In-building DAS · multi-tenant · AHJ-ready

DAS and small-cell monitoring — every antenna, every BDA, every donor signal on one console.

The fire marshal walks in for the annual NFPA 1221 grid test and the BDA in the basement has been drifting for three weeks — visible in the vendor RMS that nobody opened. From CBRS small-cell to public-safety BDA, from headend room to mezzanine ceiling — telemetry, AHJ test evidence and tenant coordination fused into one operator console.

The reality at portfolio scale

Most AHJ failures are visible the day before.

57%
first-time AHJ test failures
Industry indicative across mid-rise commercial buildings — failed grid tests on initial submission to the fire marshal.
12+
vendor RMS tools per portfolio
Each BDA, DAS headend and small-cell vendor brings its own management plane. Operators log in to all of them.
$30k
fail-and-revisit cost per building
Recoring grid tests, re-permitting and re-mobilising techs once the AHJ has issued conditional approval.

Indicative benchmarks from DAS integrator interviews — your portfolio's numbers will differ. Methodology on request.

What ships in the first 90 days

One operator console, every BDA vendor in the rack.

Drop in next to your existing vendor RMS tools — read-only at first, write-scope per BDA when you trust the runbooks.

Headend + remote unit telemetry, vendor-neutral.

BDA gain, donor signal level, downlink/uplink path balance, fiber link health — normalised across vendor stacks.

  • CommScope, Corning, JMA, SOLiD, Westell + small-cell radios
  • Cable + fiber link diagnostics + PIM signature library
  • RF baseline drift alarms — captured before the AHJ visit
  • Edge gateway at the headend rack — no cloud trip required

AHJ test evidence assembled from the live system.

RSSI grid captures, IFC §510 mapping and sealed PDFs — drafted continuously, not the night before inspection.

  • Auto-mapped to building drawings + IFC §510 layout
  • Sealed evidence packets dated and signed per submission
  • Auditor-mode read-only links for the AHJ inspector

Multi-tenant headend coordination, without the spreadsheet.

Carrier provisioning, change windows, RF performance per tenant — one source of truth for who owes whom what.

  • Per-tenant RF KPIs · share without exposing the fleet
  • Change-window calendar + tenant approval flow
  • Carrier dispute packets · sealed event stream attached

Public-safety NFPA 1221 — same console, different report.

Battery 1-hour-rule monitoring, donor signal alarms, annual test evidence — sharing infrastructure with the carrier DAS.

  • Battery profile + runtime projection · alerts before AHJ visit
  • Donor signal continuous monitoring with threshold alarms
  • Annual NFPA 1221 evidence packs · sealed for the fire marshal
An incident, end to end

From a 4 dB uplink dip in Boston to a sealed AHJ packet — without re-mobilising.

01
BOS-DAS-12 · uplink path − 4 dB · headend room

BDA reports.

ObservOne ingests SNMP and vendor REST telemetry from the BDA, master and remote units — at the headend or via cloud connector. No new on-site hardware.

02
correlation engine

Console correlates.

Donor antenna sweep shows PIM signature at 700 MHz Band 14. Cable contamination probable. Schedule a tech visit during the next tenant change window — no immediate AHJ exposure.

03
NFPA 1221 · evidence sealed

Evidence is auto-logged.

Grid test RSSI map drafted to NFPA 1221 grid specification, sealed and timestamped. Annual recertification packet now 92% complete.

Audit-ready by construction

Annual recertification is a side-effect, not a sprint.
