A beam pattern of a base station antenna is refined when communicating with multiple aircraft, so that interference to adjacent beams from the base station are reduced. The method include receiving position locations from each of multiple aircraft. The method also include the receipt of an attitude of each of the aircraft as well as receipt of measurements of the pilot signals from each of the aircraft. The pilot signals were transmitted by the base station. The method also include the adjustment of an amplitude and a phase of a signal driving at least one antenna transmit element to refine the beam pattern. The adjustment is based at least in part on the pilot measurements, the position locations, and the attitude of each of the aircraft.

Aspects of the disclosure provide a handoff procedure for a satellite communication system such as a broadband low-Earth orbit (LEO) satellite communication system. A gateway and a user terminal (UT) coordinate and schedule a satellite-to-satellite handoff in such a way that there are no messaging round-trip delays between the last return service link (RSL) packet transmitted from the user terminal to the source satellite and the first RSL packet transmitted from the user terminal to the target satellite. Therefore, an outage on the return link (from the user terminal to the gateway) can be limited to the actual time for moving the antenna feed from the source satellite to the target satellite. Furthermore, an outage on the forward link (from the gateway to the user terminal) can be limited to a single round-trip delay in addition to the time for moving the antenna feed.

A method and apparatus for establishing a communication link between a user terminal and a first satellite associated with a first satellite service are disclosed. The user terminal determines a position of the user terminal based, at least in part, on location information provided by a satellite positioning system (SPS) receiver associated with the user terminal, determines a reference azimuth of the user terminal based, at least in part, on a position of a second satellite associated with a second satellite service that is different than the first satellite service, obtains ephemeris data for the first satellite, and aligns a directional antenna of the user terminal with the first satellite based, at least in part, on the position of the user terminal, the reference azimuth of the user terminal, and the received ephemeris data.

Wireless power and data transfer for electronic devices

Exemplary charging device includes a processor and charging current for coupling to a battery. In an exemplary embodiment, the processor defines charging profiles for charging the battery at different charge rates. A profile can be selected based on a determinable time event and may be modified based on a charging history. Adjustable charging power is supplied to the battery at a power level, a charging duration, or a combination thereof based on the selected profile. A wireless power transmitter can also define charging profiles and charging histories for receivers that receive power from the transmitter based on an identifier from the receiver. The transmitter can select the charging profile based on a determinable time event and may be modified based on a charging history. The transmitter supplies power through the wireless power link at a power level, a charging duration, or a combination thereof based on the selected profile.

Energy storage device security

Methods and apparatus are described for overcoming interference in a multicarrier communication system by applying different antenna configurations to each carrier in a multi-carrier base station based on channel conditions specific to the carrier. Each carrier may be assigned to a different antenna element configuration, each configuration providing a different coverage area. Different portions of a data stream may be transmitted simultaneously via each carrier, the amount of data in each portion of the data stream being defined based on the channel conditions.

Method and apparatus for multicarrier coverage diversity

A system and method places signaling message frames in a traffic channel carrying voice frames so that the signaling message transmission does not seriously impact voice quality. This is accomplished by producing a first stream of voice encoded packets and a second stream of signaling message packets. The signaling message packets are prioritized in the second stream relative to the voice encoded packets in the first stream. An arbitration element arbitrates between the voice encoded and prioritized signaling message packets, which are multiplexed as a function of this arbitration. The multiplexed voice encoded and prioritized signaling message packets are then transmitted.

System and method for prioritizing traffic channel messages

A portable wireless communications device such as a telephone handset having a vertically corrected antenna module pivotally secured to the handset for rotation about a first pivot axis. The antenna module can be rotated into a predetermined orientation, independent of handset orientation. An antenna mounted on the module is oriented vertically when the module is in the predetermined orientation. When the antenna module is rotated for use, a mechanism incorporated in the module support structure automatically rotates the antenna module about a second pivot axis which is substantially perpendicular to the first. This second rotation places the antenna at an angle that compensates for tilting of the handset during use about an axis parallel to the second axis, or along the first. That is, the antenna is shifted by a preselected angle in vertical orientation, typically around 10-15 degrees, in a direction perpendicular to the first direction of rotation to compensate for positioning a speaker and microphone for use.
