BROWNRIGG explained that the frequencies at which the radios would run are very short wave signals. They are well above standard microwave and radar. With a radio wave that small, one watt becomes a tremendous punch per bit and thus makes transmission at reasonable speed possible. In order to minimize the potential for congestion, the project is undertaking to reimplement software which has been available in the networking business and is taken for granted now, for example, TCP/IP, routing algorithms, bridges, and gateways. In addition, the project plans to take the WAIS server software in the public domain and reimplement it so that one can have a WAIS server on a Mac instead of a Unix machine. The Memex Research Institute believes that libraries, in particular, will want to use the WAIS servers with packet radio. This project, which has a team of about twelve people, will run through 1993 and will include the 100 libraries already mentioned as well as other professionals such as those in the medical profession, engineering, and law. Thus, the need is to create an infrastructure of radios that do not move around, which, BROWNRIGG hopes, will solve a problem not only for libraries but for individuals who, by and large today, do not have access to the Internet from their homes and offices. ****** +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ DISCUSSION * Project operating frequencies * +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ During a brief discussion period, which also concluded the day's proceedings, BROWNRIGG stated that the project was operating in four frequencies. The slow speed is operating at 435 megahertz, and it would later go up to 920 megahertz. With the high-speed frequency, the one-megabyte radios will run at 2.4 gigabits, and 1.5 will run at 5.7. At 5.7, rain can be a factor, but it would have to be tropical rain, unlike what falls in most parts of the United States. ****** SESSION IV.
