Description

Technical Field

[0001] This invention belongs to the field of wireless charging and wireless data communication technology, and particularly relates to a charging and communication device and method based on magnetic attraction mechanism and millimeter wave antenna. Background Technology

[0002] As mobile devices become increasingly feature-rich, users' demands for a wireless user experience are constantly rising. This requires devices to not only provide wireless charging but also high-speed wireless data transmission capabilities. However, existing technologies have the following limitations: First, existing magnetic wireless charging solutions suffer from bottlenecks in data transmission. Current mainstream magnetic wireless charging technologies primarily address the power alignment issue between the transmitter and receiver, improving coil coupling efficiency through magnetic force. However, these solutions do not integrate high-speed data channels. When performing data synchronization, screen mirroring, or backup, the terminal still relies on wireless communication technologies such as Wi-Fi, Bluetooth, or Ultra-Wideband (UWB). These wireless communication technologies are limited by the congested and heavily interfered 2.4 / 5GHz frequency bands, and suffer from problems such as high transmission latency, high power consumption, and low data rates.

[0003] Secondly, 60GHz millimeter-wave communication technology faces alignment challenges in mobile terminal applications. While 60GHz millimeter-wave modules can provide air interface rates exceeding 21.25Gb / s, making them an ideal high-speed data transmission solution, their short wavelength and small antenna aperture result in extremely stringent beam directivity requirements. To maintain a stable link, the transmitting and receiving ends typically need to maintain a pointing error of less than ±3°. In practical applications, uncontrollable factors such as user hand shake and random desktop placement can easily cause beam deviation, leading to frequent communication link drops or sudden speed reductions, severely impacting connection reliability and user experience.

[0004] Finally, current technologies lack a fusion architecture for mechanical positioning and beam alignment. Research has found that the mechanical alignment accuracy of existing magnetic wireless charging solutions typically reaches ±0.3mm / ±2°, which precisely meets the beamwidth margin requirements of 60GHz antenna arrays, providing a theoretical basis for fusion applications. However, no terminal architecture in the industry has yet integrated magnetic mechanical alignment with millimeter-wave beam alignment. In current designs, wireless charging systems and millimeter-wave communication systems are often independent, leading to redundant hardware costs, complex system architecture, and requiring users to handle power supply and data connection separately, resulting in a fragmented user experience and preventing seamless interaction for immediate connection upon placement. Summary of the Invention

[0005] To address the aforementioned issues, this invention proposes a charging and communication device and method based on magnetic traction mechanics and a millimeter-wave antenna. Magnetic traction alignment is achieved using a Halbach array permanent magnet, ensuring the receiving terminal is fixed to the charging end with an error controlled within ±0.3mm / ±2°. The data communication end meets the beam pointing requirement of a 60GHz millimeter-wave antenna array of ≤±3°, providing a user experience of instant connection and zero operational intervention. Through a three-level algorithm of positioning notification, handshake, and beam precision alignment, along with a millisecond-level realignment mechanism, a high-speed data link with a rate ≥10Gb / s is established, achieving zero-interruption recovery capability and low-latency transmission performance even when link quality monitoring indicators decline. Real-time monitoring of the magnetic field strength using a Hall sensor enables synchronous wake-up and sleep control of the wireless charging coil and the millimeter-wave communication module, achieving low-power standby performance. Effective suppression of eddy currents using a nanocrystalline magnetic shielding sheet achieves a wireless charging efficiency η≥80%, resulting in high-efficiency power supply performance.

[0006] A first aspect of the present invention provides a charging and communication device based on magnetic attraction mechanics and a millimeter-wave antenna, comprising: A charging end is used to fix the power receiving terminal and supply power to the power receiving terminal; A data communication terminal, used for data transmission between the power receiving terminal and the power supply terminal, is evenly distributed on the outside of the charging terminal; A charging and communication module includes a charging unit and a communication unit. The charging unit is used to receive DC power input from a power supply terminal and convert the DC power into alternating magnetic field energy, so that the charging terminal can supply power to the power receiving terminal. The communication unit is used for configuration and data transmission: demodulating the millimeter-wave signal received by the data communication terminal into a data signal and transmitting it to the power supply terminal, and modulating the data signal of the power supply terminal into a millimeter-wave signal and transmitting it through the data communication terminal.

