Hotel Wi-Fi site survey: a checklist before installation and at handover

A hotel Wi-Fi site survey is a measurement of signal and performance taken where guests and staff actually use the network. Before installation it decides where access points go and how they are cabled; at handover it proves the result room by room, with the doors shut, and leaves a file you can check later.

The invoice lists access points, the installer says coverage is fine, and the first complaint comes from the room at the end of the corridor. Nobody agreed in writing what "covered" means, so there is nothing to check the work against. After reading this you will know what to give the installer before the survey, where to test, what a handover test looks like, and what to keep in the file. The vocabulary, from access points to heat maps, is explained in plain words in hotel network and Wi-Fi terms explained.

What is a hotel Wi-Fi site survey?#

A hotel Wi-Fi site survey is a measurement of signal and performance taken in the places guests and staff use the network, not a count of access points. It happens twice: before installation to decide where equipment goes, and at handover to prove what was installed.

Two jobs share one name. A design survey, done before cabling, decides access point positions, cable routes and the channel plan. A validation survey, done at handover, measures the finished network against agreed criteria.

A predictive survey is software modelling from floor plans and wall materials. A walked survey uses a device and records readings point by point. Ask which one you are paying for, because they answer different questions: a predictive map describes the design, a walked map describes the building as built.

The output should be concrete: a coverage map (heat map), an access point map with labels, a channel plan, a list of cable runs and the raw readings behind the picture. If the deliverable is a single colourful image with no numbers behind it, ask for the readings.

One limit to understand early: a survey does not tell you how many guests will connect at the busiest hour, or whether the internet line is large enough. Coverage and capacity are separate questions, and line sizing is its own calculation, covered in sizing the internet line from rooms, guests and peak hours.

What should you give the installer before the survey?#

Give the installer the building as it is used, not just the floor plan: wall types, room counts, the areas that are not rooms, and how many devices are connected at the busiest hour.

Start with floor plans showing room numbers, plus a marked-up copy showing where guests actually sit: the far corner of the terrace, the pool bar, the lobby sofa area. Then describe wall and ceiling construction. Drywall, brick, concrete, plumbing shafts, fire doors and mirrored or tiled walls all change how far a signal travels, and therefore how many access points a floor needs.

Give room counts by type and the peak number of connected devices. That number is different from the guest count: phones, laptops, tablets, room televisions, staff handsets and payment terminals all count. Then list the areas beyond the rooms: meeting rooms, restaurant, spa, gym, pool deck, terrace, basement staff areas, stairwells and lifts.

Finally, state the constraints an installer cannot see from a plan: heritage or listed building rules, surfaces that cannot be drilled, cable routes that already exist, and where a technician can reach a ceiling hatch. Include the existing internet line and router details, and who owns that contract.

Access points in rooms or in corridors: which should you choose?#

It depends on what stands between the access point and the guest. A corridor access point is cheaper to cable, but its signal must pass a wall and often a fire door; an in-room access point sits closer, but costs more cable and more devices to manage.

The question to ask the installer is this: how many walls, and which walls, stand between each access point and the far corner of the furthest room it serves. Ask for the answer drawn on the plan, not spoken. Wall material decides the answer: a stud partition and a concrete shear wall are not the same obstacle, and a shaft carrying pipes and ducts is worse than either.

A corridor design means fewer devices and one cable run per floor, but neighbouring units interfere with each other, and corner rooms and bathrooms sit furthest from the signal. An in-room design puts at most one wall between the access point and the guest, but requires cabling into every room, more devices to configure and replace, and a maintenance plan for units inside guest space. Mixed designs are common: in-room units in the room wings, ceiling units for lobby, restaurant and meeting rooms.

There is no universal ratio. Any "one access point per so many rooms" figure is a starting estimate and must be labelled as an example, then checked by measurement. For example, a figure of one unit per six rooms is only a first guess for a concrete building with dense walls; the survey exists to replace the guess.

Where should the survey and the handover test cover?#

Everywhere a guest or a staff device is used, which is more than the guest rooms. The places that fail are usually the ones nobody wrote down.

Prioritise the rooms where the signal has travelled furthest: end-of-corridor rooms and corner rooms. Include stairwells and lift lobbies, and inside a lift car if the hotel advertises coverage there. Cover basements, spa, gym, staff corridors and back offices, where staff devices and payment terminals run.

Outdoor areas need their own test points: the pool deck and terrace, including the far corner where guests sit, and the effect of a closed glass door between indoor and outdoor areas. Meeting rooms and ballrooms should be tested empty and again with a full room, because a room full of people absorbs signal. Test the restaurant and bar at service time, where handheld order devices and card terminals compete with guest devices for the same network.

What does a handover test look like?#

A handover test is a walk of the building, room by room, with the same device and the same test, with the doors shut, recorded on a form you keep.

Agree the criteria before work starts: what counts as a pass in a guest room, in a public area and on a video call. Write the criteria and the test locations into the contract, so the price and the acceptance refer to the same work.

Doors shut. A reading taken in a corridor with bedroom doors open flatters the result, and the guest is behind a closed door. Use the same device, the same test tool and the same time window, and note the device model and software version, because readings are not comparable across devices. Test at a busy hour as well as an empty one, and record how many devices were connected during the test.

Roaming is part of the test: walk from the lobby to the room without dropping a call or a video stream. A device that clings to a distant access point is a common and invisible failure. Record every failure and the fix, then re-test only the failed locations after the fix, not the whole building.

When a guest later reports a problem, this table is your baseline. The front desk routine for that moment is described in guest Wi-Fi complaints: a front desk troubleshooting checklist.

What should be in the file you keep?#

The file is the difference between a network you can maintain and one you have to survey again from scratch. Ask for it as a deliverable in the contract, not as a favour after the invoice.

Passwords and administrator accounts must be in the hotel's name, with a note of who may change them. The handover test results should carry the date, the device used and the criteria applied, so a later complaint can be compared against a baseline rather than a memory.

When should you survey again?#

Survey again when the building, the devices or the complaints change, not only when the network stops working.

After a renovation or a change of walls: new partitions, a new meeting room, a converted floor, a roof over the terrace. When the use of a space changes: a restaurant turned into a co-working lobby, a seasonal pool bar, a new conference layout. After a change of internet line or router, which can reshape the network even when coverage has not moved.

Survey when complaints cluster in the same rooms or the same hours. Measure before buying hardware, because the cause is often a wall, a channel setting or a line that is too small. Also survey on device turnover: new handheld terminals, new room televisions, new payment devices, a property management system running on tablets. After major firmware or configuration changes, re-test the sample rooms rather than the whole building.

What to do next#

Before you sign the quote, ask three things in writing: whether the survey is predictive or walked, which rooms and areas will be tested at handover, and what file you receive at the end. Put the acceptance test and the test locations into the contract, because coverage is only a promise until someone measures it room by room with the doors shut.
