Abstract

The present invention relates to a portable control device suitable for wireless multi-point access in a large space. Several wireless communication devices, a CCA threshold control device, an AP transmission power control device, and an access optimization device are respectively arranged in each containing space to which it belongs. , dual-frequency communication control device, MU‑MIMO communication control device, and a main control device is also installed in the accommodation space, each device is equipped with an independent control port, and each control port is connected to the main control device through a data control bus. A power supply device is provided, and the power supply device is connected to the power supply ports of other devices. A baffle is arranged on the periphery of the equipment support, and a man-machine interaction device is arranged on the baffle. In this way, the possibility of multiple devices sharing the air interface can be reduced, more user access can be satisfied, and data throughput can be improved. Different antenna lobes can be formed to avoid unnecessary interference. The transmit power of the AP can be reasonably adjusted during use to reduce adjacent interference.

Description

technical field [0001] The invention relates to a wireless control device, in particular to a portable control device suitable for wireless multi-point access in a large space. Background technique [0002] In the field of wireless transmission of data information, there are currently two commonly used communication technologies: one is to use wireless transmission source equipment and data codec equipment for data acquisition and encoding, and to perform one or more access forwarding through relay equipment Work, and finally the receiving source device and the data codec device complete the data receiving and decoding, and realize the transmission of the digitally coded data content in the wireless network. The advantage of this method is that the data transmission speed and wireless bandwidth can be adjusted according to the power and distance of various sources; the disadvantage is that the use environment requirements of the transmitting and receiving equipment are relat...
