REDWINGCDPD Airlink CDPD Cellular Digital Modem

Overview

The RedwingCDPD supported telecommunications between a datalogger and a cellular digital packet data (CDPD) network. This CDPD modem was IP based; the cellular provider needed to assign an IP address for the site. The Redwing had many of the same features as its predecessor, the Raven II.

The RedwingCDPD modem was retired 11 March 2004 because of the discontinuation of CDPD services.
