CDPD Mobile Data Base Station (MDBS)

Contributed by Yi-Bing Lin

The MDBS is responsible for detailed control of the radio interface, such as radio channel allocation, interoperation with cellular voice channel usage and radio media access control.

A MDBS consists of several modem-transceivers each of them supports one CDPD channel pair. The user data received by the modem-transceivers are processed by the control computers before being delivered to the MDIS.
