Well, the devices I posted about are FPGAs, which stands for field programmable gate array. In short, they are an array of logic gates which you can program to do anything you want. The biggest manufacturers of FPGAs are Xilinx and Altera. I'm only familar with the Xilinx parts. In a Xilinx FPGA, there is a regular array of rows and columns of things called "configurable logic blocks" (CLBs). Each CLB contains a couple of flip flops and a couple of look up tables (LUTs). The LUTs are effectively logic gates. (And they can be used as RAM or ROM on some chips.) In between the CLBs are nets connecting CLBs together. When designing for an FPGA, you draw your design using a schematic editor. (You can also enter it using a hardware description language such as VHDL, Verilog or AHDL, but that's another story.) Once you have entered the design, you use tools supplied by the chip vendor to "place and route" the design onto the chip. Basically, the software works out where each logic gate in your design should be placed on the chip, then works out how to connect the logic gates together, using the fixed resources inside the chip. The Xilinx FPGAs are reprogrammable and in fact must be programmed every time you power them on. They do not contain any flash memory to store your design. Altera have a similar design with LEs (logic elements) instead of CLBs, etc. The contents of a Xilinx CLB change between different chip families too; the older 4000 and Spartan families had two flip flops per CLB, but a Virtex or Spartan-II has 4. The web site http://www.optimagic.com/ may have some more information.

I was initially thinking about the PN sequence generation, BPSK modulation, received PN sequence synchronization, etc. There was a demonstration board described in a 1986 QEX article which mapped quite well straight into an FPGA. You could do this stuff with a normal DSP, although probably not a cheap one. The advantage (in my opinion) of FPGA is that it is so parallel. The FPGA can do all those tasks at the same time, while the DSP has a limited number of clocks cycles between samples to get everything done.

In the context of a "software radio" we simply use a wonderful analog-digital converter (the kind made from non-obtanium, I guess :-) and feed the bits into a digital signal processor. It then implements the oscillators, mixers, filters, modulators, demodulators, etc. Some of this might be done by the FPGA, some by a general purpose processor (e.g., Pentium) or perhaps a dedicated, traditional DSP (e.g., Motorola or Analog Devices or T.I.). I think the excitement/interest level here is sparked by the dramatic price reductions just put in place by Xilinx. We're talking a factor of about 5 here, along with significant performance gains and reductions in power consumption. Enjoy!

I have never used them, but they sound very interesting and versatile. I used to do a lot of building in the 60's and 70's mostly TUs for RTTY and associated logic stuff (SELCAL etc). I am hoping to find some ethernet WLAN cards and play with them. Several people in the area have expressed an ineterest in getting a SS group going here on 900 MHz, but no one has actually done anything on it as yet. I doubt that the others do any building etc, so if we can find something that is somewhat complete, I can get them going and we can take it from there. I received a response suggesting I might try Frys electronics in Phoenix. Have been in there gigantic store several times, but never thought they might be a source for these cards. I will check into that and see what they might have. Thanks again for your response. I will be keeping watch on the reflector for addittional information. 73, Paul W8OX ----- Original Message ----- From: Hamish Moffatt To: TAPR Spread Spectrum Special Interest Group Sent: Tuesday, July 04, 2000 3:21 PM Subject: [ss] Re: (fwd) Spartan II availability and pricing On Tue, Jul 04, 2000 at 10:15:57AM -0700, PAUL VAN WIE wrote: > I am just getting into SS, and am not familiar with all these chips.

