Frequently Asked Questions

What does 'TALQ' mean?

'TALQ' is just a name, not an abbreviation or acronym.

On business

What effect will this have on requirements for Outdoor Lighting Networks tenders?

The Consortium aims to simplify the tender process for outdoor lighting network projects for municipalities and lighting services as they will be able to refer to a standard management interface specification.

On the Consortium

What is the TALQ Consortium?

TALQ is a global consortium initiated by companies from the lighting industry, with the aim of creating a globally accepted open standard for a management software interface for outdoor lighting networks. 

Who are the founding companies of the TALQ Consortium?

The founding companies of the consortium are: Harvard Engineering, Kingsun, Philips, Schréder, Streetlight.Vision and Thorn/Zumtobel.

What are the Consortium’s activities?

The consortium activities are:

  • Development of the technical specification aimed at specifying an application language and protocol for operation and management of Outdoor Lighting Networks (OLN)
  • Joint promotion of the specification
  • Setting up and managing the compliance process

Why is standardization necessary?

We have analyzed the obstacles for the Outdoor Lighting Network market to develop, and lack of a standard is one of the reasons why some municipalities are not willing to deploy such systems at the moment.  We feel we can grow the total market by establishing a standard, which should be of interest to all stakeholders.

What is the TALQ Consortium’s scope?

The scope of the Consortium is:

  • The TALQ Consortium will standardize the application protocol at the interface between the Central Management System and Outdoor Lighting Networks.
  • TALQ will deliver a software protocol specification for this interface that covers parameters and behavior of end-points at the OLN and CMS side, needed for interoperability at application level.
  • TALQ shall not specify any physical aspect of the connection or connectivity
  • TALQ shall not specify how to achieve the required illumination behavior
  • TALQ shall allow for vendor specific function or feature implementations of the local/segment controllers and management systems, fostering competition and differentiation of vendors

How is the TALQ Consortium organized?

The members form the General Assembly. The Regular Members elect the Steering Committee to oversee all activities of the Consortium. The Secretary General runs the day to day activities and reports to the Steering Committee and General Assembly. The ‘Technical Work Group’ develops the technical specification(s), and the 'Certification Work Group' is in charge of defining the certification policy an compliance tests. The ‘Promotion Work Group’ takes care of the promotional activities of the consortium. All is supervised by the ‘General Assembly’. 

Will the Consortium membership be open to all?

Every legal entity willing to contribute to and promote the TALQ specification(s), can join as Regular Member.
Associate Membership is open to persons and legal entities with an interest in the objectives of the Consortium.

Will all members have equal access to all activities?

Regular Members have the right to access all activities. Associate Members have access to the General Assembly without voting rights, have the right to comment on draft TALQ Specification(s) and can join the Promotion Work Group.  

What cost is involved to participate in the Consortium?

The membership fee depends on the membership type, Regular or Associate membership. Current membership fees are available upon request.

How often does the TALQ Consortium meet?

The Consortium organizes face to face meetings regularly, as often as the members see fit to achieve the objective of  a standard management interface protocol for Outdoor Lighting Networks in an efficient and rapid way.  Currently  face to face technical meetings are arranged about every two months.

Where will the Consortium meet?

The consortium aims to hold meetings hosted by members, with meeting locations rotating according to the geographical distribution of the global membership.

On the TALQ Specification

How can I get access to the TALQ Specification?

The TALQ Specification is available to members of the TALQ Consortium, both Regular as well as Associate Members.

What is the exact definition of the TALQ interface?

The TALQ interface is an open software (application layer) protocol. It can be implemented in different devices that are used in the systems.  The TALQ interface makes sure that different devices understand each other, since they talk the same 'language'.

What is the scope of the TALQ Specification?

The TALQ Specification specifies an application language and protocol for operation and management of Outdoor Lighting Networks (OLN). This has been identified and confirmed by customers and key players in the lighting industry as one of the needs to be addressed to increase the market of OLN solutions

What is the definition of an Outdoor Lighting Network (OLN)?          

A communication network of outdoor devices such as Light Points controllers, Gateways, Segment Controllers, Sensors, for purpose of saving energy and maintenance optimization. 

What is the definition of a Central Management System (CMS)?

A device (whether hardware, software or combination thereof) which communicates with the OLNs to remotely configure and operate the OLN’s components. 

What do you consider a Central Management System?

Think of a Central Management System as an application server providing web or PC based user interface able to manage the lighting infrastructure (e.g. assets, schedules, manual overrides, alarm triggers), and monitor the operating conditions (e.g. burning hours, voltages, failures) and performance reports (maintenance, energy consumption).

Why is TALQ restricted to an application specification?

A major obstacle for the Outdoor Lighting Network market to overcome is the lack of a single protocol to manage various outdoor lighting networks. Because of this, customers such as municipalities, hesitate to invest in new technologies. A standard management interface protocol needs to support various kinds of network technologies, be it wired or wireless, to provide customers with a broad varitety of vendors as possible choice to overcome the fear of being locked-in.

Which requirements does the specification satisfy?

TALQ Specifications have to satisfy requirements defined in TALQ Specification Requirements documents that capture the minimum requirements of customers, such as municipalities. The specification has to overcome the current fear of dependent on one supplier. It includes features of lamp operation (such as dimming control), feedback (such as reporting of lamp status) and configuration (in order to set-up the system).

Will the TALQ Specification be submitted to a formal Standardization Consortium?

We believe a submission of the specification to a formal standardization organization will aid the adoption of the specification as a standard. Municipalities will be more encouraged to require equipment to be compliant with a specification endorsed by a formal standardization organization.
