- Zero Trust NAC Enhancements: Automates device posture checks for 802.1X authenticated clients using FortiClient EMS 7.2.1+ integration.
- Wireless Intrusion Prevention: Adds 18 new FortiGuard signatures targeting rogue APs and Evil Twin attacks in Wi-Fi 6E environments.
2. Performance & Reliability
- Dual 5G NR Support: Achieves 2.3 Gbps aggregate throughput on Qualcomm SDX65 modems with carrier aggregation (CA) enabled.
- PoE+ Optimization: Reduces power consumption by 22% through dynamic voltage scaling for connected IoT devices.
- Mesh Network Stability: Implements B.A.T.M.A.N. Advanced v2024.1 protocol for seamless client roaming across 50+ nodes.
3. Protocol & Compliance
- WPA3-Enterprise 192-bit Mode: Supports NIST-compliant CNSA Suite cryptography for government deployments.
- Industrial IoT Protections: Adds Modbus TCP/RTU deep packet inspection for SCADA systems.
Compatibility and Requirements
Supported Hardware Matrix
| Model | Wireless Standards | PoE Budget | Minimum FortiOS |
|---|---|---|---|
| FortiWifi 81F_2R_3G4G_POE | Wi-Fi 6E (802.11ax) | 90W (802.3bt) | 7.2.1 |
System Requirements
- Controller Compatibility: Requires FortiLAN Cloud 7.2.1+ or FortiManager 7.4.2 for centralized policy management.
- Cellular Modems: Validated with Quectel RG520N-EU and Fibocom FM350-GL 5G modules.
Limitations and Restrictions
-
Upgrade Constraints
- Direct upgrades from FortiOS 6.4.x require intermediate migration to 7.0.9 with 8GB+ free storage.
- Mesh networks mixing 7.2.1 and 7.2.0 nodes experience 15% throughput degradation.
-
Feature Dependencies
- SD-WAN application steering requires FortiCare Enterprise License (FC-ENT-3Y1Y).
- 5G carrier aggregation limited to T-Mobile NSA n41/n71 and Verizon C-band n77/n78 combinations.
-
Known Issues
- Intermittent SNMP traps loss during high PoE load (resolved in 7.2.2).
- RADIUS CoA packet drops when using FreeRADIUS 3.2.1 (workaround: enable UDP checksum offloading).
