A computer calculates the most efficient sequence for the way in which workers have to pick up the goods on the shelves. On the goods to select messages are sent continuously to the PDA that carry workers.

Stacks of paper containing the lists of goods to pick up have been replaced by messages simple and updated from a computer. The warehouse workers now collected three times more freight throughout the day than before the introduction of this system. And it is an industrial wireless network - transmission of information of the computer system to the PDA-that makes all this possible.

Elko store contains large amount of steel and cement. Corners and beams. And long distances. Signals of a traditional wireless network, such as those typically found in Norwegian homes, do not have sufficient scope here. And if the signals fail to function, providers do not receive their goods and Elko loses money. The company depends on wireless signals that cover installations through a reliable wireless network, regardless of the conditions of work.

Elko has opted to acquire this wireless technology provider Goodtech Products, Prosoft Technology's representative at Norway. Around of 20 powerful boxes hanging beams in the ceiling in the production plant and a warehouse. They transmit wireless signals in the presence of any obstacle. They are industrial routers that can tolerate heavy use and are very durable. Elko recently had to replace one of these boxes, but this was due to that a fork-lift truck of 4 tons he collided with it.
