15.5 Evolution of Bluetooth


The interesting aspect of Bluetooth technology is that it has attracted manufacturers from varied industries, including automobiles, computing, communications, digital photography, and handheld devices. Currently there are numerous manufacturers developing Bluetooth products such as PC cards and adapters for use in laptops, PDAs, and in PCs. The next step would be to integrate Bluetooth into mobile phones, PDAs, laptops, headphones, and home gateways connected to the Internet. The usability is further extended in automobiles and appliances.

On the technology front, Bluetooth SIG continues its specifications development in enhancing the technology and its usage scenarios. In future releases, the SIG is planning to include a specification for higher data rates (between 2 and 10 Mbps) to support multimedia applications that require higher bandwidth. At the time of this writing, the SIG has announced two new wireless advancements from their working groups that address the needs of mobile phone users. The Car working group within SIG has announced that the new hands-free profile will enable hands-free use of mobile phones in automobiles. Second, the Imaging working group announced the introduction of the new Imaging profile for use in wirelessly transmitting digital images.

In addition, a printing profile is being specified to allow devices to issue wireless print commands to the Bluetooth-enabled printer. Recently, a new profile called the Bluetooth Extended Service Discovery Profile (ESDP) for Universal Plug and Play ¢ (UPnP ¢ ) was introduced that defines how devices with Bluetooth can use the Service Discovery Protocol initially to discover other devices that support UPnP services and retrieve information about these services.

With current capabilities and future technology developments, Bluetooth technology will become more ubiquitous than it is today.
