Abstract: In order to maintain performance during wireless communication, a transmitting electronic device may selectively perform a remedial action based on a received power in a channel during time intervals between received packets (e.g., due to interference) and/or a metric associated with the measured received power. In particular, when the received power is less than a threshold value (e.g., when the interference is insufficient to stop transmission by the transmitting electronic device), the transmitting electronic device performs the remedial action based on the measured received power and/or the metric. For example, the remedial action may include: selecting a modulation technique; selecting the receiving electronic device; selecting an antenna pattern for the one or more antennas; reducing a transmit power; selecting a data rate; determining a cumulative distribution function; and/or estimating a channel capacity.

Abstract: Power consumption in a receiving device is avoided by receiving packets from a transmitting device in a first band of frequencies (such as around 60 GHz) and providing acknowledgments in a second band of frequencies that is different than the first band of frequencies (such as around 5 GHz). These out-of-band acknowledgments may allow the receiving device to avoid transmissions in the first band of frequencies and the associated power consumption. Moreover, the transmissions by the transmitting device in the first band of frequencies and the second band of frequencies may be synchronized so that packets are transmitted in the first band of frequencies when transmission in the second band of frequencies is enabled. In these ways, this communication technique may improve the performance of the transmitting device and the receiving device.

Abstract: 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.

Abstract: A system and method for a wireless link to a remote receiver includes a communication device for generating RF and a planar antenna apparatus for transmitting the RF. The planar antenna apparatus includes selectable antenna elements, each of which has gain and a directional radiation pattern. The directional radiation pattern is substantially in the plane of the antenna apparatus. Switching different antenna elements results in a configurable radiation pattern. Alternatively, selecting all or substantially all elements results in an omnidirectional radiation pattern. One or more directors and/or one or more reflectors may be included to constrict the directional radiation pattern. The antenna apparatus may be conformally mounted to a housing containing the communication device and the antenna apparatus.

The processor receives the position information from the position sensor, 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 of the selected antenna configuration.

Abstract: A mountable antenna element is constructed as an object from a single piece of material and can be configured to transmit and receive RF signals, achieve optimized impedance values, and operate in a concurrent dual-band system. The mountable antenna element may have one or more legs, an RF signal feed, and one or impedance matching elements. The legs and RF signal feed can be coupled to a circuit board. The impedance matching elements can be utilized to create a capacitance with a portion of the circuit board and thereby optimize impedance of the antenna element at a desired operating frequency. The mountable antenna includes features that enable it for use in concurrent dual band operation with the wireless device. Because the mountable antenna element can be installed without needing additional circuitry for matching impedance and can be constructed from a single piece of material, the antenna element provides for more efficient manufacturing.
