Abstract

In this paper the architectural design of a measurement system for remote sensing, based on ad hoc Wireless Local Area Network (WLAN) concept is proposed. The system is conceived as a Code Division Multiple Access (CDMA) Spread Spectrum (SS) network operating in the unlicensed Industrial–Scientific–Medical (ISM) frequency band (2.4–2.5 GHz). It makes use of a specific and extremely simplified communication protocol, whose characteristics allow simple implementation, without preventing advantage being taken of the processing gain associated with the waveforms. The most meaningful aspects strictly related to the design of the critical element of the system, the modem, are discussed and the hardware solutions are presented. Finally, the results descending from both simulation and experimental test activities, performed on some critical functional blocks of a couple of prototypes under design, are discussed.