Well, the devices I posted about are FPGAs, which stands for field programmable gate array. In short, they are an array of logic gates which you can program to do anything you want. The biggest manufacturers of FPGAs are Xilinx and Altera. I'm only familar with the Xilinx parts. In a Xilinx FPGA, there is a regular array of rows and columns of things called "configurable logic blocks" (CLBs). Each CLB contains a couple of flip flops and a couple of look up tables (LUTs). The LUTs are effectively logic gates. (And they can be used as RAM or ROM on some chips.) In between the CLBs are nets connecting CLBs together. When designing for an FPGA, you draw your design using a schematic editor. (You can also enter it using a hardware description language such as VHDL, Verilog or AHDL, but that's another story.) Once you have entered the design, you use tools supplied by the chip vendor to "place and route" the design onto the chip. Basically, the software works out where each logic gate in your design should be placed on the chip, then works out how to connect the logic gates together, using the fixed resources inside the chip. The Xilinx FPGAs are reprogrammable and in fact must be programmed every time you power them on. They do not contain any flash memory to store your design. Altera have a similar design with LEs (logic elements) instead of CLBs, etc. The contents of a Xilinx CLB change between different chip families too; the older 4000 and Spartan families had two flip flops per CLB, but a Virtex or Spartan-II has 4. The web site http://www.optimagic.com/ may have some more information.

Internally, the chip spins up a clock to 88 MHz (11.36 ns). This clock is used to align the receiver to the incoming chips and to generate an 11 MHz rx data clock. The rx clock is synchronous to the local 88 MHz but jump in phase by +/- 11 ns as needed to center the data and match differences in transmitter frequency. In addition, the clock phase has some jumps at 512 bit intervals. The net effect is to produce an 11 MHz output clock with some jitter on the edges I think this characteristic puts a limit on the accuracy of signal timing that falls short of your requirement by about 2:1. jeff wa1hco ----- Original Message ----- From: "Paul Sadowski" To: "TAPR Spread Spectrum Special Interest Group" Sent: Friday, July 07, 2000 10:17 PM Subject: [ss] Looking for Accurate Time "Hack" w/802.11 > I'm stumped and figured this group could give me a hint or two...

Unlike the uwb and bluetooth folks, they appear to be shipping(?). I suspect SS is not at all involved here, the 30 channels may be just that, channels and not what the unit hops on. Might just have been for cost considerations.... I'm sure they would want more range if they could get it. Notice, they also allow anyone to be a developer..... Thanks for the URL. -Jeff "William C.

They appear VERY open to ideas and recommendations. Indeed the RF deck is a deck out of a 900 MHz discrete channel phone (as told to me by them) there are 30 selectable channels and according to the propaganda each channel can support up to 100 interconnected users. For those who do not think much of it, I guess it ain't much but like my grandmomma said one day, "wish in one hand and spit in the other and see which fills the fastest", some times I think we do a lot of wishing and not enough spittin', so here we stand empty handed, and some company out there is bringing out the beginnings of the box we have been wishing for. In talking to them they sounded like the would like to develop a device and a network concept that would be like the ricochet system, or a cell like system, but they were VERY open to ideas and recommendations. They also want to do voice, but do not handle it yet. I believe the sound part is all there it is probably a software issue. I will repeat my self again, if we want to get some volume on these things we are going to have to get the volume radio users (voice users) involved, or I fear we will continue to spend a lot of time wishing. I totally favor a data world, but reality is that the world is a voice world, and the best way to get volume is to convert that voice into a data stream and then do neat magic with it that will make the voice users want to get on your system, pay the (insert monetary unit here) to do so and keep from draining YOUR pocket so much. Yes this box is crude and rude but, it is a start. I can probably do better with a Casio Cassiopeia (sp?) with a PC card slot full of radio, some software in there to handle the voice part and a access point well place on top of my building to use it a few hundred yards from the building, but the cost is now up there at over 1K USD. If they can keep the cost on this down near where it is now, and still field a SS device that can work through a hub or SS repeater, and carry a bit of power behind it (up to the 1 watt part 15 max) then they are really going the right direction for the volume user. Go out and look at the web site, give them a call, or a e-mail and see what you make of it. --- You are currently subscribed to ss as: lyris.ss@tapr.org To unsubscribe send a blank email to leave-ss-6751T@lists.tapr.org From bounce-ss-6751@lists.tapr.org Fri Jul 14 10:28:01 2000 Received: from lists.tapr.org (lists.tapr.org [204.17.217.24]) by tapr.org (8.9.3/8.9.3/1.13) with SMTP id KAA11486 for ; Fri, 14 Jul 2000 10:27:54 -0500 (CDT) Message-ID: From: "Paul McInnish" TO: "TAPR Spread Spectrum Special Interest Group" References: Subject: [ss] Re: Right Direction Date: Fri, 14 Jul 2000 11:21:49 -0400 Organization: Digital Wireless Corporation MIME-Version: 1.0 Content-Type: multipart/alternative; boundary="----=_NextPart_000_04CC_01BFED85.B40939C0" X-Priority: 3 X-MSMail-Priority: Normal X-MimeOLE: Produced By Microsoft MimeOLE V5.50.4133.2400 X-MDaemon-Deliver-To: ss@lists.tapr.org X-Return-Path: pmcinnish@digiwrls.com List-Unsubscribe: List-Software: Lyris Server version 3.0 List-Subscribe: List-Owner: X-List-Host: Tucson Amateur Packet Radio Reply-To: "TAPR Spread Spectrum Special Interest Group" X-Message-Id: <04cf01bfeda7$3b5dfd40$3a00a8c0@oemcomputer> Sender: bounce-ss-6751@lists.tapr.org Precedence: bulk This is a multi-part message in MIME format. ------=_NextPart_000_04CC_01BFED85.B40939C0 Content-Type: text/plain; charset="Windows-1252" Content-Transfer-Encoding: quoted-printable See response embedded below: Paul McInnish - K4BET Manager, Business Development Digital Wireless Corp.

