DECT NR+: A technical dive into non-cellular 5G

Greeting for the day.

I appreciate your support.

I currently have a DECT NR+ setup running on the nRF9151, based on the HELLO DECT PHY sample using nRF Connect SDK v3.3.0preview2. I am seeking your guidance on how to route data across a small NR+ cluster, specifically in the following topology:

[cluster1] Leaf (Node1) ⇄ Router (Relay) ⇄ Leaf (Node2) [cluster2]

Could you please advise on the correct approach, configuration, or APIs required to enable multi‑hop data routing between Leaf nodes through the Router?

Thank you.

In a star network, silk nodes only communicate with leaf nodes. Can their latency be controlled within 1ms at any time?

"Another thing to note is that DECT NR+ defines many of its core features, like routing and re-transmitting packets, on the radio stack level."

Is HARQ implemented entirely in the PHY layer?

"Since relay devices manage the radio usage in their cluster, they can tell leaf nodes when the relay device can be reached for uplink data forwarding, allowing relay devices to sleep outside of this period. The relay devices page the leaf nodes in beacon messages, telling the leaf when it must listen for downlink data. The leaf node only needs to listen to beacon messages, which can have a beacon period varying from 10ms up to 32s. This allows the network to choose between very low latencies or allowing devices to sleep to save power."

Is this statement something I can find in the DECT NR+ specifications? Does it have any relation to RACH duty cycles?

can you please give us the characteristics of the communication ( range, throughput, etc.)?

What are the different node types in a DECT NR+ network and what functions do they serve within the network topology?
