To set the stage, the following is the welcome message which will henceforth be sent to new subscribers. Gentlemen (and ladies, one would hope), start your engines... Welcome to the TAPR Spread Spectrum SIG! This mailing list is for the discussion of topics related to the application of spread spectrum communications technology to amateur packet radio networking. The emphasis of this SIG is on the technology of spread spectrum rather than regulatory or political issues. Suitable topics include: - New SS chipsets and modem products, and their applicability to the amateur service - Performance reports on existing products (e.g., Part 15 WLAN devices) - Relative merits of direct sequence, frequency hopping and hybrid approaches in amateur SS applications - Use of CDMA and other multiple access techniques to build packet radio LANs/MANs - Dealing with shared allocations and interference in the UHF and higher amateur bands - Proposals for development projects in amateur packet SS - Sources of SS information on the Internet and elsewhere: books, articles, web pages, FAQ files, etc The TAPR SS SIG is unmoderated. We would like to keep it that way, to encourage the open exchange of ideas and minimize the turnaround time. This will only be possible if the participants exercise some restraint. Discussions of technical issues can get heated at times, but they are not useful unless they also shed some light on the topic. Personal attacks will not be tolerated, and may result in the offender(s) being summarily removed from the list. Maintainer of the SIG is Barry McLarnon, VE3JF.

The devices have been developed in collaboration with SAIT Systems, a Belgium telecom company, and the European Space Agency. The family of spread spectrum chips currently available aims at niche markets where highly reliable wireless communications are required, such as industrial networks for monitoring and control. The Programmable Mobile Communications Modem (PMCM) is a digital transceiver chip integrating baseband and IF functionality with very low implementation loss. Fully programmable spreader and correlator functions, band-limiting oversampling filters and IF up-and down-converters are on chip. The ASIC can process 10 Mchips/s and incorporates an interface for an external processor for the application-dependent functionality. The PMCM encapsulates a complexity equal to 95,000 gates. The PMCM provides a low cost and highly-miniaturized solution for applications such as VSAT communications and terminals for Private Mobile Radio networks via satellite. Code lengths of up to 1024 are supported. The high processing gain also makes the PMCM a versatile key component for wireless LAN applications where robustness of the link is crucial, such as in industrial environments with high and unpredictable interference levels. The Advanced Spread spectrum Transceiver ASIC (ASTRA) is a high speed, low power version of the PMCM, providing 15 Mchips/s, parallel demodulation of 4 channels and a 32-bit interface to a host processor. The Direct Sequence Integrated Receiver with ARM (TM) Core (DIRAC) chip combines flexible and highly integrated IF receiver chain with an on-chip 32-bit ARM microprocessor core. Cost effective spread spectrum receivers, for satellite services for example, can be built using this device. A spread spectrum development kit built around the PMCM allows users to explore programmable parameter ranges and to determine the parameter set tuned towards a particular application. A rapid design turnaround cycle - in the order of weeks - towards customized components is possible due to the modular architecture of the devices and the advanced CATHEDRAL CAD environment developed at IMEC. Specification, synthesis and simulation at different abstraction levels are all provided in an integrated toolbox. A link with the Synopsys, Inc.'s (Mountain View, CA) design tools ensures compliance with industrial standards of ASIC design. The design path is open to any foundry. A current development is the integration of digital, and analog modem components in an MCM (Multi-Chip Module) package, which enables further reductions in size and cost. The next generation of ASICs will concentrate on high-speed operation for markets such as wireless LAN, wireless multimedia and wireless office products. Pricing and Availability Evaluation ASICs are available within 30 days. Production quantity are available in 90 to 100 days ARO. Pricing is between $110 to $270 US and depends on type and quantity ordered. The development kit is available in Q2 '96 and is priced at $4500 US. About IMEC: IMEC was founded in 1984 and today is the largest independent research and development center of its kind in Europe. IMEC employs over 500 people. Its 36,000 sq. ft. clean room is dedicated to advanced research and development into semiconductor processing technologies. Its nearly $60 million revenue is derived from agreements and contracts with government agencies, aerospace and semiconductor industry companies worldwide.

I built up four Spread Spectrum Modems. They are using an OEM Proxim Module. I picked them up so I can finish my modified X.25 packet driver for unix. I'm designing it for free wireless internet access. Also are there any decent books on Spread Spectrum Technology and Data Pumps? I would like to go with my own Data Pump and Radio. Right now the interface, custom firmware, and Software is my design. Since computers fast compared to standards set a few years ago we have plenty of cpu time left to decompress datapackets. The only data not compressed are certain X.25 commands and the destination addresses.... all other data All other data is compressed with my compression. It opens up some bandwidth. Now I would like to get some range. Are there any high speed switching amplifiers (3ns or so). I am operating in the 902-925Mhz band. I was impressed with the range I could get by decoupling the heck out of my interface and Proxims stuff. I also filtered the heck out of the power supply. I was able to get 5,000ft with a 5/8 wave dipole. I would like to get 10miles if possible.
