1Area of stationary object
If omni-directional antennas are used for wireless communication between modules, then communication coverage is improved, but interference between modules increases and data transmission efficiency decreases
Solution Approach 1:
The patent applies beamforming technology to create directional radiation patterns that concentrate communication energy toward specific target modules rather than radiating uniformly in all directions. This localizes the communication coverage to specific spatial regions, reducing interference with other module pairs while maintaining adequate coverage for the intended communication path.
Solution Approach 2:
The system dynamically adjusts the radiation pattern directions and beamforming weights based on real-time identification of target modules and their spatial positions. The radiation patterns can be reconfigured on-the-fly to track and communicate with different modules as they are identified or as spatial relationships change during the survey operation.
2Adaptability or versatility
If omni-directional antennas are used, then all directions are covered, but power consumption increases due to radiation in all directions
Solution Approach 1:
The beamforming technology concentrates transmitted power into focused directional beams toward specific target modules rather than radiating energy uniformly in all directions. This localized energy transmission maintains adaptability to communicate with any module while significantly reducing total power consumption by eliminating radiation into unused spatial regions.
Solution Approach 2:
The system changes the radiation pattern parameters (direction, width, intensity) dynamically based on the identified target module's position and requirements. By adjusting these parameters on-the-fly, the antenna maintains versatility to communicate with any module while optimizing power efficiency for each specific communication scenario.
3Measurement precision
If physical adjustment of antennas is required for directionalization, then transmission precision is improved, but ease of operation decreases and deployment complexity increases
Solution Approach 1:
The patent replaces mechanical physical adjustment of antenna orientation with electronic beamforming control. Instead of physically rotating or repositioning antennas to achieve precise directional transmission, the system uses electronic signal processing to dynamically steer and focus radiation patterns toward target modules, achieving high directional precision without mechanical complexity.
Solution Approach 2:
The system performs automatic identification of target modules and self-configures the beamforming parameters to achieve optimal directional transmission. The modules autonomously identify each other and adjust their radiation patterns without requiring manual intervention for positioning or alignment, greatly simplifying deployment operations while maintaining high transmission precision.

AI summary
Apparatuses, systems, and methods for use of directionalized antennas at a seismic module in a seismic survey array. The directionalized antenna may be selectively controlled such that the control of the transmission functionality and reception functionality are independently controlled to transmit data in and receive data from different directions. In turn, bandwidth utilization may be improved in the survey. Additionally, the directionalized antennas may allow for simultaneous transmission and reception of data in a serial data transfer line.
