Based on LTE network technology, it implements wireless backhaul functionality, has good coverage and anti-interference capabilities, provides a reliable wireless link for the base station, ensures data transmission with other base stations or core networks, ensures the connectivity and collaborative working capabilities of the wireless network system, and meets the service requirements of the base station for wireless backhaul data and receiving control commands.

[0036] In one specific embodiment, the main control unit receives status feedback information from each module and generates corresponding control commands based on preset working strategies and real-time communication requirements. The main control unit includes a processor and storage devices. The processor can be an Intel Core i9-13900K, featuring 16 cores (8 performance cores + 8 efficiency cores), 24 threads, and a turbo frequency of up to 5.8GHz. Its powerful computing capabilities easily handle workloads such as managing multiple modules simultaneously, processing complex algorithms, and real-time data interaction, ensuring the main control unit can efficiently run the base station operating system and various control software, achieving refined management of the entire base station system.

[0037] Storage devices:

[0038] Memory: Equipped with Samsung DDR5 6400MHz 32GB memory modules, the high-frequency DDR5 memory provides extremely fast read and write speeds, and the large storage capacity can meet the data caching needs of the main control unit when handling multiple tasks (such as simultaneously monitoring the status of each module, executing control algorithms, storing temporary data, etc.), ensuring the smooth operation of the system.

It can quickly load and save the base station's operating system, configuration files, security policies and various applications, and has the advantages of strong shock resistance and high reliability, which helps to maintain the long-term stable working state of the main control unit.

[0040] In one specific embodiment, the power supply and heat dissipation module specifically includes a power supply module and a heat dissipation module;

[0041] The power module is responsible for providing power to all modules of the entire wireless base station;

[0042] Power adapter: Utilizing Mean Well's RSP-500-24 switching power supply, it features a wide input voltage range covering most global AC standards, a stable 24V DC output, and a maximum output power of 500W, capable of meeting the power requirements of multiple modules within the base station (such as antennas and control units).

[0046] A control panel developed by ROKOKO can be used. Its reconfigurable electromagnetic modules are fabricated using micro-nano processing technology, with individual unit sizes down to the millimeter level. This allows for continuous adjustment of the reflection phase and amplitude across a wide frequency range (e.g., 1-6 GHz). By applying different bias voltages to the reconfigurable electromagnetic modules, their electromagnetic characteristics can be altered, thus enabling flexible control of wireless signals. This panel can be customized in different sizes and shapes to suit various application scenarios, facilitating installation on building walls, poles, or other suitable locations around the base station. This allows for on-demand control of wireless signals, enhancing the base station's signal coverage.

[0047] In one specific embodiment, the control controller is closely connected to the main control unit and the control panel. Based on the control signal issued by the main control unit and the channel status obtained from the wireless communication module, the controller generates control commands for each reconfigurable electromagnetic module of the control panel and transmits the control commands to the control panel to drive the reconfigurable electromagnetic modules to complete the corresponding electromagnetic characteristic adjustment.

[0048] The control panel can utilize a combination of FPGA and microcontroller hardware platforms: Intel's Cyclone V-series FPGA paired with an external microcontroller (such as a Raspberry Pi 4B) forms the control panel. The Cyclone V-series FPGA has abundant logic resources and configurable I / O pins, allowing for the implementation of dedicated circuit functions for controlling the control panel through hardware description languages. Then, a microcontroller like the Raspberry Pi 4B is used for overall coordination and management, as well as communication with external modules (such as the main control unit and wireless communication modules). This enables dynamic control of the electromagnetic characteristics of the control panel, ensuring that it can work collaboratively with other modules in the base station system, effectively improving the wireless signal propagation path and coverage.
