What does WIFI relay mean?

WIFI relay is to retransmit the received WIFI signal and expand the coverage of wireless network. Wireless relay mode, that is, wireless AP plays the role of relay in network connection, which can realize signal relay and amplification.

Relay is to combine more than two wireless routers to realize signal relay and amplification, thus making the transmission coverage of WIFI network wider. Relay wireless routers are separated by a certain distance, so that each wireless router has a variety of signal coverage, thus playing the role of expanding WIFI signals.

Wireless relay mode:

1. The wireless distribution system establishes a link between two AP devices through the radio interface. This link can relay traffic from an AP without Ethernet connection to another AP with Ethernet connection. WDS allows up to four point-to-point links to be configured between access points. Generally speaking, in the long-distance wireless relay mode, the central AP supports four APS at most.

2. Although wireless relay mode makes wireless coverage easier and more flexible, it needs the support of high-end AP. If there is a problem in the central AP, the whole WLAN will be paralyzed and redundancy cannot be guaranteed, so the most common mode in application is "wireless roaming mode".

3. This "trunking mode" can only be used in special circumstances where network wiring is impossible, and it can be applied to places where the field is open and it is not convenient to lay Ethernet cables, such as large open office areas, warehouses, docks, etc. There is also a relay AP in the middle, because the two networks are too far away to transmit network signals. This AP only plays the role of relay.
