Since then, the only people on the list have been those who re-subscribed or started new subscriptions. I had hoped that a backup had been made as part of normal maintenance of the TAPR server, but it seems that none is available. So, I've taken the most recent copy of the subscriber list that I have from before the "incident", and merged it with the current post-incident subscriber list to resurrect the full list (this seems like an appropriate theme for Easter time!). I have spent quite a bit of time searching for and eliminating duplicates from the list, but I may have missed a few. I also may have restored a few people to the list who had previously unsubscribed. This is the best I can do with the information available to me. So, if you receive two copies of this message, or if you don't want to be on the SS list, just send a message to listserv@tapr.org with unsub ss as the first line of text. If you have a problem, drop me a note. And, if you want to talk about spread spectrum, use the list (ss@tapr.org) - that's what it's here for. Let's crank up some activity here again!

Also of note in this issue of SciAm is the theme regarding Wireless Technologies. Of particular interest to members of this group is the article describing Terrestrial Wireless Networks by Alex Hill of CMU (pg86). While the article is broad reaching, Mr. Hill goes on to say that CMU has a wireless network using over 100 Lucent Wavelan boards. Its not clear to me from the article if he was able to bypass the need for the ATT "access points", but if so, he has found a way to put together a inexpensive roaming wireless network. A good read this month. (I think its still on the newstands). -Jeff wb8wka ------------------------------------ | Jeff King Aero Data Systems | | jeff@mich.com P.O.

Since then, the only people on the list have been those who re-subscribed or started new subscriptions. I had hoped that a backup had been made as part of normal maintenance of the TAPR server, but it seems that none is available. So, I've taken the most recent copy of the subscriber list that I have from before the "incident", and merged it with the current post-incident subscriber list to resurrect the full list (this seems like an appropriate theme for Easter time!). I have spent quite a bit of time searching for and eliminating duplicates from the list, but I may have missed a few. I also may have restored a few people to the list who had previously unsubscribed. This is the best I can do with the information available to me. So, if you receive two copies of this message, or if you don't want to be on the SS list, just send a message to listserv@tapr.org with unsub ss as the first line of text. If you have a problem, drop me a note. And, if you want to talk about spread spectrum, use the list (ss@tapr.org) - that's what it's here for. Let's crank up some activity here again!

Also of note in this issue of SciAm is the theme regarding Wireless Technologies. Of particular interest to members of this group is the article describing Terrestrial Wireless Networks by Alex Hill of CMU (pg86). While the article is broad reaching, Mr. Hill goes on to say that CMU has a wireless network using over 100 Lucent Wavelan boards. Its not clear to me from the article if he was able to bypass the need for the ATT "access points", but if so, he has found a way to put together a inexpensive roaming wireless network.

So, if you receive two copies of this message, or if you don't want to be on the SS list, just send a message to listserv@tapr.org with unsub ss as the first line of text. If you have a problem, drop me a note. And, if you want to talk about spread spectrum, use the list (ss@tapr.org) - that's what it's here for. Let's crank up some activity here again!

Ironically, what sparked my interest in the first place was the Scientific American article referred to in recent postings. It could prove to be the answer to a scenario I've been investigating recently. a couple of general questions please : 1. Given the current technology, what is the best range one could achieve (within the 2+ GHz band ?) using non-line-of-site (omnidirectional ?). I would like to achieve 1 - 2 Mbit/sec data rate. Assume no RF holes or enough transceivers to take care of them. I've seen widely varying figures 2. Who are the top manufacturers of equipment for above scenario.

Assume no RF holes or enough > transceivers to take care of them. I've seen widely varying figures You ask what is, in my estimation, a very important, interesting and difficult question. While most of my experimenting has skirted 2 GHz; quite a lot at .9 and 1.3 GHz on the low side and 10 GHz on the high side, I believe my experiences are relevant. I think the single most important part of your question revolves around what you mean by non-line-of-sight. There are secondary issues like "how much directivity", what sort of modulation/encoding/FEC/spreading and how much transmit power but they are all pretty secondary. >From my experiences with 230-500 kbps systems at 900 MHz and ~2 Mbps systems at 10 GHz along with my narrowband experieces throughout the uhf-microwave range I would suggest that the answer to your first question can vary by up to several *orders of magnitude* depending upon the nature and quality of the path(s). 40-60 dB of additional degradation due to non-LOS paths obstructed only by trees, foliage and man-made structures but not by intervening earth is quite common at 900 MHz. Even more than this is commonly seen depending on the specific situation. This translates to a factor of 100 to 1000 times reduction in distance. For some discussion, measurements I've made and a description of an operating system which experiences some of these impediments see: http://www.tapr.org/~n6gn/dcc/problem.html Glenn Elmore n6gn From mitchell@c17m.mdc.com Tue Apr 28 16:46:08 1998 Received: from abyss.mdc.com (ABYSS.LGB.CAL.BOEING.COM [129.200.223.1]) by tapr.org (8.7.5/8.7.3/1.9) with ESMTP id QAA10304; Tue, 28 Apr 1998 16:44:25 -0500 (CDT) Received: from c17m.mdc.com (C17M.MDC.COM [129.200.42.15]) by abyss.mdc.com (8.7.6/8.7.3/CNS-4.0) with SMTP id OAA03606; Tue, 28 Apr 1998 14:39:14 -0700 (PDT) Message-ID: Date: 28 Apr 1998 14:37:29 U From: "Mitchell, Ed C17" Subject: e-mail address To: " Spike " , "ACS" , "admin" , "Adobe" , "Al Jackson(motorola)" , AMELINO.SANDRA_L@LONG-BEACH.VA.GOV, "Arielal@UCI" , "astrotronics" , "Bill Cockey" , "Bill Fitagerald" , "Bittel, Doug" , BumbleB22@aol.com, "Charles Axel Allen" , "Charles Schmid" , "Chris Clark(photobit)" , "Chris Good" , "Dave Rosenthal" , "David Rosenthal" , "Dick Ertman" , "Dik Ertman" , "DMAMUSE" , "Don Hill(tech)" , "Don Jordan" , "Don Pendry" , "donjordan" , "Doug Bittel(analog)" , "Dr. Phil Bos" , "Drew Glista (Navy)" , "DVI" , dvi@adobe.com, "e-mail account" , "ed" , "ed mitchell" , "Elise" , ghelsel/r5_fire@fs.fed.us, "Greg Helsel" , "Heid, Michael" , "home" , "Jgibson111" , Jgibson111@aol.com, "John Desrosiers" , "John Dudd (Allied Signal)" , "Jon Gibson" , "Keith Ellis" , "Konop, James L" , "Laura Blackwell" , "leonard" , "Leonard Monk" To: "Leonard, John CW5" , "Leonard, John CW5 - G3" , "Leonard@home" , "Loralee Lafleur" , "Lou Buck" , "LSBuck" , LSBuck@aol.com, "Mark A.
