What do WIFI module AP and STA modes mean respectively?

In the WIFI module, AP and STA modes respectively represent:

1, AP: wireless access point, which is the creator of wireless network and the central node of the network. The wireless router used by ordinary families or offices is AP.

2.STA site means that every terminal connected to the wireless network (such as laptop, PDA and other networked user equipment) can be called a site.

Extended data:

In wireless network, AP is equivalent to the hub of wired network and can connect all wireless clients. The network card used by the wireless client is a wireless network card, and the transmission medium is air (electromagnetic wave).

Logically speaking, AP is the central point of a wireless unit, through which all wireless signals in the unit can be exchanged. AP is an essential device in the basic mode of WLAN. Although in the absence of AP, a point-to-point wireless local area network can be formed only by using wireless network cards, this kind of wireless local area network is somewhat special and only suitable for temporary wireless connection.

After using AP, you can not only get permanent wireless connection service, but also manage users centrally, which greatly improves the security of wireless network. Generally speaking, wireless AP is a bridge between wireless network and wired network.

Because the coverage of wireless AP is a circular area that spreads outward, it should be placed in the center of the wireless network as far as possible, and the linear distance between each wireless client and wireless AP should not exceed 30m, so as to avoid communication failure due to excessive attenuation of communication signals.

Wireless LAN is mainly composed of base station (STA), access point (AP), wireless medium (WM) and distributed system (DS).

STA is generally a client in WLAN, which can be a computer with a wireless network card or a smart phone with a WiFi module. STA is the most basic unit of WLAN, which can be mobile or fixed.
