Technologies for wireless data acquisition and monitoring of environmental parameters

Wireless technologies represent reliable and efficient solutions for remote data acquisition, supervisory and control systems. The correct selection of the proper transmission method from the wide variety of wireless radio transmission methods and standards represents an important issue. For this reason in the firs part of this paper are presented briefly, the newest and most efficient wireless technologies suitable for remote data acquisition and monitoring of environmental parameters. After that, the paper is focus on the GPRS method as solution for implementing such distributed systems. Are presented in detail the GM862 GSM/GPRS modules and the development boards used for tests.
