Description

Technical Field

[0001] This utility model relates to the field of wireless transmission technology, and in particular to a wireless camera. Background Technology

[0002] Wireless cameras rely on wireless signals for data transmission, making them susceptible to interference from other wireless devices, which can degrade image and video quality. The signal stability of wireless cameras may be affected, especially in environments with complex electromagnetic conditions (such as city centers or large conference rooms).

[0003] Meanwhile, compared to WiFi 6, WiFi 7 features multi-link technology, enhanced MU-MIMO, and multi-AP collaboration. These technologies enable WiFi 7 to provide higher data transmission rates, lower latency, and better anti-interference capabilities, resulting in better performance in complex situations. This effectively addresses the aforementioned issues with wireless cameras.

[0004] By introducing technologies such as Multi-Link Operation (MLO), WiFi 7 can use multiple frequency bands simultaneously to transmit data, reducing latency. However, while MLO technology increases throughput by aggregating resources from multiple frequency bands, traditional wireless cameras are equipped with only one or a few antennas, making it impossible to transmit a large number of data streams simultaneously on the same frequency band. Furthermore, traditional wireless cameras typically only support a limited number of frequency bands and lack a structure capable of simultaneously connecting to and utilizing multiple frequency bands for data transmission. Therefore, a WiFi 7 wireless camera with multi-band support and a multi-antenna architecture is needed. Utility Model Content

[0034] To address the above problems, this utility model proposes a wireless camera, such as... Figure 1 and Figure 2 As shown, it includes controller 01 and WiFi module 02;

[0035] Controller 01 is electrically connected to WiFi module 02;

[0036] WiFi module 02 includes WiFi 7 baseband chip 21 and antenna architecture 22. Controller 01 is electrically connected to antenna architecture 22 through WiFi 7 baseband chip 21.

[0037] WiFi7 baseband chip 21 is used to convert digital signals to be transmitted into WiFi signals for antenna architecture 22 to transmit or to convert WiFi signals received by antenna architecture 22 into digital signals.

[0038] The antenna architecture 22 includes multiple antennas and is used to simultaneously transmit and / or receive WiFi signals in multiple frequency bands.

[0039] More specifically, WiFi 7 is the next-generation Wi-Fi standard, namely 802.11BE, also known as 802.11EHT, as defined by the IEEE protocol. Compared to WiFi 6, it introduces technologies such as 320MHz bandwidth, 4096-QAM, Multi-RU, multi-link, enhanced MU-MIMO, and multi-AP cooperation. As a result, WiFi 7 will provide higher data transmission rates and lower latency, better anti-interference capabilities, and better performance in complex situations compared to WiFi 6.

[0040] Traditional wireless cameras are equipped with only one or a few antennas, making it impossible to transmit multiple data streams simultaneously on the same frequency band. Furthermore, traditional wireless cameras typically only support a limited number of frequency bands and lack the structure to simultaneously connect to and utilize multiple frequency bands for data transmission. Therefore, existing wireless transmission cameras technically employ various unconventional wireless transmission protocols and modify relevant indicators in conventional solutions to meet the needs of specific application scenarios. These modifications usually involve communication protocols, spectrum, power, and other aspects, resulting in relatively complex technical implementation and higher costs.

[0041] Therefore, this utility model proposes a wireless camera, including a controller 01 and a WiFi module 02.

[0042] Controller 01 is electrically connected to WiFi module 02. Controller 01 is responsible for the overall control of the camera, including the coordination of image acquisition, processing, and transmission functions. It includes image processing algorithms to improve image quality or achieve specific image processing functions. It receives control commands from external devices and adjusts the camera's working status accordingly. WiFi module 02 transmits the data acquired by the camera to external devices via a wireless network.

[0043] The WiFi module 02 includes a WiFi 7 baseband chip 21 and an antenna architecture 22. The controller 01 is electrically connected to the antenna architecture 22 through the WiFi 7 baseband chip 21. The WiFi 7 baseband chip 21 is used to convert digital signals to be transmitted into WiFi signals for the antenna architecture 22 to transmit, or to convert WiFi signals received by the antenna architecture 22 into digital signals.

[0044] The WiFi 7 baseband chip 21 is the core component of the WiFi module 02. It is responsible for converting the digital signals sent by the controller 01 into WiFi signals for transmission by the antenna architecture 22. Simultaneously, it can also convert the WiFi signals received by the antenna architecture 22 into digital signals for processing by the controller 01. The WiFi 7 baseband chip 21 supports the latest WiFi 7 standard, offering higher data transmission rates, lower latency, and enhanced stability. Furthermore, it supports technologies such as multi-band aggregation, enabling full utilization of spectrum resources and improving communication efficiency.

