Abstract: Multi-radio wireless network devices are capable of transmitting and/or receiving data from multiple radiofrequency (RF) networks at different bands. Total transmission power limitations may be in place due to, for example, safety reasons. As a result, active management of transmission power may be performed during simultaneous transmission in different bands and/or networks. In some embodiments, the management may take place on group-by-group basis and a network-by-network basis. Antennas may be grouped based on their relative positions and impact on radiation emitted by the devices.

Abstract: A device in an adaptive channel access system may include a processor that is configured initiate access of a channel, and perform a first jammer detection on the channel. The processor is configured to, when a jamming device is detected on the channel, access the channel with a channel occupancy time set to a first duration of time. The processor is configured to, when no jamming devices are detected: access the channel with the channel occupancy time set to the second duration of time that is greater than the first duration, while accessing the channel with the channel occupancy time set to the second duration of time, perform a second jammer detection on the channel, and when the jamming device is detected, cease to access the channel prior to the expiration of the second duration of time, otherwise continue to access the channel without re-initiating access of the channel.

Abstract: Methods and devices for reducing the power consumption and increasing the efficiency of an LTE transmitter of an electronic device are provided. By way of example, a method includes calculating location data related to a region in which the electronic device may operate via the electronic device, determining via the electronic device a region in which the electronic device is currently operating within based on the location data, and adjusting an output transmitting power of the electronic device based at least in part on the region and one or more frequency operating parameters utilized by the electronic device.