[0007] Preferably, the charging terminal includes an inner ring coil and an outer ring assembly. The outer ring assembly surrounds the outer side of the inner ring coil and is used to provide magnetic attraction to fix the receiving terminal. The inner ring coil is used to generate an alternating magnetic field to power the receiving terminal and realize wireless charging.

[0008] Preferably, the outer ring component uses a Halbach array permanent magnet; the inner ring coil is a Qi standard wireless charging coil.

[0009] Preferably, the side of the inner loop coil furthest from the power receiving terminal uses a 0.1mm nanocrystalline magnetic shielding sheet to provide magnetic shielding, magnetization, and suppression of eddy current losses.

[0010] Preferably, the data communication terminal includes several millimeter-wave antennas, which are configured to receive millimeter-wave data signals in the 60GHz band or convert the data signals of the communication unit into millimeter-wave data signals in the 60GHz band and transmit them.

[0011] Preferably, the charging and communication module includes a Hall sensor, which is used to detect the magnetic field signal of the powered terminal and trigger the data communication terminal and the charging unit to switch between wake-up, working and sleep modes according to the strength of the magnetic field signal.

[0012] A second aspect of the present invention provides a charging and communication method based on magnetic attraction mechanics and a millimeter-wave antenna, applied to the charging and communication device based on magnetic attraction mechanics and a millimeter-wave antenna described in any one of the preceding claims, comprising: S100: By monitoring with a Hall sensor, when the magnetic field strength of the powered terminal is greater than a first preset value, the inner loop coil is driven by the charging and communication module to trigger the wake-up mode of the data communication terminal and the charging unit. S200: Under the magnetic attraction between the outer ring assembly and the power receiving terminal, the power receiving terminal is fixed in a preset position; S300: When the powered terminal is fixed in a preset position under the action of magnetic attraction, if the magnetic attraction is detected to be lower than the second preset value, the communication unit is triggered to perform a process including positioning notification, link handshake and beam alignment to achieve link construction at a rate of 10Gb / s. S400: Based on the power parameters of the powered terminal, boost charging is achieved through the inner loop coil; the link quality monitoring indicators of the powered terminal are obtained in real time through the communication unit, and beam realignment and communication link restoration are triggered based on the link quality monitoring indicators.

[0013] Preferably, the method further includes triggering the sleep mode of the data communication terminal and the charging unit. The specific steps are as follows: when the magnetic attraction force is lower than the third preset value, or when the signal that the receiving terminal has completed charging is obtained through the communication unit, the charging and communication module is driven to control the charging terminal and the data communication terminal to switch to sleep mode.

[0014] Preferably, triggering the communication unit to perform steps including location notification, handshake, and beam alignment further includes: The power supply terminal receives and transmits data with the charging and communication module via a USB interface; the USB interface is configured as a USB 2.0 interface or a USB 3.0 interface; the power receiving terminal receives and transmits millimeter-wave signals via a millimeter-wave antenna, realizing data interaction with the power supply terminal.

[0015] Preferably, if the number of millimeter-wave antennas is 1, the data communication terminal adopts a time-division multiplexing communication mode; If the number of millimeter-wave antennas is 2, the data communication end adopts a 1-transmit 1-receive simultaneous communication mode or a 2-transmit 2-receive time-division communication mode. If the number of millimeter-wave antennas is 3, the data communication terminal selects the 2 millimeter-wave antennas with the highest receiving strength and adopts a 1-transmit 1-receive simultaneous communication mode or a 2-transmit 2-receive time-division communication mode. If the number of millimeter-wave antennas is 4, the data communication terminal selects the millimeter-wave antenna with the highest receiving strength for time-division communication (1 transmit, 1 receive), or selects the two millimeter-wave antennas with the highest receiving strength for simultaneous communication (2 transmit, 2 receive).

[0016] Because the present invention adopts the above technical solution, it has the following advantages and positive effects compared with the prior art: 1. By using Halbach array permanent magnets to provide magnetic mechanical alignment, the position of the receiving terminal is fixed to the charging end, ensuring that the error is controlled within ±0.3mm / ±2°. The data communication end meets the beam pointing requirement of ≤±3° for 60GHz millimeter wave antenna array, achieving a user experience of instant connection and zero operation intervention.

