The present document specifies technical characteristics and methods of measurements for Robotic Mowers with inductive loop systems (RMI) below 148,5 kHz. The present document covers all Robotic Mowers that use guidance Inductive loop wire systems (RMI) using the frequency range below 148,5 kHz. An RMI system includes: • RMI docking station: charging stations for the robotic mower and the signal generator/antenna connecting point for the signals on the integral antenna and boundary wire. • Robotic Mower: receiving part inside the RMI. • Boundary Wire: user installed antenna. • Integral antenna: integral inductive antenna integrated inside the RMI docking station. The present document does not cover other devices using the frequency range below 148,5 kHz, e.g. ETSI EN 303 348 (Inductive loop for hearing impaired in 0 kHz to 20 kHz) [i.9], ETSI EN 303 454 (metal sensors) [i.10]. 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 0 Hz to 148,5 kHz Receive 0 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 2013/752/EU [i.2]. The present document covers the essential requirements of article 3.2 of Directive 2014/53/EU [i.3] under the conditions identified in annex A.
