Abstract: Various disclosed embodiments include methods and systems for operating a wireless electronic device having one or more antennas. The method comprises monitoring at least one parameter of a signal received from a remote transmitter. The method includes determining that the at least one parameter meets a first threshold and performing, at the wireless electronic device, a probing operation. The probing operation includes performing an antenna switching operation. The probing operation includes generating first signal information of the received signal prior to the antenna switching operation and generating second signal information of the received signal subsequent to the antenna switching operation. The probing operation includes determining whether the antenna switching operation achieves a desired gain based at least in part on the generated first and second signal information. The probing operation includes reversing the antenna switching operation in response to the desired gain not being achieved.

Abstract: An antenna's resonance frequency is detuned when a part of a human body approaches or contacts the antenna and consequently results in efficiency loss. The antenna may be tuned by changing its total load capacitance such that the antenna's total load capacitance falls within a reference capacitance range of a reference capacitance, where the antenna can operate at or near its pre-determined operating resonance frequency. A tunable capacitor may be coupled to the antenna for tuning the total load capacitance of the antenna.

Abstract: A system and method for improving the user experience with a mobile wireless device by reconnecting to a faster speed connection after being rejected for the higher speed by an overloaded cell before expiration of a de-prioritization timer when the mobile wireless device travels away from the overloaded cell. In an embodiment, a method includes receiving from the first cell a connection rejection instructing the mobile wireless device to de-prioritize one or more frequencies of the first connection technology and a de-prioritization timer indicating a time period for the frequencies to remain de-prioritized; determining that the mobile wireless device has left the coverage area of the first cell; and connecting to a second cell of the telecommunication network via a connection in the one or more frequencies of the first connection technology prior to the expiration of the de-prioritization timer.
