Appl. No.:

10/771532

Inventors:

Stephen Palm - Irvine CA, US
Edward H. Frank - Atherton CA, US
Bruce E. Edwards - Belmont MA, US

Assignee:

Broadcom Corporation - Irvine CA

International Classification:

H04Q 7/24

US Classification:

370338, 370311

Abstract:

A Wireless Local Area Network (WLAN) system in which wireless terminals each operate upon battery power. One of the wireless terminals acts as a Master to coordinate the transmission and receptions of the Slaves so as to reduce the power consumed by all of the devices. The Slaves operate according to a power up and power down sequence to conserve battery power. Further, the terminals may alternate between being Slaves and being the Master to equalize battery consumption of the wireless terminals.

US Classification:

455458, 455574, 375354

Abstract:

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.

International Classification:

H04M 1/56

US Classification:

37914202, 37920102

Abstract:

A system for selectively blocking and unblocking the sending of outgoing caller ID information from a communication device comprises a communication device, a processor coupled to the communication device and a storage medium coupled to the processor containing a directory of information entries. The information entries include both telephone numbers and associated security levels. When a call is placed to a number using the communication device, the processor seeks the number in the directory of the storage medium. If an entry is found for the number by the processor, caller ID information is prevented from being sent to the number unless a security level associated with the number is at or above a predefined cut-off level.

Abstract:

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.

International Classification:

US Classification:

370338, 370310

Abstract:

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.
