Scaling Access Networks Without Redesign, Rising OPEX, or Operational Chaos
WISP networks are under more pressure than ever. Spectrum is crowded, ARPU isn’t rising, and competition, from LEO, fixed 5G, and fiber, keeps accelerating. At the same time, networks must scale faster, last longer, and cost less to operate.
For many WISPs, the real challenge isn’t the radio—it’s everything around it.
That’s where cnMatrix™ switching turns architecture into day-to-day operational relief.
The Hidden Complexity at the Tower
As WISP networks grow, tower sites must evolve quickly:
- More radios, more sectors, more services
- Wi-Fi, cameras, backhaul, fiber handoffs
- Mixed generations of equipment
- Lean teams managing hundreds (or thousands) of sites
Manual switch configuration doesn’t scale in this environment. VLAN spreadsheets, color-coded cables, and one-off port configs introduce errors, slow deployments, and increase truck rolls, exactly when margins are tight.
ONE Network: Designed for WISP Reality
Built on Cambium’s ONE Network architecture, cnMatrix allows WISPs to operate the access layer as a system, not a collection of one-off configurations.
With cnMatrix switches managed through cnMaestro™, WISPs get:
- One platform to deploy and manage the entire network
- Consistent configuration from core to tower to subscriber
- Enterprise-grade capability without enterprise pricing
The result is a network that scales without redesign.
Zero-Touch Switching at the Tower
cnMatrix eliminates manual switch configuration using Auto Configuration and Policy-Based Automation (PBA).
No CLI sessions. No port-by-port setup. No tribal knowledge required.
This means:
- Faster tower turn-ups
- Cleaner adds, moves, and changes
- Fewer configuration errors as the network grows
What disappears are spreadsheets, site-specific port notes, and configuration drift between towers.
Purpose-Built for Real-World Tower Conditions
Tower switching isn’t a controlled data center environment. Equipment is exposed to heat, cold, dust, and tight enclosures, often with limited physical access. cnMatrix switches are designed with those realities in mind.
Key tower-optimized features include:
- Extended operating temperature range to support outdoor cabinets and challenging climates without additional cooling infrastructure
- Cambium Sync support to maintain precise timing across radios, access points, and backhaul, which is critical for fixed wireless performance and interference management
- Front-facing interfaces that simplify cable management and maintenance in space-constrained tower enclosures
These design choices reduce installation friction, speed troubleshooting, and make ongoing maintenance easier for field teams, especially across large, geographically distributed networks.
Security That Doesn’t Slow You Down
Security matters, even at the access layer, but it can’t add operational overhead.
cnMatrix improves security automatically by:
- Profiling devices as they connect
- Auto-segmenting traffic by device type
- Enforcing consistent policies across all sites
When devices disconnect, policies are cleaned up automatically, reducing risk and simplifying operations without extra effort from your team.
Predictable Costs That Protect ARPU
Every recurring cost eats into ARPU. cnMatrix helps WISPs keep economics under control with:
- Competitive hardware pricing
- No hidden licensing fees
- Lower OPEX through automation and simplified management
- Long product lifecycles and backward compatibility
It’s switching designed to age well, even as your network continues to evolve.
ONE Platform. One Operational Experience.
When cnMatrix is deployed as part of the Cambium ONE Network, switching stops being a bottleneck and starts becoming an enabler.
From tower to subscriber, everything is managed through cnMaestro, so your team can focus on growing the business, not managing individual ports.
