Simulatore dell'impatto della randomizzazione MAC e dell'integrità dei dati

Simula come la rotazione del MAC del dispositivo influisce sulle analisi del WiFi per ospiti e modella la riconciliazione dei dati.

Simula l'impatto della randomizzazione MAC

1. Venue profile type

Choose a template that matches your venue footprint.

Large physical footprint, high pass-by count from adjacent streets, long dwell times, high return rate.

2. Ground truth footfall

Actual number of unique human visitors entering the venue per day.

3. Visitor return rate

40%

The percentage of daily visitors who have visited this venue previously.

4. Private address rate

80%

Percentage of visitor mobile devices running iOS 14+ or Android 10+ with MAC randomization enabled.

+62%Raw Device Count Inflation

Without deduplication, raw probe sensors count rotated MAC addresses as new unique devices. In this scenario, raw logs record 24,240 devices, inflating your actual footfall of 15,000 guests.

Operational impact of data skew

Over-budgeting staff: Planning shift patterns based on raw device counts leads to over-staffing due to duplicate counts of rotated MAC addresses.

Skewed conversion rates: If visitor counts are artificially high, retail metrics like sales conversions (transactions / footfall) appear artificially low.

Undervalued loyalty: True returning visitors are masked, leading to poor customer loyalty tracking and inaccurate lifetime value modeling.

How Purple resolves address rotation and restores data integrity

Purple mitigates MAC randomization errors at the software layer by correlating signals across multiple touchpoints. When a user logs in via the captive portal, their account is anchored to their profile. Even if the device rotates its MAC address, subsequent logins are stitched together using session variables, browser cookies, and passive RF signatures. This cross-referencing corrects the database inflation, providing venue operators with accurate footfall, return frequencies, and dwell analytics.

Comprendere la rotazione per la privacy e l'accuratezza dei dati

I moderni sistemi operativi mobili randomizzano regolarmente gli indirizzi MAC per proteggere la privacy degli utenti. Sebbene sia vantaggioso per la sicurezza, questo comportamento distorce le analisi offline dei locali gonfiando il numero di visitatori e riducendo i tempi di permanenza. Questo simulatore dimostra come i dati grezzi vengano distorti e come Purple riconcili questi segnali.

Parametri chiave simulati

Tasso di inflazione del conteggio dei dispositivi grezzi dovuto alla rotazione degli indirizzi.
Duplicazione dei visitatori di ritorno conteggiati come ospiti alla prima visita.
Riconciliazione dei dati tramite accessi al portale captive e cookie stitching.

Struggling with data accuracy?

Address rotation on iOS and Android can inflate raw footfall metrics. Purple reconciles guest signals through multi-source correlation, restoring analytics integrity.
