EXTERNAL USB BLUETOOTH ADAPTER

Bluetooth is a technology that lets your computer, monitor, mouse, keyboard, mobile phone - in fact anything which is Bluetooth enabled communicate wirelessly instead of using cables. Other devices which can connect via BlueTooth inlcude Sony Playstation 3, Nintendo Wii, Headphones, Digital Cameras etc.

Some of our Laptops do not come with the option to have an Internal Bluetooth Module, so we now offer an external Bluetooth Adapter which fits straight into a USB Port! A benefit of this is that you can remove the device and use it in pretty much any other PC or Laptop should you need to.

EXTERNAL USB INFRARED ADAPTER

Infrared data transmission is used for in short-range communication among computer peripherals and personal digital assistants. These devices usually meet standards published by IrDA, (Infrared Data Association).

Remote controls and IrDA devices use infrared light-emitting diodes (LEDs) to emit infrared radiation which is focused by a plastic lens into a narrow beam. The beam is modulated, i.e. switched on and off, to encode the data. The receiver uses a silicon photodiode to convert the infrared radiation to an electric current. It responds only to the rapidly pulsing signal created by the transmitter, and filters out slowly changing infrared radiation from ambient light.

Infrared communications are useful for indoor use in areas of high population density. IR does not penetrate walls and so does not interfere with other devices in adjoining rooms.
