What is AirPort? What is AirPort Extreme?
AirPort (802.11) provides a maximum wireless data rate of 11 megabits per second, and AirPort Extreme (802.11g) provides a maximum wireless data rate of 54 megabits per second, which is five times faster.
AirPort Extreme is backwards-compatible with AirPort, and works in much the same way. However, it is worth noting that at 54 megabits per second, the "Base Station range" is only 50 feet, whereas the range is 150 feet at 11 megabits per second.

What is Bluetooth? How much faster is Bluetooth 2.0+EDR?
Apple reports that Bluetooth is:
A cutting-edge open specification that enables short-range wireless connections between desktop and notebook computers, personal digital assistants, mobile phones, camera phones, printers, digital cameras, keyboards and even a computer mouse. Bluetooth wireless technology uses a globally available frequency band (2.4GHz) for worldwide compatibility.
In a nutshell, Bluetooth technology unplugs your digital peripherals and makes cable clutter a thing of the past. . . You can link your Palm OS-based handheld device, mobile phone and other peripherals with Bluetooth technology -- and do it wirelessly, within a 30-foot range.
Bluetooth 2.0+EDR (Enhanced Data Rate), is three times faster than earlier versions.