[0045] like Figure 4 As shown, WiFi 7's MLO (Multi-Link Operation) band aggregation technology allows devices to connect to multiple frequency bands simultaneously and improves overall throughput through band aggregation. MLO technology can significantly increase data transmission rates through this aggregation. During multi-band aggregation, if a certain frequency band experiences interference or heavy load, MLO technology can automatically switch to other frequency bands for transmission.

[0046] Antenna architecture 22 includes multiple antennas and is used to simultaneously transmit and / or receive WiFi signals across multiple frequency bands. Antenna architecture 22 serves as the interface between WiFi module 02 and external wireless communication, responsible for simultaneously transmitting and / or receiving WiFi signals across multiple frequency bands. To meet the requirements of the WiFi 7 standard for multi-band operation, high transmission rates, and stability, antenna architecture 22 typically employs a multi-antenna design (such as MIMO technology) to support advanced features such as spatial multiplexing and beamforming. Furthermore, antenna architecture 22 also needs to have a wide frequency band coverage range to support multiple frequency bands in the WiFi 7 standard (such as 2.4GHz, 5GHz, and 6GHz).

[0047] Compared to single-antenna or dual-antenna architectures, the multi-antenna architecture 22 offers stronger spatial multiplexing capabilities, allowing for the simultaneous transmission of more data streams within the same frequency band, thereby improving spectral efficiency. More antennas translate to stronger signal coverage and higher signal stability. In complex environments, the multi-antenna architecture 22 is better able to handle signal fading and interference, ensuring the continuity and reliability of data transmission.

[0048] The combination of the multi-antenna architecture 22 and MLO technology can significantly improve the capacity of wireless communication systems, supporting more device connections and higher data transmission rates simultaneously. Through the synergistic effect of the multi-antenna architecture 22 and MLO technology, network performance can be optimized, latency and jitter reduced, and the stability and reliability of data transmission improved.

[0049] When controller 01 needs to send data, it first sends a digital signal to WiFi 7 baseband chip 21. WiFi 7 baseband chip 21 converts the digital signal into a WiFi signal and sends it out through antenna architecture 22. When an external device receives the WiFi signal, it converts it back into a digital signal for processing. Similarly, when an external device sends data to WiFi 7 baseband chip 21 through antenna architecture 22, WiFi 7 baseband chip 21 converts the received WiFi signal back into a digital signal and sends it to controller 01 for processing.

[0050] The WiFi module 02 of this utility model includes a WiFi7 baseband chip 21 and an antenna architecture 22. The antenna architecture 22 can simultaneously transmit and / or receive WiFi signals of multiple frequency bands. The antenna architecture 22 can support the inter-band aggregation function of WiFi7, which can significantly improve the throughput of data transmission, enhance anti-interference ability, and reduce latency.

[0051] In one embodiment, such as Figure 2 and Figure 3As shown, a single controller 01 is electrically connected to an AP terminal consisting of a single WiFi module 02, or a single controller 01 is electrically connected to a single WiFi module 02 to form a camera wireless terminal. Each camera wireless terminal is electrically connected to the same AP terminal consisting of a WiFi module 02.

[0052] An AP, short for Access Point, is a device that converts wired network signals into WiFi wireless signals for other devices to connect to. In AP mode, the wireless bridge acts as a WiFi sharing point, allowing devices such as mobile phones, laptops, and tablets to access the wireless signal. The AP primarily performs the following functions: amplifying the wireless signal between two wireless points, thus widening the AP's coverage area; connecting two endpoints to enable data transmission between the two APs; and treating all working APs as wireless clients by the router or main AP in this mode, enabling one-to-many connections and facilitating subnetwork management.

[0053] In the configuration where a single controller 01 is electrically connected to a single WiFi module 02 to form an access point (AP), the controller 01 and the WiFi module 02 are directly connected to each other, together forming an AP. The controller 01 connects to the network and obtains internet access through the AP.

[0054] In a controller 01 electrically connected to a single WiFi module 02, forming a camera wireless terminal, each camera wireless terminal is electrically connected to the same AP terminal composed of WiFi modules 02. The AP terminal is responsible for providing wireless network services, allowing cameras to connect to the network via WiFi. The camera wireless terminal and the WiFi 7-enabled AP terminal are connected using MLO technology, which allows connection to different frequency bands, thereby reducing interference and improving frequency band utilization efficiency. The camera wireless terminal can be deployed in large venues. With WiFi 7 support, only the connection to the AP terminal is needed to obtain the real-time transmitted image from the camera wireless terminal.

