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, simple to deploy and to use, 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, an 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 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 form factor of the Gateway, there is a choice between compact and DIN-rail, while for the system hub (sometimes called command and control center) the choice is between using VEhub or a customer’s owned hub.
The elements of an E2D system are: 1 VEhub or customer hub, any number of E2D wireless networks, with one Gateway per network, and any number of Bridges for up to 16,000 luminaires per network.
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.
