HC110116004 企業(yè)無線解決方案

企業(yè)無線解決方案Page2前言

一般地，企業(yè)網(wǎng)絡(luò)與Internet的連接都是有線連接；為了增強(qiáng)企業(yè)網(wǎng)絡(luò)與Internet連接的可靠性，我們還可以通過WWAN增加企業(yè)網(wǎng)絡(luò)與Internet的無線連接。這樣，當(dāng)發(fā)生不可預(yù)見的故障而導(dǎo)致企業(yè)網(wǎng)絡(luò)與Internet的有線連接中斷時，無線連接就可以接管故障，保證企業(yè)網(wǎng)絡(luò)與Internet的連通性，進(jìn)而保障企業(yè)網(wǎng)絡(luò)業(yè)務(wù)的連續(xù)性和可用性。Page3學(xué)習(xí)目標(biāo)
