01
Observe before selecting.
Cisco’s Wi-Fi survey preparation covers applications, client devices and site plans. A predictive plan remains different from an on-site measurement. This guide extends the documentary preparation method to different building systems.
Start with a checkable sentence: who needs to do what, in which zone and when? “Improve the network” is too broad. “Let the reception team use its applications during peak hours” identifies a situation to investigate. Record what happens now, what needs to change and who can confirm the result.
Prepare one sheet per zone with a stable identifier, date and survey owner. Reuse that identifier in photographs and questions. Separate observations, statements made by a contact and remaining assumptions. This helps prevent a provisional estimate from becoming an accidental ordered quantity.

A record that keeps the context.
Scroll the table horizontally to compare all three columns.
| Record | Useful format | Question to resolve |
|---|---|---|
| Zone and use | Plan reference, users, hours and expected function. | Do uses change by day or team? |
| Visible existing equipment | Readable model, observed quantity, location and authorised photograph. | Will this item be retained, moved or replaced? |
| Connections and positions | Start, end and assumed route, without inventing a length. | Who confirms the route and installation conditions? |
| Operating constraints | Occupied areas, permitted access and proposed work windows. | Who authorises work and informs users? |
| Unknowns | Specific question, person responsible and next step. | Does the answer block the design or only an option? |
03
Prepare a visit that answers questions.
Before travelling
Request an available plan, the on-site contact and the main objective. Confirm accessible rooms and photography rules. Prepare a short list of questions the visit must answer; an inaccessible zone must remain recorded as inaccessible.
During the walkthrough
Follow the plan’s identifiers. Photograph only authorised equipment and positions, avoiding people, work screens, badges, passwords and confidential documents. An overview explains location; a detail photograph records a model when readable.
Before leaving
Review open points with your contact. Distinguish something genuinely absent from something merely not visible. Confirm who provides missing information and which document will be authoritative. Do not restart equipment just to complete a form.
After the visit
Organise photographs and notes by zone, remove unnecessary duplicates and share a short summary with the relevant contacts. Date and attribute corrections. Keep the old version if it has already been used to prepare an offer.
04
Example: reception and two work areas.
ILLUSTRATIVE EXAMPLE
Fictional case: a manager is preparing network improvements across three zones. The technical room is locked on the visit day; no internal inventory is confirmed.
Record facts
Assign Z01, Z02 and Z03. Record stated uses and visible positions. Add Z04 for the technical room with “not visited” status. The lack of an interior photograph does not mean there is no equipment.
Create the next action
Ask the site manager for an accompanied Z04 visit. Network design remains conditional on the inventory and necessary checks. Share the available brief without presenting a final switch or access-point quantity.
Update without erasing
On the second visit, add confirmed models and issue the next brief version. List changes and identify resolved assumptions. The first visit remains traceable, while the agreed version becomes the basis for the enquiry.
This example organises information. It does not size radio coverage, cabling or power, or authorise any intervention.
05
The minimum handover pack.
A plan and a key
Include the plan version, zone identifiers and a shared key. Clearly state when a plan is approximate. An annotated image can frame discussion but does not replace a validated dimensional survey.
An open-question register
For each question, record impact, answer owner and status. “Length to be measured” is useful; an empty field is ambiguous. Unconfirmed information should remain visible in the quotation request.
A decision list
Separate customer wishes, design proposals and decisions actually accepted. Name who can decide on an alternative. A preference expressed during a visit should not be presented as an order.
06
Identifiers that remain useful after installation.
Fluke Networks explains the value of retaining test results and linking cable labels with documentation. Consistent identifiers from the initial brief help preserve that continuity.
Keep a brief change history: room added, use changed, retained equipment or route to reconsider. The pack should let someone who missed the visit understand the request and its limits. Before sharing, check that photographs may be shared and that files carry a clear date and version.
07
Common questions before the visit.
Can I begin without a plan?
Yes, with a dated sketch and consistent identifiers. Mark unknown dimensions and request a usable design plan. Do not infer cable lengths from an image without a scale.
Are photographs enough?
They support the brief but may not explain use, access rights or constraints. Add a caption and a question when the image is inconclusive.
What if a model cannot be read?
Describe location and appearance without inventing a model. Ask the owner for authorised identification or an existing document.
Who validates quantities?
The design team reconciles observations with requirements and constraints. A quantity observed on site describes existing equipment; it is not automatically a purchase quantity.
How should an inaccessible area be handled?
Record “not visited”, identify the impact and plan an action. An offer may state this reservation, but the area must not be reported as verified.
08
A survey the team can use without you present.
Give each observation an identifier and use it in photographs, drawings and questions. An unmeasured dimension stays unknown. This fictional register is a starting point for your visit.
Scroll the table horizontally to compare all three columns.
| Observation | What is established | Question and next evidence |
|---|---|---|
| OBS-01 · main entrance | Two doors visible on annotated drawing V1. Opening direction recorded; width unmeasured. | Have openings measured and confirm uses with the owner; attach the answer to OBS-01. |
| OBS-02 · existing rack | Authorised front photograph and legible model references recorded. No passwords photographed. | Obtain the authorised inventory and configuration; unused ports do not establish available PoE power. |
| OBS-03 · cable route | Proposed route from A to B includes an inaccessible section. Total length remains unconfirmed. | Identify the access approver, surveyor and brief-update point; retain the uncertainty in the quotation brief. |
