Niels Thybo Johansen CTO, Zensys

Introduction

Z-Wave = ONLY interoperable market success for wireless HAN– Established in the market, 300 products, 200 companies, various

channels, many application all INTEROPERABLEZ W f t t i HAN b ti d ll t th l t ilZ-Wave for smart metering HAN can be tied well to other last mile solutions via bridge architecture as well as integrated to IP via Z/IP– Horstmann and Trilliant products / examples / demo’s

Z-Wave’s ecosystem in the UK (HVAC & lighting) can be greatly leveraged for energy display– A Horstmann or Danfoss thermostat can double duty as an energy

display and reduce utilities investments on the display roll-out


Z-Wave is being opened up through collaboration with Cisco in the Z-Wave alliance and the convergence with IP in Z/IPZ-Wave will have 2nd source silicon through the investment of Panasonic in ZensysZ-Wave has a new full device class for smart metering

What you need to know

Zensys has always focused on the network / ecosystem first before driving the gateways (smart meters)In the UK the key light control companies and HVAC companies have Z-Wave products or will have them soon– It does not make any sense to be the only fax machine in a network– Would love to introduce these UK companies to let them tell why

they chose Z-Wave and what they can do for youZ-Wave has roll-out and trials in smart metering (Horstmann, Modstroem, DEST) but have not yet been beating the PR drum.Z-Wave contains all IP needed for HAN


Z Wave contains all IP needed for HAN– Avoid IP infringement lawsuits during trails and roll out – as seen

recently in rollout in Southern California.Z-Wave operates on the well regulated 868MHz band – No interference from WiFi!

The Z-Wave AEC VisionWhy create a new ‘Monster’?

Leverage on the existing flexible Z-Wave technology!

Why create new classes of ‘Smart’ appliances?L t l th i ti d i ti l d h ddi d t t tti t– Lets leverage on the many existing devices supporting load shedding and temperature setting etc.

– Lets leverage on the many existing devices supporting sub-metering – The intuitive way for Consumption analysis

– Then - Allow manufactures to enrich their products – No new SKUs which cannot be used with other initiatives – to implement even better energy conservation mechanisms going forward.

Why create new classes of ‘information displays’?– Lets use the displays already in Z-wave products – such as remote controllers and thermostats– Then - Allow manufactures to add the strong Z-Wave security options to protect sensitive data

Why re-invent Security and Remote Home Access strategies?


Why re-invent Security and Remote Home Access strategies?– Lets use IP or other WAN technologies – providing the last mile communication, an excellent and

proven quality of Service and mature Security (like SSL or TLS)– Then - Allow manufactures and Utility Suppliers to leverage on their IP knowledge and enrich

existing backend application and IP Gateways

Instead, lets focus on the important NEW problem to solve !– Create a scalable data distribution architecture for ALL devices. Whether low-cost or High-end.

ZigBee Architecture

■ZigBee is built on top of the IEEE 802.15.4 standard for MAC + PHY

■ It includes a networking layer (NWK) for routing g y ( ) getc. and an application support layer (APS) as well as configuration (ZDO) and security services (SSP).

■ZigBee also includes application profiles (APP) which provide definition of devices and messaging, and ensure interoperability.

Not all standards and technologies do this!■Some other technologies and standards ONLY

define the MAC+PHY layers, or perhaps also the NWK layer, but no more.

Security ZigBee chips have the computing power and, at 2.4GHz, the bandwidth to support the level of security that utilities demand for AMI and SE. A high level of security is built into the standard.

Upgradability ZigBee chips support over the air upgrades, whereas many other wireless solutions do not, and some could not!

Cost Considering ZigBee’s extra capabilities over other solutions, the cost differential is small and improving as the market takes off.

Open Standard ZigBee is clearly an open global standard, whereas many other technologies are not.

Silicon Vendors Utilities and meter manufacturers want multiple competitive suppliers of components to support their projects for 20+ years


suppliers of components to support their projects for 20+ years. ZigBee clearly delivers this, with 22 compliant platforms.

Energy Application

ZigBee has an application profile designed specifically for SE, whereas other technologies do not have this.

Interference ZigBee is designed to handle interference, and often co-exists with e.g. WiFi in the same device, whereas other technologies degrade quickly in the face of RF interference.

17

ZigBee also offers…

■Scalability to thousands of nodes, which makes it possible for instance to do last mile communications, as

ll l l i tiwell as local communications.

■Flexibility, allowing manufacturers to have devices which have multiple endpoints (similar to IP ports), some of which support standard communications (e.g. ZSE), others which may support private protocols, thus allowing for innovation and differentiation in the market, as well as


standardisation.

■Interoperability and Cooperation with other technologies and standards, e.g. ongoing work with HomePlug Alliance to support ZigBee Smart Energy across wired as well as wireless networks.

