1 and AC+AP .AC are the abbreviations of accesscontrol and access controller, and AP is the abbreviation of accesspoint. Wireless access points are more common in enterprises. Its advantage is that it can control many devices, but its cost is high and it is not suitable for home use. If it has not been renovated, especially villas and duplex buildings, you can really consider this scheme, wiring each room directly and collecting it into the weak box.

2. Wireless routing relay mode. This is the kind of wireless extender we often talk about. Of course, there are WDS wireless bridges in wireless routers, which are all similar. Its advantages are no wiring and low cost. However, there should not be too many routing devices and there should not be more than three levels. As for roaming, although the SSID and password can be changed to the same, roaming is still not so sensitive, and the signal is generally weak before handover.

3. Power cat. This kind of wire is used as the signal carrier without wiring, but it is expensive and needs to be used in pairs. The signal is unstable and may cause interference. It is worth mentioning that the signal of the power cat is loaded on the power current, and the fluctuation of the current itself will definitely affect the signal extraction, so the power cat should be plugged into the wall socket, not the patch panel.
