A method, apparatus and computer program product for wireless charging are provided. An indicator displayed on a wireless device may assist a user in placing the device in a more efficient position on a wireless charger. The indicator may comprise an image, and moving the device such that the image aligns with an image on a wireless charger places the device is in a more efficient charging position. Other types of indicators may be displayed to assist a user in moving a device to a more efficient position on the wireless charger.

Method and apparatus for improved wireless charging efficiency

The present invention provides methods and apparatuses for utilizing unused portions of an allocated frequency spectrum in a wireless communications system that broadcasts content to wireless stations. A first wireless station may communicate with a second wireless station on an idle broadcast channel while keeping the resulting interference level below an acceptable maximum limit at the other wireless stations. Using interference level information that are measured at the wireless stations, the wireless station can negotiate with the other wireless station on an establishment channel for subsequent communications on one or more broadcast channels. The wireless station may receive broadcast content on a time slice that corresponds to a broadcast channel and that is further processed by the wireless station. Otherwise, the wireless station can utilize the corresponding time to measure an interference level for the corresponding channel or to transmit or receive data to/from another wireless station.

System and method utilizing a cognitive transceiver for ad hoc networking

Various example embodiments are disclosed relating to wireless networks, such as relating to techniques to improve coverage of push-to-talk wireless networks or services. In an example embodiment, a technique may include forwarding data to a remote push-to-talk (PTT) wireless network via an intermediary device of an intermediary wireless network if the data is received from a wireless device of a local push-to-talk (PTT) wireless network, forwarding data directly to one or more wireless devices of the local PTT wireless network if the data is received from the remote PTT wireless network via the intermediary device, and forwarding data to one or more wireless devices of the local PTT wireless network and to the remote PTT wireless network via the intermediary device of the intermediary wireless network if the data is generated locally.

Techniques to increase coverage of push-to-talk wireless networks

Apparatus, and associated method, for dynamically selecting frequencies upon which to define communication channels in a communication system, such as a wireless mesh network. Frequency levels are selected for global use throughout the entire mesh network. And, frequency levels upon which to define local communication channels for individual nodes of the mesh network are also selectable.
