The invention provides a system for reducing roaming time delay of wireless client terminal equipment, which relates to the technical field of network communication, and comprises a plurality of wireless access points, wherein each wireless access point adopts the same wireless network name, and each wireless access point is connected with a gateway through a switch; at least one wireless client terminal equipment, wherein each wireless client terminal equipment carries two communication modules, the two communication modules and the gateway correspondingly form a dual communication link through the wireless access points and the switch respectively, in the roaming process of the wireless client terminal equipment, message receiving and sending between the wireless client terminal equipment and the gateway are realized through the dual communication link. The system has the beneficial effects that zero packet loss of the wireless client terminal equipment in the roaming process is realized through a dual-communication link technology; a common AP can be used as the wireless access point AP, and extra air interface overhead does not need to be increased; and the networking complexity is reduced.
Description
technical field [0001] The invention relates to the technical field of network communication, in particular to a system for reducing roaming delay of wireless client terminal equipment. Background technique [0002] WIFI CPE (WIFI Customer Premise Equipment, wireless client terminal equipment) is a wireless terminal access device that receives wifi signals. It can replace wireless client devices such as wireless network cards, and can receive wireless routers, wireless APs (Wireless Access Point, wireless access Access point), wireless base station and other wireless signals, is a new type of wireless terminal access equipment. Taking the AGV car as an example, the AGV car is used as a wireless client terminal device. During the rapid movement, it involves the roaming of the wireless client terminal device between wireless APs. How to reduce the roaming delay of the wireless client terminal device and reduce the number of wireless client terminal devices? Packet loss during...
