                 Data relevance
• 11498 messages handled (20040526102002 – 20041126090529 )
• Extracted data:
    Host time (UTC)  reception of the SMS by the HUB.
    OBT ID
    OBT generation time (TX time - UTC)  time the OBT
      did send the SMS.
    “User” (PI, SNCF, CP)
    Message type (0x80, 0x82, 0x84, 0x90 …)
    Power consumption
    Position time
    Event time

(cfr. Excel file “all.xls”)

      Message latencies (1)
• Host time (reception) – OBT generations time (send)
• Restrictions:
    Only (“single” record 0x84 messages);
    Valid Position & Event times;
    For PI OBT’s only (differences between CP, PI and SNCF
     OBT’s prove to be not significant);
    2850 records are useable data

   AVERAGE LATENCY:                   2496 seconds (42 minutes)
   MEDIAN LATENCY:                    63 seconds

                 SNCF

• Based on data in “sncf_power.xls”
   Maximum energy consumption per month = 85 units
    (approximately 1.83 %);
   Average power units used = 500;
   Energy units remaining: 4651 – 500 = 4151
