. The Ricochet Wireless Network Overview <br />Page 3 of 5 <br />modem is powered on. Ricochet modems used in peer -to -peer mode do not require Name <br />Server validation. <br />The Ricochet Wireless Modem <br />The Ricochet modem weighs 13 ounces, about the size of a television remote <br />control, and plugs directly into a desktop, laptop or PDA standard serial port. <br />Subscribers to the Ricochet service can make modem connections anywhere <br />within a coverage area. Ricochet modems can also communicate with other <br />Ricochet modems on a peer -to -peer basis outside the service area. <br />The modem is compatible with both Macintosh and Intel -based hardware platforms; <br />Macintosh, Windows 3.1 and Windows 95 operating systems; and most communications <br />software - eliminating the need for additional middleware. <br />For more information check the Ricochet Home Page. <br />Glossary <br />Frequency -hopping <br />his relates to the technology used when moving RF data <br />packets from one frequency to another. <br />Intranet <br />The Intranet is a company's internal on-line site, often protected <br />y firewalls if connected to the Internet. Intranet users must <br />have special authorization in order to access private and <br />sensitive information and data bases. <br />IP <br />kbps <br />Internet Protocol consists of procedures and rules for <br />mmunicatin over the Internet. <br />ilobits per second indicates the rate of speed data is being <br />ransferred (corresponding to 1,024 bits per second). <br />LAN <br />Local Area Network is a communications arrangement that <br />nnects multiple computer and related products in an office, <br />uilding or campus environment by means of a standard <br />ransmission medium (e.g., coaxial cable, twisted -pair wire or <br />tical fiber). <br />CDN* <br />11networking <br />The MicroCellular Digital Network is foundation of the wireless <br />architecture Ricochet uses. It is is comprised of four primary <br />technology elements: the 902-928 MHz frequency band, <br />spread-spectrum/frequency-hopping, packet -switched <br />and protocols for transmitting and receiving data. <br />Microcell Radio* <br />[so known as Radio Transceivers, Microcell Radios are shoe- <br />ox sized repeaters designed to receved RF packets from <br />icochet modems or other Microcell Radios. They are generally <br />eployed in clusters from one-half to two miles apart in a mesh <br />opology. <br />Modem Radio* <br />slbscriber device that connects to most desktop, laptop or <br />acomputing devices through a serial port.
