Abstract: Some embodiments concern a method of transmitting electrical signals. The method can include: using a global positioning satellite receiver to determine a first location of a first electrical device; using a first transmitter to transmit the first location to a first server; using a receiver to receive information identifying at least one first unused frequency at the first location from the first server; selecting a first transmission frequency from the at least one first unused frequency; and communicating the first transmission frequency to a user. Other embodiments are disclosed in this application.

Abstract: In some embodiments, a system can be configured to communicate to and from a media device. The media device can include a first controller. The system can include: (a) a software module configured to run on the first controller; (b) a physical device module configured to run on the first controller; (c) a virtual host module configured to run on the first controller; and (e) a docking station having: (1) a second controller; (2) an electrical connector configured to couple to the media device; (3) a physical host module configured to run on the second controller; (4) a virtual device module configured to run on the second controller; and (5) one or more accessory devices configured to communicate with the media device using the virtual device module. In some examples, the physical host module and the physical device module are configured to establish a physical communications pipe between the media device and the docking station.

Abstract: A selection and distribution unit (SDU) in a wireless radio access network is configured to receive signal quality information about a plurality of data streams, and based on the signal quality information, to select one of the plurality of data streams to be forwarded independently of the SDU. The data streams are associated with a call session from a mobile device and received by base transceiver stations, which provide the signal quality information about the received data streams to the SDU. Only one data stream is selected by the SDU for forwarding to a network device such as a PSTN gateway. The SDU provides a multicast address to the network device for transmitting data streams to the mobile device, and commands a base transceiver station to listen at that multicast address to receive the data stream. The SDU also establishes a multicast address for a plurality of base transceiver stations to receive commands from the SDU.
