Abstract: The present invention provides a method for transmitting voice packet data over a selected one of a first network in which multiple devices belonging to a defined set communicate with each other according to a first protocol and a second network in which multiple devices communicate with each other according to a second protocol, different from the first protocol. The method includes establishing at least one radio bearer between at least two devices in the first network according to the first protocol, receiving at least one voice packet that conforms to the second protocol, modifying the at least one voice packet to conform to the first and the second protocols, and transmitting the at least one modified voice packet using the at least one radio bearer.

Abstract: Multiple out-of-plane planar reflectors can be used to build a receive/transmit high-gain directional antenna. The driver portion and the first reflector of the antenna are formed within a metal layer of a PWB. A plurality of sets of reflector plates can be placed on the PWB, on a non-conductive low-dielectric constant material coating both opposing planar surfaces of the PWB, or on the opposing sidewalls of the product housing unit. The metal layer in the PWB is placed between the reflector plates. The plates can have either a parallel or non-parallel orientation to each another. This greatly increase the received power and thus increases the operating range of a low-power UWB system, as well as significantly improves wireless data transmission throughput. This antenna is applicable for USB communications systems.

Abstract: Certified Wireless USB 1.0 (CWUSB) defines two different types of association: cable association and numeric association. In the numeric association, the CWUSB host and device use a specific protocol to exchange the security information. At final stage of this information exchange, both host and device need to display a number asking user's feedback. Once this is done, both host and device will be able to generate the connection key as the shared secret for the following secured communication. One problem of this numeric association method is that device needs to be able to display the numbers. For certain class of device that has capability to display an image, there is a natural way to add this function to them. A method for this class of devices is described. Another kind of association, which is not defined in the CWUSB 1.0, is manual association. User needs only to manually type in the Connection Key coming from the CWUSB device.

Abstract: Universal Serial Bus (USB) is a Master/Salve or Host/Device system in which there is only one host and one or more devices connected by cables to the host. To connect a USB device to a different host controller (say another PC), the user unplugs the USB cable and establishes the connection physically by plugging the cable into the new host controller interface. Certified Wireless USB (CWUSB), a logical extension to the USB, preserves the USB connection model, except that the link between the host and the device is now using a wireless technology. A wireless device is usually connected to only one wireless host at a given point of time, even though several wireless hosts may be co-located in the same physical neighborhood. The connection between the wireless host and device is initiated by the device. A device usually selects a wireless host from a stored set of known hosts that have established a trusted relationship with the device.

Abstract: The present invention provides a method is provided for soft vertical handovers. The method includes requesting a handover from a first wireless network that operates according to a first protocol to a second wireless network that operates according to a second protocol, the first protocol being different than the second protocol, via a first wireless telecommunication link that operates according to the first protocol. The method also includes forming, in response to the handover request, a second wireless telecommunications link according to the first and second protocols, the second wireless telecommunications link being concurrent with the first wireless telecommunication link. The method further includes dropping the first wireless telecommunications link after forming the second wireless telecommunications link.

Abstract: The present invention provides methods for detecting a wireless air interface. The method includes receiving information indicative of at least one wireless access type, determining whether the information indicative of the at least one wireless access type is within an expected range, performing at least one first measurement associated with a first air interface in response to determining that the information indicative of the at least one wireless access type is within the expected range, and performing at least one second measurement associated with a second air interface in response to determining that the information indicative of the at least one wireless access type is not within the expected range.

Abstract: Certified Wireless USB 1.0 defines two different types of association: cable association and numeric association. In order to implementation these two association methods, the CWUSB device needs to have either upstream USB connector (for cable association) or display capability (for numeric association). These extra requirements make the CWUSB device bulkier (one more USB connector) and/or more expensive (extra display components). For cheap and simple CWUSB devices, we need a simpler association method that is easy and cheap to implement. In a pre-packaged total solution, which includes a host and one or more device(s), we can use pre-association to smooth the user experience. The host and device(s) are pre-associated. When an end user starts to use this solution, they do not need to worry about the association at all.
