    Abstract: Exemplary embodiments include a system having a first wireless audio output device and a second wireless audio output device. One of the first or second audio output devices is configured to one of connect as a slave to a source device in a first piconet and connect as a master to the other one of the first or second audio output devices in a second piconet. The one of the first or second wireless audio output devices determines whether an audio packet transmitted by the source device via the first piconet was received by the first wireless audio output device and the second wireless audio output device, and, when at least one of the first wireless audio output device or the second wireless audio output device did not receive the audio packet, the audio packet is exchanged between the first and second wireless audio output devices via the second piconet.

    Abstract: In order to improve the quality of communication between electronic devices, one or more sub-channels used during communication between the electronic devices are dynamically modified based on one or more performance metrics and allowed transmit powers of the sub-channels. In particular, when the one or more performance metrics indicate that a distance between the electronic devices falls within a mid-range of distances, the one or more performance metrics may be used to guide selective changes to the sub-channels used during the communication based on the allowed transmit powers. The changes to the sub-channels used during the communication may increase, decrease or leave the total bandwidth unchanged. Moreover, by changing the sub-channels used during the communication, the allowed transmit power(s) of the sub-channel(s) used may be increased, which may improve the performance during the communication.

    Abstract translation: 为了提高电子设备之间的通信质量，基于一个或多个性能度量和子信道的允许发送功率动态地修改在电子设备之间通信期间使用的一个或多个子信道。 特别地，当一个或多个性能度量指示电子设备之间的距离落在距离的中间范围内时，可以使用一个或多个性能度量来指导在基于通信期间使用的子信道的选择性改变 关于允许的发射功率。 在通信期间使用的子信道的改变可以增加，减少或保持总带宽不变。 此外，通过改变在通信期间使用的子信道，可以增加所使用的子信道的允许发送功率，这可以提高通信期间的性能。

    Abstract: Apparatus and methods for rapid, cost effective testing of wireless systems. In one embodiment, a unit under test (UUT) is tested by a test “server”. The UUT and test server communicate via a “connectionless” protocol which is based on beacons (and beacon responses) which can carry one or more test primitives. The aforementioned “connection-less” test protocol can be performed without wireless network configuration, which greatly reduces test time, Additionally, exemplary solutions are presented for “lock-up” of the UUT and the test server.
