Private 5G for Industrial Sites: A Realistic Look at What It Takes

Private 5G — particularly in CBRS spectrum in the US — is finally moving from pilot to production at industrial sites. But the marketing has gotten ahead of the engineering reality.

The Spectrum Is Real, But Shared

CBRS gives you 150 MHz of usable mid-band spectrum without a carrier contract. Priority Access Licenses (PALs) provide protected channels in many counties; General Authorized Access (GAA) is opportunistic. The Spectrum Access System (SAS) coordinates everything dynamically. For most industrial sites, GAA is sufficient — but you must design with the possibility of channel preemption.

Latency Claims Need Asterisks

"1 ms 5G latency" assumes URLLC features, optimized core, and tight RAN topology. Real deployments using off-the-shelf 5G NSA equipment commonly see 15–30 ms round-trip — better than Wi-Fi, not magical.

You Still Need a Core

Private 5G means private 5G core. Whether on-prem or hosted, the 5GC is non-trivial software with operational requirements. Plan for monitoring, patching, and at least one engineer who understands the difference between AMF, SMF, and UPF.

Where It Genuinely Wins

Outdoor coverage at scale (mines, ports, refineries), high-density device populations, mobility between coverage zones, and deterministic QoS for mission-critical traffic. If your application is "fixed laptops on an office floor," Wi-Fi 6E is almost always the right answer.
