Site Diversity TRIZ Cases
- Flexible Distributed MIMO Antenna Cable for Easier Large-Area Deployment
A flexible antenna cable integrates elements, power, and data links to simplify distributed massive MIMO installation while improving coverage.
- MIMO Sector Antenna Element Control for Back Lobe Interference
Dynamic antenna element adjustment cuts back lobe overlap between neighboring base stations, improving user equipment signal quality and throughput.
- Downlink Channel Sounding With Low-Overhead CoMP Beam Feedback
Multiple reference signals and compact CSI feedback help base stations choose beams and precoding while reducing CoMP and MIMO overhead.
- Coordinated WLAN Beam Width Selection for Spatial Reuse
Dynamic beam width selection lets coordinated APs reduce co-channel interference, include more STAs in CSR, and raise WLAN capacity.
- Ground-Based Beamforming for Low-Complexity Relay Satellites
Ground access nodes compute beam weights across relay paths, boosting satellite link capacity while reducing onboard complexity, weight, and power.
- Beamforming Frame Structure With Region-Specific Beam Change Timing
Frame regions use different beam change times and pilot patterns to improve beamformed wireless transmission efficiency and reception.
- Multi-Beam Reflector Array for NLOS Millimeter-Wave Range Extension
Active and passive reflectors create optimized NLOS millimeter-wave paths to extend RF range, improve coverage, and sustain throughput.
