    摘要: Synchronized UWB piconets for SOP (Simultaneously Operating Piconet) performance. A common backbone (either wired or wireless) is employed that provides a common CLK (clock signal) to all of the various PNCs (piconet coordinators) of various piconets that may operate within a sufficiently close region such that interference could undesirably occur. By providing a very reliable CLK signal from a common backbone to all of the PNCs of the various piconets operating within a substantially close proximity to one another, very precise synchronization may be ensured for all of the communications performed therein. The various piconets may then even operate using TDMA (Time Division Multiple Access)—whose performance would be substantially compromised without effective synchronization. In addition, combined TFC (time frequency code) and TDMA may also be employed to support the communications therein thereby providing even another degree of orthogonality that provided by TDMA alone.

    摘要: A method for revoking access to a mobile device includes providing a plurality of authenticated applications accessible by the mobile device, and providing a plurality of revocation timeout intervals for revoking access by the mobile device to the plurality of authenticated applications. Access to a first authenticated application is revoked after a first timeout interval and access to a second authenticated application is revoked after a second timeout interval.

    摘要: Multi-mode WLAN/PAN MAC. A novel solution is presented in which a MAC (Medium Access Controller) is implemented that includes multiple functionality types. This MAC may include functionality supporting communication according to one or more of the IEEE 802.11 WLAN (Wireless Local Area Network) related standards and also to one or more of the standards generated by the IEEE 802.15.3 PAN (Personal Area Network) working group. By providing this dual functionality of a multi-mode WLAN/PAN MAC, a communication device may adaptively change the manner in which it communicates with other communication devices. For example, in an effort to maximize throughput and overall efficiency of communication within a communication system, certain of the various devices may change from using the WLAN related standards to using the PAN related standards, and vice versa, based on any one or more of a variety of operational parameters including system configuration.

    摘要: A Wireless Local Area Network (WLAN) system based upon peer-to-peer communications. A wireless terminal for peer-to-peer communications acts either as a WLAN master or as a WLAN slave. When the wireless terminal acts a master, the wireless terminal undertakes mastering duties that include transmitting a beacon interval in the frame cycle. When the wireless terminal is not tethered to a power source, mastering duties alternate according to a round-robin WLAN mastering cycle, wherein the wireless terminal acts the WLAN master during at least one frame cycle and acts the WLAN slave during other frame cycles to conserve an untethered power source of the wireless terminal.

    摘要: Methods and systems are provided that authenticate an intended user of a mobile client in a roaming environment. One embodiment of the invention provides a mobile communication network architecture that includes a first base station (e.g., a first base station controller and/or a first transceiver station), a second base station (e.g., a second base station controller and/or a second transceiver station), a mobile client, and a server coupled to the mobile client via either the first base station controller or the second base station. The first base station is coupled to an authentication center that authenticates an intended user so that the user can communicate a message between the mobile client and the server via the first base station. A credential (or status) of the authentication made at the authentication center is then transmitted from the first base station to the second base station when the mobile client moves to utilize the second base station to communicate with the server.

    摘要: A wireless interface device services communications between a wirelessly enabled host and at least one user input device. The wireless interface device includes a wireless interface unit, a processing unit, an input/output unit, and may include a power management unit. The wireless interface unit wirelessly interfaces with the wirelessly enabled host. The processing unit and the wireless interface unit interact to determine when the wireless interface unit has established a link with the wirelessly enabled host. When the wireless interface unit has established a link with the wirelessly enabled host, the processing unit interacts with the input/output unit to direct the input/output unit to output a link established indication. When the wireless interface unit enters a sniff mode or a park mode, a second link established indication may be provided. When the link is taken down or lost, a link non-established indication may be provided.

    摘要: A modem and method for operating same. A receiver circuit of the modem is coupled to receive a continuous analog signal from a communication channel. This analog signal includes both packet and idle information. The receiver circuit monitors the analog signal to detect the presence of idle information. Upon detecting idle information, the receiver circuit enters a standby mode in which the processing requirements of the receiver circuit are reduced. A burst mode protocol is also provided, in which packets of digital information are modulated by a transmitter circuit the modem, thereby converting the packets of digital information into analog signal bursts of discrete duration. These analog signal bursts are transmitted from the transmitter circuit to a telephone line. However, the transmitter circuit does not generate any signals between the analog signal bursts. A receiver circuit monitors the telephone line to detect the analog signal bursts. Upon detecting the presence of the analog signal bursts on the telephone line, the receiver circuit demodulates the analog signal bursts using full processing capabilities of the receiver circuit. However, upon detecting the absence of the analog signal bursts on the telephone line, the demodulating function of the receiver circuit is disabled. The burst mode protocol enables multi-drop and multi-cast operation, as well as reducing required DSP resources.
