Following the deregulation of broadband radio in Europe in the nineties, the spread-spectrum modulation technology has become widely used for the transmission of data in logistics.Broadband radio data communication has characteristics which make it ideal for the connection to existing networks.In the 13-cm band (2,4000 to 2,4835 GHz) of broadband radio, this spread-spectrum technology allows for the transmission of larger data volumes as compared to narrow-band radio.There are two methods to be used in spread spectrum: the frequency hopping method and the direct sequence method. The two methods are very different, and they are unable to communicate within the same installation.By establishing binding specifications for wireless networks (IEEE 802.11), a standard has been created which allows manufacturer-independent application.This paper offers a survey of the technology and the specifics of broadband radio systems, giving particular consideration to its application in production and stockholding.
