Mr kruck says he knows of three us companies that have recently suffered serious attacks on wireless networks from dissgruntled emplyees or exempllyees 克鲁克说，有3家美国公司的无线网最近遭到了不满情绪的雇员或前雇员的严重攻击。
At present , most of monitoring system is constituted by special transmitting systems such as fiber , radio net and special control computers 目前，监测系统多采用专用信道(如光纤、无线网等)以及专用的工业控制微机完成这一任务，成本高。
Hotspots aren ' t limited to public areas like coffee shops and subway stations . many commercial buildings have also set up wireless networks for employees 无线上网据点并不限于咖啡厅或地铁站等公共场合。许多商业大楼也为员工架设无线网路。
Emergency communication system is outlined firstly , including network stfucture , prn system , low - layer protocols and frame format 本文首先介绍了应急机动部队综合通信系统概况，包括网络结构、分组无线网体制、低层通信协议以及分组格式。
The master communicates with the relay unit by serial communication interface and the relay unit communicates with module unit by wireless communication network 上位机和中继单元之间采用串行口通信,中继单元和模块单元之间采用无线网路进行通信。
At the beginning of the paper , the author introduced general situation of the prnet including the topological structure , main characteristics and key technologies 然后，研究了分组无线网中的介质访问控制( mac ， mediaaccesscontrol )的技术问题。
Cognitive radio technology , in contrast , embeds the intelligence required to connect to wireless networks in the radio handset , laptop or wireless organizer 相反的，感知无线电技术则将连接无线网路需要的资料直接放在无线电手机、笔记型电脑或无线设备中。