I listed to the 900 MHz band almost daily, and hear nothing, or see nothing on the analyser. Of course I am in a rural area. We do have several pagers around 931. The rest of it is very quiet.

A small amount of crud can cause havoc! Assume one is using a frequency hopping digital spread spectrum transceiver sending/receiving life support monitoring data... the throughput can be severely slowed down as the transceiver makes every effort to receive all the data and with all the error checking the transceiver is having to do... well, I sure would not want that! Or you are controlling several dozen fully automated robotic production lines... some dropped data, some erred data... some flawed data... the robotics either shuts down, goes havoc, etc., etc..... Critical digital data cannot tolerate trash! Even small amounts! And some speed requirements are also critical! Noise, interference & jamming slows the digital system down, dramatically. As I previously stated... the reasons we chose to get out of the 900 MHz ISM band is precisely because of all the noise & interference... even @ 2.4GHZ it is there but we control that with DSP, hard filtering, soft filtering, very sharp band skirts, etc. AND we can ship product all over the world! 900 MHz is restricted only to USA, Canada & Mexico!

The whole world has paging systems operating in the 400 MHz band... the keyless entry, MTS paging, (some of these systems run 300 watts ERP) etc., etc. are in the high end of 450 - 500 MHz.... simple math times two puts the first harmonic in the 900 ISM band... other frequencies falling right out side (above - below the 900 MHz band) beating with other services also creates a ton of crud!

I am trying to use One VSAT antenna for 3 remote site in Bangladesh. Each site has 10 lines, and want to connect them so that they all link up with the main site and use the one antenna. I also need to know can we use one multiplexer at the main site and interconnect via spread spectrum or do we need 3 multipledxers each at one site. We are trying to connect our UK offices to Bangladesh and want to know the best and cost effective way to do it. We certainly don't want to put up 3 VSAT antenna each at one site, which certainly will drive up our cost. Thanking you in advance for your recommendations.

