  The systems based on intelligent sensors are currently expanding, due to
theirs functions and theirs performances of intelligence: transmitting and
receiving data in real-time, computation and processing algorithms, metrology
remote, diagnostics, automation and storage measurements...The radio frequency
wireless communication with its multitude offers a better solution for data
traffic in this kind of systems. The mains objectives of this paper is to
present a solution of the problem related to the selection criteria of a better
wireless communication technology face up to the constraints imposed by the
intended application and the evaluation of its key features. The comparison
between the different wireless technologies (Wi-Fi, Wi-Max, UWB, Bluetooth,
ZigBee, ZigBeeIP, GSM/GPRS) focuses on their performance which depends on the
areas of utilization. Furthermore, it shows the limits of their
characteristics. Study findings can be used by the developers/ engineers to
deduce the optimal mode to integrate and to operate a system that guarantees
quality of communication, minimizing energy consumption, reducing the
implementation cost and avoiding time constraints.
