ETSI STANDARDS FOR THE SMART HOME: DECT ULTRA LOW ENERGY Standard overview and future standarization needs
Angel Bóveda Wireless Partners S.L.
ETSI Board member, co-leader of the IoT strategic group
ETSI Workshop on IoT in the Smart Home - 21-22 March 2016
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
A central Home Gateway provides ULE radio coverage for the Home Network
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

Evolution and standardization needs
18
Identified gaps and standardization needs in the immediate future:
Focused on the Smart Home scenario
Evolution and standardization needs
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
Evolution and standardization needs
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
Evolution and standardization needs
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
Evolution and standardization needs
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

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
