DECT ULE Technology Overview

DECT / ULE Overview

DECT ULE is a mid-range low power consumption technology intended for battery or line powered home and industrial automation devices

Developed by the ETSI Technical Committee DECT, and built on top of DECT technology, addresses different market • Different players, different distribution channels

Suitable for many IoT scenarios, • Smart Home is the most mature and the primary commercial target from

current product manufacturers

• Synergies with DECT voice products and role of the Home Gateway

DECT / ULE Overview

1) Reuses the DECT spectrum

• License exempt “high-quality” spectrum (1 880 1 900 MHz)

2) Reuses DECT Physical layer and channel structure

• Range 70 m (NLOS) – >500 m (LOS) (= full DECT range)

• Low cost DECT hardware that can be shared with voice service

• Complete reuse of radio chipset in Base Stations and Home Gateways

• Size of DECT technology: 100 M of devices / year

3) New MAC layer specific of ULE

• New MAC messages and ultra-fast “expedited” procedures allowing combined transmission of signaling and U-plane data in the same packets.

• Provides reliable transmission at MAC layer and protects the integrity of the transmission

• New channel selection strategy (compared to DECT)

• New Management algorithms for handling access collisions

7

DECT / ULE Overview

4) Improved DLC and NWK layers

• Provides full C/O service with Mobility Management (similar to a cellular technology)

5) State-of-the-art security based on CCM authenticated encryption (RFC-3610) and AES-128

• Provides simultaneously strong encryption and continuous mutual authentication without the need of running NWK layer transactions

• Mechanism ideal for the intended application

6) Interface to upper layers based on IPv6 and 6LoWPAN • RFC currently in draft stage (draft-ietf-6lo-dect-ule-04):

• Similar and compatible approach to other technologies (IEEE 802.15.4)

• Provides technology transparency to application protocols

• Direct Interworking to Application protocols, or transport of other NWK protocols are also possible

DECT / ULE Market positioning

Market positioning and value proposition

• Optimal combination of power consumption and range • “best in town” for the specified coverage range (70m – 500m)

ETSI standards overview

ETSI Standards Overview

EN 300 175-1 to 8 • Basic DECT library split by layers

• All ULE procedures have been added to current revision (v2.6.1)

TS 102 939-1: DECT ULE Phase 1 • Defines the core of ULE technology

TS 102 939-2: DECT ULE Phase 2 • Adds multicast services, integration voice/data, SUOTA (Software

Upgrading Over the Air) and other improvements

An IETF RFC will define the Interworking to IPv6 using 6LoWPAN compression techniques • draft-ietf-6lo-dect-ule-04: Transmission of IPv6 Packets over DECT

Ultra Low Energy

Radio harmonized Standard shared with voice DECT • EN 301 406 and EN 301 908-10 for IMT-2000 band

Markets and Applications

ULE: target phase 1 applications

Smart Home and smart living applications • (All these applications are supported by current version of the standard)

1) Home automation and energy control

• Remote switches, dimmers and push buttons

• Smart Appliance control

• Smart metering and energy control

• Remote controls

2) Temperature control

• Thermostats, control modules and associated actuators

3) Security and Alarms

• Fire, Glass Break, Flood, CO2, burglary and other alarms

4) eHealth applications

• Medical Alarms / pendants (for elderly and vulnerable people)

• Medical monitor devices (I.e. Heart Rate or blood preasure Monitor)

ULE: phase 2 and beyond applications

Additional smart Home applications • Applications with mixed data / voice capabilities

• E,g. Intercoms and pendants with audio capabilities

• Multicast communications and wireless relay stations

Office and Industry automation • Introduction of large multi-cell systems with full mobility

Smart Cities • Short range radio for local communications and metering

• Local communication for security and critical services

Personal Area Networks (WPAN) • Local communication and wearables.

Increased data-rate applications • Extension up to 5 Mbit/s possible with current DECT technology

17

Evolution and standardization needs

18

Identified gaps and standardization needs in the immediate future:

Focused on the Smart Home scenario


Area 1: improvements and evolution of the core radio technology • Base technology will be improved by means of additional ULE phases

• Some identified items:

• Introduction of higher data rates and continuity between ULE and current high speed data capabilities

• Introduction of additional features required by several scenarios: slow motion and still image transmission (video vigilance), reduced latency modes, improved low power voice modes, further reduction of power by Tx power control, etc.

• Further improvements in auto-configuration, pairing and system management

• Some improvements are already in progress: standard for ULE relay stations currently under final development at TC DECT.

19


Area 2: “Low Energy” Application Protocols • Application Protocol Suites designed taken into account the Real Needs

of the Smart Home environment

• Target: bringing the energy efficiency to network, transport, middleware, and application protocols

• Not many groups working in this field

• Examples of the real needs

• Realistic semantics (for the intended problem)

• Rational architectures providing the required flexibility (and not more)

• Efficient Network layer protocols providing the requiring addressing needs (and not more)

• Efficient coding of the protocols

• Availability in a realistic time frame

20


Example • Alarm theft sensor powered by a Lithium battery CR2032

• Target: 5 years battery duration

• Application is not trivial from security point of view: requires continuous exchange of “stay-alive” messages to verify the integrity of the sensor.

• Such application is possible with DECT ULE

• However requires some cooperation (efficiency) from the application protocols

21


Example 2 • Medical pendant device for elderly vulnerable people

• Market and social importance not in discussion

• Current not-standardized implementations suffer from several radio, performance, and reliability limitations.

• It would be highly desirable adding voice capabilities

Medical pendant scenario

Summary and Conclusions

Ultra Low Energy: Summary

Summary and conclusions

DECT ULE is an state-of-the-art low power radio interface suitable for Home, Personal and Wide Area Networks

Offers an optimal combination of range and power consumption • Optimal range for Home Automation Networks, office and industry automation and

Personal Area Networks

• Reuses DECT radio interface and chipsets, already integrated in Home Gateways

Offers reliable service with MAC and DLC protection and full NWK layer with Mobility Management and Call Control • State-of-the-art security: CCM encryption with AES-128

Technology under ETSI full control: easy to expand to fulfill European needs

DECT ULE should be part of any European Large Scale Pilot project in the areas of smart living, smart Cities, Industry automation and wearables
