Set up Force 4600c and NetPoint (PTP, PMP)

When using the Cambium Force 4600c with NetPoint antennas, you can implement various Point-to-Point (PTP) link configurations, optimizing performance for different distances and conditions. Here are the most common configuration types:

1. Short-Range PTP Link

  • Use: Short distances (0-20 km) in urban areas or high-interference zones.
  • Recommended Configuration:
    • Radio: Cambium Force 4600c (WiFi 6E, 4.9 - 6.4 GHz).
      • Antenna: NetPoint NP6-DP-2FT (30 dBi) or NPX6-HP-2FT (30 dBi).
    • Channel: 160 MHz to maximize throughput (up to 4 Gbps aggregate).
    • Polarization: Dual (H/V or Slant ±45° to avoid interference).

:white_check_mark: Advantages: High speed, low latency, ideal for connecting nearby buildings.

2. Mid-Range PTP Link

  • Use: Medium range (0-40 km), ideal for suburban areas.
  • Recommended Configuration:
    • Radio: Cambium Force 4600c.
    • Antenna: NetPoint NP6-DP-3FT (32 dBi) or NetPoint NPX6-HP-3FT (33 dBi).
    • Channel: 80 MHz for a balance between throughput and stability.
    • Fine Alignment: It is essential to optimize alignment due to the larger directional beam.

:white_check_mark: Advantages: Greater range without sacrificing too much bandwidth (~2-3 Gbps).

3. Long-Range PTP Link

  • Use: Critical links of 0-90 km, such as rural areas or city-to-city backbones.
  • Recommended Configuration:
    • Radio: Cambium Force 4600c.
    • Antenna: NetPoint NP6-SDP-4FT (37 dBi) or NetPoint NPX5-SHP-6FT (39 dBi).
    • Channel: 40 MHz to maximize stability and reception sensitivity.
    • Precise Alignment: Use a real-time signal meter (Cambium AlignTool).

:white_check_mark: Advantages: Robust connections over long distances with high gain.


4. Redundant PTP Link (Failover/Backup)

  • Use: Ensure service continuity with a secondary link.
  • Recommended Configuration:
    • Primary Radio: Cambium Force 4600c (on the main frequency).
    • Secondary Radio: Another Force 4600c on a different frequency (6 GHz if the primary is 5 GHz).
    • Antennas: NetPoint NP6-DP-3FT for both links, with a physical separation of at least 1.5 m.

:white_check_mark: Advantages: High availability, continuity in case of primary link failure.
