Advantages
- Multi‑Gigabit Uplink: 2.5 GbE uplink eliminates bottlenecks, outperforming most competitors’ 1 GbE links.
- Integrated Cisco Ecosystem: Deep integration with DNA Center, WLC, and Embedded Wireless Controller for unified policy, analytics, and automation.
- High‑Density RF Optimization: Features CleanAir®, Rx‑SOP, and Cisco RF Profiles for reliable performance in congested environments.
Disadvantages
- Higher Cost: Premium positioning may be a barrier for budget‑sensitive deployments compared to Aruba or Ubiquiti.
- Stream Count vs. Ruckus: 4×4 vs. R650’s multi‑antenna innovations (SmartMesh™, BeamFlex) which boost real‑world throughput.
- Power Requirements: Requires PoE+ or UPOE, whereas some rivals operate on PoE 802.3af.