The 19th Annual ARRL and TAPR Digital Communications Conference will be held September 22-24, 2000, in Orlando, Florida - just minutes from the Orlando International Airport. The ARRL and TAPR Digital Communications Conference is an international forum for radio amateurs in digital communications, networking, and related technologies to meet, publish their work, and present new ideas and techniques for discussion. Presenters and attendees will have the opportunity to exchange ideas and learn about recent hardware and software advances, theories, experimental results, and practical applications. The Digital Communications Conference is not just for the digital expert, but also for digitally oriented amateurs of all levels of experience. A Conference for the Beginner as well The conference is not just for the digital expert. As in years past an entire session strand with beginning, intermediate, and advanced presentations on selected topics in digital communications will be offered. Some of the topics will include: APRS, Satellite Communications, TCP/IP, Digital Radio, Spread Spectrum and other introductory topics. Come to the conference and hear these topics presented by the experts! Area Attractions The Orlando Florida area is famous for its attractions and vacation spots. Disney World, Universal Studios, and Sea World (just to name a few) are within 15 minutes of the hotel. Shuttle service from the hotel will be available for a small fee. Cape Canaveral and Cocoa Beach are a 30 minute drive East of the hotel. Symposia, Seminars and Banquet Two symposia/seminars will be held which allow those with additional time and interest to make the most of the Conference. For those who may have interest in just one symposium or seminar, registration for the conference is not required to attend these activities. This allows maximum flexibility for those who may want to participate during the Digital Communications Conference, but do not have an entire weekend to devote to the event. The Fourth APRS National Symposium will be held on Friday and will be moderated by Steve Dimse, K4HG (the developer of javAPRS). It will likely include many APRS software authors, such as Bob Bruninga, WB4APR (the father ofAPRS), Keith Sproul, WU2Z, Mark Sproul, KB2ICI (the developers of MacAPRS and WinAPRS), Brent Hildebrand, KH2Z (the developer of APRSPLUS), Mike Musick, N0QBF (developer of PocketAPRS), and other nationally known APRS leaders. Join this group for the afternoon and evening for in-depth discussions and presentations on the current and future status of APRS. This is a unique opportunity to gain insight into this fast-growing digital aspect of amateur operations that combines computers, packet radio, and GPS (Global Positioning System). On Saturday night the DCC Banquet will be held. A guest speaker will speak after the banquet and a prize drawing will top the evening. The Grand Prize is a Palm VII Personal Digital Assistant. The Sunday morning seminar will be focused on PIC development, design, and programming. This five-and-a-half hour seminar will focus on the things you need to know now in order to understand and begin to participate in PIC development. Co-Hosts The 2000 ARRL and TAPR Digital Communications Conference local co- hosts will be Lake Monroe Amateur Radio Society (http://www.qsl.net/lmars/),Orange County ARES/RACES(http://evcom.net/~jvoisin/ares.htm), Seminole County ARES/RACES (http://wwww.geocities.com/capecanaveral/launchpad/4773), and Orlando Amateur Radio Club(http://www.oarc.org/).

