Abstract: Methods and apparatus for controlling the communications between a wireless microphone receiver and one or more wireless microphone transmitters are described. In accordance with some embodiments a common control channel is used for communicating control signals between the wireless microphone receiver and one or more wireless microphone transmitters, while separate audio data channels are used to carry audio data traffic from each individual wireless microphone transmitter to the microphone receiver. In accordance with some other embodiment, a time division approach is used in which there are microphone transmit time periods and control signaling time periods. During the microphone transmit time periods, wireless microphone transmitters transmit audio data signals and, in some embodiment, control signals, to the wireless microphone receiver using separate frequency subbands within a frequency band.

Abstract: A wireless microphone receiver is used to control transmission power and/or channel configuration of wireless microphones which communicate audio data to the wireless microphone receiver. In some embodiments the wireless microphone receiver searches for available channels, e.g., on a periodic or other basis. Based on wireless microphone receiver loading and interference considerations, channel availability may be determined and channel assignments are made. In some embodiments channel assignments are made based on wireless microphone battery status. Channel assignments to wireless microphones are communicated via a control channel. In addition to channel assignments, wireless microphone transmitter power can be controlled by the wireless microphone receiver. Commands to increase or decrease transmission power may occur as channel conditions change and/or on a recurring periodic basis. The rate of power control transmission may be relatively infrequent, e.g.

Abstract: Methods and apparatus related to timing synchronization used in a wireless microphone system to reduce and/or minimize interference are described. A wireless microphone receiver in some embodiments performs open loop timing control based on signals from an adjacent wireless microphone receiver and participates in closed loop timing control of wireless microphone transmitters which communicate with the particular wireless microphone receiver. The closed loop timing control includes instructing individual wireless microphone transmitters to advance or retard their symbol timing so that symbols transmitted by different wireless microphone transmitters are received in a synchronized manner at the wireless microphone receiver.

The method includes receiving a signal from a remote device, determining an identification and a relative bearing of the remote device based on the signal and displaying the identification and the relative bearing of the remote device. The apparatus for operating a local device to discover proximal information includes a processor configured to receive a signal from a remote device and determine an identification and a relative bearing of the remote device based on the signal and a display coupled to the processor, the display configured to display the identification and the relative bearing of the remote device.

Abstract: Methods and apparatus related to communicating advertisements and/or service announcements to devices in a communications system are described. In various embodiments mobile devices are used as mobile advertisement transmission platforms. Advertisements may be downloaded to the wireless communications device along with transmission constraints. Transmission of an advertisement is made when a transmission constraint, e.g., target audience constraint is satisfied. The wireless terminal may change its transmission frequency, coding rate and/or other transmission characteristics to satisfy a transmission constraint and/or optimize revenue. The mobile device reports advertisements transmissions to a network device, e.g., advertisement server and the owner of the device is compensated for the transmissions. Transmission constraints may involve a number of devices to be reached, the type of devices to be reached, and/or other constraints relating to the demographics of device users.

Abstract: An apparatus and associated method is provided for facilitating policy decision in a communication system, wherein the apparatus receiving a message, the message comprising a first destination device identification of a first destination device, determining a second destination device identification of a second destination device by accessing a location information of a wireless terminal, and replacing the first destination device identification with second destination device identification.

Abstract: The claimed subject matter relates to systems and methods for roaming in a wireless communications environment. A method for roaming between networks is provided in one aspect. This includes receiving a request for network access at a visited network and receiving a profile from a home network in response to the request. Upon receiving the profile, selectively offering services to one or more access terminals based at least in part on the profile.

Abstract: A routing system and method utilizes a highly-adaptive, loop-free, distributed routing algorithm for dynamic networks. The basic, underlying method is neither a distance-vector nor a link-state method; the invention employs an algorithm which is one of a family of algorithms which are called “link reversal” algorithms. The protocol's reaction is structured as a sequence of diffusing computations, each computation consisting of a sequence of directed link reversals. This behavior is achieved, in part, through the use of a “physical or logical clock” to establish the temporal order of topological change events. A key concept in the protocol's design; is an attempt to decouple (to the greatest extent possible) the generation of far-reaching control message propagation from the dynamics of the network topology. These design characteristics make the protocol highly-adaptive, efficient and scalable-being best-suited for use in large, dynamic, bandwidth-constrained networks.
