Bluetooth, such presence has become imperative in a phone. Well, now there is a Bluetooth version. What advantages?From day to day, the Bluetooth Special Interest Group (SIG) 'dig' continues to develop Bluetooth technology. Bluetooth Special Interest Group (SIG) is an alliance of several telecommunications companies, computing, consumer electronics, automotive technology, which develops Bluetooth devices to be immersed in the market to absorb.Understandably, 'the blue tooth' has become a popular fruit facility by mobile users. The reason is very easy to use. Moreover, now has more flexibility to recognize the device with other Bluetooth facilities.Now entering 2010, the Bluetooth SIG introduced the latest version of Bluetooth 4.0. Bluetooth technology, this one prioritizes the use of energy-efficient wireless technology, as he often sounded lately.With the advantages, it is expected that this new Bluetooth is more interested in producing electronic and more easily absorbed by the market. In addition to the industry as we know, some other industry that is estimated to take advantage of this energy saving technology is the health industry, sports and fitness, security and household entertainment.Nokia is already committed to using energy-efficient wireless technology since the Wibree technology is also enthusiastically received. It is expected that this technology could open more market opportunities in the related industry.Based on the information in http://www.bluetooth.com, some advantages of Bluetooth 4.0:
- Power consumption is smaller, so saving battery or electricity.
- Time using a longer until the annual by using only a small capacity batteries (coin-cell batteries)
- Low production costs
- Longer distances because it can reach more than 100 m.
- Better transfer speeds. With the ability to approximately 1 Mbps.
- Security system was much better.
Data Transfers - Bluetooth technology Low energy supports data packet is very short. Minimum of 8 octets and the maximum reach of 27 octets transmitted at speeds of 1 Mbps.Frequency Hopping - Low energy Bluetooth technology uses frequency hopping modulation is adaptive to all versions of Bluetooth technology. The goal is to minimize interference with all the technology that works on 2.4 GHz ISM frequency band. Efficiency of multi-path takes advantage of the increase in link budgets.Host Control - low energy Bluetooth technology to place a significant number of controllers. So the host can have more time to sleep period. And work when needed only. This will provide significant savings for the host is assumed to use high power consumption compared to the controller.Latency - Low energy Bluetooth technology can support the connection setup and data transfer up to 3ms. Very short so that when needed, you can quickly decided to return the connection after the transfer process.Range - Improved modulation index range for Bluetooth provides low-energy up to 100 meters.Robustness - Low energy Bluetooth technology uses 24-bit CRC on all packages to ensure the power of this technology to the possibility of interference.Strong security - Using AES encryption Full-CCM 128, which is strong encryption of data packets.Topology - Low energy Bluetooth technology uses 32-bit access address on each packet for each slave. Thus, billions of devices can be connected. This technology is optimized using the connection one-to-one. Connections and also supports one-to-many using a star topology. When you use the quick connections or disconnections, data can be moved such premises mesh topology.
