- punkgeek 7y agoooh. good to know. here's what we are doing now for the regions we know. Someone is sending in a PR soon for the extra 440ish band in EU soon. https://github.com/meshtastic/Meshtastic-esp32/blob/master/src/MeshRadio.h#L12 https://github.com/meshtastic/Meshtastic-esp32/blob/master/s...
- bigiain 7y agoIf you'd like some reference: https://www.acma.gov.au/step-2-show-your-product-complies https://www.acma.gov.au/step-2-show-your-product-complies Says: (2) The 900 MHz ISM band within Australia is 915–928 MHz. 900 MHz ISM devices working outside of this range cannot be operated in Australia (that is, ISM devices that use the frequencies 902–915 MHz are not authorised for use within Australia). (3) Using the frequency range 902–915 MHz would interfere with Australian mobile telephone networks. Severe criminal penalties, including fines of up to $255,000, exist under the Radiocommunications Act 1992 for interfering with radiocommunications services.
- ourlordcaffeine 7y agoI think it would be very helpful to other hobbyists if once you have worked out all the limitations in each country, to make a guide or infographic about all the rules and limitations.
- dfox 7y agoAnd in EU the whole 915MHz ISM band simply does not exist and is “the original GSM band” with the added caveat that there are some safety critical services inside the GSM's uplink/downlink guard band.
