Connectivity in lighting
• Why?
– Business case and Added value?
• Maintanance
• Control
• Usability
• How?
– Wired vs Wireless?
– Integrate existing standard?

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).

• Other wireless standards – WirelessHART
– DASH7
– EnOcean
– Z-Wave
– Etc…
– Proprietary
Wired technology
• Dali
• Ethernet
• KNX
• CAN
• RS485
• Etc…
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)

Example
Therapy luminaire
• 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.
