Definition | WiFi stands for Wireless Fidelity. Wi-Fi is a technology that enables devices to connect to the Internet wirelessly. | Bluetooth is a wireless technology that is used to connect devices in short range. |
Component | WiFi requires wireless adaptor on all devices and Wireless Router for connectivity. | Bluetooth requires an Bluetooth adaptor on all devices for connectivity. |
Power Consumption | WiFi consumes high power. | Bluetooth is easier to use and consumes less power than Wi-Fi because it only requires an adapter on each connecting device. |
Security | WiFi is more secure than Bluetooth. | Bluetooth is less secure than other wireless technologies such as WiFi. |
Number of Users | Wi-Fi allows more devices and users to communicate at the same time. | Bluetooth restricts the number of devices that can connect at any given moment. |
Bandwidth | WiFi needs high bandwidth. | Bluetooth has a low bandwidth. |
Coverage | WiFi coverage area is up to 32 meters. | Bluetooth coverage area is about 10 meters. |
