Hospitality networks are some of the most demanding environments to design. Guests expect the same seamless, fast, and secure connectivity they have at home, if not better. At the same time, the business relies on Wi-Fi for everything from in-room entertainment to IoT, POS, and back-office systems. Achieving this balance requires more than just throwing access points into hallways.

It calls for a structured, end-to-end network design.

Laying the Foundation: Wired Network Infrastructure

A reliable wireless network is only as strong as the wired backbone supporting it. Switches should provide multigigabit throughput with sufficient PoE budgets to power modern access points, which can demand up to 51 watts each with Wi-Fi 6E or Wi-Fi 7 radios. Cabling should be Cat6a or higher to handle both bandwidth and power requirements.

VLANs should be carefully designed to segment traffic into guest, staff, IoT, VoIP, and management networks. In larger deployments, VXLAN can provide scalable segmentation across multiple sites or large properties.

In-Room Access Points: Consistency and Experience

Hallway APs used to be the norm in hotels, but they often led to coverage gaps and inconsistent performance. In-room APs are now preferred because they ensure consistent coverage, improve capacity per room, and reduce attenuation caused by walls.

A best practice is mapping each AP to its own VLAN or VXLAN instance, allowing the hotel to isolate traffic per room or per guest. This approach protects privacy and keeps each room’s network traffic secure.

Wireless Spectrum Planning

Spectrum planning is critical in hospitality to minimize interference and maximize performance.

• 2.4 GHz: Limited to three usable non-overlapping channels. Best left for IoT and legacy devices.

• 5 GHz: The workhorse for most guest traffic, though DFS radar events must be considered.

• 6 GHz: Brings significant new capacity with dozens of clean, non-overlapping channels where supported, making it ideal for high-demand guest services and conferencing.

In practice, 20 MHz channels in 2.4 GHz and 20–40 MHz widths in 5 and 6 GHz are often the right balance for hospitality, focusing on capacity and client density rather than maximum theoretical speeds.

Security and Guest Protection

Strong security is non-negotiable. WPA3 should be the baseline for all new deployments, especially as it is mandatory in the 6 GHz band. Client isolation should be enforced to prevent guest-to-guest traffic, and firewalls or ACLs should segment guest, IoT, and corporate systems.

Captive portals are still widely used, but they add friction. Where possible, more seamless onboarding methods, such as certificate-based authentication or Passpoint, create a smoother guest experience while maintaining security.

Roaming and Performance

In hotels, guests move between lobbies, meeting spaces, restaurants, and leisure areas. Fast, seamless roaming is essential. Enabling features such as 802.11k, r, and v can improve handoff performance, but careful testing with legacy devices is needed to ensure compatibility.

Wi-Fi 7 capabilities such as Multi-Link Operation (MLO) and OFDMA provide improved roaming performance and throughput in dense environments, making them especially valuable in hospitality where device counts are high.

Validation and Ongoing Monitoring

Design doesn’t end once the APs are installed. Validation surveys must confirm that the network performs as expected, measuring primary and secondary signal strength, SNR, channel utilization, and data rates across the site.

Ongoing monitoring and troubleshooting are just as important. A well-managed hospitality WLAN should be continuously assessed for congestion, interference, and client experience issues. This ensures guests always have a reliable, high-performing connection.

Final Thoughts

A successful hospitality network is built from the ground up. From solid wired infrastructure and VLAN/VXLAN design, to in-room AP deployments, to thoughtful spectrum planning across 2.4, 5, and 6 GHz, every layer plays a part. Security and roaming need to be designed in from the start, and validation ensures the guest experience matches the plan on paper.

Done right, the result is a network that supports guests, staff, and critical business systems reliably, setting the stage for a hospitality experience that feels seamless, secure, and future-ready.