18

10

ZigBee at 2.4GHz is future proof

■Platforms by top silicon vendors and fab-less start-ups

■Products by numerous top meter manufacturers and electronics y pmanufacturers

■Driven by a board of directors that includes silicon vendors, meter manufacturers and electronics manufacturers

■Supported by 300 member companies

■Based on a proven radio standard, IEEE 802.15.4

■Good bandwidth availability for smart metering


y g

■Good coexistence with other technologies at 2.4GHz

■Over the air upgradability

■A standard that is mature in a market that is growing

PRI experience with ZigBee Smart Energy

■Multi source advantage of ZigBee

►PRI have used ZigBee solutions from four►PRI have used ZigBee solutions from four different silicon and stack providers for product developments. Changing platform provider has been relatively easy.

►The first batch ZigBee Smart Energy certified products are on both TI and Ember platforms. Some use application builder others are home


Some use application builder others are home grown implementations


■Smart Energy development►Profile has been developed by a consortium►Profile has been developed by a consortium

made up of the world’s major metering companies as well as home control and data management providers.

►The test specification was itself tested during as part of the Profile approvals events to ensure test harnesses and methods were de-bugged.


►Security was a big concern with the utilities, additional PKI security had to be added to satisfy utility requirements for key exchange.

13

PRI experience with ZigBee Smart Energy■ Smart Energy development (continued)

►Four pre-test events were held to ensure the specifications were correct and un ambiguouscorrect and un-ambiguous.

►The certification event required participants to show interoperability between at least two other platforms plus a test harness.

Devices included:– Electricity & Gas meters and Energy Service Portals– Displays

Thermostats

Trilliant view of ZigBee and ZigBee Smart Energy

By Kevin House, Trilliant


y e ouse, a t


What do we know?

Trilliant’s credentials: Leading global supplier of smart metering, in-home (demand response) and smart grid solutions, built upon open standards

Developer of RF mesh solutions, utilising IEEE802.15.4 chipsetsOne of the larger individual users of these chips at present (>750k meters deployed)

Supplier of the largest RF mesh deployment in the world*

Open advocate of systems and platform interoperability, supporting various HAN alternatives, including ZigBee

Key contributor to creation of ZigBee Smart Energy Profile

Developer of a full-specification, certified ZigBee Energy Services Portal


28

First to demonstrate working prototypes in early 2007

Achieved full certification on the inaugural certification day

Has demonstrated interoperability with various ZigBee device manufacturers

*as far as we know ☺

15

Trilliant experience and opinions of ZigBee

Open standard IEEE802.15.4 at 2.4GHz is an excellent physical foundationWe chose it too ☺

Ideal combination of design parameters for smart energy and HAN purposes

‘Open silicon’ - supplier diversity for chips, from many manufacturers

Access to expansive developer community, which will continue to advance it

ZigBee has the potential to utilise external advances in IEEE802.15.4

ZigBee offers a full stack solution – including application profile for energy

ZigBee Smart Energy Profile provides fairly thorough coverage for initial energy-related in-home needs

Early days. Will continue to develop and expand with market requirements and


29

innovationsRecent experience of integrating additional Victoria requirements was very positive

Low typical power levels may present difficulties in certain physical scenarios e.g. high-rises, but this can be overcome with creative techniques

Evaluating ZigBee for the UK – Trilliant’s view

ZigBee appears to be a very credible contenderDelivers on the majority of requirements, and should be able to incorporate the remainder, including room to extend

Has strong backing from large community (including Trilliant)Has strong backing from large community (including Trilliant)

We don’t believe you need to lock the UK into a single choiceThere is room for multiple options

The cost of keeping options open is less than the cost of choosing (poorly)

ZigBee and others can coexist and could even interoperate

Support the development of multiple options, and others that will appear in future

Get involved in their working groups and help lead their evolution


30

Get involved in their working groups and help lead their evolution

The marketplace will deliver the best options if given the opportunity

But if you must chooseBe sure to pick a strong physical platform, so you have the option to evolve

ZigBee in UK Homes


Alertme Experience

31

ZigBee Experience in UK Homes - Alertme

■Thousands of ZigBee nodes in UK homes►No interference problems, very few range issues

►All customers self-install with online instructions► custo e s se sta t o e st uct o s

►No support calls generated by installation process

■Full coverage in 80% of homes with single-hop transmission►Coordinator on ground floor, transmitting at +5dBm (unamplified)

►Sensor nodes transmitting at +3dBm (unamplified)

► Isotropic chip antenna on all nodes (suboptimal for range)

■5 years battery life for sensor nodes sending heartbeat every 2 minutes


■5 years battery life for sensor nodes sending heartbeat every 2 minutes►850mAh LiMn02 CR2 battery

■Experimented with nodes where meter normally resides► Indoor meter location, no issues, connectivity always good

►Outdoor meter location, worked most of the time, periods of poor connectivity

32

17

Alertme – Suggestions for UK Smart Meters using ZigBee

ZigBee user experience is good, self-installation is easy

ZigBee propagation in UK homes is generally good even if not transmitting at maximum permitted power levels and even if not relying on mesh network for propagation.

