Abstract: Various embodiments provide for systems and methods for wireless communications that implement transmitter protection schemes using spatial combining. The protection scheme implemented by some embodiments provides for a number of benefits, including without limitation: hitless protection; constant power monitoring for each wireless channel being utilized; extra gain to wireless signals transmitted; beam steering, beam hopping, and beam alignment capabilities; and varying levels of transmission path protection (e.g., 1+1 protection, or 1+N protection). Additionally, the features of some embodiments may be applied to a variety of wireless communications systems including, for example, microwave wireless systems, cellular phone systems and WiFi systems.

Abstract: Systems and methods for combining signals from multiple active wireless transmitters are discussed herein. An exemplary system comprises a radio enclosure, a first transmitting RFU, a second transmitting RFU, and a combiner. The first transmitting RFU may be configured to receive a signal, upconvert the signal, compare a phase of the upconverted signal to a predetermined phase value, and adjust the phase of the signal based on the comparison to provide a first phase-adjusted upconverted signal. The second transmitting RFU may be configured to receive the signal, upconvert the signal, compare a phase of the upconverted signal to the predetermined phase value, and adjust the phase of the signal based on the comparison to provide a second phase-adjusted upconverted signal. The coupler may be configured to combine the first and second phase-adjusted upconverted signals to create an output signal and provide the output signal to an antenna for transmission.

Abstract: Various embodiments are directed toward systems and method for manufacturing low cost passive waveguide components. For example, various embodiments relate to low cost manufacturing of passive waveguide components, including without limitation, waveguide filters, waveguide diplexers, waveguide multiplexers, waveguide bends, waveguide transitions, waveguide spacers, and antenna adapters. Some embodiments comprise manufacturing a passive waveguide component by creating a non-conductive structure using a low cost fabrication technology, such as injection molding or three-dimensional (3D) printing, and then forming a conductive layer over the non-conductive structure such that the conductive layer creates an electrical feature of the passive waveguide component.
