BLUETOOTH

Bluetooth technology is accepted world wide, and has been implemented as a standard having been adopted by more than 2,000 manufacturers.

PROS:
- You can use Bluetooth on laptops, mobile phones, music players, headsets, printers and a host of other products.
- Bluetooth technology is cheap to implement for the companies resulting in lower costs to the consumer. The technology itself is license free, and so does not cost a penny in data charges.
- Unlike infrared, Bluetooth isn't a line of sight technology (so is not affected by obstacles), and it comes with ranges of up to 100 metres (for class 1 devices).

CONTRAS:

-When using Bluetooth Internet, the connection can sometimes run very slow.

- Infrared technology can have data rates of about 4 MBps, which delivers very fast rates for data transfer, whilst Bluetooth only has up to 2.1 MBps.

- Battery use - although Bluetooth has a low power consumption, using this technology will use up more battery power if left on; a concern in devices such as mobile phones.
