What is Bluetooth and how does it compare to WiFi?
Bluetooth (BT) is a separate set of wireless standards to the IEEE 802.11 suite. It is similar to WiFi in that it can connect two devices with radio signals. The differences: Speed: BT speeds are ~ 720kbps, WiFi maxes out at 11mbps Distance: BT primarily was designed for short range, up to 30 feet; while WiFi theoretically can reach 500 feet. Applications: BT was designed as a cable replacement, essentially to connect devices point-to-point. WiFi is designed to hook up an entire network. Simplicity: BT devices “advertise” their capabilities to others, and a single device can be connected to up to seven other devices at the same time. Cost: A quick survey of prices indicates that BT devices are slightly more expensive than their WiFi counterparts. However, the total final cost for each individual user will depend largely on their intended usage. Those people that already have some BT devices (BT-enabled printers and cell phones, for example) will find it less expensive to add a BT CF ca