[0055] In one embodiment, the controller 01 is electrically connected to the WiFi module 02 via a PCIe interface. The controller 01 establishes this electrical connection with the WiFi module 02 via a PCIe interface, a connection typically achieved using a PCIe slot and a PCIe card. The PCIe interface provides a high-speed data transmission channel, enabling very fast data transmission between the controller 01 and the WiFi module 02.

[0056] Meanwhile, the PCIe interface boasts excellent signal stability, ensuring stable communication between the controller 01 and the WiFi module 02. This helps reduce errors and data loss during data transmission, improving the overall reliability of the system. Furthermore, the PCIe interface offers broad compatibility, supporting various models of the WiFi module 02 to meet diverse application scenarios and requirements.

[0057] In one embodiment, the antenna architecture 22 includes a power amplifier and a combiner, the power amplifier being electrically connected to the combiner and the combiner being electrically connected to the antenna;

[0058] A power amplifier is used to amplify WiFi signals; its main function is to amplify WiFi signals. In WiFi communication, because signals attenuate during transmission, they need to be amplified at the transmitting end to ensure that the signal can cover the predetermined transmission distance and achieve sufficient reception strength.

[0059] A combiner is used to combine multiple WiFi signals onto the output port of a single antenna. In wireless communication systems, combiners effectively improve spectrum utilization, reduce signal interference, and enable simultaneous communication by multiple users. It can combine signals of different frequencies or the same frequency but independent signals into a single signal for transmission.

[0060] In one embodiment, the antenna is a dual-band antenna; the dual-band antenna is used to receive and transmit WiFi signals on two different frequency bands. The antenna is used to receive and transmit wireless WiFi signals. It converts electrical signals into electromagnetic waves, which are then propagated through the air to the receiving end, or converts the received electromagnetic waves back into electrical signals for processing.

[0061] A dual-band antenna is a type of antenna that, with a relatively constant antenna size, can simultaneously meet system requirements within two different operating frequency bands. By supporting two frequency bands simultaneously, dual-band antennas can utilize spectrum resources more effectively, improving the capacity and efficiency of communication systems. In different scenarios, dual-band antennas can select the optimal frequency band for communication as needed, thereby enhancing network coverage and performance.

[0062] In one embodiment, three power amplifiers, three combiners, and three antennas are provided. Each power amplifier is electrically connected to two combiners, and each combiner is electrically connected to two power amplifiers. Each power combiner is electrically connected to one antenna, and each antenna is electrically connected to one combiner. Each power amplifier amplifies a wireless signal in one operating frequency band. The three combiners then combine the wireless signals amplified by the three power amplifiers in pairs and transmit them to one antenna, preferably a dual-band antenna, to transmit the combined wireless signals from two operating frequency bands or to receive wireless signals from two operating frequency bands.

[0063] In one embodiment, the antenna architecture 22 is used to simultaneously transmit and / or receive WiFi signals in three frequency bands: 2.4G, 5G, and 6G. The above embodiment describes the antenna architecture 22 as having three power amplifiers, three combiners, and three antennas.

[0064] The combiners include 2.4G+5G combiners, 2.4G+6G combiners, and 5G+6G combiners. The antennas include 2.4G & 5G dual-band antennas, 2.4G+6G dual-band antennas, and 5G+6G dual-band antennas. For the 2.4G & 5G dual-band antennas: First, three power amplifiers amplify the WiFi signals from the 2.4G, 5G, and 6G bands respectively. Then, the 2.4G+5G combiner combines the amplified 2.4G and 5G signals and transmits them to the 2.4G & 5G dual-band antenna, which then transmits them. Similarly, the remaining combiners operate in the same manner as the antennas.

[0065] The three different antennas can cover the three key WiFi frequency bands of 2.4GHz, 5GHz, and 6GHz, meeting the needs of future communication systems. Furthermore, each antenna is a dual-band antenna, allowing the selection of different frequency bands for communication based on actual requirements. This improves the flexibility and adaptability of the communication system, providing stable gain and directivity across different frequency bands, ensuring signal quality and reliability.

[0066] In one embodiment, the wireless camera further includes a lens assembly and a power supply assembly, the lens assembly and the power supply assembly being electrically connected to a controller 01;

[0067] The lens assembly is used to capture video images; it is responsible for capturing video images. It converts the captured light into electrical signals, providing raw material for subsequent image processing and transmission. The controller 01 processes the video images captured by the lens assembly and, together with the WiFi module 02, uploads the video images to external devices.

[0068] The power supply component provides power to the wireless camera. It is the energy source for the wireless camera, responsible for providing stable power to the entire system. It ensures the proper functioning of the lens assembly, controller 01, and other electronic components.

[0069] The above embodiments are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model.
