In the article we calculated and discussed the energy cost for performing software updates in LPWAN networks LoRa, SigFox and IEEE-802.15.4g. The energy cost is determined for three different scenario's: 1) a full system update; b) an application update; c) a MAC update. In each scenario, different update methods are considered. The excel file contains the raw input data (first sheet) gathered from datasheets, standard specifications, as well as the transaction sizes in different scenario's using different update method. The transaction sizes were determined by examining the sizes of the object files and firmware in the different update scenario's and for the different update methods. The three other sheets contain the processed data presented and discussed in the article. The excel also contains VB macro's to calculate the energy consumption in the downlink for a particular transaction size (i.e. software update in our case) and technology. They are used in the last three sheets in the excel workbook.
