Method and system for utilizing a 60 GHZ PHY layer for high speed data transmission between bluetooth devices

Abstract: Wireless devices may utilize a Bluetooth stack to setup a data transmission session between the devices The data transmission session may comprise a Bluetooth PHY and/or MAC/PHY layer that enables the wireless devices to perform discovery, pairing, and security setup operations A secondary physical layer may be utilized to perform high speed data transmission The secondary physical layer may comprise a 60 GHz PHY and/or MAC/PHY The secondary physical layer may be integrated via the Bluetooth stack, and applications running on top of the Bluetooth stack may utilize the secondary physical layer transparently A portion of the transmitted data may be multiplexed onto other secondary physical layers that may be available in the wireless devices Alternatively, transmission of data may comprise switching among available secondary physical layers The Bluetooth PHY and/or MAC/PHY layer may be utilized during data transmission to continually monitor and/or manage the data transmission

Apparatus and method for connecting between bluetooth devices

Abstract: An apparatus and a method for connecting Bluetooth devices are provided to improve a user convenience and a connection speed, and be applied to a Bluetooth stack without making a big correction to the stack Bluetooth controllers(34,44) convert a command and data into a Bluetooth packet or perform the reverse operation RF units(35,45) convert a packet applied from the Bluetooth controllers into an RF signal and transmit it, or receive an RF signal, convert it into baseband data, and apply it to the Bluetooth controllers Socket units connect two Bluetooth devices(30,40) and inform about a connection recognition signal and their polarity Controllers(32,42) recognize connected Bluetooth devices upon receiving the connection recognition signal through the socket units, check whether they are a master upon recognizing their polarity, and automatically search the mutually other Bluetooth device and perform pairing

Bluetooth stack processor with QOS

Abstract: A baseband processor (20) for a Bluetooth device (80) processes packets according to a protocol stack, and uses a Bluetooth host controller interface (30) to receive packets having given priorities, from a higher protocol level or levels. Packet buffers (B1-Bn) are used to buffer the received packets, and the processor reorders the buffered packets according to their priorities, to output a prioritized stream of packets suitable for transmission by a radio part. By prioritising after the HCI interface, rather than before it, the QOS queues can be effectively located at a lower level in the stack. This means the decision made about the order of transmission of the packets, can take place later, meaning a higher probability that a high priority packet can "pass" queues of lower priority packets, and reach the air interface sooner. The reordering can involve a multiplexer (200) arranged to multiplex packets from multiplee packet buffers according to their priorities.
