Create a vertical smartphone wallpaper with a black background, featuring subtle elements of telecommunications, such as glowing red fiber optic cables and abstract network lines. Place the white 'Landtech' logo prominently in the center, ensuring it contrasts well against the dark background. The design should feel modern, sleek, and professional, emphasizing a futuristic tech vibe. Leave sufficient empty space around the logo for a clean and minimalist aesthetic
