Smart Wi-Fi for Malls, supermarkets, and retail

Guest Wi-Fi in a mall: what the centre gets

Shopping malls attract thousands of visitors daily, making the guest Wi-Fi network a valuable resource for marketing and analytics. The TheLink cloud platform allows consolidating all access points of the mall into a single managed network with detailed statistics. You get the opportunity to monetize Wi-Fi by displaying tenant ads on the welcome captive portal.

The collected Wi-Fi analytics (device MAC addresses) help analyze visitor behavior: track dwell time, visit frequency, peak hours, and paths between floors. This data is critical for optimizing rental rates and planning mall marketing campaigns.

Integration with the Aitu Passport national digital ID removes the per-confirmation cost: instead of paying an operator for every SMS, sign-in takes a second and does not depend on message delivery. At thousands of visitors a day this becomes a noticeable saving for mall management.

What authorization gives a mall beyond meeting the requirement

For a shopping centre the sign-in portal is the one place where an anonymous stream of visitors turns into measurable numbers. Door counters count passages, but they cannot tell one person who came in four times from four different people. Wi-Fi session data answers different questions: how long people stay, what hours they arrive, how often they return, and what share of the audience is visiting for the first time.

Those numbers feed straight into conversations with tenants. Rent is negotiated around footfall, and the argument that a given number of people pass a particular unit on weekdays and another number at weekends, with a stated average visit length, carries more weight than an overall figure for the whole building. The same portal doubles as ad inventory: every person connecting sees the tenant's banner, and that space can be sold.

How the network of a large site is built

A mall differs from a café not in the number of access points but in the fact that several networks run inside it. Payment terminals, video surveillance, operational comms and guest Wi-Fi must not overlap. The guest segment is separated out and given access to the internet only, with no route to internal resources. The portal connects to the controller — Cisco, Aruba, Ruckus, TP-Link Omada or UniFi — and authorization runs over RADIUS, the standard method for that class of equipment.

The load profile is different too. At weekend peaks thousands of devices are active at once, and the spike falls not on traffic but on the number of authorization attempts, because people enter the building in waves. The cloud side is sized for that profile, and a brief loss of the provider link does not drop sessions that are already authorized.

Personal data and reporting

A guest’s phone number is personal data, and it may only be collected with consent given explicitly on the sign-in page. What tenants receive is not contact details but anonymised statistics: visit counts, distribution by hour, the share of new visitors. It is worth writing that separation into the tenant agreement up front — it tends to be the clause people remember later than they should.