The 19th Annual ARRL and TAPR Digital Communications Conference will be held September 22-24, 2000, in Orlando, Florida - just minutes from the Orlando International Airport. The ARRL and TAPR Digital Communications Conference is an international forum for radio amateurs in digital communications, networking, and related technologies to meet, publish their work, and present new ideas and techniques for discussion. Presenters and attendees will have the opportunity to exchange ideas and learn about recent hardware and software advances, theories, experimental results, and practical applications. The Digital Communications Conference is not just for the digital expert, but also for digitally oriented amateurs of all levels of experience. A Conference for the Beginner as well The conference is not just for the digital expert. As in years past an entire session strand with beginning, intermediate, and advanced presentations on selected topics in digital communications will be offered. Some of the topics will include: APRS, Satellite Communications, TCP/IP, Digital Radio, Spread Spectrum and other introductory topics. Come to the conference and hear these topics presented by the experts! Area Attractions The Orlando Florida area is famous for its attractions and vacation spots. Disney World, Universal Studios, and Sea World (just to name a few) are within 15 minutes of the hotel. Shuttle service from the hotel will be available for a small fee. Cape Canaveral and Cocoa Beach are a 30 minute drive East of the hotel. Symposia, Seminars and Banquet Two symposia/seminars will be held which allow those with additional time and interest to make the most of the Conference. For those who may have interest in just one symposium or seminar, registration for the conference is not required to attend these activities. This allows maximum flexibility for those who may want to participate during the Digital Communications Conference, but do not have an entire weekend to devote to the event. The Fourth APRS National Symposium will be held on Friday and will be moderated by Steve Dimse, K4HG (the developer of javAPRS). It will likely include many APRS software authors, such as Bob Bruninga, WB4APR (the father ofAPRS), Keith Sproul, WU2Z, Mark Sproul, KB2ICI (the developers of MacAPRS and WinAPRS), Brent Hildebrand, KH2Z (the developer of APRSPLUS), Mike Musick, N0QBF (developer of PocketAPRS), and other nationally known APRS leaders. Join this group for the afternoon and evening for in-depth discussions and presentations on the current and future status of APRS. This is a unique opportunity to gain insight into this fast-growing digital aspect of amateur operations that combines computers, packet radio, and GPS (Global Positioning System). On Saturday night the DCC Banquet will be held. A guest speaker will speak after the banquet and a prize drawing will top the evening. The Grand Prize is a Palm VII Personal Digital Assistant. The Sunday morning seminar will be focused on PIC development, design, and programming. This five-and-a-half hour seminar will focus on the things you need to know now in order to understand and begin to participate in PIC development. Co-Hosts The 2000 ARRL and TAPR Digital Communications Conference local co- hosts will be Lake Monroe Amateur Radio Society (http://www.qsl.net/lmars/),Orange County ARES/RACES(http://evcom.net/~jvoisin/ares.htm), Seminole County ARES/RACES (http://wwww.geocities.com/capecanaveral/launchpad/4773), and Orlando Amateur Radio Club(http://www.oarc.org/).

The 19th Annual ARRL and TAPR Digital Communications Conference will be held September 22-24, 2000, in Orlando, Florida - just minutes from the Orlando International Airport. The ARRL and TAPR Digital Communications Conference is an international forum for radio amateurs in digital communications, networking, and related technologies to meet, publish their work, and present new ideas and techniques for discussion. Presenters and attendees will have the opportunity to exchange ideas and learn about recent hardware and software advances, theories, experimental results, and practical applications. The Digital Communications Conference is not just for the digital expert, but also for digitally oriented amateurs of all levels of experience. A Conference for the Beginner as well The conference is not just for the digital expert. As in years past an entire session strand with beginning, intermediate, and advanced presentations on selected topics in digital communications will be offered. Some of the topics will include: APRS, Satellite Communications, TCP/IP, Digital Radio, Spread Spectrum and other introductory topics. Come to the conference and hear these topics presented by the experts! Area Attractions The Orlando Florida area is famous for its attractions and vacation spots. Disney World, Universal Studios, and Sea World (just to name a few) are within 15 minutes of the hotel. Shuttle service from the hotel will be available for a small fee. Cape Canaveral and Cocoa Beach are a 30 minute drive East of the hotel. Symposia, Seminars and Banquet Two symposia/seminars will be held which allow those with additional time and interest to make the most of the Conference. For those who may have interest in just one symposium or seminar, registration for the conference is not required to attend these activities. This allows maximum flexibility for those who may want to participate during the Digital Communications Conference, but do not have an entire weekend to devote to the event. The Fourth APRS National Symposium will be held on Friday and will be moderated by Steve Dimse, K4HG (the developer of javAPRS). It will likely include many APRS software authors, such as Bob Bruninga, WB4APR (the father ofAPRS), Keith Sproul, WU2Z, Mark Sproul, KB2ICI (the developers of MacAPRS and WinAPRS), Brent Hildebrand, KH2Z (the developer of APRSPLUS), Mike Musick, N0QBF (developer of PocketAPRS), and other nationally known APRS leaders. Join this group for the afternoon and evening for in-depth discussions and presentations on the current and future status of APRS. This is a unique opportunity to gain insight into this fast-growing digital aspect of amateur operations that combines computers, packet radio, and GPS (Global Positioning System). On Saturday night the DCC Banquet will be held. A guest speaker will speak after the banquet and a prize drawing will top the evening. The Grand Prize is a Palm VII Personal Digital Assistant. The Sunday morning seminar will be focused on PIC development, design, and programming. This five-and-a-half hour seminar will focus on the things you need to know now in order to understand and begin to participate in PIC development.

