ABSTRACT:
The principles of the present invention provides for using directional antennas to increase signal strength and enhance throughput 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 to 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 the directional antenna to send program data to and receive program data from wireless devices. Since the directional antennas use directional beams, the range and barrier penetration of directional antennas is greater than that of the omni-directional antenna.