To minimise connectivity problems from smart meters located outside the home;


■Add PA to amplify TX power to +10dBm (10mW)►perhaps also use LNA in meter node

■Choose antenna to maximise range

1. Overview Frequency Assignment / Radio Propagation






Content



- IEEE802.15.4 / ZigBee mechanisms enhancing coexistence (1):

1. CCA using CS and ED

- Collision avoidance mechanism (CSMA-CA), applied to 2.4G and sub-1 GHz

- ED and LQI are measurements used for CSMA-CA to characterize interference situations

2. Dynamic Channel Selection

- Not required for 868 MHz

- Mandatory for 2.4 GHz – requires resources and time, increase power consumption

- ChannelList parameters are to be adapted for varying interference scenarios

- Adaptive Frequency Hopping is not likely to implement due to limited channels (16)

3. Modulations schemes

- 2.4 GHz O-QPSK (sine shaped, MSK equivalent) allows a power-efficient modulation scheme

- Sub-1 GHz bands using bandwidth limited modulation schemes

- 868 MHz is not affected by adjacent/alternate channel interferences

- 915 MHz has typically a higher selectivity due to narrowband characteristic

Coexistence (1)

Coexistence / Interferences (1)


- IEEE802.15.4 / ZigBee mechanisms enhancing coexistence (2):

4. Low duty cycle

- IEEE802.15.4 specification is tailored for application with low power and low data rate

- Typical applications are anticipated to run with low duty cycle as well

- A low duty cycle reduces the risk of interferences

- Battery operated devices suffer from increasing duty cycle

5. Channel alignment

- Not required for 868 MHz

- Mandatory for 2.4 GHz – requires resources and time, increase power consumption

- 2.4 GHz channel alignment reduces the number of available channels significantly

- 4 out of 16 channels in guard bands between 802.11b

- Interferences in guard bands are likely due 802.11 TX side lobes

6. Low transmit power

- Applicable to all 802.15.4 bands

- Sub-1 GHz systems are likely to operate at lower power because of

- Better propagation conditions, and

- Less interferences

1. Overview Radio Propagation / Frequency Assignment






Content



- A ZigBee network installation requires knowledge about propagation conditions and environmental interference situations

- A link budget calculation is a first estimate to compare IEEE 802.15.4 implementations

- The link budget takes technical parameters of the system into account, like

- Receiver sensitivity

- Transmit Power

- Antenna Gain

- The calculation of a certain path loss requires further knowledge about the operating frequency of the network

- Operating frequency sub-1 GHz vs. 2.4 GHz

Propagation Environment



- A simple model is used to determine the loss in a transmission link that would be expected under Free Space Conditions (direct-ray model)

- Free space condition assumes an ideal environment without any objects that absorb or reflect any radio energy of the transmitter or receiver

- A free space loss calculation based on Friis transmission equation calculates the TX power flux density to determine the received power:

- The path loss Lpath is calculated as the relation between received and transmitted power:

- Exemplary, a comparison between IEEE802.15.4 implementations is shown to emphasize the effect of different ISM frequency bands

Conclusion: sub-1 GHz adds to IEEE 802.15.4 systems

• Increased range due to the lower frequency band, and

• increased sensitivity by running a lower data rate

- A free space model does not assume any impact of reflection, diffraction or multipath

- Multipath (multi-ray) is a typical scenario for wireless private area networks

- A 1st order multipath model assumes the impact of a ground wave as it is expected for systems operating in conventional environments



868 MHz

2.4 GHz

- Multipath scenarios shows partly a significant increase of the path loss caused by destructive characteristic of various signal paths

- 868 MHz is more robust against signal degradation

multipath

LOS


- Phenomena's affecting the wave propagation are:

- Multipath propagation

- Operation of WPANs in buildings is characterized by multipath

- Causes of multipath are reflections, refractions and attenuation by walls, furniture and other equipment

- Effects of multipath are constructive or destructive, phase shift or attenuation

- Effects vary over time by changing the setup or varying operational conditions

- Absorption by liquids or gases

- H2O absorbs energy caused by the high molecular dipole moment of the water molecules, critical for 2.4 GHz operation => “water meter operation”

Conclusion

A sub-1 GHz WPAN is less affected by

multipath propagation and absorption effects


Other Propagation Effects
