IP-BLiS Vision & Goal
Our VISION

To make commercial
buildings more responsive tothe needs of users bypromoting a secure, multistandard, IP-basedharmonized IoT solution

OUR GOAL

Harmonization of access toan IP network with connectedbuilding automation products
allowing for better integration

Benefits of IP-BLiS
Single IP Backbone For all building automation products: IP (IPV6)
Common Security Allows common security in building networks
Eases IT department’s ability to support, eliminates need to know
Simplified Support & Administration application
protocol for building automation products
Seamlessly integrates wired and wireless connectivity
Seamless Connectivity Options options
to reduce installation costs
Uses Common IP networks to allow for monitoring groups ofDevice Groups & Policies Possible devices
instead of single devices

Scalability Offers limitless scalability & simple cloud integration
Potentially enables common semantic interpretation ofApplication data
independent from the used application protocol

Each domain requires agateway (GW) to translate
proprietary protocols into IP.
The building administrator
has limited control overindividual device in eachdomain, and provisioning iscomplex.

PROBLEM: Why convergence on theapplication layer doesn’t (always) work
One sharedgateway to translate
protocol into IP. GW
needs to be managed
and trusted by allverticals
simultaneously.

 Interdependencies between verticals
 Locked into one ecosystem Difficult to agree on roles & responsibilities Limited product choice / Vendor lock-in
 Less scalable No end-to-end encryption (trusted gateway) May end up with multiple networks

Buildings have become IP driven
The Future of IoT in Home and Building Automation►Smart Homes & Buildings become intelligent►The perspective changes from „inside“ to „outside“, i.e. there will be much more
external applications, which will use the data and functions of a building in a simple
way►Also „Smart Home & Building non-specialists“ will/must use this infrastructure►The semantic description of data will improve the provision of data and theinteroperability
