Problems solved by technology
[0004] In the above-mentioned multi-beam smart antenna control system, the wireless network card chip needs to configure the antenna beam for each data message to be sent according to the same algorithm as in the CPU, which puts forward high requirements on the compatibility of the wireless network card chip. If you want to take into account the processing speed at the same time, the cost of the wireless network card chip will be greatly increased

Embodiment Construction
[0022] figure 2 A schematic structural diagram of a control system for a smart antenna provided in Embodiment 1 of the present invention, as shown in figure 2 As shown, the control system of the smart antenna may include: a CPU, a wireless network card chip and an antenna control chip. Wherein, the CPU is used for: synchronizing the data message queue to be sent to the wireless network card chip and the antenna control chip, and sending the antenna beam configuration corresponding to each data message in the data message queue to be sent to the antenna control chip. The wireless network card chip is used for: sending each data packet to the smart antenna according to the order of the data packets in the received data packet queue. The antenna control chip is used to: if it is detected that the wireless network card chip starts to send data packets to the smart antenna, then obtain the antenna beam configuration corresponding to each data packet according to the order of the...

The invention provides an intelligent antenna control system and a packet transmission method. The system comprises a central processor, a wireless network card chip and an antenna control chip; wherein the central processor is used for synchronously transmitting a data packet queue to be transmitted to the wireless network card chip and the antenna control chip, and transmitting antenna beam configuration corresponding to each data packet in the data packet queue to be transmitted to the antenna control chip; the wireless network card chip is used for transmitting each data packet to an intelligent antenna according to the sequence of data packets in the data packet queue; and the antenna control chip is used for obtaining the antenna beam configuration corresponding to each data packet according to the sequence of the data packets in the data packet queue when the wireless network card chip is detected to start transmitting data packets to the intelligent antenna, and controlling transmission of each data packet by the intelligent antenna according to the corresponding antenna beam configuration.
Description
technical field [0001] The invention relates to communication technology, in particular to a smart antenna control system and a message sending method. Background technique [0002] At present, smart antenna technology is getting more and more attention. The ITU has made it clear that the smart antenna technology will be the main direction for the development of mobile communication technology after three generations. The wireless local area network (Wireless Local Area Network, referred to as: WLAN) system introduces smart antenna technology, which can expand its propagation range, improve the reliability of signal transmission, and enable the system to transmit data at a high rate, with anti-fading, anti-interference, and increased system Capacity and the realization of mobile station positioning and other characteristics. [0003] Multi-beam smart antenna is one of the two main types of smart antenna. It uses multiple parallel beams to cover the entire user area. The di...
