Wide open spaces like warehouses can mean trouble for wireless lighting networks. Node and point-to-point network systems can be cost-prohibitive because of the number of nodes or repeaters needed to operate a network in such a large space. A new wireless lighting control system is designed for warehouses and other spaces between 50,000 and 2 million square feet. The new system uses a mesh network in which signals are sent from unit to unit. There is no need for nodes or repeaters to enable information to travel longer distances from fixture to fixture. What's more, in a mesh network, if a signal is unable to penetrate an obstacle, the network finds an alternative route to get the command out. With node or point-to-point systems, walls, racks and other equipment could interfere with the network, causing pockets of non-service areas.

The new wireless lighting system is controlled with a computer software program or a hand-held remote control. Features include:

• On/off capability. Lights can be switched on or off all at once or in programmed zones, at specific times and dates.
• Dimming. Users control the amount of light output based on need.
• Occupancy sensing. One occupancy sensor can communicate with all fixtures, eliminating the need for sensors on individual fixtures.
• Re-zoning. Fixtures can be structured into new zones without rewiring.
