1. A system for space division multiplexed communication between first elements in a first plane and second elements in a second plane, said first plane being substantially parallel to said second plane, said system comprising:

  • first transceivers disposed in an array according to a configuration at first access points in said first plane, each one of said first transceivers illuminating a radiation region over a substantial portion in said second plane; and

    at least one second transceiver disposed in said second plane in a host device, said second transceiver projecting a first radiation and reception pattern directly onto said first plane with functionally uniform radiation in a first field of view with preselected attenuation outside of said first field of view, said first radiation pattern being sufficiently narrow and positioned to capture one and only one of said first access points for a session of communication so that said first transceivers can control communication with multiple second transceivers and each said second transceiver can communicate with only one first transceiver.
