An Example of Step by Step Procedure

Let's assume that you have a wireshark log for the following case and think of a step by step analytic process : (This is a use caes example mentioned in previous section and a imaginary situation just to have some big picture about how the analystics goes on).

  • Retail Stores Customer Movement Tracking: Analyze the flow of customers through the store to identify high-traffic areas, optimizing store layout and product placement.
  • Engagement and Loyalty: Offer personalized promotions or information to customers based on their location within the store, enhancing customer engagement and loyalty.

Analyzing WiFi data for customer movement tracking and engagement in a retail store using Wireshark logs involves several steps focused on interpreting signal strength, device connections, and possibly, the use of management frames to understand customer behaviors. While Wireshark itself might not directly capture customer movement without specific network configurations, here's a conceptual approach to how you might analyze relevant data:

Now let's think of how we approach this in step by step.

Step 1: Set Up for Data Capture

  • Ensure that your WiFi infrastructure is configured to log detailed information about device connections and disconnections, signal strength, and access point (AP) interactions. This might involve setting up multiple APs throughout the store to capture data across different zones.

Step 2: Collect Wireshark Logs

  • Capture Wireshark logs during a typical business period or during a specific event/promotion. Focus on capturing management frames, which include device association, reassociation requests, and probe requests/responses that can indicate the presence and movement of WiFi-enabled devices.

Step 3: Filter Captured Data

  • Filter by MAC Addresses: Start by filtering the data for MAC addresses that correspond to customer devices. This can be challenging due to MAC address randomization for privacy, but patterns may still emerge.
  • Probe Requests: Filter for probe requests, which are sent by devices seeking WiFi networks. These can indicate when a device enters or moves within the store.

Step 4: Analyze Signal Strength and AP Connections

  • Signal Strength Analysis: Analyze the signal strength (RSSI) of probe requests and associations to gauge how close devices are to specific APs. This data can help identify high-traffic areas.
  • AP Interaction: Look at which APs devices are connecting to and how often they switch between APs. This can give insights into movement patterns within the store.

Step 5: Time and Duration Analysis

  • Analyze the timestamps of first and last appearances near APs to estimate the duration of visits and identify peak times. Duration near specific APs can indicate interest in particular store areas.

Step 6: Map Data to Store Layout

  • Using signal strength and AP connection data, map device movements to the store layout. This requires knowing the physical location of each AP and interpreting signal strength as an indicator of proximity.

Step 7: Identify Patterns and Insights

  • Look for patterns such as common paths through the store, areas with prolonged dwell times, and times of day with increased activity. These patterns can inform store layout optimizations and targeted engagement strategies.

Step 8: Implement Findings

  • Use insights to adjust store layouts, product placements, and to plan targeted promotions. For example, if certain areas show high traffic but low engagement, consider changing product placements or signage to increase interaction.

Step 9: Personalized Engagement Strategies

  • While Wireshark data alone may not provide enough detail for personalized promotions without integrating with other systems (e.g., WiFi marketing platforms), insights on high traffic and engagement areas can guide where to place QR codes or NFC tags for promotions.

Step 10: Continuous Improvement

  • Regularly analyze Wireshark logs to monitor changes in customer behavior, effectiveness of layout adjustments, and engagement strategies. Use this data for ongoing optimization.