[0017] 2. Through a three-level algorithm of location notification, handshake, and beam alignment, and a millisecond-level realignment mechanism, high-speed data link construction with a rate of ≥10Gb / s was achieved, and the link's zero-interruption recovery capability and low-latency transmission performance were obtained when the link quality monitoring indicators declined.

[0018] 3. By using a Hall sensor to monitor the magnetic field strength in real time, synchronous wake-up and sleep control of the wireless charging coil and the millimeter-wave communication module are achieved, resulting in low-power standby performance.

[0019] 4. By effectively suppressing eddy currents through nanocrystalline magnetic shielding sheets, wireless charging efficiency η≥80% was achieved, resulting in high-efficiency power supply performance. Attached Figure Description

[0020] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, wherein: Figure 1 This is a front view of the charging and communication device based on magnetic attraction mechanism and millimeter-wave antenna in this invention; Figure 2 This is a top view of the charging and communication device based on magnetic attraction mechanism and millimeter-wave antenna in this invention; Figure 3 This is a flowchart of the charging and communication method in this invention.

[0021] Explanation of reference numerals in the attached figures: 1: Charging end; 101: Inner loop coil; 102: Outer loop assembly; 201: Millimeter wave antenna; 3: Charging and communication module; 301: Hall sensor. Detailed Implementation

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become clearer from the following description and claims. It should be noted that the drawings are all in a very simplified form and use non-precise ratios, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0023] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0024] First Embodiment See Figure 1 The first aspect of the present invention provides a charging and communication device based on magnetic attraction mechanism and millimeter-wave antenna 201, comprising: Charging end 1 is used to fix the receiving terminal and supply power to the receiving terminal; The data communication terminal, used for data transmission between the power receiving terminal and the power supply terminal, is evenly distributed on the outside of the charging terminal 1; The charging and communication module 3 includes a charging unit and a communication unit. The charging unit is used to receive DC power input from the power supply terminal and convert DC power into alternating magnetic field energy, so that the charging terminal 1 can supply power to the power receiving terminal. The communication unit is used for configuration and data transmission: demodulating the millimeter wave signal received by the data communication terminal into a data signal and transmitting it to the power supply terminal, and modulating the data signal of the power supply terminal into a millimeter wave signal and transmitting it through the data communication terminal.

[0025] The design achieves dual automatic alignment—mechanical and beam alignment—through the charging end. The charging end's magnetic positioning function secures the receiving terminal, while the data communication terminals are evenly distributed around the charging end. This ensures that the millimeter-wave antenna array automatically achieves the required pointing accuracy upon magnetic alignment. This design delivers a user experience with zero additional movement. By surrounding the charging end with the data communication terminals, a coplanar layout of the coil and antenna is achieved, avoiding the increased thickness caused by vertical stacking. The overall thickness increase is less than 0.8mm, compatibility with existing smartphone and laptop industrial design requirements, and a lower integration threshold. The communication unit configures the transmission and reception of millimeter-wave signals, establishing a high-speed data channel independent of the charging magnetic field. This feature avoids congestion in the 2.4 / 5GHz band, resulting in an air interface latency improvement of less than 0.5ms, thus supporting high-bandwidth applications such as 4K / 60Hz lossless projection.

[0026] Taking a smartphone back clip solution as an example, the charging end includes an inner ring coil and an outer ring assembly, employing an integrated structure of the inner ring coil, millimeter-wave antenna, and outer ring assembly, with a thickness of approximately 0.9mm. The outer ring assembly provides magnetic attraction to secure the smartphone as the receiving terminal, while the inner ring coil supplies power to the smartphone. The data communication end includes several millimeter-wave antennas evenly distributed on the outer side of the charging end. The charging and communication module is integrated inside the back clip, including a charging unit and a communication unit. The charging unit receives external DC power and converts it into alternating magnetic field energy; the communication unit configures the modulation and demodulation of the millimeter-wave signal. Actual test results: When the fixed position of the receiving terminal is offset by 0.2mm from the outer ring assembly of the device, the charging end, in conjunction with the nanocrystalline magnetic shielding sheet, achieves a charging efficiency η=82%; the data communication end and communication unit work together to achieve a millimeter-wave rate of 2.3Gb / s and RSSI=-38dBm, verifying that efficient charging and stable communication can be maintained even with a small offset.

