【正文】 aspects Business considerations The unprecedented interest and investment in the next generation needs to be matched to viable business cases to ensure sustainability Six predictions for wireless broadband 2022 1. No new worldwide allocations of mmWave spectrum 2. Cellular will extend into the ISM band at 60 GHz (Unlicensed access) 3. The importance of UE antennas will finally be recognized 4. WLAN will bee an equal partner with cellular 5. Without technical breakthrough, the operator business case will not support a massive expansion in capacity 6. The success of will determine the likelihood of cellular at mmWave frequencies mmWave Antenna Development and Validation Antenna Performance Steerable: design, characterization (codebook), producibility Beam forming: Reciprocity, Gain/Phase/TDD elements Traceable Measurements Challenging without facility for conducted measurements Integrated Power: Varies with radiation pattern Receiver Sensitivity ? Interoperability with steerable antennas (MAC and PHY) ? Test Modes Start or Stop steering/beamforming Select test pattern Use testonly DUT configurations to simplify parametric measurements, and to aid in isolating performance issues of ind
