Enhanced Consumers Experience

• To enhance consumers experience with home
  automation, all devices in the home need to
  integrate seamlessly with computer and A/V
  network.
• Examples of all devices
• Of course, computers, printers, PDAs, Cell
  Phones, A/Vs
• And non-IP devices light switches, thermostats,
  occupancy sensors, security sensors, etc.

3
Seamless Integration?

• What is seamless integration for consumers
• Zero-configuration, "invisible" networking, and
  automatic discovery
• A breadth of device categories from a wide range
  of vendors.
• Dynamically join a network, obtain an IP address,
  convey its capabilities, and learn about the
  presence and capabilities of other devices
• Same experience with UPnP devices and non-IP
  devices

Interaction bridge UPnP devices
UPnP
Interoperable open standard ANSI/CEA 709.1
5
Why do you need a Bridge

• Prohibitively expensive to implement UPnP stack
  in everyday devices such as light switches,
  thermostats etc.
• Ability to connect with largely deployed legacy
  networks.
• Connects UPnP devices and control points with non
  IP devices

6
Requirements for Non IP device Fabric

• True Open System
• Standards-based interoperable technology
• Multiple subsystems, multiple product vendors,
  multiple integrators, multiple user interfaces,
  multiple markets.
• Interoperable
• Freedom to choose best of breed products from
  multiple vendors and have them work together.
• Ability to enhance home over time without being
  locked into a single vendor or support contractor.

7
Requirements for Non IP device Fabric(Cont)

• Scalability
• Number of devices per network, flexibility of
  deciding media types, mixing and matching of
  different mediums.
• Power Line, twisted pair, fiber optic, RF, etc
• Distributed control systems with peer-to-peer
  communications (direct communications among
  transducers without mediation by a master).
• Cost Savings
• Lower product cost, installation costs,
  life-cycle costs.

8
Requirements for Non IP device Fabric(Cont)

• Built-in Security
• Low overhead built-in security.
• Time to Market
• Faster implementation of newly developed and
  fully optimized End-to-End solution products and
  tools.

Pervasive Network Statistics

• LonWoRks technology from Echelon is the most
  widely used network in the world for home
  building automation
• Over 30 million LonWorks devices installed
  worldwide
• Wide range of LonWorks products available from
  thousands of manufacturers
• LonMark Interoperability Associations
• Industry groups define how products work together
• Certification program has approved 500 devices
  certification centers located worldwide.

Solution - Architecture
UPnP Protocol
LNS Network Operating System

• LONWORKS Networks

11
Solution implementation

• LonWorks technology semantics LonMark
  functional object and network variables are
  defined at the application level (similar to
  UPnP functional profiles)
• LonMark objects are mapped into UPnP devices

12
Solution implementation details

• On any PC bridge application with Echelons
  LNS (LonWorks Network Services API) loaded in a
  server-independent mode
• All the mandatory network variables are mapped
  into UPnP stack
• Optional features (manufacturers specific
  extensions) can further be developed in the
  future
• Translator modules as Microsoft .Net assembly
  DLLs.

Software Architecture of LonWorks/ UPnP Bridge
14
Hardware adapters

• Possible solutions
• PL to Serial converter
• PL to Ethernet adapter
• i.Lon 10
• PL to Web Services Server
• i.Lon 100
• PL to PCI Bus
• PCLTA 20 SMX w/PLM 22

15
Conclusions

• With existing technology, everyday devices
  (LonWorks devices) can successfully be mapped
  into UPnP domain.
• Further work is required to commercialize the
  hardware and software bridge.
