Problems solved by technology

The IEEE 802.11 wireless local area network standard (WLAN) adopts CSMA / CA (Carrier Sense Multiple Access with Collision Avoidance, multiple access protocol), but the performance of the CSMA / CA protocol is not good in some scenarios, such as real-time transmission requirements VOIP (Voice over Internet Protocol, network voice telephony), video streaming and other services and long-distance communication, etc., the problem is particularly prominent when the channel competition environment is fierce

In addition, because the CSMA / CA protocol for multi-user access mainly relies on the competition of each wireless access device to obtain air interface resources for wireless communication, and there is no unified control node for control, the user QoS delay is high, and the competition When the resource overhead is large, the resource utilization rate of the air interface is low, resulting in a low overall resource utilization rate, and the average transmission rate is much lower than the theoretical rate of the air interface.
