This design features a black and white illustration of a Wi-Fi signal icon, which is a stylized representation of a radio wave. The icon is typically used to indicate the presence or availability of a wireless network. It is a simple, yet universally recognized symbol for wireless connectivity. The signal icon is placed on a white background, which contrasts with the black color of the icon, making it stand out. There is also a small black arrow pointing towards the signal icon, which could be interpreted as a directional indicator or a symbol for a Wi-Fi signal strength.
