About the OpenAIS Reference Architecture:

Q: Is OpenAIS using RF or wired communication?
A: OpenAIS allows for both wired and wireless communication technologies, and for a mix of both within the same system.

Q: Are there restrictions to use OpenAIS specifications?
A: OpenAIS is based on open standards, it is an open document now and will be an open standard by itself.  The use of the OpenAIS label and the use of most of the stacks offered by vendors etc. may be copyright protected or bound to license fees, specific ruling regarding compatibility and alike. This is beyond our influence. The reference architecture is held as free as possible from protected knowledge, but this is not guaranteed.

Q: Are there sub-groups, supergroups and crossover-groups available?
A: OpenAIS Grouping is free from hierarchy, but may of course be used in a hierarchical way also.
Top

Q: Will the lighting response be fast enough?
A: Communication speed is dependent on the Physical Layer chosen. OpenAIS uses multicast messages to achieve fast reaction. This is the fastest possible transaction when it comes to address multiple devices in the same time.
Top

Q: Is an openAIS implementation costly?
A: There are no specific OpenAIS costs on top of the naked device and the communication (IPv6/CoAP) costs.
Top

Q: Are there extension API’s and SDK provided?
A: There will be required minimum extension API’s defined in OpenAIS. A more comprehensive API set and an SDK may be provided specifically by a vendor, OpenAIS specifies only the minimum requirements.
Top

Q: How does an OpenAIS system scale?
A: OpenAIS allows for local execution of local needs, and the incorporation of high(er) bandwidth backbone networks. Using these structural elements well in a given environment allows for nicely scaling systems.
Top 

Q: How does OpenAIS guarantee data privacy and system integrity?
A: The use of encrypted communication and well specified access levels allows for systems with in-depth data and integrity protection, also independent from the state of the site firewalls. To finally ensure this it is however necessary that the whole chain, from manufacturer to the final commissioner, needs to take care of credentials privacy issues, e.g. not using global commissioning passwords or alike.

Q: Is it difficult to commission an OpenAIS system?
A: The architecture is set in a way that tools can take large parts of the complexity of the IT and security related commissioning process. This will allow for easy to install and easy to commission systems.
Top

Q: Will there be a set of Apps that I can download to make my system respond better to my needs?
A: The OpenAIS Architecture allows for system and part system functionality upgrades after installation. There might be Apps, and plugins available that fit to the installed hardware, and also additional hardware that changes the available options once connected to the system.

Q: What happens to the lighting if a central device fails?
A: OpenAIS is prepared for graceful degradation, it allows for local controls to become active when the central controls (or the connection to the central controls) fails. Of course some of the central features may be missing in that case.
Top

Q: What is the minimum and the maximum size of an OpenAIS system?
A: There is no definite limitation embedded. A minimum system could consist of a preconfigured luminaire that has a LED output and a presence detector and a light sensor embedded. A maximum system could well cover a large campus with some 100.000 devices attached. However, for the larger systems some professional layout planning is advised.
Top

Q: Is there a way to integrate existing DALI or other heritage lighting controls into OpenAIS?
A: Existing lighting control systems may easily be integrated using (application level) gateways that provide limited or full access to the heritage system from the OpenAIS network. Please note that most existing lighting controls are (and will remain) restricted when it comes to extendability or full data integration.

Q: Isn´t it dangerous to have so many devices directly connected to the internet (IPv6 to the end node), since this would increase the probability of an attack)?
A: OpenAIS uses state-of-the art security mechanisms to reduce the system vulnerability as much as possible. We are confident that the benefits will outweigh that threat.
Top

Q: How do we see 5G in comparison with our approach, they are going for a similar solution?
A: Yes we see that and right they might be able to connect indoor devices as well, but mobile communication systems are designed for other purposes and some aspects might not really fit our use case, therefore we might be better positioned. We see the 5G dependency on the real-time cloud connection for simple light switching as a limiting factor.
Top

Q: How can OpenAIS as a research project have impact to so many other initiatives in the IoT arena?
A: Yes, there are many other initiatives, we watch continuously on which we can build upon and do the selection for the market,  We concentrate our research on the issues that prevented professional lighting control using IP communication up to today. We have established a liaison with Fairhair and please follow us for more.  Many partners are involved in other alliances ,like TCLA to  make sure that we do not loose connection to the rest of the world.

About the consortium:

Q: Can I join the consortium?
A: No, the consortium is closed by Horizon 2020 contract of the European Union. Results will be published on the OpenAIS public website www.openais.eu or disseminated via conferences and papers announced there. Once a related industry consortium is founded that drives standardization and testing of OpenAIS further this consortium may be joined. Please stay informed by checking our website.

Q: Where can I get more information?
A: .Results will be published on the OpenAIS public website www.openais.eu or disseminated on conferences announced in the news sections.
