An antenna array is formed by a network of transceivers that includes unit radios and a command radio. The command radio configures the antenna array and communicates with the unit radios to send and receive signals. The unit radios may form an antenna array with greater than half-wavelength spacing and the command radio receives signals from another radio through a unit radio receiving a best signal or from combined signals from several unit radios received from the other radio. The unit radios may form an antenna array having half wavelength or less spacing that forms a digital beam forming antenna with an antenna grid to which the unit radios are connected.

A method of delivering programming to passenger seats with a wireless in-flight entertainment system in an aircraft cabin uses a configurable cabin antenna system. Control data and programming is delivered with a head end server and received with one or more access points connected to the head end server. One or more antenna systems, connected to the access points, are disposed at optimum selected locations in the aircraft cabin to provide the programming to the passengers. One or more personal electronic devices (PEDs) located receive the programming from the one or more configurable antennas. Beams of the one or more antenna systems are adjusted to deliver programming to the one or more PEDs at a required bit error rate.
