2. Mesh Networking CapabilitiesIPQ4019 Mesh

• Software Support: Compatible with OpenWrt, Qualcomm SON (Self-Organizing Network), and OpenWiFi. Supports B.A.T.M.A.N and 802.11s Mesh protocols.
• Performance:
  • Dual-band 2x2 design, Mesh backhaul mainly relies on 5GHz.
  • Limited throughput (802.11ac 867Mbps), performance drops with multiple hops.
  • Cortex-A7 CPU may bottleneck under large-scale Mesh deployments.
    
    
• Use Cases: Small businesses, home Mesh networks, or industrial IoT with low bandwidth needs.
  
  

IPQ5018 Mesh

• Software Support: Also supports OpenWrt, OpenWiFi, and WiFi 6 Mesh standards (EasyMesh, 802.11s).
• Performance:
  • WiFi 6 features such as OFDMA and BSS Coloring improve concurrency and interference management.
  • Supports 160MHz channels, enabling higher Mesh backhaul capacity.
  • Higher CPU performance and PCIe 3.0 expandability allow external radios (QCN6102/6122) for tri-band Mesh (2.4G + 5G + 6G).
    
    
• Use Cases: Medium-to-large enterprises, campus networks, outdoor coverage, and latency-sensitive industrial applications (e.g., smart factories, mining, surveillance).
