Some weekend reading: It is a beautiful day here in Chicago - bright sun, a few puffy clouds, several fleets of sailboats on the horizon. Unfortunately my laptop screen is not bright enough to see in bright sunlight.. There are a couple of pertinent articles in the Sept 99 issue of IEEE Spectrum spectrum.ieee.org (unfortunately, the current issue is only available to IEEE members, but I think that the paper pub is available at the newstand). One article titled "A second wind for wiring" talks about ADSL and some of its quirks - splitters, loading coils, etc. They mention a downstream rate of 6.144 Mb/s at a distance of 3.6 km using DMT in one of the data tables, but most are below 1 Mb/s. An interesting quote from the article: "We recognized early that ADSL technology is well suited to help service providers take advantage of this model" he explained, "because it is a scalable broadband technology that integrates with the ATM layer and can maintain the quality of service needed to deliver a wide range of applications". This was a quote from Enzo Signore, senior product line manager at Cisco. ----- Another article in the same issue "Fixed wireless routes for Internet access". gives the names of many of the equipment suppliers (did not see Stanford though..) Moore's Law applied to radio shows that channel capacity has been doubling every 3 years while the cost is dropping by half every 7 years. Therefore cost per channel drops 50% every 2.1 years. Also, the cost split for LMDS between construction and equipment is 20:80 whereas fixed fiber-in-the-street is 90:10 according to William T. Vogel, senior VP at WinStar Communications, Inc. Some web site addresses in the reference section: tr.com - Telecommunications Research International a quote from one of their newsletters: September 9, 1999 North Dakota PSC Ruling May Spur Wireless Local Loop Service Offerings Prospects for the spread of wireless local loop technology in the U.S. appear to have brightened following a decision last week by the North Dakota Public Service Commission. It said federal law preempts state commissions from regulating market entry and rates of fixed CMRS (commercial mobile radio service) or wireless local loop service. brp.com - seems to be redirected to www.tr.com fcc.gov - map of LMDS frequencies see also ntia.doc.gov OSM is Office of Spectrum Management. --- This Spectrum issue also has a profile on Henry Samueli, one of the co-founders of Broadcom.
