Systems and methods for providing low latency and high bandwidth wireless data transport for various applications, such as virtual reality, augmented reality, or video applications.

The wireless data transport system utilizes the known position, orientation, or movement of the mobile wireless device receiving the data (e.g., video data) from the tracking subsystem and compensates for movement of the mobile wireless device by selectively adjusting the beamforming pattern of the steerable antenna based at least in part on the tracking data received from the tracking subsystem.

A method for radiating a co-located antenna including radiating the co-located antenna using a dual mode, where the co-located antenna has an inter-element spacing of about 1λ, and the dual mode includes a TM.sub.11 mode and a TM.sub.21 mode.
