What are the differences between bluetooth and Wi-Fi?

They share the same 2.4GHz frequency band, but have very different applications.

Bluetooth is designed to inexpensively connect things like keyboards, mice, headsets and printers to computers, PDAs, and cell phones, and therefore does not need broadband capability. Bluetooth does not require a router, relying on device-to-device connections, and supporting a maximum of 8 devices.

Bluetooth is a personal area networking technology, operating generally within one room only, and at lower speeds than Wi-Fi -- 771Kbps for Bluetooth 1.x and 2.1Mbps for Bluetooth 2.0.
