522 results about "Wireless USB" patented technology

Wireless USB is a short-range, high-bandwidth wireless radio communication protocol created by the Wireless USB Promoter Group which intends to further increase the availability of general USB-based technologies. In large, IPv6 was a key of this technology. It is maintained by the WiMedia Alliance and (as of 2009) the current revision is 1.0, which was approved in 2005. Wireless USB is sometimes abbreviated as "WUSB", although the USB Implementers Forum discouraged this practice and instead prefers to call the technology Certified Wireless USB to distinguish it from the competing UWB standard.

System and method for a wireless unit acquiring a new internet protocol address when roaming between two subnets

In a wireless network system having a wired backbone network with two or more sub-networks, each having one or more access points for communicating with wireless units via a wireless transmission medium, a system, apparatus and method for a wireless unit to determine whether a candidate access point is on a different sub-network than its current access point. If the wireless unit determines that the candidate access point is on a different sub-network, then the wireless unit releases its current network protocol address which was valid for the current sub-network, and obtains a new network protocol address valid for the new sub-network. This is accomplished by the candidate access point transmitting a multicast packet that includes the network protocol address of the access point and the subnet mask of the sub-network which the access point is on. By receiving this multicast packet, the wireless unit can determine if the candidate access point is on a different sub-network than its current sub-network. Also disclosed is a technique for a wireless unit to determine whether to roam to a candidate access point based on the signal qualities to its current and candidate access points, and whether the candidate access point is on a different sub-network or a designated restricted sub-network.

System and method for data acquisition and process and processing

A system and method for data acquisition and processing is described which can form the basis of new and improved business and consumer services. A subscriber captures the image of an encoded datagram associated with a product or service using a mobile phone or PDA or fixed line device and transmits this to a remote data processing centre. The captured datagram may comprise a variety of geometric shapes and language characters and even some custom graphics which may be processed in relation to a subscriber's profile stored in the device. The profile is used to provide different levels of quality of service and authentication for access to services in accordance with the subscriber's access rights. The destination IP address or mobile number used to access the service is encoded within the datagram itself so the subscriber need only ‘point and click’ and the software application can both identify, decode and direct a newly compiled data message to a known destination. In this way a variety of datagrams may be created, each comprising their own unique destination mobile number or IP address where each may be associated with very unique data services or system control services. Communication with a specific data processing centre may be via fixed line ADSL or via 3G services or GPRS or WIMAX or Wireless USB or be converted into an SMS text message. The remote server processes the captured data and either provides information back to the sender of the information or to their email address or initiates a process. Applications include data services, process control such as car park barriers, secure software purchasing such as ordering games from magazines where the software is forwarded to a known email address. Other applications include timetable updates for travel guides, or on advertisements, or in technical journals, or on food constituent labels, so that the data can be compared with current source data and dynamically updated as required to thereby replace or enhance the published information.
