Slide 4: Agenda
© Nordic Semiconductor Agenda = NR+: What is it and why should | care? =" Targeted applications and benefits =» NR+: How? » Upper layers, no physical stuff oF = Status of the standard = Status of the Implementation » Q&A
Slide 5: The What: NR+, aka DECT-2020 NR
Slide 6: Why DECT NR+
© Nordic Semiconductor Why DECT NR+ " Opportunity to use existing spectrum allocation = Utilizing existing cellular technology = New radio standard dec
Slide 7: Targeted applications
Targeted applications Made for massive loT networks and low latency communications 1. Massive loT » Networks of thousands of nodes = Use case: Smart energy, smart city applications 2. Low latency communications = Latency 1ms » Use case: Speech and audio, automation control
Slide 8: DECT NR+

Slide 11: Vocabulary
© Nordic Semiconductor Vocabulary Sink Leaf Leaf ea Leaf Leaf Leaf Leaf Star Synonyms Sink Leaf Router Router Router Leaf Leaf Leat Tree-Mesh 1. Sink = Gateway / Border Router 2. FT = Relay Node / Router Node / Parent Node 3. PT = Leaf Node / Node / Child Node “A mesh network is a local area network
Slide 12: Network protocol layers
© Nordic Semiconductor Network orotocol layers =" Convergence (CVG) layer: Application multiplexing *" Data Link Control (DLC) layer: Routing, segmentation = Medium Access Control (MAC) layer: Radio resource control = Physical (PHY) layer: OFDM, HARQ, etc.
Slide 13: NR+: Convergence (CVG) layer and Data link control (DLC)
© Nordic Semiconductor NR+: Convergence (CVG) layer And Data link control (DLC) = CVG Provides application layer data identification and multiplexing between multiple applications = Mesh E2E security roston = DLC provides transport service selection = O Transparent » J Segmentation = 2 ARQ = 3 Segme
Slide 14: DLC: Network routing
DLC: Network routing Sink Up: To sink Leaf = Forward to parewnt until it reaches sink Router = Sink can forward to internet Router Router
Slide 15: DLC: Network routing
DLC: Network routing = Down: Flooding oF ink, f Il child rel . rom sink, forward to all child relays Sink = Relays forward to child relays = Relay that has the destination as a direct leaf sends only to that leaf Leaf Router Router = Flooding with hop limit also for Node-to- Node communication a -.
Slide 16: NR+: MAC layer
NR+: MAC layer Central, lots of features in MAC for the radio resource control Application A Big Sepication 6 Broadcast / multicast / unicast Dedicated resource or random access Radio addresses Routing service * 32bit network wide address DLC entity set » 16bit cluster (link) address Beacons for rad
Slide 17: MAC: Radio Channel Resource Control (RRC)
© Nordic Semiconductor MAC: Radio Channel Resource Control (RRC) RAD i Relay, a routing FT device, manages radio resource with Beacons » Every beacon period need to scan channel, update reservations for next beacon «= Allocating TX time for leafs in beacons Leaf follows relay beacon = Following the
Slide 18: RRC: Beacon is the basis
RRC: Beacon is the basis Paging to leafs for downwards traffick | Frame is 10 ms Beacon Allocated RACH Dedicated flow (or legacy DECT) 1. Send own window for detected on scanning the channel 2. Listen parent relay leafs upwards during previous Beacon period traffick
Slide 19: RRC: Power optimization of beacon
© Nordic Semiconductor RRC: Power optimization of beacon Frame 1 Frame 2 Extreme power save, Frame... low data, long latency [rrameroo | | | | TTT TTT TITI TI ttt tt ttt) Beacon period can be from 10 ms to 32 secs Frame 1 Frame 2 Frame 3 Moderate power save Frame .. moderate data, low latency Frame

Slide 21: Dedicated flows
© Nordic Semiconductor Dedicated flows = leaf makes an association / modification stating the needed dedicated flow resource Sink ‘eserve =» How many slots, period, what is the validity period for reservation = relay verifies the capacity exists and Leaf Leaf acknowledges Leaf = Dedicated flow slots
Slide 22: Status of the standard
Slide 23: Standard approach
© Nordic Semiconductor Standard approach » DECT NR+ standard defines features " Profile is the selection of features for specific application needs e e@ @& es A ~ ad s = No general interop standard, a 2 application / device specific networks & a & e bd @eeee (c) Lego, they are just great
Slide 24: Standard status
Standard status = Core standards are approved by ETSI and ITU, 24 February 2022, now version 1.4.1 = Overview ETSI TS 103 636-1 = Radio requirements ETSI TS 103 636-2 = PHY ETSI TS 103 636-3 = MAC ETSI TS 103 636-4 » DLC and CVG ETSI TS 103 636-5 =» Working on =» Harmonized test specification EN 301
