1Area of stationary object
If satellite systems are used for long-range communication, then coverage area is improved, but latency increases and reliability deteriorates
Solution Approach 1:
The patent segments the communication network into distributed ad-hoc nodes that communicate directly with each other rather than routing all traffic through a central satellite. This creates multiple independent communication paths, reducing latency by eliminating the long round-trip delay to geostationary orbit while maintaining wide coverage through the distributed network topology.
Solution Approach 2:
The patent introduces intermediate relay nodes (other mobile units or fixed base stations) that act as mediators to forward communications. Instead of direct satellite-to-terminal communication requiring motorized parabolic dishes, the system uses these intermediaries to establish stable links, reducing the need for complex tracking mechanisms and improving reliability.
2Productivity
If MIMO techniques are used to increase bandwidth efficiency, then data rate is improved, but device complexity increases
Solution Approach 1:
The patent applies beamforming techniques selectively based on mobility conditions. For high-speed mobile applications where channel changes rapidly, the system uses simpler single-antenna or reduced-MIMO configurations rather than full MIMO, avoiding the complexity overhead when it provides minimal benefit. The system adapts the level of spatial processing to match the actual channel dynamics.
Solution Approach 2:
The patent implements dynamic adaptation of MIMO configuration based on channel conditions and mobility speed. The system adjusts the number of active antenna elements and processing complexity in real-time, using full MIMO capabilities when channels are stable and reducing to simpler modes when channels change rapidly, thereby optimizing the trade-off between bandwidth efficiency and device complexity.
3Reliability
If highly directive antennas are used for satellite communication, then link stability is improved, but system complexity and cost increase
Solution Approach 1:
The patent implements self-organizing ad-hoc networks where mobile units automatically discover and establish connections with neighboring units without requiring complex centralized control or motorized antenna tracking. The distributed nodes autonomously manage beamforming and routing, eliminating the need for expensive gyro-stabilized parabolic dishes while maintaining link stability through cooperative processing.
Solution Approach 2:
The patent replaces mechanical antenna tracking systems (motorized parabolic dishes with gyro stabilization) with electronically steerable phased array antennas. This substitution eliminates moving parts and mechanical complexity while achieving the same or better beam steering capability through electronic phase control, significantly reducing system complexity and cost.
4Measurement precision
If GPS and sensor systems are combined for real-time guidance, then positioning accuracy is improved, but latency and complexity increase
Solution Approach 1:
The patent merges communication and positioning functions into a single integrated system. The same distributed ad-hoc network infrastructure used for communication also provides positioning through time-of-flight measurements and triangulation algorithms. This eliminates the need for separate GPS receivers and sensor fusion systems, reducing overall system complexity and latency while maintaining high positioning accuracy through the cooperative network.
Solution Approach 2:
The patent creates a universal distributed network that simultaneously provides communication, positioning, and navigation functions. The same network nodes and signal exchanges used for data transmission also enable precise positioning through embedded timing measurements, allowing the system to serve multiple purposes without requiring separate specialized subsystems.
