    摘要： A device (300) for a wireless RF link to a remote receiving device can radiate at different radiation patterns in response to detecting a change in the device position. As the device (300) is moved, displaced, or re-positioned, a position sensor (315; 320) in the device (300) detects the change in position and provides position information to a processor (310). The processor (310) receives the position information from the position sensor (315; 320), selects an antenna configuration and physical data rate based on the position information, and provides an RF signal associated with the selected antenna configuration through the antenna elements (355) of the selected antenna configuration.

    摘要： A horizontally polarized antenna array allows for the efficient distribution of RF energy into a communications environment through selectable antenna elements and redirectors that create a particular radiation pattern such as a substantially omnidirectional radiation pattern. In conjunction with a vertically polarized array, a particular high-gain wireless environment may be created such that one environment does not interfere with other nearby wireless environments and avoids interference created by those other environments. Lower gain patterns may also be created by using particular configurations of a horizontal and/or vertical antenna array. In a preferred embodiment, the antenna systems disclosed herein are utilized in a multiple-input, multiple-output (MIMO) wireless environment.

    摘要： A system and method for improved data transmission on a wireless link to a remote receiving node includes a communication device for converting packets to RF at a physical data rate, an antenna apparatus having a plurality of antenna configurations for transmitting the RF, and a processor for selecting the antenna configuration and the physical data rate based on whether the remote receiving node indicated reception of the data transmission. The processor may determine a table of success ratios for each antenna configuration and may rank each antenna configuration by the success ratio. The processor may transmit with an unused antenna configuration to probe the unused antenna configuration and update the table of success ratios. Similarly, the processor may maintain a table of effective user data rates, rank each physical data rate by the effective user data rate and probe unused physical data rates to update the table.

    摘要： A radio node may calculate one or more performance metrics based on measured satellite signals, which are associated with a global positioning system, or wireless signals that are associated with a cellular-telephone network. Then, the radio node may determine, based on the one or more performance metrics, whether the radio node is a synchronization master in a cluster of radio nodes. When the radio node is the synchronization master, the radio node may provide information intended for a computer specifying that the radio node is the synchronization master and the one or more performance metrics. In response, the radio node may receive a synchronization request associated with another radio node in the cluster. Furthermore, the radio node may provide the synchronization information intended for the other radio node, where the synchronization information specifies time, frequency, and phase synchronization for at least the cluster.

    摘要： A communication technique for synchronizing a set of radio nodes is described. In this communication technique, the radio node arbitrates (e.g., using a precision time protocol or PTP) with the other radio nodes based on a selection technique to select a synchronization master in the set of radio nodes. This synchronization master may be selected to have a predefined performance based on a type of communication environment of the set of radio nodes. For example, the type of communication environment may include overlap between at least one of the radio nodes in the set of radio nodes and a macrocell in a cellular-telephone network, or may exclude overlap between the set of radio nodes and the macrocell. The synchronization master may specify time, frequency, and phase synchronization for the set of radio nodes. When the synchronization master is different from the radio node, the radio node synchronizes with the synchronization master.
