Define compatibility and environmental needs
Hiring an integrator for a proximity or indoor navigation deployment is not the same as engaging a software supplier. Beacons, NFC tags and indoor positioning systems are physical infrastructure installed in real spaces, subject to radio interference, footfall patterns, building materials and changing layouts. The integrator you choose will determine whether your hardware performs as intended or sits on walls generating unreliable data.
The right questions expose whether a prospective integrator understands the operational realities of Bluetooth Low Energy (BLE) signal behaviour, calibration, maintenance access and the constraints of your specific venue. Many firms can mount beacons and configure a dashboard; fewer can explain why RSSI readings shift when a retail display is moved or why a museum gallery with stone walls needs a different placement strategy than an open-plan conference hall.
Your questioning should focus on three areas: how the integrator approaches the physical site, how they handle the gap between a pilot and a full rollout, and what they leave behind when the project is signed off. The answers will tell you whether you are hiring a partner who will reduce your ongoing operational burden or a contractor who disappears once the invoice is paid.
Mounting, configuration and platform fit
Site survey and signal behaviour
Ask the integrator to describe their site survey process in detail. A competent answer will mention walking the venue with scanning hardware, measuring RSSI at multiple points, identifying sources of 2.4 GHz interference such as Wi-Fi access points and microwave equipment, and noting building materials that attenuate signals differently. If the response skips straight to a floor plan and a beacon count, that is a warning sign.
Specific questions to put to the integrator:
- How do you account for different building materials in your placement plan?
- What scanning equipment do you use during the survey, and do you share the raw readings with us?
- How do you handle areas with high pedestrian density where the human body absorbs BLE signals?
- What happens if your initial placement plan does not produce the expected accuracy in our environment?
Calibration methodology
Calibration is where deployments succeed or fail. Ask the integrator how they calibrate each beacon after physical installation and whether they use a measured environment rather than relying on manufacturer defaults. The useful follow-up is whether they document the calibrated transmit power and advertising interval for every unit, so your team can reproduce the process later.
- Do you calibrate beacons in situ or rely on factory settings?
- What distance-to-RSSI model do you use, and have you validated it in a space similar to ours?
- How many measurement points do you use per beacon during calibration?
- Will we receive a calibration report for each installed unit?
Pilot design and evaluation
For retail and museum environments, a pilot is standard before committing to a full deployment. The questions here should establish whether the integrator designs pilots that produce genuinely useful evidence rather than simply demonstrating that beacons switch on.
- How do you define success criteria for the pilot, and who owns those criteria?
- How long does the pilot run, and does that period include representative footfall patterns such as weekends or event days?
- What metrics do you capture during the pilot beyond simple beacon detection counts?
- What does the pilot-to-full-rollout decision process look like?
Battery management and maintenance handover
Beacon batteries deplete, and the rate depends on the advertising interval and transmit power chosen for your specific deployment. The integrator should be able to explain the expected battery life under your configured settings, not quote a generic manufacturer figure based on ideal conditions.
- What battery life do you estimate for our chosen configuration, and how did you calculate it?
- How do you label and record each beacon so our facilities team can identify units during replacement?
- What documentation do you provide to support our ongoing battery replacement schedule?
- Do you offer a monitoring service, or will we need to manage that separately?
Event and temporary deployments
For event organisers, the questions shift towards speed of deployment, temporary mounting methods and removal logistics. The integrator should demonstrate experience with venues where the layout changes between events or where infrastructure must be struck within hours.
- What mounting methods do you use for temporary installations, and how do you verify stability over a multi-day event?
- How do you handle re-mapping when floor plans change between events?
- What is your lead time for scaling from a small pilot to several hundred units?
Operational ownership and requalification
Assuming hardware expertise equals deployment expertise
An integrator may hold reseller status with a major beacon manufacturer yet have limited experience placing those devices in complex environments. Vendor partnerships are worth checking, but they do not substitute for evidence of completed deployments in venues similar to yours. Ask for specific examples rather than a client list, and probe what the integrator actually did on those projects. Installing fifty beacons in a warehouse is a different skill from calibrating navigation accuracy in a museum with multiple floor levels and thick internal walls.
Not pressing on accuracy claims
If an integrator promises a specific accuracy figure such as one or two metres without qualifying that claim, ask them to explain the conditions under which that accuracy was measured. BLE proximity is not GPS, and accuracy varies with device type, orientation, interference and the number of beacons in range. A trustworthy integrator will describe accuracy in terms of zones or confidence ranges and will explain what your visitors are likely to experience in practice.
Overlooking documentation and handover
The most common complaint about integrators is not the installation itself but what happens afterwards. Without proper documentation, your operations team cannot troubleshoot drift, replace batteries confidently or adjust placement when the venue layout changes. Before signing a contract, ask to see a sample installation report from a previous project. Check whether it includes beacon identifiers, physical locations, configured parameters, calibration readings and any known issues. If the integrator cannot produce this, they are unlikely to deliver it for you.
Ignoring the ongoing support question
Clarify what happens after the deployment is accepted. Does the integrator offer a retainer for adjustments, or is each change quoted separately? If a new exhibition requires repositioning twenty beacons in a museum gallery, what is the process and typical lead time? If the integrator expects to hand over completely, ensure your internal team or a separate maintenance arrangement is ready to take on that responsibility from day one.
Not verifying interference assessment
Some integrators treat interference as an afterthought. In reality, a venue with dense Wi-Fi coverage, Bluetooth audio systems or neighbouring BLE deployments can experience significant signal contention. Ask the integrator what steps they take to scan for existing 2.4 GHz activity before finalising placement, and what they recommend if interference cannot be eliminated. The answer should involve channel selection, power adjustment and potentially accepting wider zones rather than promising precision that the environment will not support.
Key checks before signing
- Request a sample site survey report and a sample installation handover document from a previous project.
- Ask the integrator to walk through a specific deployment problem they encountered and how they resolved it.
- Confirm who owns the calibration data and beacon inventory records after project completion.
- Establish whether the quoted price includes post-installation adjustments within a defined period.
- Verify that the integrator's proposed beacon model supports the advertising format and firmware features your platform requires.
The goal of these questions is not to find a perfect integrator but to find one whose approach matches the operational reality of your venue. A firm that gives detailed, qualified answers and acknowledges limitations is generally a safer choice than one that promises straightforward results for a complex physical environment.
