Alternatives to Bluetooth

Application: Bluetooth and Wi-Fi are both wireless networking standards that provide connectivity via radio waves. The main difference: Bluetooth's primary use is to replace cables, while Wi-Fi is largely used to provide wireless, high-speed access to the Internet or a local area network.

Security: Bluetooth is a bit more secure than WiFi. For one thing, Bluetooth is designed to cover shorter distances than 802.11b, Also, Bluetooth offers two levels of password protection. Wi-Fi has all the security risks associated with other networks: Once someone has access to one part, he or she can access the rest.

Ease of use: Bluetooth devices advertise their capabilities to others, and a single device can be connected to up to seven other devices at the same time. This makes it easy to find and connect to the device you are looking for or to switch between devices, such as two printers. Wi-Fi is more complex; it requires the same degree of network management as any comparable wired network.

Power: Bluetooth has a smaller power requirement than WiFi, and devices can be physically smaller, making it a good choice for consumer electronics devices.
