Pick-to-Light with wireless networks

Fixed light consoles on distribution centre rackings is common. It is used for piece picking of fast moving products. By picking from where it is lit up, one doesn't need to remember where what products are stored.

The drawback of such systems is investment into the hardware, software and cabling is significant. One has the do product profile and pick projections very closely to decide how many "lights" needed, and it is not very flexible to changes.

With the process of wireless networks, it is now easy to identify nodes in a wireless network. As such, light modules can be fitted on such nodes to be lighted up, creating instant Pick-to-Light modules. With the Pareto rule, since only 20% of all products contribute to 80% of picks, one can just put the light modules on these popular products.
