Network infrastructure is the foundation that enables all connected systems in a hotel, from guest Wi-Fi, IPTV, and mobile keys to smart room sensors, property management system (PMS) integration, and IoT devices. A high-capacity, well-segmented network ensures reliable performance for both guests and operational systems. Poor network design can limit the ability to deploy newer technologies, cause performance issues, and lead to guest complaints even if individual devices are high quality (because they cannot communicate reliably). Investing early in structured cabling, sufficient wireless access points, bandwidth planning, and security segregation future-proofs your hotel.
