摘要： The principles of the present invention provide for using directional antennas to adaptively communicate in a wireless mesh network. A number of infrastructure components are included in a wireless mesh network environment. Each infrastructure component includes an omni-directional antenna and one or more directional antennas (e.g., electronically steered phased array antennas) that can be used to communicate with other infrastructure component and wireless devices. Directional antennas can utilize one or more directional beams that can be directed towards an infrastructure component or wireless device to communicate with the infrastructure component or wireless device. Infrastructure components can adapt to communicate with the same destination through different intermediary infrastructure components. Since the signal strength of a directional beam can be greater than that of an omni-directional antenna of the same gain, infrastructure components can be separated by greater distances.

摘要： The principles of the present invention provides for using directional antennas to mitigate the effects of interference in a wireless network. An antenna device includes an omni-directional antenna and at least one directional antenna. Each directional antenna (e.g., an electronically steered phased array antenna) can have one or more feeds for directing beams at wireless devices. The antenna device utilizes the omni-directional antenna to send and receive control data that facilitates locating wireless devices and determining when a wireless device is to send program data to or receive program data from the antenna device. The antenna device utilizes directional antennas to send program data to and receive program data from wireless devices. Since directional antennas use directional beams, directional antennas can be tuned channels with reduced interference based on the location of wireless devices relative to the antenna device.
