最先进的计算机网络形式是广域网 (WAN) 和无线广域网 (WWAN) 。
广域网和无线广域网是相互关联的，而且具有相同的特征。广域网是一种计算机网络形式，已在世界上的多个地区使用。而无线广域网是一种起源于最近的计算机网络，现在被全球许多人广泛使用。
让我们讨论一下广域网和无线广域网。
| WAN | WWAN |
|---|---|
| WAN stands for Wide Area Network | WWAN stands for Wireless Wide Area Network |
| WAN connections can include wired and wireless technologies | WWAN connections are completely wireless |
| WAN covers a wide geographical area | WWAN also covers a wide geographical area |
| In WAN, Wired systems are less expensive, faster, and more secure than wireless networks. | As WWAN has only wireless connection, it’s reliably expensive than WAN connections. Also Wireless connections are also considered to be non-secure |
| The network speed and the speed of which data are transported, is comparatively slower for a WAN than for a WWAN. | The network speed and the speed of which data are transported, is faster for a WWAN than for a WAN |
| WAN provides good performance when it’s been wired and comparatively lower performance than WWAN when acting as wireless | WWAN ensures perfectly good performance until interrupted by any external agents like poor climate etc.. |
| The cost of installation is less and setting the connection is moderately difficult | The cost of installation is more and setting the connection is easier |
| Mobility limited | Outstanding Mobility |
| connections cannot be interrupted easily | chances of connection interruption is high |
