Bluetooth Low Energy Technology

Bluetooth low energy is a key feature of Bluetooth v4.0 and will redefine the methods of Bluetooth technology again. Bluetooth low energy continues the "traditional" spirit of Bluetooth technology, including ad hoc connectivity, high on-line performance and high interactivity, and fortifies the innovative and ultra low power mode, and provides a new variety of cases and application.

The crux of Bluetooth low energy is aimed at carrying out the optimum design for transmission of a little amount of information and maintains delay at a minimum. Compared to the traditional 100ms, the transfer time for the whole data of Bluetooth low energy is less than 6ms. The characteristic makes the Bluetooth device well establish online and transmit data before fast decatenating. The similarity with the traditional Bluetooth technology lies in that Bluetooth low energy use fast frequency hopping to decrease interference from other technologies at the minimum. Therefore it is very suitable for home environment containing a plurality of equipment with different communication protocols. For example, Wi-Fi, in a confined space, are all using the same 2.4GHz spectrum. Furthermore, the adaptive hopping technology and temporarily coexistence technology make Bluetooth low energy technology be put in a fully functional but compact device with Wi-Fi RF together. Bluetooth technology has been developed for 10 years. The good experience can make the professionals take an impact on Bluetooth low energy and assist it to find the localization in wide applications.

Coexistence technology and ultra low power consumption make Bluetooth become the most ideal wireless technology with simple devices. From the remote control to a heart monitor, these are applications without frequent replacement for battery. From the basic remote control with a long battery life to the high-end remote control with keyboard for Internet televisions, Bluetooth low energy technology provides an effective solution. This predicts that the future mobile phones, netbooks and tablet computers can be implemented to control the applications of all home audio-visual equipments.
