  • AirLink CDPD Cellular Digital Packet Data About the Technology CDPD is particularly well-suited to mobile professionals because it offers a high-speed, high-capacity, low-cost system with the greatest possible coverage.
  • . Additionally, data is encrypted for greater security.
  • . CDPD became a networking standard in the early 1990s, when a consortium of cellular carriers across the United States came together for the purpose of creating a method for sending data over cellular telephone channels.
  • . They wanted to provide a cost-effective, reliable and flexible solution to providing two-way wireless data communications service for mobile professionals.
  • . CDPD technology is able to detect and use these otherwise wasted moments by packaging data in small packets and sending it in short "bursts" during the idle time.
  • . As a result, the cellular channel operates more efficiently, and voice and data transmissions are unaffected.
  • . AirLink CDPD Raven The Raven is a rugged, full duplex Cellular Digital Packet Data (CDPD) modem that provides wireless transport capabilities for fixed and mobile applications.

  • CDPD: Cellular Digital Packet Data BUS552E EMERGING TECHNOLOGY SCAN Chris Cole Jerry deCesare Joe Ford Michelle Fruman Ned Montag Kevin Mulcrone INTRODUCTION In today's fast paced, highly mobile and time poor society, few business people would argue with the notion that communications, in all its forms, is essential to being a productive, competitive, company of the nineties.
  • . Wireless "data" communications will soon be just as commonplace as the currently popular office and desk top applications are replaced by a mobile professional with a portable and (various) hand held devices.
  • . To facilitate this evolution: Advanced mobile data technology is being deployed by cellular service providers, thereby making the service more reliable, useful and cost effective, and Business benefits are being identified and cost justified by early adopters across numerous market segments.
  • . The following sections of this paper will focus on exploring the Cellular Digital Packet Data technology which is just one option for achieving mobility with respect to data transmissions.
