Systems and methods are described to concurrently utilize actively used spectrum for new TDD or FDD networks, and also for enabling Distributed-Input Distributed Output (DIDO) techniques to be used with both the new networks and the existing networks in the same spectrum.

Systems and methods for concurrent spectrum usage within actively used spectrum

Systems and methods are described to mitigate interference to out of band receivers using out of band training signals.

Systems and methods for mitigating interference within actively used spectrum

Systems and methods are described to create radio daisy chains for convenient and aesthetically pleasing high-density radio deployments.

Systems and methods for distributing radioheads

An apparatus, system, and method for mitigating interference within an actively used spectrum. For example, one embodiment of a system comprises: a first wireless network operating with a first protocol and comprising a plurality of wireless transceiver stations that share a cell ID and collectively transmit a plurality of simultaneous non-interfering precoded data streams to a plurality of user equipment (UE) within the same frequency band, a second wireless network operating with a second protocol and comprising one or a plurality of antennas, wherein the first wireless network creates one or a plurality of points of zero radio frequency (RF) energy at the location of the one or at least one of the plurality of antennas.
