with that. It depends on what medium and what country. It is a good system for MMDS/LMDS or Satellite.Satellite bandwidth is extremely inefficient compared to either microwave or fiber. I doubt that Satellite will be 2-way,the uplink bandwidth is very small. It is a good system for those who do not wish to upgrade their cable plants. Only affluent areas of America with have 2-way HFC in the near future. I doubt they will have 2-way in Bangladesh any time in the near future. Tim

Mark, here is one article,have to go back to copy the other one. multichannel.com Tony Werner, executive vice president of engineering and technical operations for AT&T Broadband & Internet Services (formerly Tele-Communications Inc.), raised a stir by describing how his MSO plans to test a "micro-node" cable-telephony architecture that pushes fiber optic transmission to network depths of 50 to 75 homes passed per node, versus 500 or more under its current architecture. Werner said the technology, developed by AT&T Laboratories, uses digital and optical multiplexing to keep fiber counts low, pushing maintenance and equipment costs down by reducing the number of active components, such as power amplifiers, by 60 percent to 80 percent. He also said the architecture was backward-compatible with AT&T Broadband's existing HFC networks, and it did not necessarily rely on new revenue streams from advanced services to justify deployment. A pilot to determine the new structure's cost-effectiveness will be run in a market he did not disclose, although it was rumored to be Salt Lake City. Colin Boyd, vice president of North American sales and marketing for AT&T supplier Harmonic Inc., saw a lot of foot traffic past such displays as its new "DWDM-through-the-node" return transmitter, which is intended to boost return-path bandwidth by eight wavelengths on a single fiber. Boyd said AT&T Broadband raised operator interest in DWDM. "Let's face it: AT&T's got a lot of influence on the industry right now," he added. HLIT is kicking some cable ass,now it has AT &T's research division to pump it full of information. The freaken sky is the limit now boys. Tim

Mark, here is part of your answer,HLIT is doing a lot of work with multicasting one way Satellite and MMDS type services for distance learning. Yes,it is sort of a dedicated broadcast type system(in my opinion). 5/28/99 - HARMONIC DATA SYSTEMS: CyberStream selected for distance learning in New York and Puerto Rico MAY 28, 1999, M2 Communications - Orlando, Fla -- Today at Cable-Tec Expo '99 Harmonic Data Systems Ltd. (HDS), a subsidiary of Harmonic Inc. (NASDAQ: HLIT) announced that it is partnering with Miralite Communications to equip satellite-delivered distance learning services for K-12 and high school students in both New York State and Puerto Rico. In separate projects with service providers, The State University of New York (SUNY) and the Hispanic Internet and Telecommunications Networks (HITN), Miralite will be installing download terminals that are pre-installed with HDS's CyberStream PC/PCI satellite receiver cards. This enables the high speed of downloads necessary for video and multimedia content delivery to the desktop. Miralite Communications of Newport Beach, Calif, is one of the nation's largest broadcast systems integrators, providing complete satellite networks for delivering MPEG-2 compressed video and Internet data to corporations as well as educational establishments. For the SUNY project Miralite is developing a network to give students and educators fast and easy access to video material which is currently distributed on VHS to schools on an individual basis. The HITN project requires Miralite to build a high-speed Internet service for elementary and secondary schools in Puerto Rico, enabling teachers and pupils to browse the Internet and download content for educational purposes at a rate of 2Mbps. "Our market leadership in the supply of distance learning solutions has been maintained because of our partnerships with vendor products that deliver the superior performance, reliability and flexibility we require," said Kevin Knickerbocker, vice president of sales at Miralite Communications. "The CyberStream receiver card has tested well during the beta phase and has proved to be an excellent component to integrate into distance learning via satellite networks." Tim
