  • Patent number: 9755724
    Abstract: The present disclosure relates to an electronic apparatus for determining a relay apparatus and a method thereof. An electronic apparatus according to various embodiments includes a communication unit that transmits and receives data. The electronic apparatus also includes a controller that determines whether disconnection between an electronic apparatus operating as a relay apparatus and at least one client apparatus is expected. The control also, if the disconnection is expected, informs the at least one client apparatus of the expected disconnection. The control also determines whether a status of the electronic apparatus satisfies a condition for a change to a new relay apparatus and informs the at least one client apparatus that the electronic apparatus no longer operates as the relay apparatus if the condition for a change to a new relay apparatus is satisfied. The control also determines any one of the at least one client apparatus as the new relay apparatus.

  • Patent number: 9692122
    Abstract: An active antenna system and algorithm is described that provides for dynamic tuning and optimization of antenna system parameters for a MIMO system where correlation and isolation between antennas in the system are dynamically altered to provide for greater throughput. As one or multiple antennas are loaded or de-tuned due to environmental changes, corrections to correlation and/or isolation are made by selecting the optimal antenna radiation pattern and by adjusting electrical length and/or reactive loading of transmission lines connecting the antennas. Multiple Isolated Magnetic Dipole (IMD) antennas are co-located and connected with a feed network that can include switches that adjust phase length for transmission lines connecting the antennas. Filtering is integrated into the feed network to improve rejection of unwanted frequencies. Filtering can also be implemented on the antenna structure.
