How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Number of Sensors = 20, Reporting Interval = 60, Message Size = 200, Active Hours per Day = 24 = 6 input(s) provided
  2. Calculate Data Usage
    Data Usage
    164.79 = 164.79
  3. Calculate Monthly Data Cost
    Monthly Data Cost
    0.8 = $0.8
  4. Calculate Total Reports/Month
    Total Reports/Month
    864000 = 864000
  5. Calculate Data Usage
    Data Usage
    0.161 = 0.161
