Abstract: Systems and methods for multi-carrier frequency grip detection are described. For example, a method may include determining a first signal strength of a first signal received using a first antenna from a source device; determining a second signal strength of a second signal received using a second antenna from the source device; comparing the first signal strength with the second signal strength; and detecting a detuned condition for a device including the first antenna and the second antenna based on the comparison of the first signal strength with the second signal strength.

Abstract: In some implementations, the disclosed techniques may include tuning a first antenna element to a first tuning state during an acquisition mode for establishing communication channels with satellites. The first tuning state can configure the first antenna element to receive signals in a first frequency range. The techniques may include establishing the communication channels using the first antenna element in the first tuning state during the acquisition mode. The techniques may include transitioning from the acquisition mode to a tracking mode. The techniques may include changing the tuning state of the first antenna element. The techniques may include determining a location of the mobile device during the tracking mode: (1) using the first antenna element and a second antenna element of the mobile device or (2) not using the first antenna element and using the second antenna element that is configured to receive signals in a second frequency range.

Abstract: Systems, methods, and devices are provided for dynamically determining appropriate antenna tuning states for communication across one or more frequency bands. An electronic device may include a radio frequency system that facilitates wireless transmission and reception of data across multiple frequency bands. The electronic device may include a processor coupled to the radio frequency system. The processor may instruct the radio frequency system to obtain measurements for a candidate tuner state and a tuner state. Further, the processor may instruct the radio frequency system to determine whether the candidate tuner state provides better radio frequency system performance than the tuner state. Additionally, the processor may update the tuning table to reflect that results of which tuner state provides better radio frequency system performance.
