Field data for network design and verification

Wi‑Fi Site Survey

We conduct Wi‑Fi site surveys for a defined purpose: preparing a design, investigating a problem area, or checking a network after changes. Before the visit, we agree on the site, measurement routes, client device workflows, and the conditions needed for representative results.

Wi-Fi Site SurveyThe plan of the site shows the route of field measurements, control points and transition to maps and engineering report.

What is a Wi‑Fi site survey?

A Wi‑Fi site survey collects and analyzes field data on the RF environment and network performance in agreed areas and operating conditions. The customer receives a report covering routes, maps, observations, limitations, and recommendations within the contractual scope. The survey does not itself provide a complete new network design or diagnose every possible cause of a fault. Design defines the target solution; an audit relates observed symptoms to the RF, network, client device, and application layers.

When field measurements are needed

01

Before designing a complex site

Plans do not capture actual materials, interference, site access, or the RF environment. We determine whether a site visit is needed after reviewing the project inputs and risks.

02

When issues are reported in specific zones or along routes

Measurements establish where a problem occurs and under what conditions. If its cause may lie beyond the RF layer, the survey forms part of an audit rather than replacing it.

03

After installation or significant changes

We compare actual performance with the agreed requirements and acceptance program. The checks depend on the design, client devices, and applications.

04

After changing the layout or equipment

New racks, partitions, production lines, access points, or client devices can change network conditions. The scale and risk of the changes determine whether another survey is needed.

How to prepare for a Wi‑Fi site survey

If some information is unavailable, we establish which data our team can collect and which materials the customer must provide before estimating the work.

How a Wi‑Fi site survey works

  1. 01

    Clarify the task and boundaries

    Document the areas, workflows, initial requirements, access restrictions, and expected deliverables.

  2. 02

    Prepare the program and routes

    Define measurement conditions, checkpoints, measurement heights, and the sequence of work on site.

  3. 03

    Collect field data

    We work according to the agreed program and note deviations from the baseline.

  4. 04

    Analyze the results

    Compare measurements, plans, configurations, and observations within the agreed task.

  5. 05

    Provide the report and explanations

    We record conclusions, limitations, recommendations and data that may be needed in the next step.

What the customer receives

  • 01Program and boundaries of the performed survey;
  • 02Plans with routes and checkpoints;
  • 03Heat maps and tables for the parameters actually measured;
  • 04Description of conditions, limitations and detected deviations;
  • 05Recommendations within the scope of the survey;
  • 06Raw exports or project files only where specified in the contract.

What determines timeframes and cost

The estimate depends on the number and size of areas, floors and heights, route accessibility, site operating conditions, methods, client device workflows, location, and report contents. We calculate the schedule and cost after reviewing the plan, survey objectives, areas, and access restrictions.

Questions and answers

Wi‑Fi site survey FAQ

01Can Wi‑Fi be designed from plans alone?

Current plans and requirements can support a preliminary predictive model. Whether this is sufficient depends on the accuracy of drawings, materials, heights, the future layout, client devices, and the consequences of an error. For an operating site, a complex environment, or incomplete inputs, an engineer separately assesses the need for an inspection and field measurements. These should be justified rather than prescribed automatically or replaced by assumptions.

02How does a Wi‑Fi site survey differ from a Wi‑Fi network audit?

A Wi‑Fi site survey records the RF environment, coverage, and agreed client device workflows in specific areas. An audit starts with an observed symptom and investigates possible causes across the RF layer, configuration, wired network, client device, and application. Field measurements may form part of an audit, but they do not by themselves establish the cause of every fault or replace checks at the other layers.

03Can you take measurements at an operating site?

This depends on the operating schedule, safety requirements, and access to measurement routes. Before work starts, we agree on site escorts, movement restrictions, permitted work windows, and the conditions needed for representative data. If the required operating conditions cannot be observed safely or without disrupting operations, we record that limitation in the report and discuss additional checks separately.

04What information do you need before the site visit?

We need the survey objective, a current plan, the areas to be surveyed, access restrictions, and a contact responsible for the site. For an existing network, useful information includes a network diagram, an access point list, client device models, application descriptions, and the times when problems occur. Before estimating the work, we agree which missing data our team can collect on site and which materials the customer must provide.

05What will be in the final report?

The report contents are agreed in the task specification before work begins. They may include the survey program, measurement conditions and routes, maps and tables for agreed parameters, identified limitations, conclusions, and recommendations within the task scope. Raw exports, editable files, photographs, and additional test results are supplied only if included in the agreed deliverables.

06Will the survey show the source of any interference?

Not necessarily. Standard Wi‑Fi measurements may reveal interference or its effects without identifying its type, location, or physical source. If separate spectrum analysis is required, we first confirm the available methods, equipment, conditions, and limits of the result. Until verification is complete, the report distinguishes observations, engineering hypotheses, and confirmed conclusions.

The next step

Plan a Wi‑Fi site survey

Send a plan and specify the areas, measurement objectives, client devices, and access restrictions. We will review the inputs and propose the scope of work and deliverables.
