The is a highly integrated, single‑chip wireless LAN (WLAN) controller that has powered millions of inexpensive USB Wi‑Fi dongles over the past decade. It is IEEE 802.11b/g/n compliant and operates only in the 2.4 GHz band. The chip integrates a Media Access Controller (MAC), a 1T1R baseband processor, and an RF transceiver all on a single CMOS die, which keeps both the physical size and bill‑of‑materials low. Because of this integration, the RTL8188CU remains a popular choice for manufacturers of ultra‑compact “nano” dongles, as well as for embedded devices, industrial gateways, and Linux‑based soft routers.
Because the RTL8188CU is so widely available and cheap, it appears in many scenarios:
