Hardware and platform constraints
A proximity integrator is not simply an IT contractor who happens to mount plastic discs on walls. The role demands a practical understanding of radio frequency behaviour in physical spaces—how Bluetooth signals attenuate through different building materials, how NFC tags perform on metal surfaces, and how QR codes hold up under venue lighting. When evaluating a partner, the primary distinction is their ability to bridge the gap between software requirements and the unpredictable physics of a real-world environment.
General IT integrators often approach a deployment by focusing on network connectivity and power, which are necessary but insufficient for proximity technology. A specialist proximity integrator will start by asking about the physical layout, the movement patterns of visitors, and the specific materials used in your construction. They understand that a beacon placed near a reinforced concrete pillar will behave differently to one suspended beneath a metal ceiling grid, and they plan accordingly rather than treating the hardware as a simple plug-and-play device.
Your evaluation should centre on whether the integrator can demonstrate a documented process for site surveys, signal mapping, and post-installation calibration. If their proposal jumps straight from hardware procurement to software deployment without detailing the physical installation and measurement phase, they are likely leaving the hardest part of the project to chance.
Supplier claims, testing and qualification
Retail and Venue Environments
In a retail setting, an integrator must demonstrate how they will define zones that align with actual shopper behaviour rather than an idealised floor plan. Ask how they account for movable objects such as stock cages, promotional end-caps, and metal shelving units that shift weekly. A competent integrator will propose a site survey methodology that includes on-site RSSI measurements at various heights and densities, rather than relying solely on predictive modelling software that cannot account for seasonal stock changes.
For large venues like arenas or conference centres, the consideration shifts to density management. The integrator needs to explain how they prevent beacon signal overlap in crowded corridors and how they plan the physical mounting to protect the hardware from accidental damage during event changeovers. Enquire about the specific mounting hardware they favour for different surfaces—adhesive mounts fail differently to mechanical screws, and the choice affects both maintenance access and long-term reliability.
Museums and Temporary Events
Museums present a distinct challenge: exhibits change frequently, and accuracy requirements are often tighter at a micro-level to distinguish between adjacent displays. The integrator should explain how they handle hybrid setups—combining beacons for passive zone detection with NFC or QR codes for precise, user-initiated interactions at a specific exhibit. They also need to address how the physical placement will be adjusted when an exhibition is refreshed without requiring a complete re-survey of the entire floor.
For temporary events, the infrastructure is inherently transient. The integrator must plan for rapid deployment, battery life constraints over a multi-day schedule, and complete removal without damaging the venue. Discuss their approach to testing the system under load; a setup that works in an empty hall on a Tuesday afternoon may behave differently when thousands of attendees with active Bluetooth devices are present on a Saturday.
What happens after procurement
The most frequent error in selecting an integrator is assuming that strong software development credentials translate to competent hardware deployment. An integrator might build an excellent campaign management interface but fail to account for how a crowded room full of bodies absorbing 2.4 GHz signals will alter beacon range. Software skills do not substitute for RF experience.
No integrator can guarantee precise indoor accuracy without a measured pilot in your specific environment. If a supplier promises exact distance measurements based solely on a floor plan review, treat it as a warning sign. Physical limitations—thick stone walls, glass partitions, reflective surfaces, and even the presence of water features—dictate the reality of the deployment. The right integrator will state these limitations clearly and explain how their placement strategy mitigates them, rather than promising perfection.
Before agreeing to a contract, verify a few practical points directly with the integration team:
- Documentation standards: How do they document beacon placement so your facilities team can locate a specific unit six months later? Ask to see a sample installation record.
- Maintenance handover: What is their process for identifying and replacing a failing battery without disrupting operations? Do they provide a clear schedule and inventory map?
- Calibration logs: Do they provide calibration data that your operational managers can actually read and use, or is the data locked inside their own proprietary dashboard?
- Interference handling: Ask them to describe a previous project where they encountered unexpected RF interference and how they resolved it on site.
The right proximity integrator will design a system that your operational team can maintain, monitor, and adjust. If their model relies on permanent dependency on their call-out service for basic tasks like battery changes or zone tweaks, the total cost of ownership will escalate quickly, and the system will become fragile the moment the contract ends.
