Designed and capable to replace any part of a DALI system wiring by wireless, VEmesh Wireless Extension to DALI (or D2D, for DALI to DALI) is deceptively simple and offers ultimate flexibility.
A D2D wireless network is formed by one VEmesh Gateway and a number of Bridges. The Gateway connects anywhere on the DALI bus, usually next to the DALI Master. The VEmesh Bridge connects to the various DALI devices, with each VEmesh Bridge capable to support up to 8 DALI addresses. The Gateway supports up to 64 Bridges, and up to 64 DALI devices. The Gateway and the Bridge Nodes do not require a DALI address of their own.
In large deployments, up to 250 VEmesh D2D networks can operate in the same area; in large areas more networks can be deployed by frequency re-use. A VEmesh Toolkit is available to speed up the deployment and the maintenance.
The elements of a D2D network are: 1 Gateway, 1 to 64 Bridges and the optional VEtoolkit.
VEmesh IoT Extension to DALI (or E2D, for Ethernet to DALI) is a Smart Lighting control system, which is simple to deploy and to use, and it’s either stand alone or part of a Smart City system.
An E2D system is formed by one VEhub and a number of E2D wireless networks. In turn, each E2D wireless network is formed by one VEmesh Gateway and a number of Bridges. The Gateway connects to a standard Internet router for cloud control (such as via GPRS) or to a local server. The VEmesh Bridge, in various form factors, such as internal, or Zhaga, connects to standard DALI LED or other types of luminaires, or to sensors or actuators as required in a modern Smart City lighting system.
The Gateway can form networks of up to 16,000 luminaires, as opposed to DALI limitation of 64 devices per loop. For the system hub, the choice is between using VEhub or a customer’s CMS (Central Management System).
An E2D system comprises one VEhub (or customer’s CMS) and up to 250 VEmesh E2D wireless networks. In turn, each network requires one Gateway, and can support any number of Bridges for up to 16,000 devices, such as luminaires or sensors.
With high robustness and resiliency, low and deterministic latency, high range, practically unlimited number of Nodes and Hops per network, VEmesh is the optimal technology for wireless lighting control of streetlight and professional lighting, as well as for similar applications that require high performance wireless networks.
A VEmesh wireless network is formed by one VEmesh Gateway and an unlimited number of Node modules. The Gateway connects to the user’s remote or local management hub, with a choice between UART, USB and TCP/IP types of connectivity. To low and medium volume Nodes’ customers we offer VEmesh modules, while to the high volume customers we also offer the VE209 IC controllers, thus enabling you to design your own devices. In deployments with a large number of VEmesh networks dedicated VEtoolkit can be used to speed up the deployment and maintenance.
The elements of a VEmesh network are: 1 Gateway, any number of Nodes – modules or controllers, and 1 VEtoolkit (optional; more than one can be used).
Virtual Extension offers Starter Kits of its various families of products, for the users to be able to check VEmesh suitability to their very applications. Each Starter Kit is usually comprised of on Gateway and several Nodes (or Bridges) of the respective family of products.
Virtual Extension is certified to act according to ISO 9001:2015 Quality Management System, for the development, manufacturing and marketing of its VEmesh wireless networks. The last ratification by the Standards Institution of Israel, an IQnet partner (International Certification Network), has been recently extended until 31 October 2021.
