蜂窝网络：
蜂窝网络由一些小区组成，小区覆盖一个地理区域，有一个类似于802.11 AP的基站，帮助移动用户接入网络，移动和基站之间有物理层和链路层协议的空中接口。所有这些基站都连接到移动交换中心，该中心将小区连接到广域网，管理呼叫建立并处理移动性。
无线上网：
它代表无线保真。它是一种与基于 IEEE 802.11 标准的设备进行无线局域网联网的技术。 Wi-Fi 兼容设备可以通过 WLAN 网络和缩写为 AP 的无线接入点连接到互联网。每个 WLAN 都有一个接入点，负责从/向用户接收和传输数据。
蜂窝网络和 Wi-Fi 网络之间的区别：
| S.NO. | CELLULAR | WI-FI |
|---|---|---|
| 1 | Cellular plan are attached to the device that uses cellular signal to connect to the internet. | Wi-Fi is a local area networking technology that uses radio waves to provide high-speed internet access to mobile devices enabled with Wi-Fi. |
| 2 | Cellular refers to a mobile network which is distributed over a wide area. | Wi-Fi is a critical element and a crucial wireless networking technology based on the IEEE 802.11 standards. |
| 3 | Cellular has no limit in the range. | Wi-Fi has a limited range. |
| 4 | Mobile technology is the technology used for cellular communication. | Device can use the Wi-Fi standard to broadcast and receive information. |
| 5 | Cellular has a data plans with limited consumption. | Wi-Fi has no limit on how much data you can use in a day or a month. |
| 6 | Cellular network are relatively slow in terms of speend and reliability. | Wi-Fi are faster than Cellular Network.. |
