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.

Abstract: Improved apparatus for a radio communication system having a multiplicity of mobile transceiver units selectively in communication with a plurality of base transceiver units which, in turn, communicate with one or more host computers for storage and manipulation of data collected by bar code scanners or other collection means associated with the mobile transceiver units. A network controller and an adapter which has a simulcast and sequential mode provide selective interface between host computers and base transceivers. A scheme for routing data through the communication system is also disclosed wherein the intermediate base stations are organized into an optimal spanning-tree network to control the routing of data to and from the RF terminals and the host computer efficiently and dynamically.
