WDM驱动程序设计　　 一．WDM简介 　　微软不断推出新的操作系统，现在Windows98和Windows2000已经成了主流，原先用来实现驱动程序的VxD技术随着Win95的淡出也慢慢地将退出历史舞台，在Windows98和Windows2000中设备驱动程序将根据Windows驱动程序模型（WDM）来设计。WDM通过提供一种灵活的方式来简化驱动程序的开发，在实现对新硬件支持的基础上减少并降低所必须开发的驱动程序的数量和复杂性。 -WDM Driver Design 1. WDM briefed constantly introduce new Microsoft operating system, now Windows 98 and Windows 2000 has become mainstream. originally used to achieve the VxD driver technology with the Windows 95 are slowly fade out to be from the historical stage, in Windows 98 and Windows Device Drivers under Windows Flooding dynamic process model (WDM) to the design. WDM by providing a flexible way to simplify driver development, the realization of new hardware support on the basis of the reduction and cut the need to develop drivers for the number and complexity.

移动电话主要采用频率复用，但分配给移动电话的频段很少，远不能满足用户的需要。 因此就提出将地区划分成小区，称为蜂窝（Cell），每个蜂窝内使用一组频率，相隔一段距离后，相同的频率又可重复使用。 -The main use of mobile phone frequency reuse, but allocated to the small-band mobile phone, far from being able to meet the needs of users. Therefore proposed to be divided into residential areas, known as cellular (Cell), each use a set of cellular frequencies, separated by some distance, the same frequency can be reused.
