WLAN和WWAN之间的区别

1.无线局域网(WLAN) ：
无线局域网(WLAN)是一种无线连接到网络的设备的网络。它通常与WI-FI互换使用，但是Wi-Fi称为特定网络，而WLAN则是整个分发系统本身。但是，它与LAN分配非常相似。两者都使用DHCP为新设备提供动态IP地址。关于WLAN的最好的事情是它没有缠结电缆的麻烦。这允许组织使其成员保持联系，但是范围是有限的。可以在移动或台式设备上访问它。而且，WLAN便宜得多，并且可以升级而不会花费用户很多钱。

WLAN的优势：

• 无线连接
• 可扩展范围
• 信号没有被任何物理障碍物阻挡
• 在小面积覆盖范围内表现良好
• 可靠的通讯

2.无线广域网(WWAN)：
无线广域网(WWAN)是与WIMAX，CDMA，GSM等移动通信技术配合使用的网络连接。任何具有WWAN卡的用户都可以连接到WWAN并访问Internet。它覆盖的区域非常大，可以覆盖区域，全国和全球无线网络，并且由于WWAN使用128位加密，因此也非常安全。此外，WWAN使用更方便且信号问题更少的电信网络。它在全球范围内建立。

WWAN的优势：

• 快速部署
• 一应俱全
• 易于安装
• 减少基础设施
