The radio frequency spectrum is regulated by designated regulatory authorities that definehow specific spectrum bands can be used. As each frequency band has its strength, WürthElektronik eiSos provides for each frequency band proprietary radio modules, which allowenergy efficient and fast data transmission.
With the evolution of radio chips, new proprietary radio modules have been developed, thatare more energy efficient during data transmission and reception. Furthermore new codingand modulation techniques have been added, that allow higher transmission ranges (longrange mode) and/or higher data rates.
Due to this natural evolution, when redesigning a device that is already using a proprietaryradio module, it is recommended to use the latest member of the corresponding radio mod-ule family.
This application note describes the key factors to be considered, when replacing a pro-prietary Würth Elektronik eiSos radio module with its successor from the same family
If a switch from 868 MHz to 915 MHz is desired to serve also the North Amer-ican market, the application note ANR015 "FROM 868 MHZ TO 915 MHZ" describes the necessary steps to be performed.
