The FAP-422E is our high-density 802.11ac Wave 2 outdoor access point. This enterprise class access point is ideal for large high-density outdoor environments such as an outside office building or recreation area. It supports MU-MiMO giving excellent performance throughput and the ability to support 3 simultaneous devices.

The FortiAP-S series are cloud-managed access points designed for deployment in SMBs and distributed enterprise remote sites. Managed through the free FortiCloud provisioning and management portal, they eliminate the CAPEX and complexity of deploying WLAN controllers and management servers. Two models come with 3x3 internal antennas, and two are equipped with connectors for use with external directional or panel antennas.

Cloud WiFi with Comprehensive Threat Protection

Unlike any other access points on the market, they are equipped with extra memory and a powerful dual-core processor, which enable them to perform real-time security processing on the AP itself, providing complete protection against all manner of WiFi and cyber-threats at the network edge. With Fortinet’s award winning security technology embedded in the AP, the FortiAP-S series provides the most compact solution for complete content and application security in a Cloud WiFi architecture. This has significant implications for ease-of-deployment, operational efficiency and total cost of ownership.
