FortiAP Series
Wireless Indoor High Density AP
Fortinet provides the industry’s leading Wi-Fi solutions addressing today’s most pressing ultrahigh density (UHD) challenges, such as high user engagement high network capacity, fast throughput, and low total cost of ownership (TCO). Our solutions leverage the Fortinet Wi-Fi platform, designed and built specifically for UHD venues such as stadiums, arenas, convention centers, shopping malls, transport hubs, auditoriums, campuses, and smart cities.
A complementary component of the Fortinet platform is the FortiAP-HD-431G, an indoorrated, medium-capacity access point (AP), primarily employed for enterprise-grade low- to medium-density environments such as small offices, retail outlets, office branches, hospitality, classrooms and non- public service areas.
The FortiAP-HD-431G leverages the combined power of three 802.11ax radios operating in 4×4:4 MU-MIMO mode over all available Wi-Fi frequency bands 2.4 GHz, 5 GHz, and 6 GHz. The FortiAP-HD-431G enables concurrent triple-radio operation without impacting the radio performance for an aggregate PHY throughput of 8.407 Gbps.
The FortiAP-HD-431G also provides additional capabilities such as advanced radio resource management, active multi-radio client load balancing, and assisted roaming, which are fully supported and managed by the Fortinet WLAN controller. Through a simple and clear user interface, the FortiAP-HD-431G can be easily and quickly configured, managed, and monitored, through the Fortinet WLAN controller with minimal user interaction, providing operational efficiency and system scalability (up to 1000 APs) without compromise.
The FortiAP-HD-431G features integrated, easy-to-configure security technologies providing secure connectivity for employees and guests. Employing the latest 802.11i advanced security features and encryption, with WPA3 authentication, the FortiAP-HD-431G delivers the level of security required in an enterprise or crowded event environment.
Our patent-pending load balancing algorithms performs traffic management to optimize client associations, throughput, and roaming. Based on 802.11k and 802.11v protocols, the algorithm dynamically balances users between intra- and inter-AP radios to maximize radio, client, and network performance and capacity.
