1Area of stationary object
If a conventional repeater device is installed to extend wireless signal range, then the coverage area is improved, but interference with existing airwaves and degradation of overall cellular network quality occurs
Solution Approach 1:
The repeater device is divided into multiple antenna elements that can be independently controlled and steered. This segmentation allows the system to direct signals specifically toward intended receivers while minimizing omnidirectional interference, thereby extending coverage without degrading overall network quality.
Solution Approach 2:
The system implements beamforming to create localized high-gain signal regions directed at specific users or areas. By concentrating signal energy where needed rather than broadcasting uniformly, the repeater extends coverage in targeted directions while reducing interference in other directions, thus improving coverage area without proportionally increasing harmful interference.
2Reliability
If a conventional repeater device is used to improve weak signals, then signal strength at specific installation sites is improved, but resources are shared among multiple users resulting in reduced dedicated performance
Solution Approach 1:
The repeater device dynamically adjusts beam directions, gains, and resource allocation based on real-time channel conditions and user requirements. This dynamic adaptation allows the system to provide strong signals to multiple users while allocating dedicated resources to specific users when needed, thereby maintaining signal strength improvements while enabling high dedicated data transfer rates through adaptive resource management.
3Object-generated harmful factors
If a repeater device operates in slave mode with network time synchronization, then interference with existing airwaves is reduced, but the device complexity increases due to synchronization requirements
Solution Approach 1:
The repeater device implements a feedback-based synchronization mechanism where it continuously monitors timing signals from the base station, compares its own transmission timing, and adjusts its operation accordingly. This feedback loop enables automatic network time synchronization that reduces interference by ensuring proper timing alignment with the cellular network, while the automated nature of the feedback mechanism keeps the implementation complexity manageable.

AI summary
A repeater device includes control circuitry that receives an operating mode change signal from a first wireless communication device and executes a pairing to establish a wireless connection with the first wireless communication device. The operating mode change signal is received before establishing the wireless connection. The control circuitry changes an operating mode from a first operating mode to a second operating mode based on the received signal. The second operating mode is a slave mode. The control circuitry activates the slave mode, and executes, based on activation of the slave mode, a synchronization with a modem of the first wireless communication device. The repeater device in the slave mode follows radio signals and a radio state of the modem of the first wireless communication device.
