A method includes determining a quality of service class identifier (QCI) level for an application running on a user device, selecting a connected mode discontinuous reception (CDRX) profile based on the QCI level, and transmitting the CDRX profile to the user device to be used when running the application. The QCI level may be indicative of delay sensitivity of the application and the CDRX profile may be selected based on the delay sensitivity of the application.

Dynamic connected discontinuous reception profile based on quality of service

An antenna system for an unmanned aerial vehicle (UAV) includes an antenna and a self-leveling antenna mount configured to mount the antenna to the UAV. The antenna is configured to receive commands for the UAV via a network and to transmit data from the UAV via the network. The antenna has a transmit-receive pattern with a peak strength in a first direction aligned with an axis of the antenna. The transmit-receive pattern falls off in directions away from the axis of the antenna. The self-leveling antenna mount is configured to adjust an orientation of the antenna to maintain substantial alignment between the first direction and a straight downward direction relative to the UAV despite a change in roll, pitch, or bank of the UAV. In some embodiments, the axis of the antenna is a downward vertical axis of the antenna.

Antenna system for unmanned aerial vehicle

An antenna system for an unmanned aerial vehicle (UAV) includes an antenna having a transmit-receive radiation pattern with a peak strength in a first direction of the antenna, a first strength reducing to a first predetermined strength below the peak strength at a first angle away from the first direction, a second strength reducing to a second predetermined strength lower than the first predetermined strength at a second angle greater than the first angle away from the first direction, and a third strength reducing to a third predetermined strength lower than the second predetermined strength at angles greater than the second angle away from the from the first direction. The antenna system further includes a self-leveling antenna mount to maintain the first direction in substantial alignment with a straight downward direction relative to the UAV despite a change in roll, pitch, or bank of the UAV.

Systems and methods are disclosed which relate to mitigating the detrimental effects of interference to electronic devices from mobile telephones utilizing any form of time-domain multiplexing technology. A wireless transmitter inside the mobile telephone broadcasts a warning transmission which can be received by affected devices. Once the warning transmission is received by an affected device, the device activates a blanking circuit comprising an actuator and a switch or switches. The switches open for the duration of the interference so that the user does not receive undesired output such as: noise through a speaker, noise through a microphone, or other interference with electrical signals.

Systems and methods for dampening TDMA interference

Disclosed is a device and method to automate the process of measuring RF noise, correlating measured noise with known sources, and making adjustments to the noise-measuring and reporting process. A wireless communication device is coupled to equipment at a fixed location, and transmits data about the operation of the equipment back to an operator, via a provider's network. Examples include fixed wireless terminals. A management entity aboard the wireless communication device performs the measurements via a transceiver and performs remedial actions when required, without requiring an onsite technician or remote assistance. The management entity may include a spectrum analyzer.

Assessing interference environment for wireless communication devices

Devices, systems, and methods are disclosed which relate to verifying an antenna via a transmitter. A logical interface coupled to a transmitter reads antenna specifications from a memory integrated with an antenna, and refuses transmission when the antenna attributes conflict with the requirements of the transmitter.

A wireless communications apparatus comprises a monitor component that analyzes transmitter operating parameters of the wireless communications apparatus. A generator component generates an acoustic anti-phase burst based at least in part upon the analyzed transmitter operating parameters, wherein the acoustic anti-phase burst reduces effects of radio frequency interference received at a hearing aid.

A system and method for antenna analysis and electromagnetic compatibility testing in a wireless device utilizes a 'parent' device that undergoes rigorous conventional testing. A 'child' device having similar components may thereafter undergo abbreviated testing. Because the Total Isotropic Sensitivity of the parent device is known, testing may be performed on the child device to infer equivalence to the parent's TIS performance using the abbreviated test techniques.

Parametric measurement of first- and second-generation telecommunications equipment has been relatively straightforward. The evolution to more complex transmission schemes such as those proposed for third-generation (3G) telecommunications devices can employ the subject methods and apparatus and apply AM-PM test procedures to a multicarrier amplifier RF environment to properly characterize the parametric performance of these transmission systems, particularly those operating in a multicarrier environment.
