Over long distances,the options for transmission technologies dwindle,leaving 4G/5G cellular,LPWAN,and satellite as suitable,reliable options for remote connectivity.
在长距离传输中,传输技术的选择越来越少,使得4G/5G蜂窝、LPWAN和卫星成为远程连接的合适、可靠选择。
“The trade-offs between 4G cellular,LPWAN,and satellite have long been known,”said lead analyst and report author Michael Sullivan.“LPWAN’s low bandwidth is well-suited for remote device monitoring,while satellite’s long range makes it suitable for environmental monitoring.”
首席分析师兼报告作者Michael Sullivan表示:“4G蜂窝、LPWAN和卫星之间的权衡早已为人所知。LPWAN的低带宽非常适合远程设备监控,而卫星的长距离使其适合环境监控。”
