摘要
现有视频会议的连接方式分为行业专网和卫星网两种方式,如果视频会议实现4G接入,可以为现有系统又增加一条链路,还能实现多种应用。本文主要对4G技术进行简要阐述,并对其在视频会议中的应用进行探讨。实践证明,4G接入在视频会议中的应用达到良好效果,能在地震应急中发挥重要作用。
Trade special network and satellite network are two connection modes of existing video conference system.If video conference system can realize 4G access,it not only increases a link,but also realizes many applications.This paper expounds the 4G technology,and the application in video conference system.The practice has proved that 4G gets good effect in video conference system can play an important role in earthquake emergency.
