Every network we design has a case file. Here is what’s inside one.

Five stages. One recurring cycle. The physics of the space, measured — not assumed.

“Coverage is a claim until someone walks the space with the meter running. We don’t sell the claim. We run the cycle.”

DESIGN → MEASURE → VALIDATE → CORRECT → MONITOR — and back to DESIGN when the building changes, because it always does.

MRI Suite — Faraday-shielded enclosure

VOID — ORIGINAL AP-11 POSITION AP-11 — original spec position voided. Fell inside the MRI suite’s Faraday-shielded enclosure. Relocated to current position before install. Wall, Grid C4 — reinforced concrete, 14 dB predicted loss Ceiling mount, 10.5 ft AFF — standard drop tile zone AP-04 AP-09 AP-11 Exhibit A / Stage 01 — Design
Illustrative — Case 24-0387 (composite, not client data)

Before a single access point ships, the space is already modeled.

We build a predictive RF model from the architectural drawings — construction materials, ceiling heights, mechanical rooms, shielded suites — before a device count is finalized or a purchase order is cut. In this file, the model caught a conflict early: the specified AP-11 position fell inside the imaging suite’s Faraday-shielded enclosure. It moved on paper, at no cost, three weeks before drywall. The model decides what gets specified, not a preferred vendor — the same independence that governs our technology partner ecosystem.

Predictive coverage model, ambulatory care wing — 340,000 sq ft, reinforced concrete construction, three lead-lined imaging suites. Modeled before any hardware was ordered.

Exhibit B / Stage 02 — Measure — Illustrative composite

Zone	Avg RSSI	Avg SNR	Ch. Util.	Samples
Zone 1	−54 dBm	28 dB	22%	38
Zone 2	−58 dBm	24 dB	31%	36
Zone 3	−69 dBm	14 dB	44%	34
Zone 4	−61 dBm	21 dB	52%	37
Zone 5	−71 dBm	12 dB	39%	35
Zone 6	−57 dBm	26 dB	19%	34

Then someone walks the space with the meter running.

A predictive model is a hypothesis. We validate it in the field with a full RF site survey — signal strength, noise floor, channel utilization, measured device-in-hand, zone by zone, after install. Two of six zones in this file came back below threshold on the first pass. That’s not a failure of the design. It’s the measurement doing its job.

Post-install validation walk, Zones 1–6, 214 measurement points, 2.4 / 5 / 6 GHz.

Exhibit C / Stage 03 — Validate — Illustrative composite

Coverage without proof of capacity is a rendering, not a network.

Capacity validation under simulated peak load, three device classes, six zones. Zone 4 exceeded its roaming handoff target under simulated peak load.

Exhibit D / Stage 04 — Reconcile — Illustrative composite

When the measurement disagrees with the model, the model loses.

1 — AP-09, relocated 11 ft NE — after Zone 4 handoff failure. See Exhibit C.

2 — AP-04, raised 9→10.5 ft AFF — ceiling-tile conflict found during install.

3 — AP-11, omni swapped for directional patch — Grid C4 wall loss exceeded model by 4 dB. See Exhibit A.

Field corrections, redlined against the original design — three revisions, one measured cause each.

Exhibit E / Stage 05 — Monitor — Illustrative composite

Networks drift. The measurement doesn’t end at handoff.

CAPACITY HEADROOM — IMAGING WING6% — BREACHED

Firmware updates. Tenants move walls. Device counts grow past what the original design assumed. Where a client configures ongoing monitoring, TekFidelityIQ can track uptime, roaming success, interference, and capacity headroom, and flag drift before a user notices it — that visibility requires separate setup and is not automatic after handover. On day 268, capacity headroom crossed threshold in the imaging wing — the same wall, the same antenna, first flagged in Exhibit A. The file reopened. Not a new project — the same cycle, back at DESIGN.

The practice, plainly.

Network and infrastructure engineering — planning, architecture, implementation, troubleshooting and ongoing support. TekFidelity works on LAN and WAN planning, network setup and configuration, infrastructure assessments, site technology planning, IT equipment selection and deployment planning, ISP and connectivity coordination, installation oversight, cutover and migration support, infrastructure validation, and multi-site technology rollouts. Wireless is the deepest specialization inside this practice, not the boundary of it.

“We are opening or expanding a location and need the technology environment planned.”

Engagements can cover what the site actually needs before anything is ordered — connectivity, equipment, cabling and rack or closet readiness, coordinated against the building programme rather than retrofitted after handover.

“Our network is unreliable and nobody can tell us why.”

Network and connectivity troubleshooting starts from measurement: where the failure actually occurs, whether it is capacity, configuration, physical infrastructure, the provider circuit or the wireless environment. When the evidence points specifically at Wi-Fi, that work continues as wireless surveys, validation and RF troubleshooting.

“Our equipment is aging and replacing it cannot disrupt operations.”

Lifecycle refresh work covers assessing what is in place, identifying what is unsupported or near end of life, setting replacement priorities and standards, and sequencing deployment and cutover so the environment keeps running through the change. The strategy side of that decision sits with technology strategy and modernization; the delivery side can run through program and project leadership.

“We need someone technical to coordinate everyone involved.”

TekFidelity can act as the technical bridge between leadership, end users, internal IT, facilities, vendors, installers and service providers — translating between them and holding the sequence together so the work is not coordinated by whoever happens to be on site.

“We need the environment assessed before we invest.”

Infrastructure assessment establishes what exists, what is actually failing, what is worth keeping and what an upgrade would genuinely require — before a budget is committed to a product.

“We need help after it is deployed.”

Managed technology support can continue after implementation: ongoing network and wireless support, troubleshooting, vendor coordination, recurring health checks and lifecycle tracking. Where continuous wireless visibility is useful, TekFidelity also operates TekFidelityIQ for enterprise Wi-Fi environments.

Within wireless specifically, the two deepest engagements are predictive enterprise Wi-Fi and RF design before deployment, and site surveys, post-install validation and troubleshooting for environments that already exist. This is where TekFidelity started, and it remains the practice with the deepest evidence behind every recommendation.

Bring us the building. We’ll bring the file.
