nRF9151 DECT NR+ Multi-hop Mesh Support in nRF Connect SDK

[AhmedMARNISSI]

Hi,

I am currently testing the dect_shell example on two nRF9151 DKs and achieved a range of ~500m. I want to transition this setup into a multi-hop mesh network topology to extend my range further.

1. Does the native nRF Connect SDK currently include an open-source multi-hop mesh routing layer for DECT NR+, or is it limited to a Star topology at the MAC layer?  

2. If I want full autonomous mesh routing, do I need to integrate the Wirepas 5G Mesh add-on, or is there a Nordic sample (like an updated Hello DECT) that demonstrates custom data relaying?

Thanks!

I guess that by "native nRF Connect SDK" you mean using the Nordic stack. If this is what you mean, then no, our current DECT NR+ MAC stack (v2.0.0) is limited to a star topology.

2. If I want full autonomous mesh routing, do I need to integrate the Wirepas 5G Mesh add-on, or is there a Nordic sample (like an updated Hello DECT) that demonstrates custom data relaying?

No, there is no "Nordic official sample" that explicitly uses the Wirepas stack. I've never tried their stack so I can't say this with confidence, but Wirepas probably has some samples available that show how to use their stack.

But I don't want to confirm anything on their behalf, so if you need more information on the Wirepas stack, please contact them directly.

Best regards,

Simon
