If it is an intentional radiator and operates above 9 kHz, it is considered to be a transmitter. If so, it is considered to be an inductive loop short range device in Europe and subject to EN 300330-1 and -2 for radio emissions and EN 301489-1 and -3 for spurious emissions and immunity. FCC Part 15 rules applies in the US and Industry Canada RSS-210 applies in Canada.
However, one might be able to construct a reasonable argument that the device is not an intentional radiator because the signal is inductively coupled to the mower and that any emissions outside the boundary is unintentional. The problem with the argument is that the loop and mower are not physically attached or in proximity all of the time.

Hello everybody! A friend of mine, overthinking of the breadth of my knowledge, is asking me for some advise about the applicable standards to a rather unusual piece of equipment. It is a "auto mower" intended to be programmed by the user to cut within a given garden area. It makes use of a boundary loop wire to exchange information (by means of RF TX-RX) about the actual position and the cutting area. It is provided also with a docking station where it goes automatically to recharge its battery. Now the questions. Is there any applicable product standard dealing with EMC and safety of that kind of devices? Do you think it is to be handled as an intentional RF transmitter, similarly to an ISM? Let's consider it is not an intentional transmitter, as the emission depends on the broadness of the reference loop, does it make sense to do measurement at three or ten meters? Do you think immunity as well can be anlysed regardless the actual installation? As my field of interest is bounded to electromedical devices and actually I have no garden to take care of, can someone out of there help my friend to send this problem to grass? Thanks in advance. m.p. ------------------------------------------------------------- ESAOTE S.p.A.
