ETSI ETSI EN 303 447 V1.1.1 (2017-09) 6 Introduction The present document covers Robotic Mowers with Inductive loop systems (RMI) using th
29、e 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 insta
30、lled antenna. The present document is structured as follows: Clauses 1 through 3 provide a general description on the types of equipment covered by the present document and the definitions, symbols and abbreviations used. Clause 4 provides the technical requirements specifications, limits and confor
31、mance relative to transmitter and receiver. Clause 5 specifies the conditions for testing of the equipment and interpretation of the measurement results with the maximum measurement uncertainty values. Clause 6 specifies the required measurement methods. Annex A (informative) provides the relationsh
32、ip between the present document and the essential requirements of Directive 2014/53/EU i.3. Annex B (normative) provides necessary information on used test sites and procedures. ETSI ETSI EN 303 447 V1.1.1 (2017-09) 7 1 Scope The present document specifies technical characteristics and methods of me
33、asurements 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 0 Hz to 148,5 kHz Receive 0 Hz to
34、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 does not cover other devices using the frequency range below 148,5 kHz, e.g. ETSI EN 303 348
35、i.9 (Inductive loop for hearing impaired in 0 kHz to 20 kHz), ETSI EN 303 454 i.10 (metal sensors).
