Q:WIFI wireless relay coverage
Wireless repeater is an effective solution to the problem of signal damage and attenuation. For example, a repeater provides a connection that reaches the remote range, which does not have access to the wireless network. Perhaps the router in your home or office does not cover the entire range of wireless users that need to be connected, such as a yard or basement. Placing a repeater between coverage and non coverage ranges provides connectivity within the full space range. Because wireless repeaters add holes to coverage.

Yes, repeaters have this function in routers and switches, HUB, and so on
Q:Should the two wireless routing be chosen as a relay mode or a bridging mode?
