This consists of one or more HUBs which communicate with each other through a 5GHz band wireless network.

• Each HUB can select and self-adjust the working channel and transmission poweraccording to the loads in the network and the environmental conditions, in other words:
A change in the layout of the sales point or the repositioning of a product does not require any activity on the part of the personnel: the system will adapt to the new conditions.

• The HUBs are designed with the plug&play system: in the event of a fault only the HUB has to be changed, nothing else.

• Each HUB has a back-up battery with 30 min. operating time: a power failure or lost connection to the server is not a problem.
