• Ultra-fast tri-band performance for dense environments. The FortiAP 443K provides combined data rates up to 21.32 Gbps across three bands (2.4 GHz, 5 GHz, and 6 GHz), enabling seamless support for bandwidth-intensive tasks such as video conferencing, cloud collaboration, large file transfers, and real-time applications. With advanced radio technologies, this access point shines in high-density spaces where dozens or hundreds of devices compete for airtime.
• Wi‑Fi 6/6E and Wi‑Fi 7 readiness in a single indoor device. The 443K embraces the evolution of wireless standards, including IEEE 802.11ax (Wi‑Fi 6) and IEEE 802.11be (Wi‑Fi 7) across three bands. This combination delivers higher throughput, improved efficiency, and lower latency even in crowded networks, while enabling smarter spectrum management through OFDMA, MU‑MIMO, and advanced scheduling features.
• Integrated Fortinet security and security fabric integration. As part of Fortinet’s Security Fabric, the 443K provides enterprise-grade protection at the network edge. Features include WPA3 and 802.1X authentication, RADIUS support, TLS encryption, and centralized threat protection aligned with FortiGuard services. This makes it easier to enforce consistent security policies across wired and wireless segments while simplifying compliance and incident response.
• Centralized management, policy control, and zero-touch deployment. The FortiAP 443K is designed for scalable management via FortiGate, FortiCloud, or Fortinet’s ecosystem. Centralized configuration, firmware updates, and policy enforcement reduce on-site administration overhead. Zero-touch provisioning enables rapid onboarding of new APs across multiple sites, ensuring a uniform security and performance baseline for the entire network.
• Reliable indoor deployment with flexible power options and enterprise resilience. Built for indoor installation, the 443K supports standard Ethernet with PoE+, enabling convenient ceiling or wall mounting without separate power infrastructure. Its robust hardware design, cooling, and reliability features help deliver consistent performance in varying indoor conditions while minimizing maintenance downtime.

how to install Fortinet FortiAP 443K

• Plan placement and coverage. Assess the floor plan to identify central locations that maximize coverage and minimize interference. Use heat maps or predictive analytics to determine optimal AP density. Position the 443K to balance load across the space, prioritizing high-usage zones such as conference rooms, lobbies, and open work areas.
• Power and network wiring. Connect the FortiAP 443K to a PoE+ capable switch using an Ethernet cable. Ensure the switch provides sufficient power and that cabling is compliant with your building’s electrical standards. If PoE+ is not available in a location, use a compatible PoE injector, but PoE+ is recommended for reliability and performance.
• Adopt and configure from FortiGate or FortiCloud. Access your FortiGate management interface or FortiCloud portal and adopt the FortiAP 443K. Assign it to the appropriate device group, site, and policy. Confirm that the AP registers correctly and receives the correct firmware build.
• Set up SSIDs, security, and VLANs. Create one or more SSIDs and configure security settings (prefer WPA3 with strong passphrases or 802.1X authentication). Map SSIDs to VLANs as needed to segment guest traffic from the corporate network and to enforce policy-based access controls.
• Enable performance features and roaming optimizations. Activate features such as band steering, load balancing, OFDMA, and MU‑MIMO to maximize capacity and improve user experience. Configure roaming enhancements (802.11k/v/r) to ensure seamless handoffs as clients move through the space.
• Monitor and fine-tune. After deployment, monitor performance, interference, and client distribution through FortiGate/FortiCloud dashboards. Adjust channel plans, power levels, and client load balancing to sustain optimal performance as network conditions evolve.
