无线分组数据网CDPD的网络体系研究

The Research on the Network System of CDPD Mobile Packet Data Network

蜂窝数字分组数据（CDPD）网是一种移动分组数据技术，具有较低的建网、运营成本和业务费用，因此具有广泛推广的价值。详细介绍了CDPD网与空中接口有关的协议分层，各层的实现过程，以及各层之间的相互关系，重点说明了MAC层的具体实现细节，前向信道和反向信道的配置以及数据复用过程等。

Cellular Digital Packet Data (CDPD) network is one of the mobile packet data technologies, with rather lower cost of network laying, operation and lower service fees and worthy of popularization. This paper makes detailed introduction of protocol layers for CDPD network, which is related to air interface, the realization of these layers, the relationship between these layers and so on. We emphasize on the detailed implementation of Media Access Control layer, the configuration of the forward and reverse channel and data multiplexing, etc.
