(802.11IEEE 802.11 is a set of protocol standards that define communication for a Wireless Local Area Network (WLAN). In order for WiFi to work between different devices, they all need to agree on how they are going to communicate. The current version of the standard is IEEE 802.11-2007, with many amendments such as 802.11a, 802.11b, 802.11g, and 802.11n.b/g/n up to 150Mbps with
APA WiFi Access Point (AP) is a device that creates a wireless local area network, or WLAN, and acts as a central hub that allows other devices, such as smartphones or computers, to connect to it over WiFi./STAA WiFi Station (STA) is a device that has the capability to connect to an existing WiFi network as a client in the same way other devices, such as smartphones or computers, join an established network and communicate with other devices on that network or access the internet./AP+STAA WiFi device in AP+STA mode acts as both an Access Point (AP) as well as a Station (STA), where the device can connect to an existing network as a client (STA) while simultaneously hosting its own network (AP) for other devices to connect to.

The ESP32-WROOM-32U module
(Datasheet PDF)
contains an ESP32-D0WDQ6SoCSystem On a Chip with an Xtensa
32-bit LX6 Dual-Core 80MHz to 240MHz processor,
4MB/8MB/16MBSPISerial Peripheral Interface Flash memory chip, and a uFL connector for an
external antenna.
Most 2.4GHz antennas have an SMASubMiniature version A (SMA) connector connector, so an uFL/IPEX to SMA
cable will be needed if the antenna does not come with one. There are two factors to consider when selecting an
antenna for the ESP32: impedance matching and antenna frequency range. The ESP32 uses a 50Ω impedance on the
antenna output, which is also the standard, and the 2.4GHz WiFi and Bluetooth frequency range is common
world-wide.
