  4G(LTE)无线安全

  一般而言,石油和天然气业务分布在大的地理区域,集中控制中心的工人管理和运营日常的现场作业,这些作业受到恶劣的环境条件的影响。在“过去”,甚至今天,超高频无线电通过低速串行接口(RS232)无线电信道连接现场DTU,这些无线电信道不超过25kHz,DTU使用这些信号以大约19.6kbps的。这种方法足以提取到现场设备中提取数据,并向管道发送监控控制命令,例如对阀门的关闭/打开命令和对泵的启动/停止命令。只要有用于诊断目的的资产管理解决方案,就需要高速。通常,非关键SCADA监控应用允许无线通信,并且在网络,通信硬件,服务器等方面应该存在与非SCADA应用的物理和逻辑隔离。
