Fortinet FortiAP 831F
8x8 Wi-Fi 6 (802.11ax), Indoor wireless AP: Tri-radio, Internal antenna, 1 x 5 GE & 1 x GE RJ45 ports

Overview:

This high throughput enterprise class 802.11ax indoor AP provides three radios and 8 spatial streams. This top-of-the line access point supports OFDMA, a 2.5 Gigabit Ethernet port, plus an additional 1 Gbps Ethernet port for PoE diversity. The AP can provide 24/7 scanning across both bands while still providing access on both the 2.4 and 5 GHz bands. The integrated BLE radio can be used for beacons and locationing applications.

Key Features:

• 802.11ax
• Tri-Radio 2.4 GHz + 5 GHz + scanning
• 9 Internal/External Antennas
• 8x8 MU-MIMO
• Up to 1,147 Mbps + 4,804 Mbps

Use Cases:

FortiAPs allow for a versatile collection of installation topologies with options to fit any enterprise.

Campus

A single building with multiple floors, or a corporate or education campus with a group of large buildings.

• High-capacity designs including Dual 5GHz and tri-band with Wi-Fi 6E allow a maximal number of client devices to attach to the network at the same time without over-air congestion
• Complete NOC functionality with network visibility and AIOps simplify a complex network deployment into a solution manageable by IT teams of any size

---

Branch Office / SD-Branch

A highly distributed number of small sites, often with no on-site IT.

• Built in NAC functions* allow secure onboarding of devices at remote locations where IT doesn’t have reliable visibility
• Management orchestration with zero-touch deployment allows for quick and easy rollouts without the need for skilled installers at each site

---

Micro Branch

Ultra small sites that still fall under IT’s responsibility

• Can act as a SASE endpoint as a foundation for zero-trust network access (ZTNA)
• Simple management and provisioning through FortiSASE interface

---

Remote Workers

A remote AP installed at a worker’s home or at micro-branch office space.

• Split tunneling allows local traffic to remain local while sending other traffic to the data center for inspection when needed
• Desktop mounting options for wall-plate models allow the use of Ethernet as well as Wi-Fi connectivity while leveraging the same secure tunnel

---

SMB

Single site or small collection of sites with limited IT resources.

• Built-in NAC functions* bring security to the wireless network with no need to install and manage additional products
• Network and security convergence decreases management overhead while keeping the network secure

*FortiGate-managed installations only.
