`
`Over the past few years, Bluetooth has become the wireless data transfer technology of
`choice for most manufacturers of handheld devices because, among other reasons, it
`provides relatively fast transfer speeds, a relatively large range (around 10 meters) as well
`as a very high level of versatility, since Bluetooth chipsets can be installed in a wide variety
`of portable devices. And now, the Bluetooth Special Interest Group, the organization in
`charge of advancing Bluetooth technology, has the unanimous decision of adopting the
`Core specification, namely Version 2.1 +EDR, which will bring about some very important
`changes in both device manufacturing technologies and the level of performance
`provided by Bluetooth wireless connections.
`
`The new Core Specification Version 2.1 +EDR provides several important developments
`over the past versions. Thus, first of all, it offers improved pairing capabilities, namely a
`consistent and intuitive pairing solution that includes finding devices, securing the link and
`authenticating the devices. Moreover, for those pairing scenarios that require user
`interaction, eavesdropper protection makes a simple six digit passkey stronger than a 16
`digit alphanumeric character random PIN code. The improved pairing feature also offers
`"Man in the Middle" protection that eliminates the possibility for an undetected middle
`man intercepting information.
`
`The new Bluetooth version also optimizes the level of power consumption through a
`feature called Sniff Subrating, which increases current battery life by up to five times in
`many devices like mice, keyboards, watches, home sensor networks and medical devices.
`Moreover, the 2.1 + EDR provides the required support for NFC technology (Near Field
`Communication), which allows a user to hold two devices together at a very short range in
`order to start the quick pairing process.
`
`"The simplified pairing process enabled by Version 2.1 +EDR has received overwhelmingly
`positive feedback from media, analysts and member companies. This leap forward in
`usability further improves the Bluetooth experience and makes the technology easy for
`anyone to enjoy," said Michael Foley, Ph.D., executive director of the Bluetooth SIG. "Also,
`in our effort to unite wireless technologies, Version 2.1 + EDR enables the ultra short range
`technology called Near Field Communication (NFC) for a pairing scenario that is as simple
`as touching the products together."
`
`Since version 2.1 + EDR has been in the works for quite some time now, most chipset
`manufacturers have already implemented its features in their future products. Thus,
`according to the Bluetooth SIG, the first devices complying with the new core version will
`hit the market towards the end of 2007, thus marking a whole new evolutionary for this
