Realtek 
(https://www.realtek.com/en/products/communications-network-ics/item/rtl8188eus) 
states the following:

"The Realtek RTL8188EUS is an 802.11bgn 2.4G single-chip that integrates 
Wireless LAN (WLAN) and a network USB interface (USB 1.0/1.1/2.0 compatible) 
controller. It combines a WLAN MAC, a 1T1R capable WLAN baseband, and WLAN RF in 
a single chip. The RTL8188EUS provides a complete solution for high-throughput 
performance and low power consumption integrated wireless LAN devices."

The reason there are 5G snippets in the driver is because Realtek uses the base 
code to generate drivers for other chip families such as RTL8192DU that have 
radios for both 2.4 and 5G bands. The RTL81288EU and variants have only a single 
radio.
