In Europe there's not only power limitations but also duty cycle on some bands. Eg on 868Mhz you can only transmit 1% of the time.
I don't think the equivalent US band of 915Mhz has this, and it has a much higher maximum power which is really nice. Wish we had something like this here.
- vvanders 5y agoYep, you can see this if you go poke into LoRa and associated protocols. 915MHz does have some restrictions on either using spread spectrum, frequency hopping or much lower power limits so it's still quite different than say the ham bands.
- Terry_Roll 5y agoYes the Europeans give away some of their knowledge when looking at radio spectrums, the recent 5G bands causing problems with aircraft at airports in the US is one such example of forward planning or lack of.
- CraigJPerry 5y agoThere’s also listen-before-talk rules for devices in certain ISM bands in the EU. Affects at least LTE, Wifi and a few other users in 5.8ghz
- usrn 5y agoOur band around 400Mhz has a similar limitation.
