Note 1: These figures are derived from the component data sheets including the Telit Hardware User Guide. Per Telit, “The reported values are an
average among all the product variants and bands for each network wireless technology.” Results can vary depending network conditions.
Note 2: Power consumption figures are with on-board Status LED disabled.
