Methods and systems for wireless packet switching include determining a schedule for transceivers in an enclosure. The schedule specifies which of the transceivers will act as a transmitter and which will act as a receiver. A beamforming direction for transmitting data from each transmitter to each corresponding receiver is determined. It is determined that an angle of the beamforming direction for at least one transmitter is lower than a minimum angle. Data is transmitted from a transmitter to the corresponding receiver by a wired connection, responsive to the determination that the angle of the beamforming direction is lower than a minimum angle.
