Outdoor Wi‑Fi 7 for Petrochemical Sites A vendor‑agnostic playbook for deployment—and hitting ROI by the next turnaround
Why Wi‑Fi 7, and why now?
Large refineries and chemical plants stretch across tank farms, process units, loading racks, and laydown yards. During day‑to‑day operations—and especially during turnarounds—you need high‑throughput, low‑latency connectivity for thousands of contractors, digital work packs, inspection video, condition monitoring, and mobile tools. Wi‑Fi 7 (802.11be) finally brings outdoor‑ready capabilities that matter on the deck plates:
- Multi‑Link Operation (MLO): Clients can use 5 GHz and 6 GHz together for higher throughput and more consistent latency—useful when RF conditions shift around steel.
- Up to 320 MHz channels + 4096‑QAM (where spectrum and regulations allow): Big headroom for dense contractor camps, AR/remote expert video, and high‑rate cameras.
- 6 GHz with AFC (Automated Frequency Coordination): In regions where standard‑power outdoor 6 GHz is permitted via AFC, you can safely run high‑power outdoor links without stepping on incumbents.
- Better spectral efficiency (e.g., multi‑RU scheduling, puncturing): Keeps sessions moving even when channels are partially occupied by interference.
Bottom line: outdoor Wi‑Fi 7 gives you more usable capacity and reliability. For plants that run major turnarounds every 12–24 months, that can translate into payback by the next cycle.
Vendor‑agnostic architecture options
Clover IQ designs and supports multi‑vendor environments. We’ll help you choose what fits—not force a stack.
Option A — All‑Wi‑Fi 7 outdoor fabric
- Where it shines: Contractor villages, laydown yards, warehouses, parking, canteens, non‑classified areas.
- Pros: Lowest cost/bit; broad device compatibility; easy to scale with temporary mesh for TA.
- Considerations: RF planning around process steel; AFC availability for 6 GHz; hazardous‑area compliance.
Option B — Hybrid: Wi‑Fi 7 + Private LTE/5G
- Where it shines: Plants needing voice/PTT mobility at the edge, AGVs/forklifts, roaming tools in canyons of metal.
- Pros: SIM‑based mobility and QoS for critical flows (PLTE/5G), plus Wi‑Fi 7 for high‑throughput apps and cameras.
- Considerations: Policy‑based steering, shared identity, and segmentation between SIM and cert‑based clients.
Option C — TA overlay (temporary)
- Where it shines: Rapid augmentation during turnarounds.
- Pros: Pre‑staged Wi‑Fi 7 mesh nodes, trailer‑based IDFs, and battery/solar options slash setup time and recurring rentals.
- Considerations: Lightning protection, temporary fiber drops, and contractor onboarding at scale.
Option D — Hazardous‑area builds
- Where it shines: Class I/Division 2 or ATEX/IECEx Zone 2 perimeters and access routes.
- Pros: Rated enclosures, intrinsically safe antennas, and purge/pressurization kits extend coverage safely.
- Considerations: Work‑permits, bonding/earthing, temperature ratings, and corrosion‑resistant (NEMA 4X/IP66/67) hardware.
Deployment blueprint (what “good” looks like)
- Business‑level design (2–3 weeks) Map use cases to SLOs: connected worker apps, digital permits, inspection video (bit‑rate/latency), camera counts, and TA headcount peaks.
- RF and hazard‑class survey
- Physical & power
- Security & segmentation

ROI by the next turnaround: an honest model
Your numbers will vary, but here’s a transparent, vendor‑neutral example you can scale up or down. We show both conservative and TA‑intensive scenarios.
Assumptions (mid‑size site)
Capex (one‑time):
- 120 outdoor Wi‑Fi 7 APs @ $2,800 → $336,000
- 30 hazardous‑area enclosures @ $2,500 → $75,000
- 12 IDFs with 48‑port PoE++ @ $5,500 → $66,000
- UPS & lightning/SPD (12 IDFs @ $2,000) → $24,000
- Fiber/copper/conduit → $180,000
- Controllers/licensing/NMS (perpetual + 3‑yr support) → $120,000
- Design/survey/PM → $110,000
- Installation labor → $180,000
Total Capex: Add step‑by‑step:
- 336,000 + 75,000 = 411,000
- 411,000 + 66,000 = 477,000
- 477,000 + 24,000 = 501,000
- 501,000 + 180,000 = 681,000
- 681,000 + 120,000 = 801,000
- 801,000 + 110,000 = 911,000
- 911,000 + 180,000 = 1,091,000 → $1.091M
Opex (annual):
- Support (≈12% of $621,000 hardware/software) → $74,520
- NMS/subscriptions → $40,000
- Power/site costs → $12,000 Total Opex: 74,520 + 40,000 + 12,000 = $126,520
Benefits within one turnaround cycle
Common savings buckets (adjust to your reality):
- Digital permits & work‑packs time savings (contractors):
- Eliminated temporary network rentals (COWs, pop‑up Wi‑Fi): $180,000 per event
- Avoided cabling/scaffolding for temp cameras: 60 runs × $1,200 = $72,000
- Cellular offload (300 tablets; plan reduction by $20/mo): 300 × 20 × 12 = $72,000
- Remote expert / fewer site fly‑outs: 40 trips × $2,000 = $80,000
Totals
- Conservative benefits: 325,000 + 180,000 + 72,000 + 72,000 + 80,000 = $729,000/year
- TA‑intensive benefits: 975,000 + 180,000 + 72,000 + 72,000 + 80,000 = $1,379,000/year
These are conservative, line‑item, auditable levers—no hand‑waving about “productivity.” In workshops we swap in your actual contractor counts, day rates, TA duration, and historical rentals.
Practical tips for petrochemical sites
- Design for capacity, not just coverage. Turnarounds spike to thousands of clients per zone; plan AP density and airtime for peak days.
- Treat 6 GHz as premium lanes. Use AFC‑enabled outdoor radios where permitted; keep legacy/IoT on 2.4/5 GHz.
- Engineer for weather and corrosion. NEMA 4X/IP66/67 enclosures, stainless mounts, UV‑rated cabling, and proper drainage/breathing.
- Protect the plant first. Follow electrical classification rules; bond every mast; use surge protection and fiber in hazardous runs.
- Onboard at scale. Certificate‑based onboarding for staff; individualized PSKs and sponsor‑approved flows for contractors (thousands/day).
- Instrument the network. Per‑client telemetry, RF analytics, and simple SLOs (e.g., attach time, roaming, MCS floors) you can show Ops daily.
A 90‑day path to results
Days 0–15: Business & RF discovery, hazard‑class walk‑down, spectrum samples, and AFC/regulatory checks. Days 16–45: Low‑risk pilot (e.g., a tank farm or loading rack): 8–12 APs, contractor onboarding, 15–20 cameras, and remote expert workflows. Days 46–75: Expand design, finalize BOM across vendors, security patterns (EAP‑TLS, segmentation), and TA overlay plan. Days 76–90: Implementation in priority zones. Hand‑off runbooks and SLO dashboard—or keep it under Clover IQ managed services through the TA.