The BRs are my internet connection, so everything, including my webcams and Axis cams (see below) run over it. I have done _mobile_ video with Nova Engineering NovaRoam 900 mhz DSSS wireless routers. That works pretty well, too, but the Nova units are slower than 802.11B, up to 1.008 Mb. www.nova-eng.com The easiest way I have found to integrate this is with Axis 2100 network cameras. These are an entire digital camera and Linux server in a camera housing. They have 10/100 baseT ethernet jacks, serial ports and a discrete input and output, and run on 12vdc. www.axis.com On a fast connection, like 802.11B, the Axis cameras can serve up to 10 video streams at up to 10 frames per second. They can be throttled to whatever speed you need for their connection. BTW, one of the purposes listed for this list is reviewing current ss devices. Is anyone interested in hearing more about the NovaRoams?

Is anyone interested in hearing more about the NovaRoams? I would be interested. I would also be interested in hearing opinions on path issues. This is something I'm very interested in because I want to run a link between my house and friends. We are 1.1 mi. apart with no earth obstructions but we are both significantly overshadowed by trees. I would have to guess that approximately 30 percent of the path would be through trees. Towers are not an option given that these are hundred foot pines. My current level of understanding leads me to believe that 2.4 GHz won't make it but 900 MHz might. I would be really interested in hearing if there are simple/cheap ways of testing out paths for situations like this. ---eric --- You are currently subscribed to ss as: lyris.ss@tapr.org To unsubscribe send a blank email to leave-ss-6751T@lists.tapr.org From bounce-ss-6751@lists.tapr.org Mon Jul 31 11:11:37 2000 Received: from lists.tapr.org (lists.tapr.org [204.17.217.24]) by tapr.org (8.9.3/8.9.3/1.13) with SMTP id LAA04060 for ; Mon, 31 Jul 2000 11:11:36 -0500 (CDT) Message-Id: X-Sender: hansen@postoffice.cc.fredonia.edu Date: Mon, 31 Jul 2000 12:11:27 -0400 To: "TAPR Spread Spectrum Special Interest Group" From: John Hansen Subject: [ss] Re: Nova Wireless routers and Re: Video over Wireless LAN In-Reply-To: References: Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii"; format=flowed List-Unsubscribe: List-Software: Lyris Server version 3.0 List-Subscribe: List-Owner: X-List-Host: Tucson Amateur Packet Radio Reply-To: "TAPR Spread Spectrum Special Interest Group" X-Message-Id: <4.3.2.7.2.20000731121051.02ca24e0@postoffice.cc.fredonia.edu> Sender: bounce-ss-6751@lists.tapr.org Precedence: bulk At 07:15 AM 7/31/00 -0700, you wrote: >I have done _mobile_ video with Nova Engineering NovaRoam 900 mhz DSSS >wireless routers.

They list for about $1900, but I can discount that some, especially for amateurs or in quantities. They come with a 12v power supply, and Nova sells type accepted mag mount, omni and Yagi base antennas, and a rubber duck. Also mobile mounting brackets, and 12vdc power cords with lighter plugs. The units have a reverse TNC antenna connection, RJ45 network jack and a serial port for programming. The serial port can also be routed separately from the ethernet, to create a wireless serial connection. Each unit can be set up to repeat, also.
