1.无线局域网(WLAN) ：
无线局域网 (WLAN) 是一种网络，其中连接到网络的设备以无线方式分布。它通常与 WI-FI 互换使用，但 Wi-Fi 被称为特定网络，而 WLAN 是整个分配系统本身。但是，它与 LAN 分布非常相似。两者都使用 DHCP 为新设备提供动态 IP 地址。 WLAN 的最大优点是它没有缠结电缆的麻烦。这允许组织让其成员保持联系，但范围有限。它可以在移动或桌面设备上访问。此外，WLAN 便宜得多，而且无需花费用户一大笔钱就可以升级。
无线局域网的优势：
- 无线连接
- 可扩展范围
- 信号未被任何物理屏障阻挡
- 小面积覆盖性能好
- 可靠的通讯方式
2. 无线广域网(WWAN)：
无线广域网 (WWAN) 是一种与 WIMAX、CDMA、GSM 等移动通信技术配合使用的网络连接。任何拥有 WWAN 卡的用户都可以连接到 WWAN 并访问互联网。它覆盖的区域非常大，覆盖区域、全国和全球无线网络，而且由于 WWAN 使用 128 位加密，因此非常安全。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的优点：
- 快速部署
- 一应俱全
- 易于安装
- 更少的基础设施

| 01. | WLAN is known as Wireless Local Area Network or LAWN (Local Area Wireless Network). | WWAN is known as Wireless Wide Area Network. |
| 02. | WLAN uses radio, infrared, and microwave transmission. | WWAN uses cellular network. |
| 03. | WLAN can cover only a small organization at most. | WWAN has worldwide coverage. |
| 04. | WLAN has excellent speed and performance. | WWAN has very low speed and performance. |
| 05. | It uses WEP or WPA which are less secure. | It uses 128-bit encryption which makes it very secure. |
| 06. | WLAN takes very little time to set up and run. WWAN users have to make a contract with their ISPs. | WWAN users have to make a contract with their ISPs. |
| 07. | WLAN can be used with all devices. | WWAN is limited to mobile devices only. |
| 08. | WLAN upgrade is very cheap. | WWAN upgrades cost higher comparatively. |
