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
WLAN和WWAN之间的区别:
