WiFi stands for Wireless fidelity, which is wireless communication. WiFi is used in local area networks (LAN).
WiFi transmits the 2.4 GHz and 5 GHz radio frequencies data, which is more secure and bigger than the 3G networks.
WiFi technology is not so expensive.
You can easily install WiFi on any computer or any other electronic device by introducing LAN on any computer with a wireless adapter.
WiFi can also be used to connect gaming consoles, printers, laptops, and other such devices.
WiFi networks have signal reach for about 300+ feet; therefore, they are best for indoor use.
The service provider manages third-generation (3G) services. 3G application is based on the Wide Area Network (WAN). 3G is costly than that of WiFi and is installed only by the transporter companies. 3G Technology is more convenient and has a wider area than WiFi networks. However, you have to pay to connect to the 3G network.
3G is more reliable as compared to WiFi networks. It is because they do not get influenced by power-cuts or bad connections.
Both the technologies have their benefits it all depends upon your requirements whether you want Internet for indoors or outdoors or prefer the one which is less costly and more reliable.