[0027] Taking another example, a vehicle armrest box expansion dock solution integrates charging and communication devices into the bottom of the vehicle armrest box. The charging end is configured as a TXPad, whose outer ring component provides a horizontal magnetic force of up to 12N to securely hold the laptop as the receiving terminal. The data communication end includes several millimeter-wave antennas evenly distributed outside the charging area of ​​the TXPad. The charging and communication modules include a charging unit and a communication unit. The charging unit supports 15W or 25W wireless charging power output; the communication unit is configured to establish a 60GHz millimeter-wave communication link. The specific working process is as follows: the laptop is placed at the bottom of the armrest box and automatically aligned and fixed under magnetic attraction. The charging unit supplies power to the laptop through the charging end; the communication unit modulates the data signal into a millimeter-wave signal and transmits it through the data communication end to achieve data transmission. Actual test results: the laptop aligns immediately upon placement, requiring no manual adjustment. While wirelessly charging at 15W or 25W, a 60GHz link rate of 4.6Gb / s is maintained, achieving synchronous charging and data transmission, and enabling data communication between the power supply terminal and the receiving terminal.

[0028] See Figure 2 Preferably, the charging terminal 1 includes an inner ring coil 101 and an outer ring assembly 102. The outer ring assembly 102 surrounds the outer side of the inner ring coil 101. The outer ring assembly 102 is used to provide magnetic attraction to fix the receiving terminal. The inner ring coil 101 is used to generate an alternating magnetic field to power the receiving terminal and realize wireless charging.

[0029] The magnetic attraction provided by the outer ring assembly drives the receiving terminal to move and fix it, automatically keeping the receiving coil of the receiving terminal concentrically aligned with the inner ring coil. This solves the problem of decreased coupling coefficient caused by positional misalignment in wireless charging, ensuring that charging efficiency remains high at all times. The distribution structure of the outer ring magnet and inner ring coil makes efficient use of the device's surface area. The outer ring assembly, located on the outside, provides strong magnetic attraction while avoiding the electromagnetic field center region of the inner ring coil, preventing permanent magnet materials from hindering coil flux transmission or generating eddy current losses. This achieves structural synergy between mechanical fixation and wireless charging functions. The surrounding design of the outer ring assembly increases the magnetic contact area, providing a stable and uniform horizontal magnetic attraction force, making it less prone to misalignment or detachment of the receiving terminal during charging or data transmission due to external factors, ensuring a relatively stable relative position between the receiving terminal and the device.

[0030] Preferably, the outer ring component 102 uses a Halbach array permanent magnet; the inner ring coil 101 is a Qi standard wireless charging coil.

[0031] By employing Halbach array permanent magnets, a magnetic attraction force is generated on the side facing the receiving terminal. This provides a horizontal force greater than 800N to the receiving terminal, ensuring it is firmly attached to a preset position. The magnetic attraction guides high-precision automatic alignment with an error of less than or equal to ±0.3mm, providing a mechanical basis for subsequent millimeter-wave beam alignment. Using a Qi-compliant wireless charging coil, the device is compatible with Qi-compliant smartphones and electronic devices, enabling basic charging without a dedicated receiver, lowering the barrier to entry for users. Furthermore, the use of mature protocols ensures the safety and stability of the charging process.

[0032] Preferably, the side of the inner ring coil 101 furthest from the power receiving terminal is equipped with a 0.1mm nanocrystalline magnetic shielding sheet for magnetic shielding, magnetic concentration and suppression of eddy current loss.

[0033] By placing a nanocrystalline magnetic shielding sheet on the side furthest from the receiving terminal, the high permeability of the nanocrystalline material serves as both magnetic shielding and magnetic focusing. It effectively blocks and reflects the alternating magnetic field generated by the inner coil to the receiving terminal, increasing the magnetic flux coupling coefficient between the transmitting and receiving coils, thereby improving the transmission efficiency of wireless charging. The 0.1mm nanocrystalline magnetic shielding sheet prevents the magnetic field from diffusing into the internal metal components of the device, suppressing eddy current losses generated within the metal. This reduces unnecessary energy waste, avoids internal heating caused by eddy currents, and ensures the stability and safety of the device operation. Using 0.1mm thick nanocrystalline material achieves an extremely thin profile while maintaining magnetic shielding performance. This overcomes the shortcomings of traditional ferrite magnetic shielding sheets, which are thick and fragile, reducing the overall module thickness and achieving a slim design with an overall device thickness increase of less than 0.8mm.

