| The next version of Bluetooth, currently code named Lisbon, includes a number of features to increase security, useability and value of Bluetooth. The following features are defined:
Atomic Encryption Change - Allows encrypted links to change their encryption keys periodically, increasing security, and also allowing role switches on an encrypted link.
Extended Inquiry Response - provides more information during the inquiry procedure to allow better filtering of devices before connection. This information includes the name of the device, and a list of services, with other information.
Sniff Subrating - Reducing the power consumption when devices are in the sniff low power mode, especially on links with asymmetric data flows. Human interface devices (HID) are expected to benefit the most with mice and keyboards increasing the battery life from 3 to 10 times those currently used.
QoS Improvements - These will enable audio and video data to be transmitted at a higher quality, especially when best effort traffic is being transmitted in the same piconet.
Simple Pairing - this improvement will radically improve the pairing experience for Bluetooth devices, while at the same time increasing the use and strength of security. It is expected that this feature will significantly increase the use of Bluetooth.
The version of Bluetooth after Lisbon, code-named Seattle, has many of the same features, but is most notable for plans to adopt ultra wideband radio technology. This will allow Bluetooth use over UWB radio, enabling very fast data transfers, synchronizations and file pushes, while building on the very low power idle modes of Bluetooth. The combination of a radio using little power when no data is transmitted, and a high data rate radio used to transmit bulk data, could be the start of software radios. Bluetooth, given its worldwide regulatory approval, low power operation, and robust data transmission capabilities, provides an excellent signalling channel to enable the soft radio concept.
