Data is transmitted in the 2.4 GHz (gigahertz), which is license-free worldwide, with a data transfer rate of up to one megabit per second.
The transmission power of the Bluetooth headset interface is like watts. This provides a transmission range of about ten meters, more than enough to interconnect the individual devices inside a vehicle in the future. The low transmission power also serves to increase the security of the data, because it not only prevents the interception of data, it is also immune to interference from electromagnetic radiation sources. As additional protection against interception of data transmissions, a profile is assigned to each Bluetooth device.
Index and more
This profile comprises a unique index number that allows devices which are intended to communicate with each other to identify themselves. The encryption with a 128-bit code randomly generated for each new communication process provides a degree of protection to transmit data.
Bluetooth headset Technology
Bluetooth headset technology advances, there is a very practical. This technology has also been imposed on mobile phones to share information quickly and securely.
So far, criticizing this service is its power consumption on the devices that use it. Thus it has been working to ensure that Bluetooth 4.0 will resolve this problem. On December 17, the SIG released a press release informing the Bluetooth Core Specification adopt 4.0 as new technology to be used in future wireless devices.
Even before the release of Bluetooth 3.0 are already making plans for the launch of this new technology that will revolutionize the use of small mobile devices.
Bluetooth headset specifications
This opens the door to cover a larger market of devices, especially now used to power those computers that provide low levels of energy, such as those using the button batteries (the type DC1020). Current devices can seamlessly use the new Bluetooth 4.0 technology, noting an improvement in the delivery of the same.
Bluetooth headset Core Specification 4.0 will provide a greater range (over 100 meters), protecting the data under a 128-bit encryption (tightening security at maximum), and reaching speeds up to 1 megabit per second. Work within the ISM 2.4 GHz band.
This development may be used in fields that for now have not been possible for energy problems. So we'll see this technology appear in the areas of health and safety as it can be used in smaller devices. And improve in the areas of entertainment and sports. There is not much info on how the best brands will handle the marketing strategy to take advantage of the sale of Bluetooth headset technology 3.0 and then impose the 4.0, without that retains users from buying the previous version.
