The present document specifies technical characteristics and methods of measurements for Robotic Mowers with Inductive loop systems (RMI) below 148,5 kHz. These radio equipment types are capable of operating in all or part of the frequency bands given in table 1. Table 1: Permitted range of operation Permitted range of operation Transmit 100 Hz to 148,5 kHz Receive 100 Hz to 148,5 kHz NOTE: It should be noted that the frequency range between 9 kHz and 148,5 kHz is EU wide harmonised for inductive Short Range Devices according to EC Decision 2017/1483/EU [i.2]. NOTE 1: The relationship between the present document and essential requirements of article 3.2 of Directive 2014/53/EU [i.3] is given in Annex A. The present document only covers RMI systems with antenna sizes smaller than 1,67 km, see CEPT/ERC/REC 70-03 [i.1], Annex 9. NOTE 2: The antenna size is described by the distance between those two points on the antenna that have the largest distance between them (e.g. for a rectangle shaped antenna the largest diagonal; for a circular shaped antenna the diameter).