[0034] See Figure 1 and Figure 2 Preferably, the data communication terminal includes a plurality of millimeter-wave antennas 201, which are configured to receive millimeter-wave data signals in the 60GHz band or convert the data signals of the communication unit into millimeter-wave data signals in the 60GHz band and transmit them.

[0035] Leveraging the wide bandwidth of the 60GHz band, this device overcomes the bandwidth limitations of the traditional 2.4 / 5GHz bands, supporting ultra-high-speed data transmission of 10Gb / s or higher. This meets the demands of high-bandwidth scenarios such as lossless 4K / 60Hz projection, real-time AR / VR interaction, and instant large file transfer. The 60GHz band is independent of the congested Wi-Fi / Bluetooth (2.4 / 5GHz) public bands, effectively avoiding co-channel interference in home or office environments and ensuring the stability of the communication link. Simultaneously, the millimeter-wave band achieves an air interface latency of less than 0.5ms, guaranteeing real-time data interaction. By configuring the transceiver function of the millimeter-wave antenna, the device establishes a high-speed data transmission channel while providing wireless charging. This frees users from the constraints of charging cables and data cables, truly achieving a cable-free, one-stop power supply and data synchronization experience.

[0036] Preferably, the charging and communication module 3 includes a Hall sensor 301, which is used to detect the magnetic field signal of the powered terminal and trigger the switching of wake-up, working and sleep modes between the data communication terminal and the charging unit according to the strength of the magnetic field signal.

[0037] By detecting magnetic field signals using a Hall effect sensor, the system can detect the proximity and adsorption status of the powered terminal. This feature enables instant connection and automatic wake-up control logic, eliminating the need for any additional manual operation by the user and improving ease of use. Using the Hall effect sensor as a trigger source, data communication is only initiated when a valid magnetic connection is detected, avoiding prolonged searching and standby of the high-frequency communication module in idle states, thus effectively extending the battery life of both the power supply terminal and the device itself. The Hall effect sensor detecting a magnetic field signal means that the powered terminal has completed mechanical positioning through magnetic attraction. Using this as a trigger condition to initiate communication ensures that the millimeter-wave link is built on precise mechanical alignment, avoiding link establishment failures or resource waste caused by blindly initiating invalid connections due to misalignment of the powered terminal.

[0038] Second Embodiment See Figure 3 A second aspect of the present invention provides a charging and communication method based on magnetic attraction mechanics and a millimeter-wave antenna, applicable to any of the charging and communication devices based on magnetic attraction mechanics and millimeter-wave antennas described above, comprising: S100: When the magnetic field strength of the powered terminal is greater than the first preset value, the inner loop coil 101 is driven by the charging and communication module 3 to trigger the wake-up mode of the data communication terminal and the charging unit, as monitored by the Hall sensor 301. S200: Under the magnetic attraction between the outer ring component 102 and the power receiving terminal, the power receiving terminal is fixed in a preset position; S300: When the powered terminal is fixed in a preset position under the action of magnetic attraction, the monitoring magnetic attraction force is lower than the second preset value, triggering the communication unit to perform a process including positioning notification, link handshake and beam alignment, so as to achieve the construction of a link with a rate of 10Gb / s. S400: Based on the power parameters of the powered terminal, boost charging is achieved through the inner loop coil 101; the link quality monitoring indicators of the powered terminal are obtained in real time through the communication unit, and beam realignment and communication link restoration are triggered based on the link quality monitoring indicators.

