Software helps Bluetooth run over UWB
radio
The Bluetooth Special Interest Group has demonstrated Bluetooth applications running over ultrawideband radios using Bluetusk technology.
The Bluetooth Special Interest Group (SIG) has demonstrated Bluetooth applications running over ultrawideband (UWB) radios at the Bluetooth SIG All Hands Meeting in Seattle The demonstration used Open Interface North America's Bluetusk technology to stream high definition (HD) video streaming using the Bluetooth Video Distribution Profile (VDP) over UWB radios from Alereon and the Bluetooth Object Push Profile (OPP) over standard Bluetooth Version 2.0

Bluetooth software works on UWB hardware
Open Interface North America has demonstrated its Bluetusk software operating with Freescale Semiconductor's ultrawideband hardware at the Wireless Connectivity Americas conference.
Programme smoothes way to Bluetooth integration
Open Interface has devised the Bluemagic Solutions Programme to coincide with the launch of version 3.0.10 of its Bluemagic 3.0 embedded Bluetooth software.
The demonstration, presented during the keynote address by Michael Foley PhD, Executive Director of the Bluetooth SIG, highlights the Bluetooth SIG's commitment to evolving Bluetooth wireless technology to leverage the higher datarates achievable with UWB and other alternative MAC/PHY technologies.
"Bluetooth technology has two core strengths that are missing in other short range radio standards: specifications for application interoperability in the form of Bluetooth profiles, and the device and service discovery functions needed for secure easy-to-use ad-hoc networking", said Greg Burns, CTO of Open Interface North America.
"Combining these core strengths with the high bandwidth of UWB radios makes applications such as HD video streaming possible and existing Bluetooth applications such as file and image transfer, printing, and synchronisation work better".

Modules cut the cost of Bluetooth audio
Open Interface's market leading Soundabout solution is now available as a complete hardware solution.
The demonstration showed existing Bluetooth applications running unmodified over UWB.
The hardware setup featured three laptops and a mobile phone; all devices have Bluetooth radios and an alternative MAC/PHY radio and form a single piconet.
One laptop was running the Bluetooth VDP sink and was connected to a large screen display, another laptop was running a Bluetooth FTP, the third was the piconet master and was running the Bluetooth VDP source, FTP client and an OPP server.
The master connected to the two other laptops and during the negotiation of the connection discovered that these laptops supported an alternative MAC/PHY.
Open Interface's Bluetusk technology was employed to establish datalinks using the higher speed MAC/PHY connections and reroute the Bluetooth data over these links.
Except for the greatly increased datarates, the applications were completely unaware that the data were being rerouted.
In the demonstration scenario, after the datalinks were established, the Bluetooth video distribution profile was used to transmit an HD video stream to the laptop with the large screen display.
Meanwhile, a file was transferred to the other laptop.
To demonstrate that full Bluetooth interoperability was maintained while video was being streamed and files were being transferred, a picture was pushed from a mobile phone using OPP.
