High-performance fixed, wireless, and mobile communication networks are increasingly vital for global corporations, SMEs, public organizations, and universities. However, designing these networks efficiently remains challenging, with current tools offering limited, unintegrated support. The author addresses this by proposing a more integrated design methodology with robust tool support, emphasizing practical relevance alongside conceptual and theoretical challenges. Key contributions include: 1. **Integrated Design Language Support**: The introduction of a modern network design markup language (NDML), an XML-based notation that uniformly represents all major network elements, their technical properties, interconnections, and configuration issues. Unlike vendor-specific notations, NDML is based on open standards, promoting interoperability and portability, illustrated through several examples. 2. **Design Methodology**: The work presents a complete design workflow that links proven methods, extends them with various options, and focuses on integrating wired and wireless network design, particularly addressing modern standards like IEEE 802.11 and 802.16 with enhanced algorithms. 3. **Tool Support**: A comprehensive set of design tools, including editors, consistency checks, transformation tools, and specific wireless network design tools, supports the methodology. NDML serves as a common notation, ensuring practical applicabil
