Thread fequency Europe vs. other places

Configuration Matter/Thread
1

Hello,

does the SkyConnect supprot 868MHz for thread in Europe? Is it configurable or does one have to pay attention to the model they are buying? (For example for Z-Wave I already bought once the US version instead of the Europe version, which of course was useless to me then…)

And if I bug this shutter switch for example, is there a simple way to know if it works over 868MHz or not? (I mean apart from contacting the support)

Since the Skyconnect shares the radio with Zigbee, I would assume it uses only 2450 MHz, but the only way to know for sure is to ask Nabu Casa.

Chip where the SkyConnect is based on does not mention 868MHz.

Thanks, yes you’re right, it seems it’s really just for 2450Hz:

EFR32MG21 devices are 2.4 GHz wireless SoCs

Too bad. 868MHz has significantly better range…

Thread does not support 868Mhz.
Zigbee Pro (not the normal zigbee!!!) does and Z-Wave too.

This link claims otherwise

but to be honest, the silabs chips, ti-chips, nRF52840 all only use 2.4

@WallyR is correct @francisp , the thread specification (which for whatever reason one is not allowed to share – what kind of open standard is that?!?!) does mention only 2540MHz is supported:

A Thread Interface for the Thread Link Type TL1 MUST conform to the 2450 MHz PHY specifications defined in Chapter 6 in [IEEE802154-2006]

A Thread Interface for the Thread Link Type TL2 MUST conform to the 2450 MHz PHY specifications defined in Chapters 10, 11, and 12 in [IEEE802154-2015].

Thread Interfaces MUST implement only the 2450 MHz PHY.

Thread Interfaces MUST implement only the specification applying to the 2450 MHz O-QPSK PHY.

I think it’s pretty clear. Too bad, 868MHz has clear advantages.
