A system, method and device for adjusting a communication parameter for a network communicating with a communication device are provided. The method comprises: monitoring for a condition relating to a first network that has been in communication with the communication device; and determining whether an adjustment is to be implemented on a communication parameter of a second communication network that has been in communication with the communication device based on the condition and if so, implementing the adjustment to the communication parameter for the second communication network.

System and method for adjusting a power transmission level for a communication device

A system, method and device for adjusting communication parameters for networks communicating with a communication device are provided. The method comprises: when the communication device is linked to a first communication network and a second communication network, comparing a strength of received signals from the second network against a threshold; and when the strength of the received signals is less than the threshold, adjusting a network parameter of signals received from the second communication network by the communication device.

System and method for managing communications for two networks in a communication device

An electronic device monitors a quality of a wireless connection between the electronic device and a first access point. Based on the monitoring and a collection of parameters relating to controlling handover between access points, a determination is made regarding whether the electronic device should be handed over to a second access point from the first access point, where the parameters differ for different combinations of the first access point and candidate destination access points for handover of the electronic device from the first access point.

Mitigating interference with wireless communications

A system that incorporates teachings of the subject disclosure may include, for example, determining antenna coupling among a plurality of antennas of the communication device and adjusting beam forming for the plurality of antennas utilizing phase shifters coupled with radiating elements of the plurality of antennas, where the adjusting of the beam forming is based on forming a desired antenna pattern that increases radiated throughput and reduces the antenna coupling among the plurality of antennas. Other embodiments are disclosed.

Method and apparatus for beam forming and antenna tuning in a communication device

A mobile wireless communications device includes a wireless local area network (WLAN) radio configured to generate a WLAN transmit signal, and a Bluetooth radio configured to generate a Bluetooth transmit signal. A circulator is coupled downstream of an antenna. A transmit path couples the WLAN radio and the Bluetooth radio to the circulator such that the WLAN radio and the Bluetooth radio are capable of transmitting simultaneously. In addition, a receive path also couples the WLAN radio and the Bluetooth radio to the circulator such that the WLAN radio and the Bluetooth radio are capable of receiving simultaneously.