[0039] By setting two preset thresholds (first and second), the workflow is divided into two stages: proximity wake-up (beacon mode) and magnetic connection. This hierarchical response mechanism avoids the device remaining in full-power standby mode for extended periods without a target. It only activates a low-power beacon when a terminal is detected approaching, and then initiates high-power, high-speed communication after confirming precise magnetic connection, thus reducing overall system energy consumption. A magnetic force exceeding the second preset value is used as a prerequisite for triggering beam alignment. This logic ensures that the millimeter-wave link is built upon precise mechanical alignment, eliminating communication blind spots or connection failures caused by misalignment and guaranteeing the success rate and stability of 10Gb / s link establishment. During charging and communication, a dynamic beam realignment mechanism based on link quality monitoring indicators is introduced. When the powered terminal experiences slight displacement or rotation leading to signal attenuation, the system automatically triggers beam realignment and recovery, effectively solving the problem of millimeter-wave communication interruptions due to position changes and achieving continuous and stable high-speed data transmission in wireless charging scenarios. In this embodiment, 30mT is used for the first threshold and 3N is used for the second threshold. Other values ​​can also be used for the first and second thresholds, and this embodiment does not impose any restrictions.

[0040] Preferably, it also includes triggering the sleep mode of the data communication terminal and the charging unit. The specific steps are as follows: when the magnetic attraction force is lower than the third preset value, or when the signal that the receiving terminal has completed charging is obtained through the communication unit, the charging and communication module 3 is driven to control the charging terminal 1 and the data communication terminal to switch to sleep mode.

[0041] By monitoring the magnetic field strength to below a threshold or acquiring a charging completion signal, the system automatically identifies the end-of-work status and simultaneously controls the charging coil and the high-power millimeter-wave communication module to enter sleep mode. This avoids the device maintaining high-power operation when there is no device connection or after the task is completed, saving energy. When the magnetic attraction force is below a third preset value, the energy emission and data transmission functions are cut off. This not only prevents ineffective radiation from the charging coil in an unloaded state but also avoids the risk of eddy current overheating that may be caused by foreign metal objects accidentally entering the charging area, ensuring safe use. This implementation uses ON for the third preset value, but other values ​​can also be used; this embodiment is not limited. Combined with the aforementioned wake-up and workflow, this step completes the control closed loop of proximity wake-up, work processing, work completion, and sleep mode. Whether physically removed (or logically completed), automatic reset can be achieved without manual intervention, improving the integrity and convenience of the user experience.

[0042] Preferably, triggering the communication unit to perform steps including location notification, handshake, and beam alignment further includes: The power supply terminal receives and transmits data with the charging and communication module 3 via a USB interface; the USB interface is configured as either a USB 2.0 interface or a USB 3.0 interface; the power receiving terminal receives and transmits millimeter-wave signals via a millimeter-wave antenna 201, enabling data interaction with the power supply terminal.

[0043] By converting the data stream from the standard USB interface (USB 2.0 / 3.0) on the power supply side into a 60GHz millimeter-wave wireless signal, the powered terminal can seamlessly connect wirelessly to the power supply terminal (such as a PC, vehicle head unit, or power adapter), allowing users to enjoy wired-level speeds while freeing them from the constraints of cables. With a universal USB 2.0 or USB 3.0 interface, the device is directly compatible with the vast majority of laptops, vehicle infotainment systems, and smart terminals on the market, eliminating the need for custom proprietary protocol interfaces or additional wireless network cards on the host side. This lowers the barrier to entry and reduces hardware modification costs, enhancing the product's versatility.

[0044] Preferably, if the number of millimeter-wave antennas 201 is 1, the data communication terminal adopts a time-division multiplexing communication mode; If the number of millimeter-wave antennas 201 is 2, the data communication terminal adopts a 1-transmit 1-receive simultaneous communication mode or a 2-transmit 2-receive time-division communication mode. If the number of millimeter-wave antennas 201 is 3, the data communication terminal selects the two millimeter-wave antennas 201 with the highest receiving strength and adopts a 1-transmit 1-receive simultaneous communication mode or a 2-transmit 2-receive time-division communication mode. If the number of millimeter-wave antennas 201 is 4, the data communication terminal selects the millimeter-wave antenna 201 with the highest receiving strength for time-division communication (1 transmit, 1 receive), or selects the two millimeter-wave antennas 201 with the highest receiving strength for simultaneous communication (2 transmit, 2 receive).

[0045] This logic automatically matches the optimal communication operating mode (time-division or simultaneous) based on the number of millimeter-wave antennas. The scalable architecture design enables the product to cover different market needs: ensuring basic functions in a low-cost single-antenna solution, and unleashing high performance in a multi-antenna solution, allowing for differentiated product deployment without changing the core control logic.
