Challenges of connected lighting

• Connected: – Luminaires

– Swiches

– sensors

• Multiple platform interface – Switch (sensor, user)

– App/cloud/website

– Other

• Gateway to: – Internet

– Smartphone

– Building management system

– Other

7

What kind of networks?

• Network types

– Point to point

– Mesh

– Star

– Ring

– Bus

8

Selection criteria

• Important to make good use cases

– Focus from customer point of view

– Problem domain, not solution domain

• Who uses the product

• How is a product used

• What if (a part of) the interface fails

– This will also create explicit and necessary

input for agile development

9

Wired or wireless?

• There is no “one size fits all”

• Criteria:

– New or existing infrastructure

– Data rate

– Power requirements

– Professional or domestic

application

Wireless technologies

• WiFi

• Bluetooth

• Zigbee

• 6LoWPAN

• Myrianed

• Other protocols

11

Wifi

Pro Con

High data throughput Power consumption

Worldwide standard Unit price

Dependency on 3rd party access points

High software maintenance cost

12

• Wi-Fi, is a local area wireless technology that allows an electronic device to exchange data or connect to the internet using 2.4 GHz UHF and 5 GHz SHF radio waves.

• The Wi-Fi Alliance defines Wi-Fi as any "wireless local area network (WLAN) products that are based on the Institute of Electrical and Electronics Engineers' (IEEE) 802.11 standards“.

Bluetooth 4.0

Pro Con

Low power Limited range

Smartphone compatible Gateway needed for internet connection

Upcoming mesh networking Limited bandwith

Additional functions (Beacon)

13

• Bluetooth is a wireless technology standard for exchanging data over short

distances (using short-wavelength UHF radio waves in the ISM band from

2.4 to 2.485 GHz) from fixed and mobile devices. It can connect several

devices, overcoming problems of synchronization.

• The Smart Mesh study group has been created to define the Feature

Requirements for a Smart Mesh networking within the Bluetooth SIG. It is

expected that the initial FRD will concentrate on lighting.

Zigbee

Pro Con

Mesh networking Heavy stack (>60Kb)

Almost no inter operability

Gateway needed for outgoing connection

Issues if mesh > ~40 pieces (latency)

14

• ZigBee is a specification for a suite of high-level communication protocols

used to create personal area networks built from small, low-power digital

radios. ZigBee is based on an IEEE 802.15.4 standard. Though its low

power consumption limits transmission distances to 10–100 meters line-of-

sight, depending on power output and environmental characteristics, ZigBee

devices can transmit data over long distances by passing data through a

mesh network of intermediate devices to reach more distant ones.

6LoWPAN

Pro Con

IP adress for all nodes Same heavy stack as Zigbee (IEEE 802.15.4)

Backed by Google Backed by Google

15

• 6LoWPAN is an acronym of IPv6 over Low power Wireless Personal Area

Networks.

• The 6LoWPAN concept originated from the idea that "the Internet Protocol

could and should be applied even to the smallest devices,“ and that low-

power devices with limited processing capabilities should be able to

participate in the Internet of Things.

Myrianed

Pro Con

Mesh networking No major companies involved (yet)

Self organising

Build by FHI members

16

• MyriaNed is a wireless sensor network (WSN) platform developed by

DevLab. It uses an epidemic communication style based on standard radio

broadcasting. This approach reflects the way humans interact, which is

called gossiping. Messages are sent periodically and received by adjoining

neighbors. Each message is repeated and duplicated towards all nodes that

span the network, it spreads like a virus (hence the term epidemic

communication).

18

Pro Con

Fixed connection

Material cost

Many options Complex installation

DALI

Pro Con

Simple protocol Limited number of devices (<64)

Low cost components

19

• A DALI network consists of a controller and one or more lighting devices

(e.g., electrical ballasts and dimmers) that have DALI interfaces. The

controller can monitor and control each light by means of a bi-directional

data exchange. The DALI protocol permits devices to be individually

addressed and it also incorporates Group and Scene broadcast messages

to simultaneously address multiple devices (e.g., "Group 1 goto 100%" or

"Recall Scene 1").

Ethernet

Pro Con

Well known protocol Heavy software and hardware requirements

IP communications

Power over ethernet

20

• A DALI network consists of a controller and one or more lighting devices

(e.g., electrical ballasts and dimmers) that have DALI interfaces. The

controller can monitor and control each light by means of a bi-directional

data exchange. The DALI protocol permits devices to be individually

addressed and it also incorporates Group and Scene broadcast messages

to simultaneously address multiple devices (e.g., "Group 1 goto 100%" or

"Recall Scene 1").

KNX

Pro Con

~ 350 member companies Complex installation

Many COTS components Licencing model by KNX association

21

• KNX is a standardized (EN 50090, ISO/IEC 14543), OSI-based network

communications protocol for intelligent buildings. KNX is the successor to,

and convergence of, three previous standards: the European Home

Systems Protocol (EHS), BatiBUS, and the European Installation Bus (EIB

or Instabus). The KNX standard is administered by the KNX Association.

There will always be cables

In the foreseeable future wires are needed for power anyway

22

What will the future bring? • Bottom up architectures will prevail • Replacement of 240V infrastructure? • All products will become intelligent and connected

What can Metatronics do for you?

• Create full service hybrid systems

– Led solutions

– Sensor solutions

– Human interface solutions

– Networking solutions (both wired and wireless)

• Dual platform interface (product and app)

• Minimal interface on product, all intelligence in app

• Single touch solution on product

– Top of product is touch sensitive.
